Great idea! i'm a gardener. And we like to start seedlings in the late winter. And for that we have "heat mats" that go under the plant modules to keep them warm, at about 25C. Guess where I keep mine the rest of the winter? Yep, on the floor under my chair and plugged in when I want heat. It draws just 17 watts and keeps the feet toasty warm. Because if your feet are warm, the rest of you stays much warmer. Keep up with the videos. Love what you are doing.
I have thought about using led lights to start veg off inside the house and letting the waste heat the house. That way the electricity does 2 jobs at once.
I always used the furnace and hot water heater closet for the purpose of germinating seeds. Gets plenty hot in there much love hope you’re all having a great day take care and talk to you soon
@@ThinkingandTinkering how do you connect it to your power source? Do you just use alligator clips on the copper to your power source?. Thanks happy Christmas,
Until now I was unaware of Dutch Stoves. Thanks for bringing it to our attention. I previously ran across a video where the host advised that adjustable heat mats used in terrariums and reptile tanks are both inexpensive and highly efficient and can be used to keep our feet warm. I have a small 8"x12' soapstone slab, which as many know is highly efficient at absorbing and slowly releasing heat. I now plan on using my soapstone slab as thermal mass and heating it with a heat mat within a DiY dutch stove. Warm layered clothing, a wool blanket, hot water bottles in bed and a DiY Dutch Stove should keep me warm and save on utility bills. PS: on a sunny day, I can heat up the soapstone slab in my Sun Oven and have a totally passive means of staying warm. Thanks again for the info.
I have giant very hard Basalt rocks and a giant cast iron wood stove. I covered the stove with the rocks and had 50° F house in the morning and a warm floor when it was 5° F outside. 8 hrs after the last time I filled the stove. There is only Juniper and Pine here for wood. They burn really hot but really fast. I am adding a lot more rock as soon as the snow andI Ice melts.Saves so much money!
@bina nocht hi just wanted to inform you that putting random stones on your wood stove is a bad idea. Stones that have not been cooked in a fire pit outside far from a home and yourself can explode sending shrapnel out everywhere. Please use cans of sand if you do not have stones that have been fired first. You could use terracotta pots they hold heat. We use fire tile edging and terracotta pots with candles underneath to heat our home.
@bina nocht : It might be worth your while to stop in to your local specialist stove shop, to pick their brains. If the chimney is getting hot and nothing else is, it could be something fairly simple, such as the damper being left wide open, or broken suchthat you can’t adjust it for airflow. Once you’ve got a good draft going, and you get your fire going, you shouldn’t need it open full bore. But it could be something more, for example, there’s a certain size pipe leading away from the stove that makes for efficient heat. If that pipe is too big for the size of your stove, the wood burns fast and The heat basically goes up the chimney without doing a whole lot for the temperature in the room. But it would probably take somebody with some training and experience to figure out if the pipe on your stove is right for your stove. There’s probably a whole lot more to know, and that’s why my suggestion is to go talk to those good folks, who might be able to do a great deal to help you get the most out of that stove.
Fantastic!! Excited to see a video on rheostats, voltage control and the like. I used to, as a lad, take broken stuff down to bits and experiment with the various components. Along with making my first simple electromagnet and learning to solder (then learning to solder correctly) I had hours of fun.
1. You get an old bike and turn it into the generator. 2. You get an old furniture and you turn it into this Dutch Stove. 3. When you pedal, you generate a power for the Dutch Stove, and, you keep healthy at the same time. You can swap with your family members to take turns even. A pure win-win for everyone :).
Or more simple . You take a bicycle wheel . Remove some of the spokes . Add a few hand made propeller blades . Mount the wheel on inverted bike forks that have been cut off and fixed below the steering column . Connect a a bike wheel dynamo . In South America I one witnessed a similar set up in a rapid moving river. blades were set up on the wheel more akin to a watermill .
@@paulmolyneaux5779 let's agree to disagree. :) 1. The dynamo has too much friction, the more friction the more loss you've got. Would be better to use static magnets on the wheel and coils outside if you don't like a generator ;). 2. When you remove some of the spokes, you know when you fix these things, that you take the wheel out of the balance. So, a better way would to be cover with some lightweight element though some of the spokes. 3. Now everyone has a water :D, so it would not work for everyone. Robert is trying solutions which are most universal.
@@screen-protector I agree entirely . Magnets work even better . In Scandinavia the bike wheels are fitted with a magnet at intervals around the rim . There are magnets mounted on the forks. When the magnets pass it sends a current to light the bikes LED's I guess it's all about what energy is making the wheel move. Harnessing nature or using peddle power . I always imagined what energy could be generated and stored, if every Gym's (such as 'Fit for Free)' training devices were hooked up to capture all that energy.
Another great vid 😀👍 We used to smelt aluminium and had three phase lathes plus all the power tools in woodwork when I was at school. All the kids do now is make things out of plastic with blunt tools or 3D print something. We’re a dying breed and a lot of them but not all will look to us when things get worse. 😎😀

I am a big fan of saving power. When a pot has come to the boil, I cover it with two old towels and set it aside to finish cooking in its residual heat. This method also helps to maintain the vitamin content. Straw lined boxes were used for the same purpose during WW2.
We use a single induction hob (in the summer) to heat a whistling kettle (so I don't forget!). We have a flask next to the kettle so once we have poured our cups, any left over goes in the flask to build up for at least a few more drinks. Now it's winter we have a kettle on the wood burner and it just happily sits there until it's boiling, then that water is used in the same way and left overs go in the flask. Free cups of tea all winter 🙂
I may offer some clarification. The Dutch Oven has a different meaning in the states. The Dutch Stove must be unique to places across the pond. I'm not familiar with it but I admire the repurposing. I don't understand the electrical part of it but I think I could build it. Liked the vid.
this looks like a project you could gut a simple old coffee maker for, coffee maker has everything you'd need inside for making it run. on/off switch, thermal switch, low power heating element.
Yes i was thinking of an old electric kettle and using all the electrics minus the element and using something like the the slab element as Mr Chuckle used there ?
USB heated Gillet, 2 usb power banks, thermal beanie, led head lamp and an electric over blanket job done you can even get USB heated insoles if you suffer from cold feet. I had the misfortune of spending a winter in a cottage with no central heating a friend lent us some one man tents to put over the beds was surprising how warm it got when shielded from the arctic blasts of air coming under the door and thru the "quaint" single glazed windows. Am contemplating making a space foil 4 poster bed might wake up thinking im the christmas turkey but will be warm 😀
I’ve just remembered I have my mother’s antique brass bed warmer. It was decorative in her house, hung by the fireplace, but it’s an iron dish, like a large round casserole dish size, with a brass perforated hinged lid. You put embers in there. The thing has a long metal handle, and looked like a wooden piece fitted on the end to not burn your hands. This would then be carried around the bedrooms at bed time, and inserted between the sheets where you’d lie, to warm it all up before you climb in. Not to use too many embers I suppose, so you don’t shake a spark out into your bed and be on fire by 3am! But it was a thing they did, apparently.
@@sassafrasred6657 ah, that does make sense. Thank you! Always have to cast about wondering for somewhere to put my cherry stones; now I know! I suppose plum stones and similar would also do
@@sassafrasred6657 Crushed walnut shells in a flannel bag, place in microwave for a minute or two (depending on the microwave). Toss into the foot of the bed. Easy peasy.
I bought three bottle shaped bed/babywarmers at a garage sale this summer. Fill it with hot water. limit contact heat with a pair of old socks. So ol' skool.
These videos are just great. Thank you so much! With your no nonsense manner, and something that reminds me of my Dad. He had natural physical skill, could just put his hand out and catch something falling, effortlessly, yet without being dainty about it. Your a Natch! A ‘natural’. With lots of study or practice behind it, I’ll be bound 😉. I used to find the maths behind physics a real challenge a school, but somehow “got” the principles. But I’d have done ok in you class, I’d like to think. Practical and relevant and interesting
Great video. I do a few house clearance jobs and use expensive cabinets for firewood all the time. Stuff like that is only worth what folks are prepared to pay. Keep up the good work. Cheers. Rob
the old Dutch stoves had a teracota inner pot with a glazed inner side that was the test. you placed glowing coals in the test that heated up the teracota pot and it gave off the heat
I think my grandmother had something like that. On a bigger scale it was in church where we went in my youth. Under your feet was a metal raster with embers underneath in the old days but I have never seen it work. I visited that church last year and that stoves were still there. I think when it needs to be they still can be used.
@@johne7100 : In the RC cathedral in the town where i lived, the pews only had a sturdy wooden hardwood 2x2 board across the back, at the height at which you would expect the top of the back of the pew to be, instead of a normal backrest on the pews like a person would normally expect to see on pews or even any chair at all. When I asked about that situation, I was told that sitting in the pew was considered to be part of penance, and it was to encourage people to stay alert and to sit up straight at all times. Lol. I imagine the cold church that you attended in Ireland, had some of the same sort of logic going on.
I am using a 240v 2.4Kw electric frypan as a “foot stool” heater. I’ve taken the Bakelite feet off it. It is upside down on a cushion on the floor. I have powered it via a 240v to 24v transformer. So I’m supplying 1/10th volts, this results in 1/100th power. 2400w becomes 24w. The thermostat still works, so I can adjust the temperature to nice and warm. With warm feet I’m warm all over and my heating cost has dropped by 2 orders of magnitude
Have lived in the Netherlands as a high school student. Knew elementary children had built similar stools at school to be used at home. The design was more like the ones seen in older paintings. It could hold a bowl of warm coals. In some Reformed churches there is a floor plate for the congregation who sits in the front pew. Hot water is circulated underneath and feels great during winter services.
Specifically targetted heating like this seems like a smart way to go. Get a little low-power heater and bundle up with a blanket or warm clothing and you can be comfortable with minimal additional cost. It gets very cold where I live; today's low temperature is -37°C and I am very thankful for central heating.
12 volt electric blanket guts, harvested and glued to a flat stone -- includes dial to regulate the temperature in your little tent, in a car, closet in a squat, pickup truck shell...
@@bella-bee Freedom of movement around in the little space. Gotta be doing more than reading or working the laptop for hours and hours. And the sleeping bag is actually more comfortable when at rest anyway. But yeah, it would seem like being wrapped in a reliably warm blanket would be the ticket -- until that ride doesn't go anywhere even nearby.
I found someone who suggested heat pads, as used in vivarium, for your lizard tank or whatever! Got it on Amazon, I chose a 14w version so it wasn’t too big (about a ft square). Yes it plugs in the mains, no adaptor, transformer, so you need the power on in the first place, but it’s cheeeeeap and keeps me nice and warm at my desk. Cuddle it, footwarmer, mouse mat etc. I sat on mine at my computer. Mini electric blanket even. If a lizard can sleep in it I suppose I can, but I don’t know whether it’s truly safe. So do your own research. I gather the bigger ones don’t get hotter, just a bigger area getting as hot, if that makes sense. It feels as hot but over a larger area. Google vivarium heater.
An old war time alternative is to fit a standard 230v light bulb socket into the lid centre of a large empty tin (metal) container about 8" dia x 10" long. Punch 3/8" dia holes around the tin to allow heat to escape. Put a 60W light bulb in the lid socket with bulb inside the tin. Obviously care needs to be taken as it's 230v mains powering the 60W bulb. I remember as a kid, my uncle made one to warm the bed.
In Japan they have low tables with a light bulb underneath. A blanket is sandwiched between two layers of a table top. You sit on the floor and cover your lower half with the blanket. Nice and warm.
Another wartime story about making use of lightbulbs. Prisoners in Scheveningen prison in The Netherlands, helped themselves to a smoke by collecting tobacco crumbs from their pockets, rolling this harvest into a cigarette using toilet paper, and then lighting it by wrapping a towel around the ceiling lightbulb in their cell untill it started to smolder. Later doctors rightly found that smoking is a health hazard 😮💨.
Love the dry humour! I dont yet have the kit for doing some of the stuff like this and have enough on sorting out my home but making a modern haybox in the form of a thermal bag for cooking having just finished a pile of draft snakes as Christmas gifts. All too on a "you cannot go wrong" budget 😂
My ancestors would preheat their beds using stone fruits or pebbles. Heat them in the fireplace in a corn popper. Heated they drop the items in an old sock or cloth bag and under the bed it went. About 15mins later crawl into a warm bed.
First I thougth you make an Original Dutch Stoof, lets See How hé is doing That. As a Dutch Woman. An then It went out in this Brillant idea, where you cann,t burn yourself. Awesome! Thank you. I cann,t make It myself but I admire the idea.
I use a 4 aluminium clad power resistors mounted on a thick aluminium plate as a fermentation heater. The temperature in the box is regulated using an ebay temp control module with sensor and a cheap wall wart psu. It would work just as well as a foot warmer I guess!
I had a conversation at work with a colleague today about the power being turned off and suggested to her that heating house bricks in the oven and making something on the same basic principle.
Not sure at what voltage a central heat and unit thermostat operates at in the UK but here in the states they are all 24 volt, perfect! so a 24 volt wall wart (power supply) would power it just fine. then wire the heating element as the load and set the T Stat where you want it, for me 85 degree F is more than plenty, then with the blanket over you and the stove it is regulated to that temp. OF course there is also the 19 volt laptop power supply, these I find in the thrift shop (charity shop if you will) for literarily 20 cents each. That may be perfect with out a TStat. GReat idea!! Thanks, good sir!
The Dutch "Stoof" is a small, metal lined, wooden box with holes at the top. As far as I know, a small amount of hot coals were placed inside. The stoof was used as a heated footstool, and stems from a time before central heating.
Well, the easiest and nicer way is to put a lightbulb of 60 watts inside such a case. Same heat and you have an indicator-light on it. And extra benefit: no power-supply needed that is wasting heat in the room. You can also use a 75 Watts lamp in those and they work quite nice but are mostly a bit overkill. But then; just unplug it and let the mass do its work. Actually it is quite easy to put a little light-dimmer in such a box so you can directly control the output (lower light = lower heat). We used to use those also for the little chicken and keeping the eggs warm untill they hatched.
Here in the Netherland I usually see Dutch stoves in the Charity shops . They are sold as a modern day golf umbrella stand . Next time I see one or more I'm going to buy .They are usually very cheap .
@@ThinkingandTinkering Thankyou for your motivation . Next day off work I'm going to the charity shops. The ones I've seen are maybe 30cm squared, usually metal lined . I will send you a picture once I buy .
I wonder if that slate heater element would work good in a sand battery configuration to give off a more constant heat while using little energy? Maybe for like a small room heater rather than a large room heater.
I was thinking that too, but my conclusion was that you'd need to have some thermal cut off circuits to regulate the temperature in the sand battery. I feel that using the limiting from the supply voltage just wouldn't keep the sand at a constant temperature as the heater would be constantly pumping heat into the sand. Whereas air convection would effectively limit the amount of heat supplied from the heater.
using little energy means you get little heat mate - it's not about the amount of heat which is fixed by the amount of energy you put in - but the way you use it
Heating the person and not the place. I've done that. In university I would point a heat lamp at my back while I worked to have the IR heat me up. Worked well to heat only me and not the entire building
Nice refresher of the tried and tested. With those kind of specifications you can practically run it from an old (90W-ish) laptop charger. The resistance would probably need to be a little lower, like 6-ish ohms drawing ~3.2A at ~19V, nothing what an extra coat of conductive ink couldn't fix.
I’ve tried burning vegetable oil in a tuna can to keep warm. Thankfully your carbon felt idea has helped with the wick department. Unfortunately there’s a smell & I’m an asthmatic too. I also notice that soot builds up around the wick which causes the flame to go off if I have too much oil in there for the wick.
use alcohol. 91% should work (or pure grain alcohol, like Everclear) They burn cleaner. If not, a candle is better inside upside down flower pots for thermal mass.
Oh man! You come up with the most amazing things. It does look simple enough, but still too complicated for me. I have no knowledge of the powersupply, so , I wouldn't have a clue what I was doing. I'd probably burn down the place. Still, love all your videos!
If you can build the first part of the heater, the power supply is the easiest part. All you have to do is look for a power cube that supplies 2 amps at 24 volts DC. There are lots for sale on the web and you can even get a small variable power supply like Rob's for not so much money.. You don't need a lab supply to drive it like Robs. It really is just a matter of throwing some money at it. Depending on how much money you want to throw at it you can get a basic 24 wall cube for about $15 CDN or a lab supply for about $70 CDN and UP. Good luck if you decide to give it a go. The project is one of his easiest
it's pretty easy mate - have a look at the chair seat cover we did - it's the same idea and Mi said a lot of sensible things - well worth looking at that
@@ThinkingandTinkering Thanks for all the answers! Will definitely look at the chair seat cover video. I need to have a feeling that I at least know what I'm doing (before I mess with electricity).
I really like the channel Robert because you are an open source location of information for the sharing of minds achieving a desired goal for the good of the masses. Using cheap and easy to get material for upcycling with a flare for aesthetics makes the point come across for a desire in using the made item that is easy on the eyes with function to boot. Why do you call copper foil tape, slug tape ??? Maybe British terminology passed down over the years ??? One other thing, please do not get cross with me as I am just saying. The "Dutch Oven" term used in usa is when the man and women are laying in bed and the guy covers the women with blanket and FARTS... I had to let you know fella as an inquisitive mind is a informative mind. Peace
information is always the prize mate lol - we call it slug tape because slugs don't like it - you put it found plant pots and the slugs won't cross it and eat your plants
Hi Robert, excellent video :) and I like the idea of carbon fibre as this will reduce the weight but could you advise what type, thickness etc carbon fibre you would use please? Thanks Robert, keep up the good work :)
If you put that concrete slab in your oven when you make your dinner at 6:00 pm and then put the slab into the Dutch oven you will have warm feet all evening .
I can see cutting up a pallet and using it instead of that furniture. it looks just like a piece cut out of a pallet. The pallet already has the air spaces built in on the top, the spaces between the boards. Just a thought.
A 60watt incandescent old fashioned light bulb will do the same job if all you want is a warm footstool... and many of us have a shed load of these because we thought they would be unobtainable. This was before LEDs superceded all those useless curly neon lamps that took ages to warm up - by the time you'd pee'd, they'd just be giving out enough light to see where you're aiming!
i wonder could u do a review on these diy terracotta clay pot tea light candle stoves that are all over utube are they any good? do they even work? and the science of them thanks
Old furniture is the main source of wood for small projects for me. I see so much old wood furniture on the curb and otherwise beautiful wood ends up in the landfill.
Great video! But it was a little sad to see that bit of late 50's - early 60's kitsch furniture die. That would have been right at home in a space-age bachelor pad.
For what it's worth, I was born in the 80s and style from the 40's-60s is my favourite. I have been wondering as of late why the appliances aren't brought back, especially the Frigidaire Flair line. Space-saving, easy to use and clean. With tiny homes becoming increasingly popular, the market is there! So is enjoyment of retro americana. We deserve the quality our grandparents had, and the affordability.
Sure you could get 26°C just by putting a cat in it. Of course, there'd be some drawbacks... Back in the good old days you could have put a lightbulb in it, with a baffle to keep the light out of your eyes. That might still work with a CFL, some of them get pretty warm.
I wager you could use the "Nano carbon heater" just under the holes, since it's only a bit of heat, and no danger to the wood case. And that's essentially what you have...
Wouldn't it be more effective putting the prepared stone in upside down? Then the rising heat would be stored in the stone (like a night storage heater).
You know how people joke about who they’d want with them if marooned on a desert island? I wonder how many of those lists include our Mr. Murray-Smith. Mine certainly does.
Hi Rob, had an idea for a video that seemed right up your alley! and not out of your scope with all the electronic test equipment you have laying around...how about a multi-stage Ionic Thrust powered rocket stove? with marketing buzzwords like that shoehorned in it'll sell out in no time!
Seems as good as a nice pair of warm socks... just a bit more work. It seems like all solutions for heating require an energy source, but if or when things become scarce... what then? I don't know if it is has potential, but what about a heat source based on whatever is used to make the hand warmers? Could the chemical reaction in those be designed so that they can be used again and again? To paraphrase your thought... they too would heat the person and not the house. Possible or not?
i guess something interesting could be done about the way you heat the back of somebody by blowing hot air from your mouth against the cloths. Something about compression in thight fibre, making strong heat from not so much... Maybe with a foot pump looking like your dutch stove ?
Now you got me thinking of a heated recliner chair, Computerfans. Blowing compressed air thru a restriction to make heat? Sounds like a Science Project. If you re-circulate the air it could get even hotter. Compressing air would be a heat pump moving heat to person at expense of the room.
@@mike289homebuilt5 Yes, but "at the expense" isn't it a problem? Why not otherwise compress air thrue the textile back of a rocking chair, using the movement ^^ Or the same pedal used for foot propelled sewing machine ^^ ?

1. The dynamo has too much friction, the more friction the more loss you've got. Would be better to use static magnets on the wheel and coils outside if you don't like a generator ;).
2. When you remove some of the spokes, you know when you fix these things, that you take the wheel out of the balance. So, a better way would to be cover with some lightweight element though some of the spokes.
3. Now everyone has a water :D, so it would not work for everyone. Robert is trying solutions which are most universal.
@@screen-protector I agree entirely .
Magnets work even better .
In Scandinavia the bike wheels are fitted with a magnet at intervals around the rim .
There are magnets mounted on the forks.
When the magnets pass it sends a current to light the bikes LED's
I guess it's all about what energy is making the wheel move.
Harnessing nature or using peddle power .
I always imagined what energy could be generated and stored, if every Gym's (such as 'Fit for Free)' training devices were hooked up to capture all that energy.

Another great vid 😀👍 We used to smelt aluminium and had three phase lathes plus all the power tools in woodwork when I was at school. All the kids do now is make things out of plastic with blunt tools or 3D print something. We’re a dying breed and a lot of them but not all will look to us when things get worse. 😎😀
Organize. You will be there when people realize they need you. True value.
The lesser tribes choose their zip code based on whistles and bells... the greater tribes choose their zip code based on the education their children will get.
You're giving off some serious "mad scientist" energy. I like it! 🙂
If you left the bottom drawer in, you could fill it with sand and heat that to store your heat. Maybe switch the drawers?
good idea
Keep up the good work on energy and heat ideas. Critical info this winter. Much more relevant this year.
cheers mate
I am a big fan of saving power. When a pot has come to the boil, I cover it with two old towels and set it aside to finish cooking in its residual heat. This method also helps to maintain the vitamin content. Straw lined boxes were used for the same purpose during WW2.
We use a single induction hob (in the summer) to heat a whistling kettle (so I don't forget!). We have a flask next to the kettle so once we have poured our cups, any left over goes in the flask to build up for at least a few more drinks. Now it's winter we have a kettle on the wood burner and it just happily sits there until it's boiling, then that water is used in the same way and left overs go in the flask. Free cups of tea all winter 🙂
I may offer some clarification. The Dutch Oven has a different meaning in the states. The Dutch Stove must be unique to places across the pond. I'm not familiar with it but I admire the repurposing. I don't understand the electrical part of it but I think I could build it.
Liked the vid.
this looks like a project you could gut a simple old coffee maker for,

I had the misfortune of spending a winter in a cottage with no central heating a friend lent us some one man tents to put over the beds was surprising how warm it got when shielded from the arctic blasts of air coming under the door and thru the "quaint" single glazed windows. Am contemplating making a space foil 4 poster bed might wake up thinking im the christmas turkey but will be warm 😀
That's great. My solar set up will work bootifully with that.
I’ve just remembered I have my mother’s antique brass bed warmer. It was decorative in her house, hung by the fireplace, but it’s an iron dish, like a large round casserole dish size, with a brass perforated hinged lid. You put embers in there. The thing has a long metal handle, and looked like a wooden piece fitted on the end to not burn your hands. This would then be carried around the bedrooms at bed time, and inserted between the sheets where you’d lie, to warm it all up before you climb in. Not to use too many embers I suppose, so you don’t shake a spark out into your bed and be on fire by 3am! But it was a thing they did, apparently.
If i remember about those bed warmers they used heated cherry pits or maybe even heated stones. No worries about a 3 am bed fire
@@sassafrasred6657 ah, that does make sense. Thank you! Always have to cast about wondering for somewhere to put my cherry stones; now I know! I suppose plum stones and similar would also do
@@sassafrasred6657 Crushed walnut shells in a flannel bag, place in microwave for a minute or two (depending on the microwave). Toss into the foot of the bed. Easy peasy.
I bought three bottle shaped bed/babywarmers at a garage sale this summer. Fill it with hot water. limit contact heat with a pair of old socks. So ol' skool.
These videos are just great. Thank you so much! With your no nonsense manner, and something that reminds me of my Dad. He had natural physical skill, could just put his hand out and catch something falling, effortlessly, yet without being dainty about it. Your a Natch! A ‘natural’. With lots of study or practice behind it, I’ll be bound 😉. I used to find the maths behind physics a real challenge a school, but somehow “got” the principles. But I’d have done ok in you class, I’d like to think. Practical and relevant and interesting
Great video. I do a few house clearance jobs and use expensive cabinets for firewood all the time. Stuff like that is only worth what folks are prepared to pay. Keep up the good work. Cheers. Rob
for sure mate - cheers
I sure wish you sold those cabinets in my area
resale would be better than burning, perhaps?
the old Dutch stoves had a teracota inner pot with a glazed inner side that was the test.
you placed glowing coals in the test that heated up the teracota pot and it gave off the heat
I think my grandmother had something like that. On a bigger scale it was in church where we went in my youth. Under your feet was a metal raster with embers underneath in the old days but I have never seen it work. I visited that church last year and that stoves were still there. I think when it needs to be they still can be used.
I am going to look out for them the next time I am in church - cheers mate
@@ThinkingandTinkering in my case it was a while ago... Maybe the same was done in many other countries... Probably. ....
When I was a kid in N.Ireland the churches were bloody freezing - you weren't there to be comfortable.
@@johne7100 : In the RC cathedral in the town where i lived, the pews only had a sturdy wooden hardwood 2x2 board across the back, at the height at which you would expect the top of the back of the pew to be, instead of a normal backrest on the pews like a person would normally expect to see on pews or even any chair at all.
When I asked about that situation, I was told that sitting in the pew was considered to be part of penance, and it was to encourage people to stay alert and to sit up straight at all times. Lol.
I imagine the cold church that you attended in Ireland, had some of the same sort of logic going on.
@@daphneraven6745 It had a lot to do with folk becoming atheists.
I am using a 240v 2.4Kw electric frypan as
a “foot stool” heater. I’ve taken the Bakelite feet off it. It is upside down on a cushion on the floor. I have powered it via a 240v to 24v transformer. So I’m supplying 1/10th volts, this results in 1/100th power.
2400w becomes 24w. The thermostat still works, so I can adjust the temperature to nice and warm. With warm feet I’m warm all over and my heating cost has dropped by 2 orders of magnitude
i see a tea light version could be very effective also.. love the vid! always learning something new..
Great suggestion!
Have lived in the Netherlands as a high school student. Knew elementary children had built similar stools at school to be used at home. The design was more like the ones seen in older paintings. It could hold a bowl of warm coals. In some Reformed churches there is a floor plate for the congregation who sits in the front pew. Hot water is circulated underneath and feels great during winter services.
Specifically targetted heating like this seems like a smart way to go. Get a little low-power heater and bundle up with a blanket or warm clothing and you can be comfortable with minimal additional cost.
It gets very cold where I live; today's low temperature is -37°C and I am very thankful for central heating.
12 volt electric blanket guts, harvested and glued to a flat stone -- includes dial to regulate the temperature in your little tent, in a car, closet in a squat, pickup truck shell...
nice
First mention of electric blankets in a while. Why not just use it?
@@bella-bee Freedom of movement around in the little space. Gotta be doing more than reading or working the laptop for hours and hours. And the sleeping bag is actually more comfortable when at rest anyway. But yeah, it would seem like being wrapped in a reliably warm blanket would be the ticket -- until that ride doesn't go anywhere even nearby.
I found someone who suggested heat pads, as used in vivarium, for your lizard tank or whatever! Got it on Amazon, I chose a 14w version so it wasn’t too big (about a ft square). Yes it plugs in the mains, no adaptor, transformer, so you need the power on in the first place, but it’s cheeeeeap and keeps me nice and warm at my desk. Cuddle it, footwarmer, mouse mat etc. I sat on mine at my computer. Mini electric blanket even. If a lizard can sleep in it I suppose I can, but I don’t know whether it’s truly safe. So do your own research. I gather the bigger ones don’t get hotter, just a bigger area getting as hot, if that makes sense. It feels as hot but over a larger area. Google vivarium heater.
An old war time alternative is to fit a standard 230v light bulb socket into the lid centre of a large empty tin (metal) container about 8" dia x 10" long. Punch 3/8" dia holes around the tin to allow heat to escape. Put a 60W light bulb in the lid socket with bulb inside the tin. Obviously care needs to be taken as it's 230v mains powering the 60W bulb. I remember as a kid, my uncle made one to warm the bed.
In Japan they have low tables with a light bulb underneath. A blanket is sandwiched between two layers of a table top. You sit on the floor and cover your lower half with the blanket. Nice and warm.
Another wartime story about making use of lightbulbs. Prisoners in Scheveningen prison in The Netherlands, helped themselves to a smoke by collecting tobacco crumbs from their pockets, rolling this harvest into a cigarette using toilet paper, and then lighting it by wrapping a towel around the ceiling lightbulb in their cell untill it started to smolder.
Later doctors rightly found that smoking is a health hazard 😮💨.
Very cool indeed, looks like a furniture piece that raises temp a couple of degrees.
That one is very nice, safe and can be used in many areas.
Good Job 👍
First time I saw that conductive paint. Pretty neat stuff!

We use our log stove to heat bricks, then wrap them in towels and put at the foot of a bed. Stays toasty all night!
Love the dry humour! I dont yet have the kit for doing some of the stuff like this and have enough on sorting out my home but making a modern haybox in the form of a thermal bag for cooking having just finished a pile of draft snakes as Christmas gifts. All too on a "you cannot go wrong" budget 😂
My ancestors would preheat their beds using stone fruits or pebbles. Heat them in the fireplace in a corn popper. Heated they drop the items in an old sock or cloth bag and under the bed it went. About 15mins later crawl into a warm bed.
First I thougth you make an Original Dutch Stoof, lets See How hé is doing That. As a Dutch Woman. An then It went out in this Brillant idea, where you cann,t burn yourself. Awesome! Thank you. I cann,t make It myself but I admire the idea.
I use a 4 aluminium clad power resistors mounted on a thick aluminium plate as a fermentation heater. The temperature in the box is regulated using an ebay temp control module with sensor and a cheap wall wart psu. It would work just as well as a foot warmer I guess!
it would
I had a conversation at work with a colleague today about the power being turned off and suggested to her that heating house bricks in the oven and making something on the same basic principle.
nice
Not sure at what voltage a central heat and unit thermostat operates at in the UK but here in the states they are all 24 volt, perfect! so a 24 volt wall wart (power supply) would power it just fine. then wire the heating element as the load and set the T Stat where you want it, for me 85 degree F is more than plenty, then with the blanket over you and the stove it is regulated to that temp. OF course there is also the 19 volt laptop power supply, these I find in the thrift shop (charity shop if you will) for literarily 20 cents each. That may be perfect with out a TStat. GReat idea!! Thanks, good sir!
The Dutch "Stoof" is a small, metal lined, wooden box with holes at the top. As far as I know, a small amount of hot coals were placed inside. The stoof was used as a heated footstool, and stems from a time before central heating.
Well, the easiest and nicer way is to put a lightbulb of 60 watts inside such a case.
Same heat and you have an indicator-light on it.
And extra benefit: no power-supply needed that is wasting heat in the room.
You can also use a 75 Watts lamp in those and they work quite nice but are mostly a bit overkill. But then; just unplug it and let the mass do its work.
Actually it is quite easy to put a little light-dimmer in such a box so you can directly control the output (lower light = lower heat).
We used to use those also for the little chicken and keeping the eggs warm untill they hatched.
nice suggestion mate - but quite literally anything will do
60 watts to keep yourself warm 👍 1500 watts to heat a small room
That's a really nice twist you added there! I can imagine you dozing off on the couch in your first trial run 😝
Don't know why but I love these vids!!
Here in the Netherland I usually see Dutch stoves in the Charity shops .
They are sold as a modern day golf umbrella stand .
Next time I see one or more I'm going to buy .They are usually very cheap .

Real innovative ideas, and clear instructions! Love it
Would love to see you heat the interior of your shop with wind power and thermal mass storage
I wonder if that slate heater element would work good in a sand battery configuration to give off a more constant heat while using little energy? Maybe for like a small room heater rather than a large room heater.
I was thinking that too, but my conclusion was that you'd need to have some thermal cut off circuits to regulate the temperature in the sand battery. I feel that using the limiting from the supply voltage just wouldn't keep the sand at a constant temperature as the heater would be constantly pumping heat into the sand. Whereas air convection would effectively limit the amount of heat supplied from the heater.
using little energy means you get little heat mate - it's not about the amount of heat which is fixed by the amount of energy you put in - but the way you use it
As usual. Brilliant video.
I could listen to you talk about sorting catshit all stinking day and be happy. I don't even own a bunch of tools or nothin' but this was enjoyable.
Reminded me of "hay box" cooking. Where you heat a pot to boiling point, and then put it into an insulated box to slow cook.
hay gives off heat, fermentation, in summer
yeah - I can see what you mean - good thought mate
With a Peltier module, you could build something to keep your feet warm, and a couple/few beers cold.
This is absolutely brilliant. Its useful and also looks really neat .....
Heating the person and not the place. I've done that. In university I would point a heat lamp at my back while I worked to have the IR heat me up. Worked well to heat only me and not the entire building
Nice refresher of the tried and tested. With those kind of specifications you can practically run it from an old (90W-ish) laptop charger. The resistance would probably need to be a little lower, like 6-ish ohms drawing ~3.2A at ~19V, nothing what an extra coat of conductive ink couldn't fix.
very true mate and cheers
Using cannon balls for a room heater was in Poland around 15 hundreds I believe
You are a real..."HOOT." Thanks for the idea.

I’ve tried burning vegetable oil in a tuna can to keep warm. Thankfully your carbon felt idea has helped with the wick department. Unfortunately there’s a smell & I’m an asthmatic too. I also notice that soot builds up around the wick which causes the flame to go off if I have too much oil in there for the wick.
use alcohol. 91% should work (or pure grain alcohol, like Everclear) They burn cleaner. If not, a candle is better inside upside down flower pots for thermal mass.
So now all we gotta do is paint the inside lining of a jacket, hook up some double A's in series 😁
I got socks with batteries to warm my feet from my husband last year!
Oh man! You come up with the most amazing things.
It does look simple enough, but still too complicated for me. I have no knowledge of the powersupply, so , I wouldn't have a clue what I was doing. I'd probably burn down the place.
Still, love all your videos!
If you can build the first part of the heater, the power supply is the easiest part. All you have to do is look for a power cube that supplies 2 amps at 24 volts DC. There are lots for sale on the web and you can even get a small variable power supply like Rob's for not so much money.. You don't need a lab supply to drive it like Robs. It really is just a matter of throwing some money at it. Depending on how much money you want to throw at it you can get a basic 24 wall cube for about $15 CDN or a lab supply for about $70 CDN and UP. Good luck if you decide to give it a go. The project is one of his easiest

If you put that concrete slab in your oven when you make your dinner at 6:00 pm and then put the slab into the Dutch oven you will have warm feet all evening .
I can see cutting up a pallet and using it instead of that furniture. it looks just like a piece cut out of a pallet. The pallet already has the air spaces built in on the top, the spaces between the boards. Just a thought.

A 60watt incandescent old fashioned light bulb will do the same job if all you want is a warm footstool... and many of us have a shed load of these because we thought they would be unobtainable. This was before LEDs superceded all those useless curly neon lamps that took ages to warm up - by the time you'd pee'd, they'd just be giving out enough light to see where you're aiming!
any heat source will do mate

Old furniture is the main source of wood for small projects for me. I see so much old wood furniture on the curb and otherwise beautiful wood ends up in the landfill.
Great video! But it was a little sad to see that bit of late 50's - early 60's kitsch furniture die. That would have been right at home in a space-age bachelor pad.
For what it's worth, I was born in the 80s and style from the 40's-60s is my favourite. I have been wondering as of late why the appliances aren't brought back, especially the Frigidaire Flair line. Space-saving, easy to use and clean. With tiny homes becoming increasingly popular, the market is there! So is enjoyment of retro americana. We deserve the quality our grandparents had, and the affordability.
Sure you could get 26°C just by putting a cat in it. Of course, there'd be some drawbacks...
Back in the good old days you could have put a lightbulb in it, with a baffle to keep the light out of your eyes. That might still work with a CFL, some of them get pretty warm.
Some led lights get hot 😠,

Seems as good as a nice pair of warm socks... just a bit more work. It seems like all solutions for heating require an energy source, but if or when things become scarce... what then?
I don't know if it is has potential, but what about a heat source based on whatever is used to make the hand warmers? Could the chemical reaction in those be designed so that they can be used again and again?
To paraphrase your thought... they too would heat the person and not the house.
Possible or not?
i guess something interesting could be done about the way you heat the back of somebody by blowing hot air from your mouth against the cloths. Something about compression in thight fibre, making strong heat from not so much... Maybe with a foot pump looking like your dutch stove ?
I am not sure what you mean mate - do a vid!
Now you got me thinking of a heated recliner chair, Computerfans. Blowing compressed air thru a restriction to make heat? Sounds like a Science Project. If you re-circulate the air it could get even hotter. Compressing air would be a heat pump moving heat to person at expense of the room.
