Brilliant idea! While we love our new Maldives (Xmas pressie to ourselves), it's a bit of a shocker how slow it heats and how much power it still uses. I'm a bit torn: we actually have a 12.5kVA solar system, so it's "free". What costs is the reduction in grid feedback for which we get paid. We're trying to get rid of gas use here complete, so it'd be a step backwards. However... 3 hours instead of having to remember in the morning to turn it on to use it in the evening... tempting. Very tempting.
Hi there, thanks for the video! How do you keep the temperature of the hottub at the right level? Is there an option for a thermostat in the portable gas boiler? I the video you suggest to use a timer that switches the system on for 2 or 3 times a day for half an hour. Is that enough to keep the water warm? Thanks for your help!
Hi mate great video. I'm currently setting up a system off grid and therefore using an lpg heating system for my tub. Ours is a rigid tub and I'm tapping into the pipes directly under the tub. My only slight query is where to put the pump? Is it on the pipe going to or from the heater? There's a pump internally on the tub and I was wondering if this would just suffice or whether I would need the additional one I've bought. In my head I keep thinking that the water will just be pushed up through the heater and out with the existing hot tub pump, but then I keep thinking I need one on the pipe going to the heater which presumably will push the water through the heater back to the tub?? I'm confused!
Quick question does having chlorine in the hot tub affect the pump and the heater unit? Would it corrode the internals? Good idea tho!! Might have a go.myself
I bought a 12L (3.2 GPM) tankless water heater to help speed up the heating of my 290 gallon (6 person) hot tub. I’m not sure which pump I should buy to pump water to the heater. I want a 110v pump that I can plug in to a socket (probably into a programmable electric timer, so I can time the pump to go on every 20 minutes as a work-around for the 20-minute timer shut-off most tankless water heaters have.) Since the purpose of running the tankless heater is to save time and money, it seems that a cheap pump would make sense, one that doesn’t consume a lot of electricity since it will be running a lot…and most likely at the same time as my hot tub’s own pump will be running. The 12L heater puts out a maximum of 3.2 GPM, (the intake’s suitable water pressure is: Min. 0.02MPa and Max.0.8MPa…I’m guessing that 0.8MPa is close to 3.2 GPM, but I haven’t been able to verify that) so it would seem that I should be looking for a pump that (lifts the water about 4-5 feet) and pumps no more than 3.2 GPM (or maybe even a pump that allows control over how fast the water is pumped in order to have more control over how hot the water gets on the first pass through the heater). It makes sense that it would be better to slow the water flow to the heater if that meant getting water as hot as you want it on the first pass, rather than waiting for the whole tub’s water content to pass through the heater multiple times to reach the desired temperature. Most of the ½ HP pumps I’m finding seem to pump around 6 GPM which seems to be too strong a water flow into the heater to get the water really hot on the first pass. I’ve been looking at some very small submersible pumps, even as small as fish tank pumps that are tiny and run at 40 watts or thereabouts. The numbers seem to add up as they say that they push 3 GPM, though I’m not too sure about the lift rate. The fact that they run under water seems to be nice in the sense that they must be quieter than pumps that sit outside on the floor. Some of these small submersible tanks have dials to control the strength of the water flow which seems like would be nice to easily adjust how fast the water goes into the heater thus controlling how hot the water is when it comes out. Any suggestions on which pump(s) I should look at for what I’m trying to do would be greatly appreciated! Thank you.
I would use a small 12v pump and a solar panel with battery to pump water thru gas water heater.the only power cost is the blower jets bubbles motor but you would only need to use that when you are in the hot tub(most power consumption is from running the element
Hi. I have a pump which with a timer and set it for 3 sessions of 20 mins. So I only have to manage that once an hour. The issue however is more with the pilot light going out with even the slightest breeze!
When I had my lazyspa palm springs I used to leave it set at 40c 24/7 so it was ready to use as and when from April through to October. Obviously it's expensive but I want it to be available at all times without having to wait for it to warm up. To recover the money that the tub costs to run I eat cheaper foods like beans on toast and eggs on toast from April to October. The savings on my shopping pay for the total hot tub running cost with some change left over. My overall health also improves due to the reduction in calories from eating healthier foods that are less expensive to buy. I pack my hot tub away in October otherwise I become abnormally thin.
Do you really need a pump? the unit has a filter pump built in so if you hooked up the additional heater inline /series on the out line from the unit, wouldn't that work? Just wondering b/c I plan to do something like that.
Tried it. You get E02 errors because the flow is restricted too much. It also depends on the type of lpg heater that you use. Many are setup for mains water pressure. ie, it takes mains water pressure to open the gas valve in the heater to turn the heater on. I used an 18l/min lpg gas heater. The pump in the lazy spa Egg is not powerful enough to switch the gas heater on. There are some 240v pond pumps that will have enough pressure and flow but who wants to put 240v pumps in their lazy spa's? I modified the gas valve in the lpg heater to operate on lower water pressure and used a separate 12volt water diaphragm type pump. The pump is rated at 17litres/min and is commonly used in campervans and caravans. I removed the flow sensor and ceramic heater from the Egg.
@@baldrickscunningplan6154 Yeah didn't work for me, not a problem with flow restriction but rather not enough PSI to fire it up. Just bought a 12v pump to recirculate the water.
Hi, do you think it would be possible to use the hot tub sand filter return pipe with split connectors to both prime the heater and return water to the hot tub?
So is your set up as follows… Water pipe from over the side of hot tub into pump Pump into the water in on boiler Water out into hot tub Or is it back in via pump. Bit more detail would be great really interested
Hi please could you tell me how you connect the pipes into the hot tub- are they plumbed into the egg or are they just submersed in the tub itself? Also does it make any difference as to what the pressure of the water from the pump entering the boiler is? Thanks, will do this, what a great idea!
Hello, great idea, i have a Layzspa and was thinking the same when i found this vid, i was thinking a pump wasn't needed as the camplux boiler says it will do 5L/min and no other equipment is neccesary, can you shed any light? is the boiler still working? Are you still happy, and any other helpful advice please.
Mr Meaner I’m assuming that is because it’s meant to be hooked up to some type of pressurized system, like hooking it into a hose outlet or the like which would push the water out and the 5l/min would be the most it could heat up. Since this is in a closed loop system it would need something to pump the water from the pool.
These units are designed to be hooked up to your cold water incoming main which flows through the boiler . Because this is rigged up to a tub the water is static .....so you need the pump to push it through the boiler
Sir thanks for this video, I'm trying to find a way to automate my hot tub, So moving to a different pump and heating unit is necessary. Can you provide a link or name and model number for that electric pump? Thank you sir.
Matt Snoby, here’s the link from Amazon, there may be other places that sell them too but it’ll give you something to go on Thank you for watching Eccotemp ECCL537EN CE-L5 Portable... www.amazon.co.uk/dp/B0058J54G8?ref=yo_pop_ma_swf
I’ve recently bought a garden pump similar to yours but the manufacturer says it will only work up to 35 degrees. Have you had any problems with your Karcher cutting out due to over heating ?
Hi, I'm trying to do the same with my Spa but when I read the pumps details I always see "35 degree max"...so how do you overpass that temp (ie 38-40 degrees celsius?)
List of parts needed to do an LPG conversion. All available from Ebay. 18 L/min 36kw tankless water heater. High pressure 12 volt DC Diaphragm Pump 17L/min. DC 12V 5Amp 220V Power Supply. Commonly used for LED Strip Lights. 12V Mini Power Songle Relay SPDT 5-Pins Digital Time Delay Relay Trigger Cycle Timer Switch Display Board LPG gas bottle and regulator. Same type used for garden heaters. 2 hose pipe connectors and jubilee clips and hose pipe. The timer relay and 12 volt relay are used to reset the boiler every 15 minutes to override the 20 minute internal timer in the boiler. The internal timer turns the boiler off after 20 minutes and you have to reset it manually without the timer module. This conversion is for the boiler to be mounted outdoors and the hose pipes are put into the Spa water. My Spa is inside a Summerhouse. The LPG heater is also inside the summerhouse. The Boiler has to be adapted and a flue pipe added to be run indoors. You will need some thin copper sheet and Car exhaust repair paste to fully enclose the burn chamber and a few screws so that all of the gases exit the flue. Never run these Boilers indoors as standard. They give off carbon monoxide. You must fully enclose the burn chamber. It is simple to do. There are open vents at the top of the burn chamber. These need to be blocked off with the copper sheet and sealed with the exhaust repair paste. Screws hold the copper sheet in place until the paste sets hard. I have mounted the 12v DC power supply inside the Bestway Egg and removed the electric heater. My pipe connections to the Diaphragm Pump are made inside the Egg so that there are no hoses in the Spa. Doing this enables you to use the Egg inbuilt control buttons to switch the heater on and off and also control the temperature of the Spa water. You can still run the Egg circulating Pump independent of the heater and you can also continue to use the timer controls to heat up whilst you are out. Just switch on and wait for it to heat up. It switches off when the desired temperature is reached. Switching on the bubbles turns off the gas heater. Mine takes 45 minutes to heat from 19 degrees C to 36 degrees C and costs approx £1.50 in gas.
@@peterdavies2922 You will need a 18litre heater if you want it to heat up quickly. Used our 18 litre heater yesterday. Water was 12 degrees C before heating. We have cold weather here in the UK atm. It took an hour and 20 minutes to heat to 40 degrees C.
ralphylad looking at my smart meter, running the hot tub cost £3 a day🤔 The gas cylinder lasts a month and costs £35 I now leave the filter running only and heat when we need it( approx 4 times a week) and I’m in for about £40 pcm
What is the noise like from the karcher pump? One thing I noted from the Palm Springs is that it has a fairly loud resonance, our neighbours complained
Tracy Stewart be sure to have a good quality strength core hose for drawing what will be warm water from the tub. Standard cold water garden hose will collapse
Matt The Cornish Dad Hi, thanks for watching. I only put chlorine in the tub, sometimes some Clearwater chemicals for foaming an shock. All this passes harmlessly through the units filter and heating system so I guess it’ll be ok through the unit 👍
Hello I literally love this idea, I have an intex 6 man 1000 litre inflatable spa. I am finding the running costs dear, can you tell me how you utilise the hose connections as surely one has the temperature sensor for the ambient temp of the pool, so if you remove the pool heater and filter pipes how does it regulate and monitor etc? I have a shed 6 feet away so I am thinking of installing the boiler in the shed and running long pipes to the spa, cant see why this wouldn't be okay? Such a great idea ty so much! Your reply would be very welcome!
rich saunders hi Keep the filter and running to ensure water clarity. You’ll have to keep an eye on things approaching your required temp. Then just pop the heater on to maintain 👍
@@tryityourself3870 Thankyou for your swift reply! SO I have ordered myself this, www.lismoreappliances.com.au/user_upload/images/s-l16001.jpg its the 12 litre version which is 3.4 GPM. My questions are if you would be able to assist is mainly now to do with the pump required to feed the heater from the spa pool. I have 240v where the heater and spa is situated so I can go 240v but I see a lot of people use 12v pumps off a battery, id rather avoid this. I see you bought the Karcher pump but not sure if that is overkill for what I need? Any advice again would be welcome, kind regards, richard
Janelle Fennec you’ll need a standard screw on hose fitting, the same as you’d screw onto your outside tap. (You might need and adapter if the size is different. As far as anything else just make sure you use hot water hoses.
Hey. I know this sounds dumb but would you only use this ad-hoc for when you wanted to use the tub? By this I mean you would have to switch it on when you want to use it and couldn’t just leave it like a normal hot tub?
Hello, thanks for watching Yes we tend to use this option only when we need the hot tub, the gas bottle whilst it lasts a while would soon run out if left on for days, also there is a tenancy for the pilot light on the water heater to go out with a slight breeze so it needs some monitoring. This isn't an issue really as you can take a hopt tub from cold to 40 degrees in a matter of only a couple of hours!
Correct me if I am wrong ( I probably am) but couldn't you just get a free, non-working hot tub on Craigslist and do the same thing? I'm trying to do this with a barrel type tub. Although I am interested in the Lazy Spa. Thanks.
Tim Miller well you could just have an old bathtub and do the same thing but you’d have to think about filtration and somehow Generating bubbles. Personally I’d find a second hand working model off of eBay. Chemical balance is very important if you want to maintain a healthy tub 👍
A great idea, Thanks... anyone think it would be ok to use a sand filter pump as the flow to the boiler unit. Just thinking when I used an intex sand filter pool pump, the water was always crystal clear.. Could also be beneficial in terms of reducing chemical intake into the boiler unit itself. I did also use chlorine etc for my old above ground pool and would do now for the lay z spa. Appreciate any thoughts on this, Thanks
I bet it will work well - I am counting on it, as I have one coming tomorrow from amz. I'll have to do some creative plumbing as I want to use it for 'diy water jets' in my intex inflatable. But I thinking working with pvc is great fun. VERY IMPORTANT if you use one, to insure you have an anti-entrapment intake. If you don't know what that is, go find out. Very important. Very. (Also easy, but you can figure it out.
@@FreshfrogmarketingUk hi, do you think there is a need for anti entrapment or additional filter if the water inlet to the heater is from the sand filter return to the hot tub?
Cant you use the pump on the hot tub and just put in two tees for the gas heater / shower that way you use all the function of the ht tub inc digital temp and air pump for the bubbles
Scarebusdriver I think Dave meant disconnect the heating element in the factory spa pump-heater blower(Most power is used in the element) and put a "T" on the inlet and outlet between the spa and factory spa pump-heater blower unit so the factory pump will direct water thru the gas water heater then back in the other"T"
I don't think this will work. I connected my outlet to a slightly reduced pipe size and e02 came straight on. The in/out sensitivity on the lay z spa egg isn't very tolerant.
@@philyoung1 did you ever resolve - I was looking at keeping water going through the Egg to use that pump but the size on the inlet and outlet look odd
Instead of having an additional pump, could you just not run a pipe from the egg? So the egg outlet goes to the shower and the shower goes to the hot tub. Using its own resources to an additional resource?
Im lookong to do something like this with my lay z Monaco 1400L. Takes more than a full day to warm up with the heater. Im looking for these shower units on amazon, is it right that they are 180 quid ;'(
@@tryityourself3870 Nice one mate, were in Derbyshire, just been in the hot tub with whole family gorgeous today. I have ordered a Eccotemp CE-L5 off wayfair for £142 seemed a reasonable price, i think its the same one you have. I already have a butane cylinder. Can you tell me how tall your cylinder is as i want to buy 1 of those trolleys but not sure if my cylinder will be too large, yours seems to only just fit. Also can you recommend a decent pump off amazon that will do, i only intend to use it for the hot tub, or is the Karcher GP 50 the best bet. www.amazon.co.uk/Karcher-Surface-Garden-Watering-Drainage/dp/B010Q66OQG/ref=pd_rhf_se_p_img_1?_encoding=UTF8&psc=1&refRID=S7RVYN4XDF8WRA8FMWKD Thanks for any help in advance, i want to get this setup ASAP being as were getting nice weather lol
There are lots of pump options. Go for one with a timer as the heater has a 20 minute cutoff. The Katcher is brilliant I use it to drain the tub as well. It’s expensive though. Just depends on what you want to spend. The bottle does just fit but no issues. Any standard cylinder you use for a BBQ or patio heater will be fine. Enjoy the good weather 👍
@@tryityourself3870 hi again mate. So i just got my karcher gp50 today. Do i need a high temp hose to go from tub to pump and then pump to ecotemp? Or is normal hose fine. Temps will be max 40c i guess.
Hudson Marine yes, you’ll need a hot temp pipe coming from the hot tub, I used a standard hose but in time it will collapse under suction. Going into the tub a standard hose is fine as the pressure will allow the hose to keep its shape 👍
I was really excited by your solution, only to learn that over here in Holland, the price of propane or butane per kWh (€0.20) is almost the same as that of electricity (€0.22). It's about 30 euros for 10.5kg of propane. How much do you pay for your butane?
@@MichaelFlatman Technically you are right, bus alas electricity in the practice of an inflatable spa is not 100% efficient: if you have a spa like mine outside, on an average Dutch spring day with a temp of 15C, the spa loses 0.5 degree per hour, while the heater heats up 2C per hour, so effectively it heats 1.5c per hour. So if you want to heat up from 28C to 38C, it takes about 10 hours to heat the tub. The solution above, if I understand correctly, can heat a tub far faster. So in the end, it might be cheaper after all. I still use electricity, but we have our spa in a little garden shed, that help against the heat loss.
@@pietermol8508 it will only heat faster if you input more power. Technically yes you are right, you can save some energy by letting the temp drop overnight and only heating to what you need for when you need it. (on demand heating in a way).. But this is a bit limited, you can probably only do 4c like this. A bit like how turning hot water off in your house can save energy
@@AppCarpetCleaning It is quite a noisy pump but all diaphragm pumps are. You will not be able to generate enough pressure from a centrifugal type pump unless you use a 240volt pump of 800w or higher. I only wanted to use 12volt for obvious safety reasons. You will not find a 12 volt centrifugal pump that will generate enough pressure to operate the gas valve in the boiler. They are not powerful enough. Even the brushless ones are lacking enough power.
@@baldrickscunningplan6154 thank you. I’ve seen a number of different pumps used for different reasons. Still unsure which one will do the whole job that I want it to do.
Hi, can I ask, do you get bits of dirt coming out of the boiler from the hose after being heated? My friend has this setup and he said he gets small black bits coming out of it.
Hi, thanks for taking the time to comment. I’ve not experienced this myself or heard of anyone with a similar setup having the same experience. With water from the hot tub passing through the boiler it may be that some deposits have clung to the system internally. I’d look at flushing it with a clean water supply such as garden tap and see if that helps.
I had the same thing when i first filled up my hot tub. It was nothing to do with the boiler. City Council had been doing some water pipe repairs approx half a mile away. Sediment in the pipes gets disturbed and finds its way through everyones pipes until it is flushed clear. Never had any contaminants come out of the boiler.
It depends on the heater, check it's manual if it can handle both propane and butane, and if these require different add-ons, such as pressure regulators. Note that butane doesn't work well during cold temperatures, as the gas becomes all liquid and no longer expands into gas.
@@tryityourself3870 Actually, the higher the temperature difference between the spa and the outside air, the greater the flow of heat from the spa to the environment. It's better to let it cool off and heat it up when needed, especially since your system seems to be able to do it quite fast, compared to electric heating. It's a matter of finding the best balance between savings and heat-up time.
Can you send me the search terms for the stand? I’m getting a different one but I’m not finding any joy finding a stand. It’s probably dead simple.... I’m also dead simple lol

Hi, i have more or less the exact setup as you, do this sound right. For me i have to have the water on more or less as low as it can go and the heat on full. This for me gives a steady trickle of scalding water almost (too hot to touvh).

@@GoogleGoogle-ef5pw I have the same Boiler but mine is rated at 18l 36kw. Probably marketing BS. You will need a 37mbar LPG gas regulator for that Boiler. They have a 3 volt solenoid that opens the gas valve. If you go over the top with the regulator. The increased gas pressure stops the valve from opening. Its not a very strong solenoid. I modified my boiler by enclosing the burn chamber with copper sheet and car exhaust repair paste. It can now be used indoors. It will work fine with the FL40 pump. I have been experimenting with modifying the gas valve to run on a lower pressure pump. I have got it working on a small 24v DC circulation pump but i can only use the summer setting on the boiler. The winter setting opens a second burner but it causes the overtemp failsafe to cut off the boiler. I don't get any issues with the FL40 pump other than the noise. If you can mount the pump a bit further away. The noise won't be so much of an issue. Don't forget to add a small cooling fan next to the pump to keep it cool.
RS-Mike these units are designed to be used outside in well ventilated areas. The instructions are very clear .A canopy presents no ventilation restrictions. Also note once heated the unit is off so no chance of exposure to harmful gasses when the tub is in use. I’d recommend this to anyone. Massive savings to be had in heating your hot tub.

It also depends on the type of lpg heater that you use. Many are setup for mains water pressure. ie, it takes mains water pressure to open the gas valve in the heater to turn the heater on. I used an 18l/min lpg gas heater. The pump in the lazy spa Egg is not powerful enough to switch the gas heater on.
There are some 240v pond pumps that will have enough pressure and flow but who wants to put 240v pumps in their lazy spa's?
I modified the gas valve in the lpg heater to operate on lower water pressure and used a separate 12volt water diaphragm type pump. The pump is rated at 17litres/min and is commonly used in campervans and caravans.
I removed the flow sensor and ceramic heater from the Egg.
@@baldrickscunningplan6154 Yeah didn't work for me, not a problem with flow restriction but rather not enough PSI to fire it up. Just bought a 12v pump to recirculate the water.
Hi, do you think it would be possible to use the hot tub sand filter return pipe with split connectors to both prime the heater and return water to the hot tub?
So is your set up as follows…
Water pipe from over the side of hot tub into pump
Pump into the water in on boiler
Water out into hot tub
Or is it back in via pump. Bit more detail would be great really interested
Do u no haw to bypass the 20minit safety cut off
Hi please could you tell me how you connect the pipes into the hot tub- are they plumbed into the egg or are they just submersed in the tub itself? Also does it make any difference as to what the pressure of the water from the pump entering the boiler is? Thanks, will do this, what a great idea!
hello, they are just left freely into the hot tub. no plumbing required!
Hello, great idea, i have a Layzspa and was thinking the same when i found this vid, i was thinking a pump wasn't needed as the camplux boiler says it will do 5L/min and no other equipment is neccesary, can you shed any light? is the boiler still working? Are you still happy, and any other helpful advice please.
Mr Meaner I’m assuming that is because it’s meant to be hooked up to some type of pressurized system, like hooking it into a hose outlet or the like which would push the water out and the 5l/min would be the most it could heat up. Since this is in a closed loop system it would need something to pump the water from the pool.
These units are designed to be hooked up to your cold water incoming main which flows through the boiler . Because this is rigged up to a tub the water is static .....so you need the pump to push it through the boiler
Sir thanks for this video, I'm trying to find a way to automate my hot tub, So moving to a different pump and heating unit is necessary. Can you provide a link or name and model number for that electric pump? Thank you sir.

Just crack yours open wire relays across the switches boom 💥
I’ve recently bought a garden pump similar to yours but the manufacturer says it will only work up to 35 degrees. Have you had any problems with your Karcher cutting out due to over heating ?
I have the same concern... have you had problems on that @jamesgray4227?
Hi, I'm trying to do the same with my Spa but when I read the pumps details I always see "35 degree max"...so how do you overpass that temp (ie 38-40 degrees celsius?)
List of parts needed to do an LPG conversion. All available from Ebay.
18 L/min 36kw tankless water heater.
High pressure 12 volt DC Diaphragm Pump 17L/min.
DC 12V 5Amp 220V Power Supply. Commonly used for LED Strip Lights.
12V Mini Power Songle Relay SPDT 5-Pins
Digital Time Delay Relay Trigger Cycle Timer Switch Display Board
LPG gas bottle and regulator. Same type used for garden heaters.
2 hose pipe connectors and jubilee clips and hose pipe.
The timer relay and 12 volt relay are used to reset the boiler every 15 minutes to override the 20 minute internal timer in the boiler. The internal timer turns the boiler off after 20 minutes and you have to reset it manually without the timer module.
This conversion is for the boiler to be mounted outdoors and the hose pipes are put into the Spa water.
My Spa is inside a Summerhouse. The LPG heater is also inside the summerhouse. The Boiler has to be adapted and a flue pipe added to be run indoors. You will need some thin copper sheet and Car exhaust repair paste to fully enclose the burn chamber and a few screws so that all of the gases exit the flue. Never run these Boilers indoors as standard. They give off carbon monoxide. You must fully enclose the burn chamber. It is simple to do. There are open vents at the top of the burn chamber. These need to be blocked off with the copper sheet and sealed with the exhaust repair paste. Screws hold the copper sheet in place until the paste sets hard.
I have mounted the 12v DC power supply inside the Bestway Egg and removed the electric heater. My pipe connections to the Diaphragm Pump are made inside the Egg so that there are no hoses in the Spa.
Doing this enables you to use the Egg inbuilt control buttons to switch the heater on and off and also control the temperature of the Spa water. You can still run the Egg circulating Pump independent of the heater and you can also continue to use the timer controls to heat up whilst you are out.
Just switch on and wait for it to heat up. It switches off when the desired temperature is reached.
Switching on the bubbles turns off the gas heater.
Mine takes 45 minutes to heat from 19 degrees C to 36 degrees C and costs approx £1.50 in gas.
Does it really need an 18l heater - i think the one on the video is either 5l or 10l?
@@peterdavies2922 You will need a 18litre heater if you want it to heat up quickly. Used our 18 litre heater yesterday. Water was 12 degrees C before heating. We have cold weather here in the UK atm. It took an hour and 20 minutes to heat to 40 degrees C.
Ill have a look at my specs but it only takes a couple of hours
The High pressure 12 volt DC Diaphragm Pump 17L/min, do these work well? I'm struggling to find a decent pump that wont bust the water heater
@@jasongourley6105 They work very well. Enough pressure to run the boiler and they are self priming.

Wow that’s awesome!!! What was the cost difference to run this way after the initial outlay of pump and hot horse shower?
ralphylad looking at my smart meter, running the hot tub cost £3 a day🤔
The gas cylinder lasts a month and costs £35
I now leave the filter running only and heat when we need it( approx 4 times a week) and I’m in for about £40 pcm
What is the noise like from the karcher pump? One thing I noted from the Palm Springs is that it has a fairly loud resonance, our neighbours complained
@@ralphylad did you clean the filter?
Thanks a lot we had both delivered today just got to do a bit of shopping for hoses adapters and will be ready to go tomorrow

Hi, thanks for watching. I only put chlorine in the tub, sometimes some Clearwater chemicals for foaming an shock. All this passes harmlessly through the units filter and heating system so I guess it’ll be ok through the unit 👍

Could you let me know I bought a karcher bp7 would that work even though it can work up to 60 bar thankyou . Kind regards ken
I think that’ll be more than sufficient. I did run it off a small DC pump at one point and it was fine
Hello I literally love this idea, I have an intex 6 man 1000 litre inflatable spa. I am finding the running costs dear, can you tell me how you utilise the hose connections as surely one has the temperature sensor for the ambient temp of the pool, so if you remove the pool heater and filter pipes how does it regulate and monitor etc?
I have a shed 6 feet away so I am thinking of installing the boiler in the shed and running long pipes to the spa, cant see why this wouldn't be okay? Such a great idea ty so much! Your reply would be very welcome!
rich saunders hi
Keep the filter and running to ensure water clarity. You’ll have to keep an eye on things approaching your required temp. Then just pop the heater on to maintain 👍
@@tryityourself3870 Thankyou for your swift reply!
SO I have ordered myself this, www.lismoreappliances.com.au/user_upload/images/s-l16001.jpg its the 12 litre version which is 3.4 GPM.
My questions are if you would be able to assist is mainly now to do with the pump required to feed the heater from the spa pool. I have 240v where the heater and spa is situated so I can go 240v but I see a lot of people use 12v pumps off a battery, id rather avoid this. I see you bought the Karcher pump but not sure if that is overkill for what I need? Any advice again would be welcome, kind regards, richard
Did you calculate the real sonsumtion of LPG?
What adaptor did you use connect the pump to the tub? Likewise anything special to connect pump to heater?
Janelle Fennec you’ll need a standard screw on hose fitting, the same as you’d screw onto your outside tap. (You might need and adapter if the size is different.
As far as anything else just make sure you use hot water hoses.
Scarebusdriver thank you!
Always start with warm water at a minimum. I do half full of warm then start boiling potss of water until it's full
What do you mean... use the lazy spa first?
We fill ours from the washing machine hot water spigot
Hey. I know this sounds dumb but would you only use this ad-hoc for when you wanted to use the tub? By this I mean you would have to switch it on when you want to use it and couldn’t just leave it like a normal hot tub?
Hello, thanks for watching
Yes we tend to use this option only when we need the hot tub, the gas bottle whilst it lasts a while would soon run out if left on for days, also there is a tenancy for the pilot light on the water heater to go out with a slight breeze so it needs some monitoring.
This isn't an issue really as you can take a hopt tub from cold to 40 degrees in a matter of only a couple of hours!
Have we got an update on this? How many others have used this system? Is it cost effective? Any ideas on parts? Thanks
I made my own intention--very similar--$60/month vs $180 for electric that comes with the spa.
We are in a race Dave 😂😂
Correct me if I am wrong ( I probably am) but couldn't you just get a free, non-working hot tub on Craigslist and do the same thing? I'm trying to do this with a barrel type tub. Although I am interested in the Lazy Spa. Thanks.
Tim Miller well you could just have an old bathtub and do the same thing but you’d have to think about filtration and somehow Generating bubbles.
Personally I’d find a second hand working model off of eBay. Chemical balance is very important if you want to maintain a healthy tub 👍
A great idea, Thanks... anyone think it would be ok to use a sand filter pump as the flow to the boiler unit. Just thinking when I used an intex sand filter pool pump, the water was always crystal clear.. Could also be beneficial in terms of reducing chemical intake into the boiler unit itself.
I did also use chlorine etc for my old above ground pool and would do now for the lay z spa. Appreciate any thoughts on this, Thanks
I bet it will work well - I am counting on it, as I have one coming tomorrow from amz. I'll have to do some creative plumbing as I want to use it for 'diy water jets' in my intex inflatable. But I thinking working with pvc is great fun. VERY IMPORTANT if you use one, to insure you have an anti-entrapment intake. If you don't know what that is, go find out. Very important. Very.

That's the cost of the lazy spa system
Cant you use the pump on the hot tub and just put in two tees for the gas heater / shower that way you use all the function of the ht tub inc digital temp and air pump for the bubbles
dave cox I’m not sure what you mean?, it’s not possible on this model to run the heater and bubbles at the same time as only a 13amp plug.
Scarebusdriver I think Dave meant disconnect the heating element in the factory spa pump-heater blower(Most power is used in the element) and put a "T" on the inlet and outlet between the spa and factory spa pump-heater blower unit so the factory pump will direct water thru the gas water heater then back in the other"T"
Seems logical to me. Maybe he has separation anxiety with the decommissioned equipment.
I don't think this will work. I connected my outlet to a slightly reduced pipe size and e02 came straight on. The in/out sensitivity on the lay z spa egg isn't very tolerant.
@@philyoung1 did you ever resolve - I was looking at keeping water going through the Egg to use that pump but the size on the inlet and outlet look odd
Hi, are the eccotemp water heaters propane . Or does it matter.
Instead of having an additional pump, could you just not run a pipe from the egg? So the egg outlet goes to the shower and the shower goes to the hot tub. Using its own resources to an additional resource?
Some spa pumps might have problems with pumping the water to higher levels, so you need to keep the heater at ground level.
Im lookong to do something like this with my lay z Monaco 1400L. Takes more than a full day to warm up with the heater. Im looking for these shower units on amazon, is it right that they are 180 quid ;'(

Thanks for any help in advance, i want to get this setup ASAP being as were getting nice weather lol
There are lots of pump options. Go for one with a timer as the heater has a 20 minute cutoff.
The Katcher is brilliant I use it to drain the tub as well. It’s expensive though.
Just depends on what you want to spend.
The bottle does just fit but no issues. Any standard cylinder you use for a BBQ or patio heater will be fine.
Enjoy the good weather 👍
@@tryityourself3870 hi again mate. So i just got my karcher gp50 today. Do i need a high temp hose to go from tub to pump and then pump to ecotemp? Or is normal hose fine. Temps will be max 40c i guess.
Hudson Marine yes, you’ll need a hot temp pipe coming from the hot tub, I used a standard hose but in time it will collapse under suction.
Going into the tub a standard hose is fine as the pressure will allow the hose to keep its shape 👍
Does the heater have a 20 min timer ? I have the same and it cuts out after 20 mins.
Gareth Phillips yes, just use a pump that has a 20 minute timer, and set 3 an hour 👍
I was really excited by your solution, only to learn that over here in Holland, the price of propane or butane per kWh (€0.20) is almost the same as that of electricity (€0.22). It's about 30 euros for 10.5kg of propane. How much do you pay for your butane?
Yes, and what you have to remember the propane heater is probably around 70-80% efficient.. electricity is always 100% efficient.
@@MichaelFlatman Technically you are right, bus alas electricity in the practice of an inflatable spa is not 100% efficient: if you have a spa like mine outside, on an average Dutch spring day with a temp of 15C, the spa loses 0.5 degree per hour, while the heater heats up 2C per hour, so effectively it heats 1.5c per hour. So if you want to heat up from 28C to 38C, it takes about 10 hours to heat the tub. The solution above, if I understand correctly, can heat a tub far faster. So in the end, it might be cheaper after all. I still use electricity, but we have our spa in a little garden shed, that help against the heat loss.
@@pietermol8508 it will only heat faster if you input more power.
Technically yes you are right, you can save some energy by letting the temp drop overnight and only heating to what you need for when you need it. (on demand heating in a way).. But this is a bit limited, you can probably only do 4c like this.
A bit like how turning hot water off in your house can save energy

@@baldrickscunningplan6154 how noisy is this one please?
@@AppCarpetCleaning It is quite a noisy pump but all diaphragm pumps are. You will not be able to generate enough pressure from a centrifugal type pump unless you use a 240volt pump of 800w or higher. I only wanted to use 12volt for obvious safety reasons. You will not find a 12 volt centrifugal pump that will generate enough pressure to operate the gas valve in the boiler. They are not powerful enough. Even the brushless ones are lacking enough power.
@@baldrickscunningplan6154 thank you. I’ve seen a number of different pumps used for different reasons. Still unsure which one will do the whole job that I want it to do.
Hi, can I ask, do you get bits of dirt coming out of the boiler from the hose after being heated? My friend has this setup and he said he gets small black bits coming out of it.
Hi, thanks for taking the time to comment.
I’ve not experienced this myself or heard of anyone with a similar setup having the same experience.
With water from the hot tub passing through the boiler it may be that some deposits have clung to the system internally.
I’d look at flushing it with a clean water supply such as garden tap and see if that helps.
I had the same thing when i first filled up my hot tub. It was nothing to do with the boiler. City Council had been doing some water pipe repairs approx half a mile away. Sediment in the pipes gets disturbed and finds its way through everyones pipes until it is flushed clear. Never had any contaminants come out of the boiler.
You said you used butane gas I thought these only took propane would I be able to use butane as have a spare butane I used for bbq
It depends on the heater, check it's manual if it can handle both propane and butane, and if these require different add-ons, such as pressure regulators. Note that butane doesn't work well during cold temperatures, as the gas becomes all liquid and no longer expands into gas.
How long did your gas bottle last in the end?
Tracy Stewart about 6 weeks using 3-4 times a week. The trick is to use it more so the temperature drop is less thus using less energy
@@tryityourself3870 Actually, the higher the temperature difference between the spa and the outside air, the greater the flow of heat from the spa to the environment. It's better to let it cool off and heat it up when needed, especially since your system seems to be able to do it quite fast, compared to electric heating. It's a matter of finding the best balance between savings and heat-up time.
DutchAlps it depends on how much you use it. 3 or more times a week it’s more efficient to keep it running

Hi, i have more or less the exact setup as you, do this sound right. For me i have to have the water on more or less as low as it can go and the heat on full. This for me gives a steady trickle of scalding water almost (too hot to touvh).

@@GoogleGoogle-ef5pw I have the same Boiler but mine is rated at 18l 36kw. Probably marketing BS. You will need a 37mbar LPG gas regulator for that Boiler. They have a 3 volt solenoid that opens the gas valve. If you go over the top with the regulator. The increased gas pressure stops the valve from opening. Its not a very strong solenoid. I modified my boiler by enclosing the burn chamber with copper sheet and car exhaust repair paste. It can now be used indoors. It will work fine with the FL40 pump. I have been experimenting with modifying the gas valve to run on a lower pressure pump. I have got it working on a small 24v DC circulation pump but i can only use the summer setting on the boiler. The winter setting opens a second burner but it causes the overtemp failsafe to cut off the boiler.
I don't get any issues with the FL40 pump other than the noise. If you can mount the pump a bit further away. The noise won't be so much of an issue. Don't forget to add a small cooling fan next to the pump to keep it cool.

Good idea but also a way to get carbon monoxide poisoning. Move it away from your gazebo
RS-Mike these units are designed to be used outside in well ventilated areas. The instructions are very clear .A canopy presents no ventilation restrictions. Also note once heated the unit is off so no chance of exposure to harmful gasses when the tub is in use.
