Please please leave the music out mate, it's difficult concentrating on the important information you're saying, really appreciate the video tho, keep up the good work. Thanks.

I agree, the music distracts and adds nothing for me.
Having moved house several times, I found that the best thing (besides energy savings) about weather compensation and room optimization is that you don't notice it - that is until you move on to a new house with conventional on-off controls and realize immediately how very poor these controls are at maintaining a stable temperature! Since you can save money and be much more comfortable at the same time, I really don't understand why these systems are not completely standard already. I think unfortunately that's largely due to ignorance and lack of knowledge in the heating sector - many of these systems are not difficult to install and use - so it's great to see that you are spreading the word with your blog.
Informative presentation giving easy to understand explanation of various control methods to achieve max bang for buck from your heating system. Adam has assured me that Bruce Willis will endorsing Heat Geek’s excellent advice by swinging by the stage on a Tarzan rope. Keep up the good work, love the informal, concise but fun approach to the available technology driven options.
This whole channel is so good, technically, and so interesting. Thanks.
So kind! thanks🙌🙌
What a surprise! I didn't expect such a thorough explanation, it really influenced my purchase decision (went for TADO). Kudos for the attention given to the audio and video production: compared to other specialised channel it's been a + 👍🏼
Thanks Andrea!!!
@Andrea Mazzotta May I ask why you went with Tado over hive and nest?
A great explanation. I dread explaining this to customers. When you explain that you have range rated the boiler and then start to explain open therm controls and the modulation of the boiler. You see the vacant stare looking straight through you and you know you have lost them. I can point them to this video now and they can watch it over and over!!

After a house fire I had the opportunity to replumb my house. I researched "load compensation" and got a system (Evohome/Intergas) which does it. Honestly the best decision I ever made. Plumbers will tell you about efficiency but load compensation makes your place more COMFORTABLE. In other places I used to fiddle with the thermostat every week but no more. Load compensation just makes your home more comfortable by maintaining the right temperature and my boiler just hums instead of making horrid noises. I started as a stupid "I need a 50kw boiler" customer. Now I've educated myself through these videos I see how stupid I was. I never use more than 25kw to heat my home and even in those -2 temperatures last week it used 15kw most of the time, and in the Autumn it is more like 7 kw.
Guess that's the difference with Intergas boilers, seems many conventional combi boilers need to have 35 kW capability to provide 'instant' hot water - when modulation controls are fitted for room heating presumably only a fraction of the boiler's max power output is utilised.
Hi Robert. Which boiler & heating controls do you have please? I need a new boiler so this is my time to upgrade
@@1dozmos I have an Intergas boiler and I use Honeywell evohome as a controller
I've got a Vaillant Ecotech Plus 630, VRC700f controller and external weather sensor, VR920 gateway, VR50 Ambisense TRVs and VR51 temp sensors in most rooms. Expensive - Yes. Efficient - Probably Saving money - No idea Comfortable - Most definitely!!
A true 'fit and forget' setup that allows separate temperature control for the rooms occupied by my elderly MIL and lower temps elsewhere.
Loving the new set Adam! Your production value is really taking off!
Cheers Harry!
Well presented mate, miles ahead of other heating engineer brethren.
We have a Worcester Bosch Greenstar 38CDi Classic ErP boiler, and currently a Hive controller, though I understand now that was far from the best option (both installed by Scottish Gas 4-5 years ago). We have a 1990 4-bed bungalow, so currently expensive to heat due to large footprint and poor insulation. I'd be interested to hear about better smart thermostat options, especially one with room/zone controls (as I tend to stay in 1 room for most of each workday until the evening). I was initially attracted to the Tado solution, but am put off by them dropping modulation control from the wireless kit.
Clearing up confusion with a thoughtfully produced video. I could direct one my customers here for a nice overview & comprehensive explanation that is talking to end users & not at them.
Equally I could direct a fellow heating installer here that wants a nice overview, loving the summary of benefits of lower temps & wear & tear.
I have been taling about these benefits for over a decade, but could never round it up in such a clean & concise manner.
Thanks peter!

Hi Pal,
Like others I'm about to invest in a better heating controller, thanks for this informative video.
We have a Baxi Platinum 28 ERP which I understand to be a modulating boiler, we live in a 3 bed semi with 6 standard rads with TRVs and a towel radiator.
What solution would you suggest that would achieve per room controls (we work from home) whilst maintaining efficiency.
I'm unsure if modulating control module or electronic TRVs or a combination of both would be best.
Cheers in advance!
Another excellent video, well done. Funny you should say that about Evohome... I found my own at home asking for high temperatures more often than I thought it should so I limited the flow temp to 50°c and it works a lot better.
Thanks for another great video. We love our tado system easy to install and great at keeping our different zones how we like it and saved us money on gas bill but had heating on a lot more than the year before
Try setting the rooms to more similar temperatures. Watch our video called 'should I zone my boiler'
Hi Adam, great video! I've been told my Valiant Ecotecplus combiner's boiler is on its last legs so am considering replacing it. If I do, I will take the opportunity to upgrade to a smart thermostat. My 50m2 one bedroom flat (victorian conversion) is reasonably warm (when the boiler works!) in the 'living areas', but my bedroom is in an extension on the north of the building with only one radiator. I guess when they built the extension in the 60s they didn't really put much insulation in the roof above it either... gets pretty nippy! As a result I am also considering getting smart radiator valves to make the bedroom radiator work a bit harder... Am I thinking too big? If not, which (not crazy expensive) boiler and smart system would you recommend I go for??? Many thanks in advance for any further pointers!
At last someone who thinks like I do, I have been fitting Vaillant or Glow worm outside weather comp systems for 11 years now, from their 1st hard wired outside sensor to the Glow worm Systempro controller, what I really like is that it was the only system control package that allowed 3 zone wireless heating and a wireless outside sensor making the install simple and compliant with Energy Efficiency regs, its been brilliant gear and I have had really good help from their tech team.
At home I run underfloor heating with no blending pump downstairs as one zone and upstairs I have low temp rads with fans below that run on the same water temp as the underfloor heating in that second zone, the controls are Systempro3, wireless outside sensor, and two wireless Climapro2 room stats. I do use an unvented solar cylinder but both coils are connected to the boiler for super fast reheat times, in fact the high performance shower can not depleted the hot water store as it recovers in hot water priority faster than can be used, I am saving over £300 a year, plus its on from October until May. keep up the good information on here, its great.

Thank you for such an informative video. I'm about to have my old, broken boiler changed to a Worcester 4000 30kw in my Victorian semi ( 2 bedroom, 1 bathroom), before either selling the property as a renovation project, or having it renovated it and then selling it. The plumber who seems like the likely choice for the job has quoted for the inclusion of an ESI wireless controller (model not specified). I don't know if this is a modulating controller. My quick research appears to show that the boiler is modulating, though I couldn't see what language it uses. I very much like what you have said regarding advanced weather compensating controllers, though I am a bit tight on budget. Could you advise as to whether I should go with the ESI controller or possibly recommend any other control systems that might best suit?
Hello Adam,
I am having a bit of a difficulty in choosing as smart thermostat for my house in Toronto Canada. It is a 3 story red brick with cast iron style radiators in most rooms. My boiler model is a Slant/Fin VSPH120XEP Natural gas boiler. I am also looking to install thermostatic valves to regular the irregular heat distribution on each of the floors so I am not sure if that might affect the type of smart thermostat I get. What would you suggest as a good smart thermostat. (I already use a lot of alexa based devices for lighting, security and automation)
Thanks a bunch for your informative video as well.
Just for some feedback. Did anyone watch the bloopers at the end? Should I leave these in? My wife though I left it in by accident 🤣
Yeah, keep those in.
@@thomassmart8403 thanks mate
Bloopers are always good. Agree to tur down the music a little though. Distracting.
I enjoyed the bloopers! Might be helpful to introduce them with a "Bloopers" sign.
Very Very Very helpful video. I beg you, please don't use that background music, I had to rewind multiple times just to listen what you were saying.
Solar gain makes an enormous difference to the temperature inside my house. Cloud free nights can produce really low temperatures, so the air temperature input suggests turning up the heating, but the following sunny day creates an over heated house for a slow reacting heat source such as storage heaters or heat pumps.. Not sure how this solar gain can be taken into account, but it does need to be compensated for in my house and surely many others. Haven't seen any mention of this problem, but still researching. Any suggestions?
You suit load comp more. We have a whole article on this..
www.heatgeek.com/weather-compensation-or-load-compensation
It depends whether the boiler supports opentherm comm protocol. If the boiler does not, even Nest will apply on/off modulation. Also, the system dynamics can be controlled perfectly even with on/off modulation to avoid oscillations
It goes in to compatibility in the video and it doesn't have to support opentherm. Not sure what you mean by oscillations if you mean over shoot and undershorts sure.. but the flow temperature still over and undershoots so misses the point..
Great video, thanks for all the info. You explained everything really well!
IMO I like the background music, but agree that it could be a bit quieter.
I think it would be really helpful to have a few more visuals, eg. a written list of all the benefits while youre saying them.
Thanks again, will definitely check out your website!
Thanks!! And thanks for the feedback. Lively name by the way.
Just watched your video and love the message here. I am so new to this and want to get the most efficient set up that I can. So, I have a Baxi 600 being installed next Wednesday, with a google nest smart thermometer (3rd gen). My aim here is to have maximum efficiency, however I cannot purchase the temperature sensors for google nest so confused how the temperature in the house can be regulated properly via the bus control (I really don’t know what I’m talking about!)? Is this a good set up to go with?
Nest is open therm and so is the baxi which is great. It must wired correctly though. Bexi is great for a budget boiler 👍
Heat Geek thanks very much. The installer guy knows his stuff to be fair so I know I’m in good hands 👌
An eye-opening video that stopped me purchasing the wrong things, no doubt. Thank you!
Please can you advise the best solution for me?
Medium-large-ish flat.
Worcester 15Ri boiler powering:
10 x radiators spread out.
3 x towel rails in the bathrooms.
Hot water tank.
Main issues:
(1) Night: Heating is off (preferred). But one bedroom gets too cold (drops to 16C in cold winder with the heating off).
I use an old-filled electric heater connected to a smart plug that goes on and off every 15 mins. I'd rather just use the radiator but that's wasteful based on my existing controls.
(2) During the day probably only one room is occupied (sometimes two), but I have to heat the whole flat. Wasteful. So it means constantly reaching for the thermostat to manually control the on/off. I could use another electric heater and smart plug but this approach is just like sticking on band-aids.
What I'd like to achieve:
(1) Have a device that controls the heating and hot water (as now).
(2) Individual control of the room you want to heat, when you want to heat it. Solves my main issues above.
(3) Set a timer to turn on/off the heating by room (or by radiator if there are smart TRVs that do this).
(4) Smart enough to control based on other smart automation in my home (e.g. motion sensors etc.), and voice-controllable by-room using Google Assistant, and preferably detect when a window is open to shut off that radiator.
(5) Avoid WiFi if possible. I use SmartThings for all my smart home stuff, which works on Zigbee. I haven't searched extensively but I think there probably aren't any Zigbee-based thermostatic controllers and smart TRVs, yet. Overall this point is less important.
(6) Preferable something I can install by myself. I'm handy enough. This is the least important because it's easiest to pay, smile and get it solved.
Note: I'll avoid swapping out the bathroom TRVs otherwise they will look pretty unmatched.
Any help appreciated!
Which megaflo type boiler and controls would you recommended in a house with radiators and proposed underfloor heating?
I have just replaced my ancient oil boiler with a Stiebel Eltron WPL 25 ASHP
which seems to be working very well - except that I was also persuaded that my existing Tado smart stats would not be compatible and had to be replaced with Stiebels own Easytron Connect system. But in most rooms, there is quite a variation between the target temp and actual. I cannot see how it can possibly be otherwise as TRVs are sensing the temp of the hot water entering the TRV rather than the room temp, and closing them off long before the room gets anywhere near the target temperature. With the Tado system, I also had portable room stats that effectively overrode the TRVs. But I would appreciate knowing if you have experience of the Stiebel system and what can be done about it. Thanks
Any recommendations for the vaillant eco tec pro?
With vailant we recommend any of their own controls such as the vrc700 or vrt350f
ugh..bg music too loud
Great video, a little easier for me to understand!
I’m trying to get the most from my heat pump (Mitsubishi ecodan 14kw)! Its heating 4 bed property with UFH downstairs and rads upstairs. It’s zoned using 2 nest e thermostat and I have started to use the Eve TRV’s to help regulate each room a little better (fall back temp set to 18 degrees). I feel I may be going too far so any advice welcome.
Best to use the ecowas control.. this is the downside of mitsi hps.. crap controls imo
We already have a boiler that support weather comp so adding the sensor is a low cost addition. Would weather comp be suitable for a property that mainly heats first thing in the morning and then again in the afternoon/evening? Or, would we be better off heating (at a low level) in the middle part of the day, so avoid a large drop in temp. Our current thermostat is not smart (or opentherm) but does allow for scheduling throughout the day.

Please note that tado has just re-released it's BUS control function on the wireless version! Only if you buy direct from them though, for now. Doesn't work with heat pumps yet.
Yeah I'm super pissed about this
It’s still possible if you get the extension kit.
@@davidmcgettigan wireless extension is still available. It doesn't modulate though.
Thats why i build my opentherm controller coupled with home assistant for automation :) not dependant on the "cloud"
Does that mean the TADO no longer modulates the boiler is new installs?
Hi, been following you for a while now, great (if sometimes overwhelming} advice. Coming from an instrument, automation and control background, I'm amazed by the lack of technology built into our homes. Anyway, long story short... I live in a 1990 built four bed detached house and recently had my old (1990) boiler replaced with an Ideal 24+ heat only boiler. It's controlled by a Drayton Lifestyle controller, basic room, TRV and cylinder stats. I'm looking to make it "smarter" and am baffled by the choice of options. I was looking to change to hot water priority in conjunction with weather compensation but with the boiler being mounted south, I'd have a bit of a problem mounting a wired sensor on the north. Now I'm looking into the easier option of Ideal's Halo controller which being load compensating, would give gentler control to the heating. Can I combine the two? With the boiler being Open Therm, what route would you suggest please? A bit of a big ask but any advice would be appreciated. Many thanks, Phil.
Great video. Nice to watch someone who really seems to know what they are talking about.
I am looking at replacing our wireless thermostat at home and we have a Worcester Greenstar Ri system boiler which has modulating control so just need to decide on stats now 👍
We have same boiler! What did you go for in the end?
It all got too confusing so we’ve not done anything yet - just put on new TRVs and running the old Honeywell wireless stat still 🙄
Okay this video was a couple of years ago but hopefully the offer to recommend still stands. I inherited when i moved into a 50-year-old house an open-vented heating system with a Worcester Bosh GreenStar i18R boiler and HIVE controller. Not a great combination but I've removed the old last century copper cylinder and converted the system to unvented with off peak electrically heated SunAmp (PCM) Heatstore for domestic hot water so I can lower my flow temp without compromise. However, the Boiler is now 9 or 10 years old so although I'd like to dump-the-gas I can't financially having installed Solar PV and Battery storage. Question is what is the most cost-effective, Eco-friendly way to modify/control of the i18R Boiler and is is compatible with a more efficient modulating control strategy?
Hey…. awesome video explaining the details about thermostat/boiler operation. I got a new boiler installed last year, which is a Brötje BBK EVO 22/20i. Would you be able to check/confirm if this boiler is able to be connected to a Nest Learning Thermostat 3rd gen? I live in Germany and it seems to be hard to find this information out. And what other smart thermostats would you recommend?
This is so so helpful - many thanks! But I'm still unsure on the best way to control heating in our 4 bed house with largely open plan downstairs. 2012 Baxi Megaflo 2 Compact 32 System boiler. WFH so at least one room used most of the time. Need to be easy to use, better at keeping us comfortable and help us save energy too. What would you recommend? Tado? Nest? Drayton Wiser? Something else? Will SRVs help or hinder? Really appreciate all your efforts to educate and improve home heating.
What a fantastic video! Thank you so much for the detailed explanation. I was on the verge of buying a smart heating system and whilst watching this video heard a voice saying "You know nothing John Snow!"
Time to check the most appropriate setup for my home, rather than the "best" system based on reviews.
Yes 100% mate. Great comment
As you suggested we comment with out boiler models, would you be so kind as to advise what system would be best for a Vaillant ecotech Pro 28 boiler? Would this support the modulating thermostats? I have 13 radiators in my home and it's a victorian mid terrace.

Hi, I have a Potterton Assure Combi 30 boiler in my two bed bungalow, I'm looking for a smart thermostat to save me fighting with the one I have and hopefully save some money on heating. I have heat sensitivity so ideally looking for one with at least one radiator control for my bedroom/office. Looking forward to see which you recommend.
Hoping you can help. Came across your video when researching smart stats. Very informative except I have no idea what would work with our boiler. We have an Ideal Independent Combi 30 which I believe is around 3 or 4 years old. We have a 3 bed terraced house but one bedroom is not used as often as it is my step son's room and he stays every other weekend. Can you recommend a couple of options for us that might work? I feel like we are always either freezing cold or boiling hot in winter 🙈
I have Alpha HE33 Combi. I have 2x Nest thermostats at present controlling 8x MiHome ETRV's and i'm not happy with them. What would you suggest, happy to rip the lot out and start again if needed. I tend to only heat the bedrooms in the morning and evening to 19deg via a schedule and the rest of the house to 22 deg.
Thanks so much for this. I have a Worcester Greenstar 37CDi Combi Gas Boiler in a 3 bed detached house. Can't find out if it's modulating or not as it seems to have been replaced (it was here when we moved in)
Excellent video as always. I have an Intergas 18OV boiler on a Y Plan in a solid walled end terrace. Currently no weather comp. Cheers!
To be honest with that set up your heating load is probably about 7kw which is what the boilers minimum output is anyway so you might be better off range rating it.. weve got a really cool method to test your real world heat loss and range rate your boiler!!! Check it out..

I want to replace it with a smart thermostat but am unsure which one would be best for my home and current system. Any advice would be much appreciated! Thanks in advance!
Quick question - we have a wiring centre to take care of underfloor heating which has separate room stats, and looking to a nest for radiator control and hot water on a Worcester Bosch system boiler. Looking at the heating controls for the underfloor, it doesn't look like modulation is possible so how would the 2 systems interact with the boiler?
Hi, mine is Ideal Logic Heat 15, which thermostat is suitable? Nest or Hive…. Many thanks and keep producing this kind of informative video👍
I have a nest with a gloworm conventional boiler. I have found the nest to be pretty good - however we have an old house and the room the thermostat is in never matches the rooms the radiators are in. I think I should add smart thermostat radiator valves or even a second nest. Do you recommend any types of smart radiator valves with the nest? Also can you even add a second nest to use as a second thermostat

A few years ago I had a viessmann vitodens 100 combi fitted to my 1970s 3bed house. I decided I want evohome as my control now I'm wondering if I made the right decision. As far as I know it doesn't have opentherm enabled and definitely doesn't have an outside sensor. The boiler always seems to come on and off in short bursts, ive reduced the flow to 55 and this seems to help. But due to my lack of fully understanding I feel its never been set up correctly. I don't know who to turn to and what to ask for.

I have a Potterton Assure 36, 3 bed semi, 2 zone heating using horstmann dial thermostats. Wired back to a horstmann controller
Many thanks 😊. Pottering assure is open therm so I would probably suggest the nest for higher budget.. but be aware if not installed correctly it will not modulate the boiler. Lower budget honeywell t4. Even lower budget would be to keep the stat you have and get the weather compensator for the boiler and a turn on WC mode. If you fell me where you are I can suggest a decent engineer 😉.
Heat Geek I was thinking of using the T6 with Z-wave to connect to a smart home hub. Just need to look how it would work if I got the temp sensor for the boiler. I live in St. Helens in Merseyside 👍
@@rhysslater8127 t6 is a great stat.. i find all goneywell controls a little jumpy on the flow temperature though. The benefit of working with your HA might outweigh that though. There is no right or wrong really.
Except for on/off stats.. they are wrong
We got a new worchester Bosch 4000 30kwh installed . But the ambiance in the flat feels now very humid. This never happened with our old boiler (we changed it because the tanks were taking too much space otherwise it worked like a dream for 15 years).
Your boiler is hugely over sized. Your flat o lying needs about 4kw so is a struggle to control. Range rate the boiler to its minimum output. It will help
Thanks for the video explains a lot, My boiler is Baxi solo 12 he, 4 bed house around 10 yrs old boiler the same age. Currently have a hive but looking to change, I do also have tado trv’s in most rooms.

Yet another really helpful video. Yesterday you pointed me in the direction of a video of yours that explained why I should not necessarily be turning off radiators in unused rooms. This got me also asking if I have a boiler that is able to be regulated.
Well the first evidence I had that this might be the case was that one night I accidentally left the heating on at a higher temperature and in the morning I noticed this because my gas usage in the middle of the night was not zero but also it started according to the app started off relatively high and gradually reduced the rate of usage until I spotted my mistake in the morning and I turned it off. I guessed this could be due to a regulating thermostat or it could be the boiler getting the flow temperature up and then using less gas to keep it there.
The next clue was when I thought I'd try and find the flow temperature setting on the boiler (A Remeha Calenta Ace 40c) and when I went to the menu according to the manual instead it gave a message "See RU" and I looked this up and it suggested that this was because I was connected to a regulating thermostat (I have a Honeywell Home, no idea what specific model but it is a black LCD display which is now beginning to fail so it cannot be read and so everything has to be done via the app).
Finally I dug out the installation manual and it has something called an R-Bus connector but according to the installation manual it will support R-Bus, OpenTherm, OpenTherm Smart Power, and on/off thermostats with the same two wire connection. I've also see that it has some other options.
Something they are warning about is that if you are using an OpenTherm thermostat then you cannot wire a frost thermostat in parallel on the same two wires. Your video discussed that your smart thermostat might have an exterior thermometer to help regulate demand, but the boiler also has provision for a separate exterior sensor. The boiler also has several other possible sensors, one appear to be for a temperature sensor on a hot water cylinder (we don't have one), then they have something called a BL (blocking input) and an RL which seems to be a releasing input.
Don't worry about front thermostat.. just have your 'off' setting at 12c.
I have an 8kw Samsung heat pump in a three bed semi. 1970s build. We have improved the insulation and currently have a on off heat miser stat. I did query about using the Samsung controller as our stat but was told that Samsung suggests using 3rd party controls. What do you guys think we should be using? Many thanks.
Excellent video as usual. We have a Worcester Bosch GreenStar 30 cdi condensing combi fitted in 2010. 1920s semi solid brick wall and suspended wooden floor with air bricks all around in other words absolutely bloody freezing. Which smart thermostat would you recommend?
I live in an apartment with communal heating what thermostat do you recommend ? Is the best thermostat okay?
Fantastic video!
We have a WB 42CDI boiler in our bungalow. What thermostat system would you recommend?
Thanks for your help
We Have a Worcester Bosch Greenstar 30i ErP with a Hive 2 thermostat. Quite happy to change stat since it is a constant battle overshooting then giving us a draught as the house cools again, so can you suggest which is the best for our system. 4 Bed 1 bath semi c 1905 with average / poor insulation.
Great video, I didn't know any of this, what would you recommend for a potterton promax 28 combi erp? sorry if its been mentioned before I could not find it in the comments. Thanks
Great vid
Need help choosing a smart start,
I have a 5 bed house 3 floors, ground has underfloor 5 port and second is rads.
Worcester bosch System boiler with megaflo tank.
What's system would be good for this?
Sitting here with lots of jumpers on and a blanket over my knees - with occasional trips to the boiler boost button to keep the house at about 14 degrees (it's a very old cottage with solid walls and old sash windows, currently -3 outside). The idea of having the heating on all day at no extra cost sounds like a fantasy - but one I'm going to try to achieve. Have a Vaillant Ecotec Plus 618 - which I believe is modulating and an unvented cylinder. Any advice on which thermostat should I go for? Thanks very much for the help. Can't believe it's taken me so long to try to understand it all. I suppose up til now I could afford to be ignorant.
Awesome video. I have worcester greenstar 28si with a telford unvented cylinder. I have a hive installed in the hall (no trv on rad) i cant seem to get the house comfortable. (Hall toonwarm living room cool) I was thinking of smart trvs and / or moving to nest. I also have nest smoke / carbon monoxide sensors too. Also thinking of moving the stat to the livingroom and trv in hall? Any advice appreciated
really awesome video. just spent hours researching HIVE and NEST thermostats, but this pretty much explained everything i needed to know. Ive got a Greenstar 30cdi combi. Youve suggested a Worcester control in another comment previously. However, the boiler is around 8 years old. If I ever replace it, i might not stick with Worcester. So would a TADO controller work with my current boiler? and will it modulate?I guess it might not have a physical weather control.
Best to call the manufacturer and ask if it has bus control. If it does then tado would be a great choice. You seem to took more on board then others well done!!!
Fantastic video Adam ! Thanks for breaking it down for the mere mortals.
Could you suggest if/and which smart stat would work best with a Worcester Greenstar 30CDi Conventional Boiler with a hot water cylinder and external pump for a 4 bed semi detached with 2 bathrooms.
Thanks Nishith. Do you know if you have the internal boiler diverter installed? It can make things easier. I would use any of worcesters own weather compensated controls for that. They have a great WC system. Shame about the aluminium heat exchanger but you can't have it all!
Great video.
I have a valiant 430 weather compensator on my boiler. I’m thinking of adding the smart tado thermostatic radiator valves to my 10 radiators in the house (4 bed 2 bathrooms). Is this a good idea? I don’t even have a thermostat in the house and just let the boiler do it’s thing but want to increase efficiency by not having the whole house heated to the same amount when the boiler is on.
Thanks kindly. M
This is a contentious issue. my guess is that your bills could actually go up if you add them. I would only like you to try it to report the findings but i think you already have a pretty efficint system. Does the property over or under heat at all or is it comfortable?
This video is what I’ve been searching for, it’s surprising how little most of use know about thermostats and how heating works. I’ve been looking for informed advice for weeks. Can you please advise on a wireless thermostat I can use with an Intergas Kombi Kompakt (HRE 24/18 A 2017) my apartment has primarily water floor heating with one radiator in the bathroom.
Your expert advice would be very much appreciated.
hi there. any opentherm device, we like the nest. importantly though make sure its wired correctly or it will perform as on/off. thanks for your comment.
Nice video. A few bits that I would challenge but otherwise excellent. Would be good to see T6R included in your thermostat testing, think you’ll be impressed with control performance especially low load.
Thabks Rob! I need to brush up on modern offerings to be fair.. this could be slightly dated now
I've got the Honeywell Lyic T6R and love it (wired version). It's been out ages. I never could tell whether to have low load control on or off but find with it off it will often ask the boiler to produce a flow temp below 30c (which is it's minimum on my Ideal Vogue C32) so it constantly was cycling off when it hit the say 23c it was asking for as the boiler could not modulate lower. With low load control on it will try to keep the burner on as long as poss. So will fire up with the max flow temp I have set (50c) which is just high enough to stop it over shooting on my boiler) then it will modulate down. If it gets to demand being less than 30c it will just cycle the boiler as it knows what the boiler can go down to. Disappointed with calculation of heating hours in the app though, it's never accurate some days saying 2 hours when I know it's been on all day (assume it wants to calculate burner on hours)
@@richardc1983 ?? Interesting, what do you mean by 'on all day'. I presume the pump will be off most of the time when gas is not being burnt.
Just ordered Drayton wiser with 2 trvs. We have normal bosch Greenstar Ri which doesn't have weather comp (don't think we can get it either). Are the electronic TRVs worth their money? or is it better just limiting heat with normal trvs?
Wow this is brilliant!
Thank you!
Any recommendations for a smart solution based on a really old Vailliant gas boiler?
Any vailant controls. Call vailaint and ask which weather compensation controls work with your specific model
very comprehensive video, love when real information transmittance is the the main goal rather than click hunting.
I have just moved in to a new house running valiant ecotec pro (lpg). I have a nest gen3 from my old house, will this modulate the boiler or do I need the valiant system?
I have a Hive controller with an Ideal Independent+ C30, how can I best set things up to be efficient/ is it worth getting another controller?
Great video. We’re trying to get a bit more control of our heating and save some gas, our boiler is a Worcester greenstar 18ri.
Doesn't take modulating control. Any stat
Great video, awesome content, appreciate it being "simple" as I'm a DIYer. I have a valiant and I'm using a couple of Nests for my room stats. I've not actually connected any to the opentherm connections on nest, there doesn't seem to be any guides, will you be doing anything like this? Also, Ive got a heatmiser wiring centre controlling 4 ufh zones. Do these support modulation, or have I effectively lost this now matter how I connect my nests to it?
No you require cqilant controls to modulate
Always love these type of videos, where you can learn so much. The reason I'm asking this question, is because, I want a boiler/Thermostat for our holiday let (1 bed + 4 other room apartment), and to be honest, I usually get a lot of different answers to this most basic question. We have at present an ageing boiler, which needs replacing, so we have come up with an Ideal Vogue Max 26 Kw. Would their own Halo Wifi ST be the best solution, or some other ST? Or a completely different boiler/ST? TIA
Nest controller imo. Wored for oepn therm
Honeywell Lyric T6 made by Honeywell who came up with opentherm
I have a Halo thermostat with an Ideal boiler - it is awful. The boiler repeats a cycle of overheating the room for maybe 15 minutes then taking an hour to cool down. The Ideal system uses more gas to heat one room than a Vaillant system heating a (very) small house.
Very informative, good video.
Hi, thanks very much for the useful video. I was wondering your opinion though please - I have a WB greenstar 34cdi classic combo boiler in a 3-bed house. This is controlled by two wired Honeywell programmable thermostats (hydronic UFH downstairs and radiators upstairs). One of those is losing its LCD display so I've decided to take the opportunity to go for a smart control system, and have just invested in Tado (liking the interface & particularly seeing the attraction of being able to individually control rooms upstairs). I've not started to install the various bits yet, but reviewing your video, looking at the manual and seeing your comment below, am I right in thinking that Tado will work fine with this boiler but won't do modulation? Is there an alternative you'd recommend instead which would get modulation please, and do you think that would be worth it over Tado? Unfortunately I came across your video after making the purchase and now I'm wondering if I've made a mistake! Thanks, Nick
Thank you sir🙏🏽this helped me a lot
Hi, Great videos, lot's of information, keep them coming. We've got a large house built in 1904 with some insulation, but we are limited to what we can do to improve it further. We have a 22year old Ideal Mexico Super RS3/12 which is non-condensing and i would guess non-modulating. The rads all have thermostatic valves fitted, no room thermostat. I've been looking at Smart Thermostats, used in combination with smart radiator thermostats. Given the age of the boiler (which seems to work fine), do you think I can make savings on heating costs by installing a smart thermostat system and would you recommend any model in particular. - Thanks.
Hi, this is a great video - really useful breakdown! We have a Vaillent Eco tec Pro 24 and live in a 3 bed semi detached with one bathroom. Would be really great to know which thermostat you think would be best for our property
Any of vailants own offerings are perfect as they will all use their own bus control. i.e. the vrc 700. If you call valiant on 0345 602 0262 and ask them which Vailnt controls will work they will give you a full list> or if you get a specific local valiant guru they can help select from the choices, let me know your area and ill give you the best engineer.
Hey, thank you for the details. I have ideal system 24 boiler connected to 2 channel sunvic 307 programmer. There is no room thermostat in the house. And I’m wondering if it is possible to replace my programmer with nest or other smart thermostat so I can have more control over the temperature in my house.
are all boilers capable of putting out a lower amount of heat like you mentioned in the begining? i thought they all were only capable of going full blast until the temp is reached and shutting off?
Hi what do you recommend for am Ideal Logic Combi ESP1 35? Many thanks for this video
I've got a Green Star Heatslave I IExternal Oil Fired Boiler 25/32 feeding our 3 bed bungalow with large conservatory in the UK. The heating is controlled by a single Honeywell home programable thermostat and TRV's on each radiator 14 in total. I am looking to install a Honeywell Evohome system. Comments please? good idea or not? or would a different system work better?
I have a Vaillant ecoTEC plus 637 boiler, heating a Joule 300L Cyclon Indirect Unvented Horizontal Cylinder, and full wet underfloor heating, controlled by Heatmiser NeoStat V2 thermostats in each room. Is it worth installing a Vaillant weather compensation control on my boiler and will this be compatitable with the NetStat thermostats?
Hi, what smart thermostat would you recommend for an ideal logic in a 4 bed detached , Thanks - was looking nest or tado but you clearly know more 😁
Tados all good provided its a logic with ot
Hi Great video. I have a Biasi 35c advance plus boiler with 2nd gen nest. Looking at how the system is working it appears to be running on off right now. I also notice the boiler does not have an outside probe. Can this configuration the modulating you mention? Many thanks for any information on this.
Excellent video thanks, very informative as per all your other clips. We have a 4 bed house, Samsung 16KW AE160RXYDEG/EU and a Hive controller, recently had Hive TRV's too but since watching your other vid, I've now put the standard ones back, opened them full which has improved our cop :) Having said that it's still up and down (cycling? ) albeit less severe so do I simply turn the weather comp down or is there a better stat that's compatible with the Samsung?
Very interesting!
I have a question related to Vaillant systems.
What you call advanced weather compensation is what is called “not active” in “control temperature” menu in Vaillant Sensocomfort? And the basic one is the “active”?
Which one would you suggest for a mi hybrid system with iron radiators with trvs where I am actually running a comfort temperature with 0,9 curve? I am trying to lower it and change settings day by day to improve costs…
Excellent video. The detail is next level, over my head. I would appreciate your recommendation for my heating system please 😊 - Horstmann Channel Plus H37XL with two HRT4-A thermostats (down and upstairs) the boiler is Potterton
Doesn't matter I'm afraid. Boilers too old
