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.

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.

This whole channel is so good, technically, and so interesting. Thanks.

This was totally unexpected and incredibly helpful, thank you! So refreshing to find straightforward and valuable content

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!!

Great video and a perfect explanation that will back up us installers and what we’re trying to achieve with our customers. 🙌🏻

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.

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 + 👍🏼

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.

I understand all this but god help me I can’t explain in this way when facing customers questions. Brilliant 👍🏻

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.

Which megaflo type boiler and controls would you recommended in a house with radiators and proposed underfloor heating?

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.

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!

Loving the new set Adam! Your production value is really taking off!

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!

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.

Well presented mate, miles ahead of other heating engineer brethren.

Excellent and informative. We will be directing our customers to this if they are seeking further info. Keep these up Adam, they're much appreciated.

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.

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?

Nice video, can you include some of the major stats used for UFH too... Heatmiser neo and salus quantum. Thanks...

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?

Many thanks for this! I have a Worcester (greenstar 30) boiler that supports opentherm. I have 2 zones (1 rads, 1 UFH) and HW tank. Currently have Hive but I now recognise that this is a poor solution. What are your thoughts please?

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.

Any recommendations for the vaillant eco tec pro?

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

what thermostat do i need to used on my Vaillant Ecotec pro 28

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 🤣

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?

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.

Hi i have LOGIC Combo 30 boiler which modulating smart thermostat would you recommend? Many Thanks for the advice

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!

Thanks for an amazing informative video. I a Baxi Duo-Tec combi 28 HE A boiler. Which smart thermostat controller do you recommend ?

Thank you sir🙏🏽this helped me a lot

ugh..bg music too loud

Thanks for the info! What would you recommend for an Alpha Intec 26ce boiler?

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 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.

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?

Hi. Thanks for the video. I have a potterton suprima 40L with a water tank s-plan. What would be the most suitable stat? Thanks

I live in an apartment with communal heating what thermostat do you recommend ? Is the best thermostat okay?

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.

Hi what do you recommend for am Ideal Logic Combi ESP1 35? Many thanks for this video

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?

Thanks for your very helpful video. I'm about to get a Ideal Vogue Max 32kw boiler installed. Which thermostat would you recommend I get fitted with it? Much appreciated 😃

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?

Hi thanks for the video What’s the best wireless thermostat for the glow worm betacon 4

What would you reccomend for use with and Artison E-Combi EVO? I've been trying to find info myself but it seems to be a bit of a minefield! Cheers

I have a Worcester Greenstar CDi Compact ErP. What smart controls are best for me? How do I tell if it has modulation? And how do I get the most efficiency out of it. I hate the Drayton thermostats (multi zone) so want to replace with smart thermostats.

Really helpful, I’m looking at a vaillant 832 or 835 combi as a new install, but currently have a Netamo ( about 2 years old) and just brought 2 x Google homes speakers. Do any of the new smart modulating thermostat work with google assistant? Thanks in advance for any advice.

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

Hi I have a vaillant thermocompact with a separate water tank which currently has a Danfoss TP9000 controller in a 3 bed semi detached house. As I am working from home most days I would like to heat two rooms which are both downstairs, the one I work in gets cold very quickly which is an extension and at the moment I have to heat the whole house which is a waste. Would you be able to advise a smart thermostat but also smart trv's. Do smart trv's work with the controller as individual temperature gauge and then turn the heating on as if the controller is in an unheated area of the house during the day my concern would be the trv in the extension would show it is under temperature and not heat up as the boiler would be off.

I have a baxi modulating combi with basic weather comp clipped to the flue duct outside, would a tado stat connected via opentherm increase efficiency or would it confuse things with 2 devices teliing the gas valve different things? Only have an on/off - boiler plus stat at the moment. im in a 3 bed mid terraced victorian house with 6 radiators and 300mm loft insulation, suspended uninsulated floors... Thanks 👍👍

Amazing video. Thank you!

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

We have a remeha avanta plus and live in 1980s 3bed detached house. Are you able to recommend which smart heating product to go for? Thank you

What would you recommend for a Vaillant ecoTec plus 831? I’m also looking to control individual radiators on a timed basis

Great video, Very informative!

Very informative, good video.

Hi - I have an Ideal Logic + Combi C30 - what smart heating can you recommend? many thanks!

This video is excellent. I have just bought a house with a GREENSTAR CDi CLASSIC ErP which is modulating (a feature I had no knowledge of prior to watching this video) which for the central is run to radiators currently with no TRVs and a wet underfloor heating system in the kitchen. I’m trying to decide between upgrading to Nest controllers and attaching either basic TRVs/Energenie TRVs and the Tado system with their own TRVs. Which do you think is best for our setup with two different inherent zones from the underfloor + radiators. Is there anything extra I have to purchase for these systems to account for the modulation?

Hi great video thanks.. stumbled upon it while looking for nest controller good enough to replace my old Honeywell one.. .currently my boiler is glowwarm combi boiler... I am told to replace it in an early or so.. so please can you advise fir a 3 bed semi in Berkshire, what would be the combi boiler I should choose to give me consistent hot water in my top floor shower.. second what snart wireless controller to buy pls..

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

I have the Worcester Bosh 30kw life boiler, thinking if the hive active thermostats. Would they be the most efficient or better with nest?

Hey good video! I have an ideal combi condenser boiler in my 4 bedroom house. I’m think of changing controls over to a smart system including smart radiator valves. So I can adjust different rooms remotely at different times of day/week. What would you recommend? I was thinking possibly tado. Thanks in advance

Great video, but I still need help choosing the right thermostat. What would you recommend for a Valiant ECO tec plus 630? London end of terrace victorian house C1860. Many thanks.

I've a baxi 800 with hive (3 bed house). Is it best to keep a set temperature or turn on/off ?

Hi, I have a Baxi System 35/60 installed in my three story mid-terrace 4bed 3bath home. My 24 hour timer thermostat (Flash Immermat) has recently broken (no matter if I turn it to full on, timer, or full off it remains on and heating 24/7). 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!

I have a Ideal logic system s18 boiler, it has a primary controller/timer and a twisting thermostat, controller is by the boiler thermostat is in the hall by the front door, 3 bed house all rooms have 1 rad aprt from lounge that has 2, I have been looking to add smart therm pref one that can be controlled with the echo dot too, recomendations?

Great video - very easy to follow! However I’m letting the side down as I can’t work out if my boiler is modulating or not. What set up would you recommend for a Baxi 400 (conventional) - in 3 bed terrace house? Thanks.

I'm about to buy the Nefit Proline NxT HRC24/CW4 and am thinking of buying the Tado or Netatmo thermostat because it works with Apple Homekit; would you suggest one of the both or maybe something completly different? any help is much apprecieated!

Hey thanks for this video I have a relic of a boiler the ideal esprit 2 24 and currently it has no thermostat and want to add some wireless controls, I was looking at the Tado v3+ system what would recommend? cheers. :)

I have a saunier duval boiler (Vaillant group ebus) whit the vsmart, yet it loses the connection often between the termostat and the controllor down, can i replace it with a Tado (it is wired) and still modulate according to the outside temperature with the tado V2? Thanks

Thank you for the informative video! We are renovating/extending and will end up with a 5 bed 3 bath home and will be putting in wet UFH as well as radiators. Which boiler/Megaflo/smart thermostat set up would you recommend?

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

Hi, first up great information!! do you have any ideas about nefit trendline II (build by nefit/bosch) at the moment i use a nefit easy thermostat but i’m looking to tado as this has the option to only heat the rooms in use (during working from home) and they could help heating parts if the house with an airco unit. Rooms with airco heat will nog use any gas.

Hi, I have a carrier weathermaker 8000 ts. What is the best smart thermostat that would work. thank you.

Great video! What would you recommend for a Baxi combi? 33HE (5 years old).

I’m looking at the Tado smart controller for a Vaillant air source heat pump. Would this be the best system for me with having UFH in the main living area on the ground floor but also wanting to keep the bedrooms and other rooms we don’t use as much that may require lower or higher flower temps to maintain comfortable room temps.

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.

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?

Very good video, clean and well explained.

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.

Hi I've got a (baxi duotec combi 24 he a) boiler and looking for the best smart thermostat for this model. My current one just shoots up the heating then turns off when it reaches the temperature. I want one that can steadily keep the temperature. Thanks

I have a Telford Stainless Products Tempest hot water cylinder with a Honeywell programmer, its in a communal heating building. What smart thermo should I get and also is this cylinder modulate like you said? Thanks

Fantastic video! We have a WB 42CDI boiler in our bungalow. What thermostat system would you recommend? Thanks for your help

Hi Heatgeek, can you please advise the appropriate smart thermostats that will modulate my Vaillant Ecotec plus 824 boiler?

Hi I have a idea logic combi esp35 but I have just a Siemens controller I would like to upgrade to the nest. What would you recommend I have 2 zones upstairs and downstairs but a Plummer had told me he could wire them together so I have one controller which I could keep down stairs. I want to get the most from it Thanks you great video

Hi there. Great video. I wanted to get your opinion on what is the best smart thermostat controller to go with a Worcester/Bosch 35 KW Greenstar 8000 Life regular boiler. I am considering the Nest 3rd gen thermostat but not 100% sure. Would love to get some advice from you .

Great vid, thank you. I have recently installed a modulating thermostat for my boiler and found that it was constantly above the room set point (20deg). I then adjusted the flows through the rads and now it can’t get to set point. I’ve got the max flow rate set to 50 deg which should be plenty. Is my issue the flow rate/boiler aiming for delta 20 and thus affecting the thermostat’s ability to modulate?

Hi, I have a Worcester 24si 11 or (ii). Which Smart thermostat would you recommend, I currently only have a programmer. Thanks

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.

I have oil boiler with on off two wire thermostat and it is damaged and i have ebus thermostat two wire can i replace it or not?

Not a tech geek, a Reg'd Blind fairly fit pensioner. 4yrs ago needed a new boiler. Got the same national company to install it - Vaillant eco Tech 832 + a "free" TADO. No manual came with it, the electrical guy who installed it gave me a rapidfire explanation of how to work it. I told him - no comprende but reply was "every day is a school day." I sleep with my bedroom window open summer and winter and open all the other windows throughout the day as weather allows. The main radiator in the hall has the TADO temp control near it. This radiator positively glows especially when I have turned off some of the others. This leads me to think the TADO is meant to heat the whole house to a specific temp and will push this radiator to do that making the hall swelter. Prior to the TADO I had a timer and each of the thermostats on individual radiators set to my preference with no problems. Fuel bill up. Thoughts please? McIntyre

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?

Hi, which smart thermostat would be recommended for a Glow worm Betacom 24? Looking into getting one fitted. Thanks

Many thanks for the great and very instructive videos, I have an Alpha E-Tec 28 boiler and I am thinking of installing their Climatic controller with the external weather probe,would this be a good solution? I have an Owl Intuition system at the moment which is a bit hit and miss

Hi, I have a grant vortex condenser oil boiler, it's 2.5 years old, 5 bedroom, 3 bathroom dormer house, attic has new spray foam insulation and currently have a Hub controller, which is too temperamental to rely on. What controller would you recommend?, bearing in mind I've found the use of the app really handy and I have Google Alexa.
