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.

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.

[@nice8523]

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?

Nice. I love that you don't just pick a product and shill why it's great. You stay concept rather than product. I am creating a DIY heating controller with multizone presence awareness. "Load balanced" and "Cyclic". I am battling "selfish heating" of zones. The living room might ask for heat and be given it, but the bedroom, very nearly at it's minimum sits unheated. I am aiming on intelligent "sympathetic" heating. If one zone demands heat, could any other zones use some anyway? The tricky part for me I have no way to trace "why" a demand for heat was raised, only that it was. To go modulating, rather than cyclic, I just need a trust worthy gadget to hook up to my boiler. The plan being to base the flow temp on the differential between the current and the target and pre-planning warmup based on ambient and differential. No bloody cloud. Want my heating to work when the internet goes out due to an admin screw up that takes 10 days to fix.

Hi, I am currently in the process of buying a house with a Glow-Worm Micron 50FF (located in kitchen with side exit flue). It's a 1600 sq ft 5 bedroom house that's 20 years old and built over 3 floors (the loft was built as two bedrooms rather than being converted later). The heating system was also built with a Gledhill Boilermate to acompany the boiler. I'm hoping to ge the keys in the next few weeks but have been informed by the sellers that the boiler has tripped out a few times in the last couple of months so I've negotated a suplimentary £1500 discount because of this boiler issue. Essentially that means I have £1,500 for a new boiler so can pick one and choose the right thermostat to compliment it but would also work with the boilermate. I had been thinking about Tado because they also have the radiator valves which means I could have more flexibility to set the temprature room by room. The two rooms in the loft will be our offices so will be using those rooms daily but will be a lot warmer than the ground floor where the thermostat would be. We have the Google Home ecosystem so would like something compatible with that (though it doesn't have to be Nest). Prior to watching your video, I was thinking the Worchester Bosch Greenstar 30Ri but now need to start looking at bus controls work with which. What would you recomend in this scenario?

[@HeatGeek]

Hi there. First of all loose the boiler mate. It will force your new high efficiency condensing boiler to continuously work at high temperatures and use much more gas then necessary as it has to provide hot water . Terrible idea for modern boilers. You just need a normal unvented cylinder or a combi STORAGR boiler like a voessmann 222. Note a combi storage boiler is nothing like a combi boiler. A normal combi boiler will not work in a house of your size. I would advise a viessmann 200 boiler with unbented cylinder or a viessmann 222. The reason being is that if you are going to turn the system output down to just your offices the boiler needs to be able to turn right down to match that demand. The viessmann 200/222 is the only boiler capable of that. More on that here.. heatgeek.com/what-is-boiler-modulation/ Tado worked with their old 'km bus' but im.unsire if it works with the new 'plus bus'. Zoning down in thos way isn't always the best option anyway.. you can get more efficiency but using all the rads believe it or not.. or just up and down stairs .. more on that here heatgeek.com/weather-compensation-or-load-compensation/

P.s. Worcester boilers are not exceptional in anyway.. nor are they bad. They are just ok..

[@ravijain1194]

@@HeatGeek Thanks for the really informative response. I will start looking into unvented cylinders and the Viessmann 200 and 222 and how they align (or not) with the Tado smart thermostats. Out of curiosity, does the Viessmann 200 and 222 require an additional cylinder? From what I'm understanding, the 200 and 222 are an all in one system that doesnt require an additional cylinder? I'm just thinking about space and location as the current glow-worm boiler is a small one in the kitchen with the boilermate currently in a storage cupboard on the first floor. If the new boiler it didn't fit in the kitchen and doesn't need a cylinder then I suppose it could go in the storage cupboard instead.

[@HeatGeek]

@@ravijain1194 the 222 does not require a cylinder, its built in. The 200 does require a cylinder to heat. You have to call tado to see if it interfaces with the new viessmann 'plus bus' system.. it did work very well with the old 'km bus' system

Hi I've watched a fair few of your videos which are very informative and I still am not sure whether or not you are advocating 24 hr heating. Having heat on while you are in bed or out is a head wrecker for someone who lived without Central heating for all of their childhood and early adult life which still constitutes a large proportion of the population of the UK and Ireland where I abode. Central heating frost Protection is a good clever idea if somebody dies of hypothermia induring the night under a warm duvet heated by themselves FREE of charge they were going to die anyway I think. Having a warm home 24 hrs a day from here into the foreseeable future is a luxury most people cannot afford. Also have we now start using outdoor temperature controls to tell us whether we should go out for a walk or should we just put on a coat and scarf I remain convinced that for a working person using heat when you get home and or before you get up will save more then round the clock in the average house. For the poor unfortunate people who spend more time at home I would love to see you make a video addressing what they can do to save money even if you have to take your engineers hat off to do so. As a 58 year old gas fitter I really find your videos very educational and intelligent God bless

Hi, I've just got a heating enginner to install a Viessmann 100W-35 combi boiler with Nest 3rd Gen thermostat. I can see that the Viessmann Combi can accept OpenTherm output with an additional wire connected to the Nest hub next to the boiler but the engineer hasn't done this. I asked him how he set it up and he told me it's set up as an Optimum Start Control smart stat. From what I can tell, getting the extra wire and going down the Opentherm route would be the better option to allow for the modulation? I was wondering if you could confirm this?

[@HeatGeek]

you are correct

[@ravijain1194]

@@HeatGeek Legend

[@MSKChess]

I would just like to say that its actually the fan which modulates not the gas valve per se. Most modern condensing appliances are fitted with a gas/air ratio valve and a zero governor operating under negative pressure, the faster the fan the more the governor gets lifted from the valve seating etc While I personally love the idea of open-therm technology I am not entirely convinced. It appears to me to be something similar to the arguments for a slow cooker where if it operates at 100 watts for ten hours it uses the same energy as an appliance that uses a kilowatt for one hour, there being no difference in the energy consumed. I am prepared to stand corrected though because I do understand that open-therm will ramp the fan down when it think it is approaching the desired parameters rather than over shooting it as with a simply on/off room stat. I have often wondered if the same or better can be achieved by simply over sizing radiators and then running your appliance on a fairly low setting? either way the video was awesome I just wish there was more peer reviewed data on the benefits of open-therm with studies conducted.

[@HeatGeek]

Hi bud. Sometimes correct sometimes not. For example the higher end vailants have a mass flow sensor to which independently measures air. The viessmann 200 has a mass flow sensor AND and lambda sensor to further define the mix and so adjusts the ratio. This is how they automatically adjust to lpg or synthetic mixes without any changeover kit. If you have to adjust the has valve in service it will generally be zero governor in the way you described. You are correct about what you are saying about not making a difference on output although your numbers where wrong. How ever your missing condensing efficiency when modulated down.. yes this can be achieved by larger rads but its not 'condensing or not condensing' the lower you go the MORE it condenses. So your better still with larger rads AND open therm. The other thing this doesn't account for is wear and tear on the boiler and system as open therm reduces cycking... qnd of course comfort.. all small gains in reality but all add up to a no brained imo.. Thanks for your comment! Happy to be corrected if you see any mistakes! 😁

[@MSKChess]

@@HeatGeek Its very interesting indeed. I had no idea about Viessman or Vaillant. I cant see why my numbers are wrong though, 100 watts x 10 hours = 1000watts or 1Kw, looks solid to me man, but I am not physicist. I am not sure I understand what you are saying about condensing and efficient but that's my problem and I will need to think about it more deeply. It seems that the lower the running temp the more the appliance will condense therefore the more efficiency we get. I thought it would be the opposite, the higher the temp the more condensing we get. Have you done a video on pipe sizes and how they affect the efficiency or otherwise of a heating system? It appears to me that the trend is for plastic pipes and larger ones at that i.e. usually 22mm flow and return reducing down and feeding 15mm radiator vales. This appears to me to be counter productive because we have a much larger column of water to move around than on say 8mm copper pipe fed from a manifold and thus the system will take longer to heat up and longer to cool down? Perhaps plastic is better because of thermal insulating properties, I dunno. Anyway thanks for taking the time, videos are awesome, kind regards robbie.

[@HeatGeek]

@@MSKChess My mistake I thought you said all day not 10 hours. Your numbers are correct. Regarding condening efficiency, you are better at lower output and ther-for temperature over a longer time. As per your example if we squeeze 1000watts in an hour at high temp is won't comdense. Instead 100 watts over 10 hours will be lower temp and extract more latent heat.

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.

Could you please advise on the best wiring centre to use, actuators (10 needed), 4 zones for underfloor heating, advanced weather compensating controller, thermostats (I think 4 for the underfloor heating zones and not sure how many to get for upstairs where we have 4 rooms with one radiator in each room). Thanks

Hi, thank for your informative video, I have been researching this for a while and left quite confused before watching this. One question I have relates to your statement that TADO supports all Digital Bus languages, are you able to confirm that the standard UK TADO version can be used to replace an existing Worcester Greenstar 2000 RF wireless Roomstat and retain the modulating functionality? Many thanks, Kane

[@jabatecar]

This is my question too 🙏🏻

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 😊. 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 😉.

[@richardc1983]

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)

I have a Glow*Worm Betacom24c combi that is controlled via Honeywell thermostat. Minimum modulation is down to 10.5kW and the MCS heatpump heatloss calcs spreadsheet says my midterrace needs 10kW at a -1.8C design. Wondering if my boiler can do advanced weather comp in any way at all (currently start stop via Honeywell). Rads are fully upgraded to mostly K3s, and "self balancing" TRVs are installed with a system fully balanced and TRVs set to design temps of various rooms (19-21 for me since the 18-22 didn't suit). If boiler breaks (currently in great condition), I'm going for a heatpump after some window/wall work (floors mostly done). This year is about seeing if 55C flow/45C return max can keep the place warm. Heatpump (about 6-7kW after envelope upgrade) right after. What can I do weather-comp wise in the meantime?

[@davidchilton7923]

Hi guys, loving the videos, a wee bit late to the party, but wonder if you can offer some advise on a new upcoming setup. I am getting aa Vaillant Arotherm plus hybrid system installed which will come with its own smart control (either a VRC700 or sensocomfort), but my question stems from the fact I have already installed the Drayton wiser system to allow zoned control/room through smart TRVs. Do you think that the 2 systems will be able to be configured to play nice together to still allow the individual rad control , i.e. with the Drayton system, it replaced the original boiler controller, but assume that the Vaillant control would replace that, so could they be setup in tandem?(will obviously be asking the question of the installer as well, but thought it would be good to get another opinion). Other question would be what would you advise (binning the Drayton and relying solely on the Vaillant control? I know they also offer smart TRVs, but to cover the house would then add ~ £1K to the cost, when I already have a system that will do this. One thought I had if they would not play together directly would be installing the Drayton stand alone, so it could no longer call for heat as not connected to the boiler, but I could in theory sync the schedules, so they would only call for heat when the system was providing heat. Long winded, but would value your thoughts!

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?
