[@enemyofthestatewearein7945]

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.

[@Ifitaintbrokedontfixit]

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!!

[@synappticuser5669]

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

[@robertrosenberg]

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.

[@oldbutstillcurious3615]

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.

We have a Valiant Eco Tec Plus 937 with VRC 430 Weather compensator. 4 Bed detached house occupied 24/7 (work from home), 9 Rads. Often I have to adjust the heating curve from with the settings in the spring/autumn, as I understand this is basically the same as how "aggressive" the modulation is. The problem is the whole house is set up as one zone and I want individual control per room/area (downstairs is open plan). I feel like the VRC430 does a good job of reducing HC water temp to only what is required but the issue is we have too many rads on when we don't need them on.

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.

I am looking for a suitable smart trv system. I've a Worcestor Bosch Greenstar 15i system boiler with an unvented santon 170L tank. it's a 4 story town house. thermostat is in lounge, currently hard wired honeywell DT90E with just Black and Brown connected. Ground floor kitchen is always cold compared to living room and top floor always warmest. I've been looking at Drayton, Tado and Worcester Bosch EasyControl. Currently favouring the Worcester Bosch as I'd hope they'd integrate the best, plus I want individual room control so each room is heated when necessary. Can't afford to TRV every radiator (kitchen has 2, hallway has 1) so planning one for each bedroom, one for kitchen, one for lounge. Currently all radiators have standard TRV.

[@HeatGeek]

what setting are your trvs on? smart trvs have their place but i like to fix organically first if pos

[@nickdjurovich]

@@HeatGeek The ground floor is just always colder (kitchen, hallyway, downstairs toilet, front door). The kitchen has lots of glass (windows and french patio doors). The thermostat is on the first floor in the living room which is 5'c warmer i'd say. So the thermostat is in the wrong room. If it was a wireless, I'd just move it. Back patio doors are used as main exit to/from house. Front door is mostly only opened for deliveries. The kitchen is some 5'c cooler than the living room I'd say, the house getting warmer the higher you go. Top floor is sometimes insufferably warm in summer. House is a 2012 with an EPC I think around 76 so very well insulated. Just think having one thermostat in the house is a bit antiquated now and it means even less with a 4 story town house where you are more likely to get bigger temperature differentials. I prefer the idea of any room in the house being able to call for heat. Rather than one room decide for the whole house :) It's all very well the TRV in the kitchen being on 5 if there's no hot water flowing to the radiator.

[@HeatGeek]

@@nickdjurovich believe me. I understand your set up very well. You can do things with the system you already have. With the living room thaty has the thermostst in, you need to fully close down that locksheild, then open it up a quarter turn. that will force the flow to the ground floor radiators rather than the living room getting up to temp quickly and turning off the whole system. Radiators on the upper floors should already be diverting flow to the ground floor if the trvs are set to 3/3.5. Smart trvs cannot resolve the temperature stratification issue in town houses any more than a proper syetm balance and use of these techniques. I have done this on many modern town houses. If your going out to buy a system regardless I would suggest tado wires to the bus terminals. But that will not work better than a correct commisioning, it will just emulate correct commisioning.

[@nickdjurovich]

@@HeatGeek I've locked down the return lockshield valve and opened a quarter turn and will see how it goes. However, with the kitchen cool and the living room staying warm, it would take the living room to cool down to switch on the CH, thereby, making using of the reducing living room flow and kitchen would warm up. But it's the kitchen that suffers the most heat loss (windows, opening doors etc). If the living room doesn't cool down, it'll stay the same. Cool air will stay down stairs and the warm air will stay in the living room, because it's selfish :D

[@HeatGeek]

@@nickdjurovich yeh your house will try to stratify. ground floor radiators are supposed to be sized larger to account for this when doing heat loss calculations. giving over flow to the kicthen should help with this, if your kitchen ever gets near target temp it will close the trv and divert excess heat to the living room. `the room with your stat in shoudl always be the last room to heat.

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.

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?

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/

[@HeatGeek]

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

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

[@NickAskew]

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.

[@HeatGeek]

Don't worry about front thermostat.. just have your 'off' setting at 12c.

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!

I do have a 3rd gen Nest Thermostat from my previous apartemtn that I can use, but I don't have to use it if I can come up with a better combination of boiler/thermostat. Is OpenTherm good enough for me just get a boiler that is OpenTherm competable or will have have much better results in getting boiler with it's own prepriatory bus / thermostat? If OpenThem is good enough then which boilr would you recomment for me to pair with ? Thanks

[@1over137]

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've just got a heating enginner to install a Viessmann 100W-35 combi boiler with Nest 3rd Gen thermostat.

Looking forward to hearing your thoughts.

[@HeatGeek]

Hi. You need the honeywell 'open therm bridge' and to wire this via the open therm terminals. This will modulate the boiler and reduce the overshoot. If you go on the honeywell website you should be able to find an installer that will understand this. For now, lowering the flow tmeperature may help reduce the overshoot.

[@andreaslenahan4416]

Many thanks for the quick feedback! Just a quick update: Opentherm bridge s installed on X4 11,12. There is still a jumper cable across X4 4,5 (which the manual suggests to remove). Does the evohome system actively learn the zone overshoot to correct it? Thanks again.

[@HeatGeek]

@@andreaslenahan4416 Hi. I'm not sure about removing that bridge in afraid, I think you might have to leave it in but beat to call IG technical. Regarding the learning. In the evohome controls there is an option to turn on optimum start/stop. I havent found this amazing historically though and seems to get the house warm extra early. Just a note. Your property is probably less than 6kw load in the depths of winter and will have an even lower kw requirement as outside becomes warmer. Because your boiler is so large its minimum output is 7.8kw so you will still see cycling throughout the year. This is whyni always advise the smallest bouler possible.

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

@@redivan75 unfortunately I am only able to contact the UK branch manufacturers.. different peramiters are enabled in different countries and the UK tech support won't be familiar with Bulgarias peramiters. We don't actually have bosch here.. its sold under the 'Worcester' brand.

@@HeatGeek yep, I know... this model actually appears here in our market and aims lower budget segment (250 EUR cheaper than 7000i), can't drive external pump but in my case it's not needed for heating a flat.It's strange, because they offer better modulation than Vitodens 100 W and control software/hardware comparable to Vitodens 200 W (more than double the price of the boiler).

@@redivan75 not comparable to viessmann 200 controls in my opinion but yes certainly better than the v100.. sounds like you know your onions!🌰
