Once they're set I hardly ever adjust them anyway so really can't see the point and the money saving achieved by these would never get anywhere near £800


I'm the kind of person I guess... We have 12 radiators but there are only 2 of us in the house. There are rooms that get used for an hour a day or less (e.g. The room my wife gets ready in in the morning or spare bedrooms) so they're only heated when we need them. Also means we can adjust temperature in a specific room from the sofa or that guests can adjust temperature in their bedroom if they're too cold.

When we had it installed we worked out the ROI was 2-3 years based on our usage. Maybe it's longer than that in reality but it works well for us.

Clearly not for everyone though!

I spent around £600 on these a few years back, paid for themselves in just over 2 years based on gas usage.. One of the best investments I've made.
OMG, I would surely not be able to sleep with these Frankenvalves lurking in the bedroom.

I think the math may be somewhat flawed or unrealistic if you’re getting payback in 2-3 years.

I’ve got much cheaper Tado valves and the payback is not that quick but I didn’t buy then for financial reasons.

In reality you would probably never get the £800 back, however I am that kind of person as well. I have 6kw of solar, an electric car and smart radiator valves. I'm on a mission to have a completely bill free house before I retire

It's called a joke, guess it was wasted on you.

I never said it would be a real saving and if you read what I posted I said I'd probably never get the investment back, my ambition is a bill free house for retirement, I'm aware I could probably just put the money away but I am not doing it for financial reasons.

I'm planning to build an passive home in my garden and sell this house also, again the additional cost is probably never recovered, but I'll have a much smaller carbon footprint.

I would suggest you learn to use the emoticons to help you show that you’re joking, as it’s not obvious from your post and will mean that at least some people will take your post at face value - you can help yourself to help others.

As for your other post about it not being a real saving, you posted that after I had posted my post (according to how the thread is laid out on my screen) so it was posted in good faith based on what was known at the time of posted.

My message to anyone that is considering these types of TRV valves is to not consider it solely for financial reasons.

My use case was additional comfort even if I never reap back the initial outlay in savings.

Ok sorry was intended to be witty.

Maybe just updated slow I posted that first but fair enough.

Zone valves can be a cheaper alternative if your are able to fit them.

Also weather compensating thermostat can increase comfort and give good savings.

Yes but you're missing the key variable which is time. Right now I'm sat in my living room with the heating on. Our bedroom is currently coming up to temperature for when we go to bed. Every other room is off. If we had normal TRVs set to specific temperatures then we'd be heating 5 times as many rooms...

Sorry missed your point here. Each of these valves is it's own thermostat (hence thermostatic radiator valve). You set the desired temperature of each room individually and it opens and closes the valve on the radiator accordingly.
Just turn trvs off its more about convenience yes its a good idea but doesn't really save much. To be perfect each room would have a thermostat timer calender which would control trv

That's exactly what this does...
Great system, allows fine control of the heating on all my rooms which saves significant amounts of gas. The old system was all trv too so its definitely a step up in efficency from that. Depending on your valve they can be a bit loud though

If someone has access to a maths / math / sums / calculator tool that can indicate the additional heat loss load from the heated rooms to the multiple adjacent building fabric between heated / unheated rooms I would like to see it. Genuine request for useful info, not an argumentaive challenge. Thanks.
steevojohno14/03/2020 22:03

These heads sit on top of the actual valve and open and close the valve based on the room temp. You can use the temperature reading on the head or use a separate wireless thermostat if you want to take the reading at a different part of the room. They have some compensation built in for them being right next to the radiator and if there are multiple readings it'll take an average. There's also smarts built in to detect sudden drops in temp like a window opening and notify you.

100% my use case too. ROI isn’t a huge consideration but the thought of heating every room whilst we’re only using one seems a waste regardless. Messing around with trv’s sounds fine in principle but it’s not for me.
I have these myself, paid a small fortune 18 months ago. To be fair, there are savings, but I suspect that they will be many more years in before they pay for themselves. Having acquired them, my first realisation was that they don't conveniently fit bath towel rails. Also, if you have toddlers, my recommendation is for you to fit the valve controllers back to front. Within weeks my toddler tore off one LCD rendering the unit useless. Honeywell do not repair or offer spares parts. Doh. All said, I appreciate being able to send heat to specific rooms at specific times, so I'm happy with mine.

Have you got a link to the separate wireless thermostat that works with these valves and the evohome hub?

I know you can set a room to have more than one TRV, but that never worked that well.

Would be interested in adding a separate wireless thermostat in each room if that is available.

Your heating habits change and you heat up a room when you want, not just because it’s on a timer. It’s a complete change in behaviour which results in less usage. ROI is actually within 3-5 years for most.
Whilst individual TRVs can zone and therefore control individual rooms, which may bring some minor savings, its mainly beneficial in terms of convenience and comfort for some rooms to be heated when others are not.

What no marketer will put in the blurb is that the fundamental flaw in this logic of each room being is own zone, is that this can cause much more frequent boiler firing as heat escapes from warm rooms to cold rooms causing those TRVs to call for heat. This can cause the house to feel more draughty.
This does not happen when a whole floor or house is heated.

But savings will always depend on individual usage patterns - ie turning the boiler off more often. But many people won't like the corresponding changes in comfort levels.

The other thing to remember is that you really need an Opentherm or similar controller or an external weather compensator - and suitable modern controllable boiler. This will ensure that the boiler compensates for the building's heat loss on warm and cold days, and how long rooms take to heat up. The savings will tend to come from the boiler firing for longer periods but at reduced water temperature (less gas to heat water), as heat loss is managed better rather than rooms going hot/cold/hot/cold at a single high water temperature.

Agreed. I've had them installed for nigh on 6 years and no way I would want to be without them now. In fact, if we move they will come with us! The best value on the market isn't always necessarily the cheapest, these are made/sold by the company that invented the thermostat, a $100 billion company. Be careful of start ups in this expensive to get off the ground market sector not backed up by huge companies like Amazon, Google etc. as some of these systems can't function should the company go mammaries skywards...

Someone with 16 radiators tends to get higher gas bills than someone with 8 and also can achieve bigger savings with something like this so it's all relative, I guess. Bigger outlay for bigger savings. Evohome doesn't stop saving gas once you've got beyond say 8 radiators!

I'm the same and also got 6kw solar (with Solar iboost) so free hot water when there's surplus generated. Also numerous other smart gadgets in almost every room in my house, turning off sockets etc so nothing left in standby unless essential.

My gas & electric combined over the year works out at £50-£60 per month max (annually less than £600)

Also seems like more to go wrong plus they must also take some kind of battery which has to be replaced, again adding to the overalls costs.

Still not for me but can understand others who like them, but still really can't see how I could save £800 in 5+ years nevermind 2-3years like some have stated?

But surely most people only use the same few rooms in their house anyway? So who turns radiators on and off that frequently if they enter the not so often used rooms?
I might go in my office, I'm not going to warm it up before I enter it to find a stapler who cares if the temp isn't as warm as the living room for a few minutes. Heating your bedroom a few hours extra instead of an hour before you go to bed....this is going to save pennies on a daily basis not £'s. Then for 6+ months a year these aren't even used?
Think people are dreaming that these save £100's every year
Edited by: "steevieboy4u" 15th Mar
I know there's scepticism about saving. I can only tell people what I did, originally had a wireless honeywell thermostat controlling whole house cm973 I think. I Bought the wireless thermostat for the hr92 individual room valves on black Friday 4 years ago saving about 25% of price. Had 10 valves across 8 rooms (2 doubles). I had been tracking gas usage as I'd only moved house a few years earlier and had never had gas before. I tracked gas usage and calculated using unit price. They paid for themselves in the first quarter after year 2 so just over 2 years. Obviously everyone's habits and routine will be different but that's my experience..

I think you've missed the point of Evohome because that is EXACTLY what it does! I know lots of people say 'I just change the non-smart TRVs in my house regularly' but I suspect about 0.0001% of the population keep this up for any length of time before inertia takes hold....

I use the office 9-5, the living room 5-10 and the bedroom after that. I'm not turning on heating in the kitchen when I need something out the fridge or the office for a stapler.

Should I mess about with radiators or should I heat all the rooms I'll want heat in even when I'm only going to use one of them at a time?

And that's just me, the other half has her own wants for heat.
