Any users? I am seriously tempted to buy it plus all the valves.

We live in a house (just two of us) and having room control would be amazing. Anyone see any material savings?
 
Not got it but something i will be looking at when we get a new central heating system.
Love the idea that i can control each room independently or as zones.

Looks like it can use Opentherm as well to further save money but requires a compatible boiler.
 
Will probably buy it, just wanted to see if it is as good as it looks. I am fed up of constantly changing TRV settings depending on the rooms we are in, and also morning routines vs evening etc. We end up heating most the rads as a result for no reason across 3 floors for only two of us.

Money saving is secondary to be honest, but still interesting to see if it does make a difference.
 
Yeah, we are looking at around £700, I can install it all myself. Alternative is thermo TRVs but wont really work for us, we vary our location throughout the house a lot everyday. Could also do zones but in terms of time/cost to up the floors etc won't be far off just doing this instead I imagine
 
There are only two of us in a 7bed 3 storey house. It'll be nice and economical to only heat 4-5 rads rather than 24. I'm hoping I'll see some savings pretty quick......Once the CH finally gets installed.
 
Also speed as well, our system is good (brand new boiler, we also have a Megaflow which is the best thing ever), and if we only want to do one room, it will heat up so quickly. Whilst we have less rads than you and rooms, (a mere 5 bedrooms!), it's disparate enough to need individual control. I am not worried about hotwater (frankly the fixed programme we have works well) but will add on the hot water part later on anyway.

Spoke to a colleague who has 32 rads for only 2 as well. He is thinking of doing a mix of zoning and Honeywell EVO (he has 2 boilers!).

Its very expensive, not sure you will make savings and time soon, but once setup it should be nice and convenient.

Expensive compared to what?

The single zone wireless remote stat is about £200 which is comparable to all the other "stupid" systems that cannot zone without massive expense e.g. Nest

You can then build on that to suit your needs so a zoned TRV is about £50

Expensive compared to nearly all others.

Its about £400 for the setup with 4 TRVs, £600 for 8 TRVs.
If you were using this without there smart TRVs its a bit pointless.
 
Whilst there will be savings, convenience is probably the best selling point for us. One night we may spend a lot time in lounge, or in office, or in extension etc etc. Way easier to just select a room to warm up
 
All up and running. Very easy to install. Very impressive, the individual control is the best thing ever.

iPhone app could do with more features to match the controller, but superb system overall
 
The only thing that put me off these is that if I was wealthy enough to have a house to justify it and to be able to afford umpteen smart TRVs, I'd probably find the most convenient thing was to have all of the house warm all of the time, rather than bothering to turn down the study when I knew I wouldn't be working, or the guest rooms when I had no guests.

Maybe if some rooms were naturally too hot or cold it would help, but then normal TRVs do that.
 
The stat in the house was crap, so it was either go for a standard smart stat or pay extra for this. The difference wasn't that massive for the convenience, £580 for 8 TRVs and the controller, plus installed myself.

I hear you. BUT. There is no point in heating 4-5 rooms that we are just not using. Or even a whole floor (4 rooms in the loft which wont be renovated until next year or so)

I've not even considered the speed at which we will be able to heat up a room if its not being pumped all round the house.(3 zones)
 
Agree Speed is important. It's like instant heat when you disable some zones. Whilst you could argue that you could keep TRVs off permanently we vary our use of rooms a lot everyday.
 
I suppose it's always better to use less energy than you need to, and who's to say the wealthy don't like saving cash too.

Also the speed thing is a good selling point.
 
After a few days have to say I'll never go back to a one zone system. It's superb and being able to target rooms is amazing. Next step is to get the hot water control but I'm apprehensive a bit cutting into our Megaflow so will contact Honeywell for some ideas.

The physical controller is better than the app, the app seems sluggish and less features.

Only "issue" is if you run only a couple of rads they can be noisy but this is due to the pump and the pressure being high for only a couple of rads. Not a big deal but would be cool if there was a way to turn the pump down if <x rads are on.

Get an auto bypass valve, will divert some of the flow when your only using a couple of rads.
