Which smart thermostat?

Nest also supports OpenTherm. Someone on AVF was having a problem with the Tado starter kit they bought as it didn't include some features such as GeoFencing and required you to pay a monthly subscription to get that feature. Not sure if that's still the case or not.

All of those features are included with the thermostat. So not sure why they've quoted those as being premium features.

edit - he appears to have bought a 'cheap' edition, I didn't even know that existed. It was for a limited time:

As for the Premium service: we think every home should have intelligent climate control. That´s why we have offered you a special tado° edition for a limited time only. However, you can always return your special edition tado° by contacting our customer service and of course, you will not have to pay the postage yourself. If you want to, you can still purchase the tado° (inclusive its Smart Climate Assistant and all the features mentioned above) via our webshop at any time. We hope to retain you as a customer!

Any info in regards to this law you're speaking about?

It's called boiler plus.

It effectively means if you are installing a new boiler after April...

The legislation will require all those fitting new combination boilers to include one of the following in their system:

  • Flue gas heat recovery systems
  • Weather Compensation
  • Load Compensation
  • Smart controls featuring automation and optimisation functions

Having an opentherm boiler will tick the last box. If you aren't planning on replacing the boiler anytime soon I wouldn't worry about it too much.
 
Thanks for all the advice. Boiler is only 3years old so will hopefully last for a long long time yet before i need to fork out for a repklacement. Ordered a Netatmo, hopefully here tomorrow before i drive back to the new place on Weds morning.

Pretty sure opentherm would come under load compensation. In that it regulates the flow temperature dependent on the load required.
For instance when I have a radiator first thing in the morning they always ask for 100% soon each rad to maintain the room asks for around 4% then the controller adds them up and asks the boiler for a certain flow temperature.

Definitely worth it over standard tpi, bit you need a system designed with opentherm in mind otherwise the boiler won't be able to go low enough. Mine when it was freezing the other week settled on a flow temperature of around 28c to keep the house warm and didn't cycle at all.
 
Am i right in thinking that for most people who have a fixed routine i.e. 5 days at work, sat and sun off. There will be 0 benefit to having a smart thermostat?

Pretty much, I didn't want one that works out the times itself so with Evohome you set the times for each room and then that's it, the smart bit comes from the optimisation where it learns how long it takes to heat up.

Well, yes and no. You can (and should) still set times you want it to come on, but the savings are when you go out during a time when you had it set to on, or you don't come home as expected. Effectively, it's also good so you can set and forget. I never need to think, best turn the heating down/off before I go out unexpectedly.
 
The nest learning thermostat is making me use more co2 than my old manual one but i bought it so i could turn on the heating while im away so i dont turn up to a cold home..

honeywell do a opentherm stat that isnt learning to set times but will turn down the boiler as it gets closer to whatever temp you set it at, its likely a lot of customers will get this type of thermostat over a complicated 200 quid thermostat as a massive amount of people aren't interested in it, older generation mainly. Im all for more tec but its just not for everyone..
 
Are these worth getting? Looked at them a few times over the last couple months however they seem to have dropped in price recently, down to around £180 from over £200+ (maybe new model inbound?)
 
depends if you care about turning the heating on from your phone.. they wont save much gas, the cost is high because of how it looks, cheaper stuff out there that do the same job. Can only think theyve dropped in price to be more competitive.

Never experienced it anyway, seems like a lot just to be able to control it from my phone.
 
it also monitors when you come in or go away and auto switches on and off. Monitors outside temperature/weather and adjusts it's schedule, calculates how long it takes to heat up so if you want it to be 20 degrees at 8 it will be 20 degrees at 8, rather than coming on at 8, etc. In my experience it saved us a lot of energy, but of course the fact that I can use my phone to control it, plus set up alerts if someone is in the house is a very good bonus!
