    Looking for smart thermostat advice.

    Hi

    I'm new to the forum which I stumbled across while researching all the different options for smart thermostats.

    In the last few weeks I've gone between Evohome, Nest, tado, Hive, Heat Genius, back to Evohome and then probably round again, I really can't remember!. So I'm here now looking for some advice.

    We have a 3 bed, mid terraced house built in the 1930's. Loft insulation is to recommended depth, all windows are double glazed with shutters being installed soon to the windows in the living room, which has been knocked through to create a through lounge with the former dining room. Four occupants, of which two are shift workers, one part time working two days a week and mainly at home the rest of the time, and a school kid. Current heating system is a Combi condensing boiler controlled by a Honeywell CM927 with Drayton TRV's on 7 rads with an uncontrolled towel rail in the bathroom. The system serves us well but I am conscious of the times that we go out unexpectedly or have visitors over during the cold months of the heating being switched on and the whole house being heated, which to me is a waste. It also leads me to sometimes sit in colder conditions than I should to save a bit of energy. The living room can lose a lot of heat overnight - heating goes off at 10pm with a temp of 20 degrees and I've seen it as low as 14 degrees when I get up for work at 4am. We have shutters being installed in September which I hope will mitigate some of that heat loss.

    I am leaning towards Evohome because I am happy with the Honeywell product I have at the moment and I think the flexibility of the system fits with the fluid nature of our home being occupied, but, although I can justify the cost I am wondering if it is overkill in a house our size. If not Evohome is there any other system that comes recommended?.

    If Evohome is the recommendation I would like to know is if I can bind the current BRD91 that we have with the Evohome controller, and also if the TRV fittings are compatible with the HR92?. If so it would save me paying for an installer as I would be willing to give it a go myself. Also would it be recommended to have a HR92 on the small rad in the bathroom or just leave that with a Drayton and let that and the towel rail look after the heat in that room?.

    Any advice will be much appreciated..

    hi

    evohome in your scenario will be ideal and the installation very straightforward:

    the evohome controller is supplied with a new BDR91 so you can simply exchange the front of the unit (clips to existing backplate)

    the HR92 will fit your Danfoss valves by fitting a simple adaptor (supplied with the HR92)

    adding the radiator controllers is a simple process using the guided binding wizard

    regarding the bathroom, do you know if your system has an automatic bypass?
    if it doesn't it would be beneficial to keep the system noise free

    installation is certainly possible yourself, if you would like to use a Honeywell trained installer follow the link here and look for Honeywell connected specialists in your area

      Thanks for that top brake, though I think you've misread Drayton for Danfloss, will the supplied adapter still be suitable?.

      The boiler is a Potterton Performa 24 Eco HE which has an automatic integral bypass, is that what you are referring to?

        You wont need an adapter with Drayton so thats even easier

        That's good, so you wont need an external bypass either, so cool to add a HR92 to your bathroom radiator too

        Hope that answers all your queries?
