    Like you, I never found the noise intrusive, now I have the irony of my wife saying everyday ‘have you noticed how quiet the radiators are now’ when everyday it was ‘do they have to be that loud’😀

    You need the Hub, that calls for heat. In its simplest form the Nest has two no volt contacts that open/close to demand heat and the Evohome can do that easily via a BDR91, you’d have no control over...

    You need to determine which is the closest format of your heating, for example mine is a Y-Plan (so has a 3-port valve) and I use a BDR91 for the heating demand and a BDR91 for the HW demand, with...

    Its the laws of physics:

    ‘the specific heat capacity of humid air is greater than dry air and humid air will take more energy to heat by a given amount.’

    You could just install another Controller and use one for upstairs and one for downstairs giving 24-zones maximum and the two controllers can run independent schedules. With more zones upstairs, then...

    How old are the batteries and don't take any notice of the battery indicator, it tends to be over-optimistic. Does the problem follow an HR92 if you swap a errant one with a known good working one?

    I'm indebted to this forum as it answered my query quickly and with clarity. Probably for those who don't use this place the installer explained it all to them. Thanks chaps.

    Ah yes but to me Heating off is not the same as DHW off as nearly every system has separate controls for HTG and DHW. I'll try 'away' ironically the only one I have not tried as it says temperatures...
