    Honeywell 4073 issues

    Hi Guys, I'm a complete novice trying to figure out a problem with my central heating/hot water. Problem is that I'm getting HW when the programmer is set to CH ONLY.

    Honeywell evohome thermostat.

    Hey all. Are these suitable for all boilers brands or certain 1s. The Home owner has this already before a boiler has been brought. Was looking at an ideal logic or potterton combi's but he was under the impression that it only worked under certain brands. Haven't come across any of these yet...

    Honeywell Motorised Valve Not Fully Sealed when Closed

    When I have my hot water on and the central heating is off, there is still a small flow of hot water through the motorised valve for the central heating. There's sufficient flow to slightly warm some of the closest radiators. Does this usually mean a new motorised valve or is there something...

    Honeywell Evohome good or bad.

    I'm thinking about installing a Honeywell evohome system in my own house. It looks good on paper but I'm still in two minds as it's a lot to spend. Has anyone out there got experience of fitting or operating it?
