    2 zone CH but 1 zone heats whole house

    Thanks again for all the help with this - firstly the pipes. Yes they are both hot both above & below the valve. The plumber came back again today (I think it’s his 4th visit!). He’s suggested that both of the valves (the ones that switch from A to B) have been incorrectly fitted, so hot water...

    2 zone CH but 1 zone heats whole house

    I spoke to soon! The downstairs thermostat just called for heat to warm up the lounge & kitchen radiators. They’re now hot but problem is - so are the upstairs radiators (where the thermostat controlling the zone is turned off!). We can stop upstairs getting to warm by turning down the TRV’s...

    2 zone CH but 1 zone heats whole house

    It’s a Greenstar 30i ErP NG Combi Thanks for all your contributions. The plumber came round again this morning & was here for over 3 hour’s trying to sort it all out. Having pulled up the flooring in the boiler room, he said the return pipe was incorrectly plumbed in & sending hot water...

    2 zone CH but 1 zone heats whole house

    2 zone CH but 1 zone heats whole house

    Thanks Scott - I took a photo yesterday (when the downstairs thermostat was calling for heat). As you may be able to make out - one of the motorised valves is on A & the other on B - so I didn’t think this was the problem. But could there be something going wrong inside the unit itself that I...

    2 zone CH but 1 zone heats whole house

    I’d really appreciate some advice. We moved into a new build 3 story town house last Monday. It’s got a Worcester boiler & 2 wireless thermostats (one by the front door, the other on the first floor landing). When the downstairs thermostat asks for heat (to warm up the kitchen & lounge) every...
