    Discovered, on getting an engineer in to fix what I'd thought was probably a minor fault preventing the boiler from working, that it has had to be condemned (and yes, justifiably - you should see the insides! Ye gods ...). The house (probably 1000-odd sq. ft.) is a fairly typical 3-bed layout...

When I switch on my hot tap, am I right in assuming that the hot water will be delivered solely to my hot tap? even though the path of the hot water may pass through multiple tee’s on the way (which will have cooled water at their other connections). I expect the...

    The furthest radiator from my boiler is a 160cm x 50cm Type 22 in my living room. It has always been set as the bypass, but this isn't ideal. The living room can overheat, whilst the kitchen is cold. The obvious answer would be to set a lower temperature on the TRV in the living room, but this...

    Can I turn down the central heating temperature on combi boiler if I have TRVs?

    Hi, I've got a combi boiler. I was thinking of turning down the temperature of the heating on the boiler (i.e. on the boiler itself not the temperature on the thermostat). Reading up on this it sounds like setting this as low as possible is the best option in terms of reducing gas usage - to try...
