    Central heating leak

    I have a leak under my floor but having had 9 plumber visits this year no one has found it. it seams it’s a small leak that must happen when pipes cool and contract.

    Replacing combi boiler central heating pump - fair cost

    Hello, recently my central heating stopped working and an engineer diagnosed the problem as being that the electrical connection point on the heating pump has partially melted, presumably due to the connection being poor.

    Flush gravity fed F&E central heating system

    Forgive me is this is a stupid thought! I'm looking to flush dirty water out of an F&E system. Can I attached a hosepipe to the lowest drain off point and simply drain off water outside without turning off the water supply to the F&E tank? So my thinking is that it may take some time but...

    Warnflow Oil Central Heating Condenser Boiler turning itself on

    Hi, The boiler is coming on when the timer clock is set to off. Because the timer clock is off no motorised valves open and so no heat gets around the house but the radiator nearest the boiler gets hot, (obviously not controlled by the valves). Why would this happen? The control box was...

    Central Heating Pipes

    Hi all, Earlier today I was trying to get a few floorboards up to get access and one of the 15mm pipes came out of its brass tee connector with the ensuing wet face and mad panic that a bar of water can give you. I popped a bucket under the fountain (it was pointing ceiling way) and ran down...
