    Have removed the cold valve easy enough, but the hot valve will not unscrew, have used a spanner and mole grips, but both start sliding and starting to damage the nut surface, is it possible that the hot tap valve unscrews the opposite way ? I assumed both would be anti clockwise to unscrew...

    How long do honeywell two port motorised valves last?

    Ours are lasting between a year and two years and then I have to replace. Is this normal or should I be investigating our central heating system to find out why? Which motorised valves do you recommend I use?

    How do I shut off a bathroom radiator with angles valves?

    My bathroom radiator is very hot in a small room and I would like to shut it off but can’t work out how. There are two valves one at each side at the bottom with a small prong sticking out of each one. I don’t know what the difference is between them or even if that is what I have to turn or how!

    I have a house with 15 rads in it. In a bedroom upstairs I have a rad that isn't heating up. This rad was moved about 5 years ago with 1/2inch plastic pipe to new location in the same room but was never turned on. Tonight I tried to blead it but then removed the rad, emptied it and when off...

    UFH must valves open before pump runs?

    The (rather sparse) manual with the controller that was supplied with my UFH (Hettaj describes the start sequence as - when demanded by the stat - valves open then pump runs. As the programmability of the stat is very basic, I’d like to replace it with a smart controller the same as I use on...

    Are Bulldog TRV valves interchangeable?

    Hi All, I have a number of Bulldog TRVs installed to my radiators (15mm pipe) and most have snapped or broken. :( I would like to replace just the TRV head (not the valve), so that I don't have to drain the rads.

    Cause of intermittent noise from pump and zone valves

    Open vented fully pumped oil fired system. Works well but occasionally (every few days or do) loud throbbing noise from pipes directly above boiler. Goes away if system switched off and then immediately on again. New pump and no benefit from replacing zone valves. Any ideas gratefully received

    Flow rates through 2 and 3 port valves.

    Yes it me again with another question. I keep reading that one will get a better flow rate in an S plan than in a Y plan. Now I can see that being valid if both heating and hot water are called for but if only one surely the flow rate will be the same for both plans? Finally are there any makes...

    Automatic bypass and radiator thermostatic valves

I have a few queries that may be obvious but not to me as old system did not have an automatic bypass. [1] When it comes in it is shunting some of the hot water, will this...
