Thanks for that. I was hoping someone might have ruled out the 3 way valve and actuator as potential causes, based on my description of the problem. Is it possible to narrow it down to a faulty thermistor or could it still be the valve and/or actuator?

Hi, I have a Glow Worm Energysaver Combi Boiler providing HW and CH. Just recently, the boiler is ignoring the lack of demand from the CH room thermostat and is providing CH all the time the boiler is switched on. I suspected the 3-way valve which has a Honeywell actuator (VC8010 6 SEC, 6 VA...

Hi, I'v just bought a house with a 15 year old Glow Worm energysaver boiler. It has a couple of automatic air vents on the top of the boiler which I am not familiar with. I want to do some work on the CH system which requires a drain down and would like to know what steps are necessary on the...

Tony, Did you read my last comment? I'm not looking for more advice on balancing which was nothing to do with the root problem. The problem was caused by a creased pipe on the flowside from the boiler to the downstairs rads. It was restricting heat flow by at least 50 percent. At least 3 heating...

Well its taken a long time to be able to write the solution to this problem. It has confounded a number of plumbers with the symptoms not to mention some forum contributors. The problem was a creased pipe on the flowside from the boiler to the downstairs rads. There was enough hot water...

Thanks for your advice Ian, Just to clarify, you say that once water flows from the bayonet/hose the pump should have been primed. Is there a way to tell for sure that the pump has been sucessfully primed without actually priming the pump to check? If not, does this mean the pump should...

Hi, This combi boiler has an integral, allbeit conventional, water pump. It also has a mechanism for bleeding air out of the boiler via a plastic tube at the top of the boiler which has a twist type stopper at the end. This Worcester Bosch Greenstar 30SI boiler is in the loft, i.e. at the...

Thanks Neil/John, I have definetely ruled out a balancing problem at a radiator level. I get plenty of heat upstairs but the lock valves on the upstairs rads were already barely open. I closed them all off as much as possible, any more would have stopped them working altogether. I then...

Hi folks, I have been in this house for a year and one radiator in one downsairs room has always performed poorly. The hot/flow side of the radiator inbound pipe is really hot but the rad itself never gets more than luke warm. I have obviously checked for air locks and I have tried...

Thanks for the advice guys, greatly appreciated. Next question coming up...

I have removed several sockets located in stud walls in my 70's house. In one, the mains lead (T&E) earth went only to the earth on the metal box, not the socket itself. On three others, the earth went to the socket and the metal box earth was not used at all. My understanding is that with...

Thanks for that. The FCU is for a wall mounted 400w electric radiator not for an additional socket. Assume distance is still not an issue? All the power circuits are protected by RCD at the fuse box.

I wish to add a switched fused spur off a ring main socket located in a bedroom. I want to place the new socket approximately 600 mm horizontally from the existing socket on a stud wall. The 2.5mm t&e cable will be run under the floor. Are there any regulations that dictate how far the FCU...
