Turns out the motor on the main boiler upstairs had given up the ghost an was sticking in the on position.
So no matter what the timer said the motor was calling it to fire up.
The original issue was a single radiator that didn't heat.
He changed the valve and the TRV, so I guess was testing it.
However since he walked out with no success the ch has permanently been on.
I have a strange question.
We have a Myson tank, radiators, a Potterton boiler and Honeywell timer.
Recently we had an issue with the central heating. An engineer came it to look at it and when he had finished he walked out and said he had overidden the system.
Now the Central heating is on...
For me the TRV is the myson thermostat and the valve is the radiator section.
The valve looks new and the TRV definitely.
My wife was trying to listen in while the engineer was on the phone and he was saying he hadn't "milked it" whatever than means.
The TRV was replaced today and the pin does move, although I finger the feeling not all the way down, so maybe a trapped washer.
I have given it a fair few "taps" but that hasn't worked.
Shut off all radiators in the house an fully opened both sides of the cold one.
Sadly it didn't warm up.
I have noticed that the pipe that foes to the TRV is hot all the way to the radiator, it seems it just can't get into it.
Any other thoughts?
Cheers
Ok, I assumed it involved more than that. In which case I will give it a go tonight and report any results assume I just turn off the TRV's on all the radiators?
Cheers
I haven't tried that yet no.
Maybe when the weather is slightly warmer I will try it.... Otherwise my wife and kids may kill me for trying to freeze them.
Thanks
indeed both vavles are open.
I removed the TRV completely, and opened up the valve on the other side.
I left it like this for 24hours, but made no difference.
thanks
The previous owners of our house had a conservatory fitted, and added on a radiator to the central heating.
Everywhere i read they say that this extra one steals heat from the one in-line before it, which is the case.
Unfortunately the one before it is the lounge, which makes this room quite...
Many thanks for your quick reply.
I bled the radiator and clear water came out straight away, however i did notice that hotter water came up the pipes. So the theory being that if i carried on bleeding the hot water would make it into the radiator.
However i wasnt sure on the consequences...
Afternoon.
I have a townhouse that is 7 years old. I have had a radiator that had a myson valve that was bust (set permanently off), so hte radiator was always cold. This year i removed the valve to allow the pin to spring up, however the radiator doesnt heat up. All the others in the house do...
