Yes, they are open!!!

If all other rads are turned off no these do not work. The pipes below get warm but not too hot to hold (when all other rads off) The pipes were cold when the engineer was tapping the pin and then all off a sudden they came on. All other pins seem to be exactly the same as the ‘stuck ones’...

Pins are sticking up and they are what I describe as spongy (going up and down if I push down with my thumb or flat side of a screwdriver) Radiator water is clear, and they have a decent pressure when opened. I live in a bungalow so no upstairs. All other rads in perfect working order...

When all the other radiators were off these two did not heat up. The pipes though on these two rads did get warmer. I am not smashing the pin with the hammer, I am using it to bounce it up and down to free it up. I have put some WD40 into the pin hole hoping these might free them up a bit.

I moved in to a new bungalow a few weeks ago. I put my heating on for the first time at the weekend I noticed that two radiators were not getting hot. My first thought the TRV’s must be sticking as the system is not even a year old. I removed the head of the Thermostatic Radiator Valves and...

Yeah I brought a Wilo Gold RS50 pump. Unfortunately I cannot just change the motor part over and have to replace the whole pump. As with all things Powermax, it’s so poorly designed that I can’t get the big spanner inside it to remove the unions unless I take off the side panel. Which is...

I have a Powermax 155 Boiler and had a few problems with it recently. My latest breakdown is the CH pump has stopped working. I managed to get it going for a few weeks by every few days removing the main part with the allen key and spinning the impellor to get it started again. Yesterday...

Right, I removed the CH pump cleaned it all up put it back, and then put the speed up to 3. This seems to have done the trick and I now have heating again... Hopefully this is the end of my troubles, Thanks for everyones help on this.

Tony, Thanks for your help. I will do the pump test as soon as I home, I have now found the FAQ's on this section. Cheers again !

I am definitely getting hot water, this morning the boiler fired up like it would do normally. But the radiators are not getting hot at all. I released the screw on the CH pump and I got a trickle of hot water coming out.. What is the white cap on top of the CH pump ? Does this control...

Yeah I drained it the other day but its been fine since the weekend. All I did was as you said pressed the manual restart and it worked fine. Are you saying vent the CH pump ? How would I do that ? My water is very hot so its just the heating that isnt working. Opened the screw of...

Sorry 155. The CH pump is making a small noise hard to describe but like there is a small air leak or maybe when a innertube has a puncture and its in water.

After having boiler serviced last Sept 09-I have had countless problems with this dam unit ! Amazing I didnt service it for 3 years no problems and now its constant ! My latest problem is that my boiler wont start. The lights are on the timer, the pipes in the boiler are very hot as...

Perfect ! All working now, thanks for your help.

Can anyone help please ? This morning I drained my system to replace a thermostatic valve. I then put the ball cock down to refill the tank, bled the radiators whilst they were refilling... But I am certain I made mistake having the boiler on whilst it was refilling. Heat was coming out...

Thanks I will give it a try !

I have a Danfoss Randall RAS-D thermostatic valve which I cant remove. I need to do this as I have a stuck TVR. I have looked on the danfoss tech sheet but it doesnt actually tell you how to remove the head of the valve to get to the TVR !! Not sure whether it comes off by the black...
