I am a damaged pipe on my CH system, this has occured as i installed new rads last winter that were doubles rather than singles, hence the supply pipe to the rad has to be further from the wall. There wasn't really enough play in the pipe to do this but i managed, the strain was obviously too...

Hi Guys, I have a Potterton Puma 80 Combi which is presently switched off as i am doing some work on my rads. I have a damaged pipe (seperate thread) so at the minute this pipe is open to the air (i.e. not fastened to a rad or capped off). This may be a stupid question but i want to be...

thanks for that i will give it a try today

Hi, on my Potterton Puma 80 what pressure should the expansion vessel be at? What effect does increasing/decreasing that pressure have on the CH. I have a couple of Lockshields that leak when fully/almost closed, to balance the system i need them almost closed. Can they be serviced whilst in...

Any more ideas?

I'm not sure why or how i lost the pressure but i did. I turned off the HW outlet at the base of the boiler, was that correct? If i was to try heating the diverter valve what result would i be looking for? Where is the diverter valve? Cheers

Right, i have given that a try and it didn't appear to make a difference all that happened was i lost a lot of pressure and the rads stayed the same. I repressurised but it made no difference. Any other ideas? As original post am i doing something wrong when bleeding the pump?

thanks i'll gove that a try.

Hi Guys, I have been posting and researching on here for some time now trying to get to the bottom of my central heating dilemna. I have also had paid professionals in to no avail. I have the above mentioned combi running 8 rads (4 up & 4 down). HW system is excellent but CH is pitiful...

My Potterton Puma Combi has recently started tripping out. If you don't use any hot water for a few hours the boiler trips out and the red light comes on and the tap just runs cold, as soon as you reset you can get hot water from the tap. It is fine once in use, i.e. will fill a bath with hot...

Anybody?

Hi Guys, I have a Rangemaster 55 Leisure oven. It has recently developed a problem were the oven door sticks shut, i say shut but it is actually slightly ajar so that heat escapes though still on the latch. With plenty of jiggling, waggling and swearing it will open, though sometimes you have to...

These guys aren't answering my mails any idea whether it is compatible with my boiler?

Thanks for all that info, i think to be doubly sure i will be asking the manufacturers of both the thermostat and the boiler for their recommended installation criteria.

that looks good, thanks for that. I have mailed them to check compatability. Cheers.

I want it so that i can have a more active control over the system. i have finally got my system so that all the rads actually work but they take forever to heat up. I would like to have the system on at a reduced temp through the day while we are out at work, etc and warmer through the evening...

Further to my previous thread, it would seem that i need to swap my room stat for a programmable one. Problem is my system doesn't have a room stat. how simple is it to add one? Which one(s) should i be looking at? The system is a Potterton 80 Puma Combi. Cheers.

My system has no room stat at all, how easy is it to add one and has anyone any recommendations for one that is suitable?

Hi Guys, i have a potterton puma combi feeding 8 rads (4 up, 4 down). I live in a mid terrace that gets flipping freezing without the heating on. Its Double-Glazed (brand new) and has 10" of new loft insulation. Would you expect that it would be cheaper to leave the heating on 24 hours a day...

I chopped out the offending T-piece and cock. Replaced it with a compression fitting T-piece 22mm x 22mm x 1/2" and screwed a 1/2" cock to it, that way any trouble in the future i can just unscrew it and replace. Thanks for the help Guys.
