OK. Thanks for your help Tony. Appreciated. I do have another question if you don't mind. Would 10mm microbore tails from the 15mm underfloor runs be OK to heat a 8000 btu rad in the conservatory, the tail length from the 15mm will be about 4.5m.

Sorry, should have included that. It's an Ideal Icos HE15. I'll open it a small amount, 1 full turn suffice? edit: Although does make me wonder why they don't put an automatic pressure value instead of the manual valve so that it remains shut when it should be shut.

I think it's a 2 port valve from the top of my head. I'll check again tonight when I get in. Am I right is saying a 2 port valve is basically an in/out yet a 3 port value is a T shaped? All upstairs rads have TRV's, all downstairs rads don't, apart from the one I have just replaced and...

Had another good read through the FAQ, and invaluable resource I must say. One thing I have missed which I believe could be (and hopefully is) the issue. I think I have the bypass valve fully opened, so like the FAQ says because of the less limiting path for the water to go, it all travels...

I have tried balancing at no avail and the valves are certainly open. How good a balancing job without pipe thermometers I don't know though. But I am sure in the past I closed off all other rads apart from the problematic one and it still didn't work correctly. It's 10mm microbore...

Hi, I am in the process of having a new conservatory fitted. Part of this process involves moving a small radiator where the doors to the conservatory will be onto a different wall. Now this little rad has been giving me problems for a while. It doesn't heat up fully (or at all...

Just an update just in case others have the same problem. I ordered a new PCB (part no 174486, V9 Orange) from ebay and replaced it myself, wasn't to difficult a job. And after powering it all back up it worked and the boiler was running as normal. Hope this information will help others...

Bump, please help someone or I fear I will have a costly call out since the house is very cold :(

Hi All, Yesterday I had air in one of my radiators, so I emptied the air. I have a sealed system, so as a result of bleeding the rad I had to top up the system to get pressure back. an hour later the HE 15 attached to the system no longer comes on? No status lights or nothing. I have...
