Hi I have a Gloworm 30CI which has been in the house since we bought it in 2007. I have repaired and replaced the filler cap and the odd o-ring and it's generally given us very good service. It started leaking one day from what seems to be right at the back on the left side of the pump, I have...

I'm looking to create a cupboard around my kitchen combi boiler. Is it safe to cover all 5 sides? Or do the top or bottom have to be left exposed? Also, is there any issue in trying to line the cupboard with some sort of soundproofing material? Thanks for any input.

Awoke this morning to a cold house and a Glowworm Energy 30S boiler showing an F75 error code which would indicate a pressure or pressure sensor issue. When I restart the boiler the pressure shows 0.6b for about 30 seconds before going into error, one video online implied it would show 1.5b as...

Hi, I got a plumber round to change the pipes for 3 radiators to one. They aren't quite in the right place but luckily there is some give so at a stretch we can make it work when we install the radiator. He quoted to do this and install Hive for £160. Seemed like a nice guy until he broke the...

Hi, last night our central heating system seems to have developed a problem. Our boiler is an Ideal Logic 15. It appears that the thermostat is working fine (?) but somehow the boiler thinks there is a constant demand to supply heating. For example, thermostat currently at 20c and the flame...

Hello everyone, My home has a BAXI DUO-TEC COMBI 24 HE. The radiators won't heat up even though the boiler is showing a green light saying they are running. The hot water is still working though. I've tried bleeding radiators and then pressurising the boiler after but I still have the same...
