Hi all,
I am hoping someone can give me some advice - I have a strange problem with some of my radiators being cold.
I rented out my cottage while working away, and the tenant decided to turn off all the radiators at the valve. The boiler (gas gravity system running 7 radiators) I know is fine, as it just went through a landlord annual safety check and service right before the tenant moved out. However, when we switched the boiler back on and turned the valves back on, four of the radiators heated up fine, but three were stone cold.
There doesn't appear to be any air in the system, and the whole radiator is cold, so it's not that they need bleeding.
It's been suggested that they might need desludging, but someone else has since suggested that a sludge problem would give a similar effect to air in the system and the radiators would be partially warm.
If you push in the valve you can hear the flow change, so there does appear to be flow. Also the pipe going to each radiator is hot.
I know a bit about plumbing but not enough to work this one out - I am totally baffled. Any suggestions would be really welcome.
Many thanks
Lindsey
