Central heating radiator

[fittiered]

Needs bled every few days! Only the one radiator upstairs the rest seem ok. We had a new condenser gas boiler fitted last September. Thanks for any advice.

Radiators are best bled when the heating is off.

Once bled refill via the filling loop at the boiler from 1 bar or up to 1-5 bar. You will see this bar clock on the boiler or just under it.

When filled wait untill the radiators have cooled as the system contracts that will then show up any small leaks on any radiator valves a likely sorce for any leaks ..

This is often the case for for having to bleed radiators.
Did you have any problem with air in radiators before.
