HELP!! Cold Rads
I would be grateful if anyone could give me some advice.
I Recently moved into a new property, and decided to give the central heating a 'full service' the boiler has been serviced and a new pump fitted. all the radiators have been removed and flushed, and are all balanced.
The rads were balanced six weeks ago and have been working fine, until yesterday, the property is a dorma bungalow, with one room upstairs.
3 work fine downstairs, the 1 upstairs works fine and a fourth downstairs gets luke warm, leaving 2 downstairs which are stone cold.
The boiler seems fine as does the pump, I have bled the system with no joy.
Can somebody please advise.
Thankyou in advance.
