Last winter, I replaced our worn-out heating pump, but the downstairs radiators have not been heating up properly ever since.
All was well with the system originally, but now half of the radiators downstairs will only warm up if I turn off two of the bedroom radiators. Once the downstairs radiators are hot, I can turn the upstairs ones back on and they all keep warm. Next day, I have to repeat it all. I have fiddled about with the check valves and bled the system repeatedly, but to no real avail.
When I fitted the pump, I bled all of the radiators and the pump itself and have done so again since.
I have a Potterton 60e heating ten radiators ( four upstairs and six down). The pump is Flowmasta 25-50 130. The boiler is upstairs, as is the pump.
Have I simply fitted a pump that is not adequate for the job?
Regards,
James.
