Hi,
We've recently moved into a house with an old glowworm boiler.
We had problems with the central heating at the start - some of the upstairs radiators weren't getting hot. An engineer fitted a new pump and that problem has been solved. The upstairs radiators now all get hot.
However, we've now developed another problem.
When the heating comes on, all the radiators get hot - upstairs and downstairs.
However, after a few hours, the downstairs radiators go cold. The upstairs ones remain hot. The central heating is turned on and boiler is still firing up.
None of the radiators have thermostatic values, so that's not the cause of the problem.
Any one any ideas please?
Thanks.
