I have a potterton boiler that's around 12 years old.
When it comes on with the timer the radiators get hot but after about an hour
they go cold.
The boiler is giving us plenty of hot water. We have bleed the radiators but they didn't have any air in them.
The boiler comes on and off as it should and if I turn the thermostat up, it
clicks on.
Any ideas why they aren't staying hot?
Thanks
