Heating Working Upstairs But Not Downstairs

A nice simple job for a change, the customer was complaining that the hot water was working fine and the central heating upstairs, but none of the radiators downstairs. The boiler, Potterton Netaheat, was running fine and not making any unusual noises.

Looking in the airing cupboard at the pump, it was very hot and didn't sound as if it was running very quickly. I replaced the pump, and the radiators downstairs were soon working again.
