My wife and I own a Bailey Unicorn II Cadiz fitted with an Alde Heating system which has a fault.

With heating selected to Electric on the lower panel and the heating thermostat set below ambient to allow for hot water in the sytem but no heating sometimes (usually in the middle of the night) the central heating pump starts to run. No heat is produced
but the pump continues to run until the lower panel is set to off.

Any body out there had similar problems? The van is still under warranty but the dealer can't replicate the fault and has no idea whats causing it.
