We have a problem with our Central Heating that even a Corgi certified Engineer does not know how to fix it.
We have Potterton NetaHeat 80 boiler.
1. The room thermostat is set to 25 degrees
2. The Water tank thermostat is set to 60 degrees
3. The Honewell CH control is set to Continuous Heating and Water
The boiler comes on. The radiators start to warm up. The water gets very very hot and the CH boiler shuts down.
If we up the the Water tank thermonstat temperature then the CH boiler comes on again and then stops again when the water reaches the temprature set on the Water tank.
The engineer has changed the fan on the boiler, water pump, honeywell 3 -way switch in the airing cupboard and the thermostat on the water tank (Total cost around £500) but the heating is still not working.
Any help would be appreciated to solve the problem.
Thank you.
Regards,
Jo
