Hi,
I live in a rented flat with a Glowworm Swiftflow 75/80 boiler. We have had several problems with this boiler mostly dure to low pressure. We finally worked out how to increase the pressure and all was fine for a while but we now have another problem.
The pressure guage sits at 0.7 and doesn't change when using hot water. Hot water supply is fine. However when we try to put the Central Heating on the following happens: Pressure guage needle starts quivering madly then rises, the boiler makes a 'whumph' noise like it is firing up, the pressure keeps rising up to 2 and then the pilot light dims and the pressure falls. Once it is below 1 it starts to rise again, reaches 2 and then the pilot light goes out completely. No Central Heating.
Any advice? We're freezing.
