I'm having a bit of a prob with my central heating and wonder if anyone has any ideas.
The boiler is a 6 year old Potterton Suprima 40L and here's an overview of the prob:
If I switch on the central heating, the boiler doesn't light.
If I switch on the hot water the boiler lights straight away.
Once the boiler has been lit by the hot water, if I then switch on the central heating, it works fine and the radiators heat up.
Once the hot water tank's got to the correct temp, the hot water goes off and so then does the heating.
I have to admit that I haven't a clue, so I'd appreciate it if anyone has any suggestions. Thanks for taking the time to read this post, and apologies if I haven't given enough information.
