Hello everyone
just to update you all, the BG eng came round to say that the heat echanger should be changed. This could cost about £600 to mend and repair as I am not on a contract with them.
Called an independent engineer. He had worked for BG for 13 yrs previously. The unit had its white cover off and he started to check the components.
He cleaned one of the electrodes and the boiler fired up! So, we have a warm house now ;-)
There is sign of rust, he recommended to get a service done in Sept. (before winter). Other than that, he charged £65 for the call out and I will be calling him back.
Cheers!
