Baxi Potterton Review

I bought a flat in a block where all flats have Potterton Powermax HE boilers and I took out a service insurance with Potterton recently. They tell me I need the flue junction changed plus I booked a boiler service, as offered in the service contract. I made an appointment. I wasted 5 hours waiting the first time – no show. The second appointment, the engineer came and took one look at the new flue inspection hatches and left, saying they were too small. According to Gas Safe Register and Health and Safety Executive (gov site) there is no legal requirement on size. Mine are around 200mm x 150mm but the Potterton service engineer said my correctly fitted hatches had to be 300mm x 300mm. I suspect he was simply trying to get out of doing the job. I would never buy a Potterton boiler again, had I the choice, as the backup service is so poor, never mind the cost of waiting for half hours at a time to get through on the phone at 10p per minute. Sad for British industry.
