Hi, We are completely flumuxed here. We cannot get our CH or DHW to heat up. We have drained down and flushed out. Our boiler -Pottereton Kingfisher Mf 40-100 RS 100 Gas Council No. 4158901 - fires up, but there isn't even any heat around the boiler, and certainly nothing round the system. I know this could be the pump, but I would have thought there would be some heat at the actual boiler/at the entrance to the pipe leading from it. It is on a Y plan Zone Valve. Hoping someone can help. We shall call in Corgi Registered experts, but not just to do the things we can do.
