We have been in our house for 6 months now and have just had the house rewired. During the process of rewiring the electrician managed to cut through a water pipe. At the time the electrician wasn’t aware what pipe it was and switched off the main stop-cock and turned on all the taps including the hot water taps. He then worked out that it was actually one of the central heating pipes, so we closed of the supply to the header tank and drained the central heating system.
The pipe was repaired, the supply to the header tank was re-opened and all radiators were successfully bled and are now working ok. Unfortunately the problem we have now is that we can’t get any hot water unless we use the immersion heater.
Now I’ve read a few posts on here by people that have had similar problems but I’ve not been able to action the solutions due to differences on my system. I’m therefore asking for some advice relevant to my particular system.
This is what I’ve been able to deduce about the system in our house. I believe it is an open vented gravity domestic hot water and pumped central heating system.
We have a Potterton Kingfisher MF CF 60 boiler, with a Randall 3060 timer and a Myson Compact CP53 pump. The “flow” pipe comes out of the boiler and passes through a tee. Horizontally out of the tee the pipe runs to the pump and vertically up through the house to the hot water cylinder. The boiler also has connections for return pumped and return gravity.
The hot water cylinder has an input and an output for the flow and return and a cold water feed and a hot water output. I can find no bleed valves on the hot water circuit. The hot water output does have a pipe that goes off into the chimney breast that I believe is probably some sort of vent? There is also no thermostat or timer connected to the cylinder.
In the loft we have two tanks, the big cold water storage tank and the header tank.
So in summary, we have central heating and flow of water through the hot taps and can get hot water if we use the immersion heater but no hot water when using the boiler to heat hot water.
I think that’s about it, I’m no plumber and I wasn’t in the house when the system was installed so I hope I’ve explained the problem in enough detail. Any advice would be appreciated.
Thank you
