No hot water
Hi
I have a 15 year old Boilermate 3 that I have replaced the plate heat exchanger in about 6 year ago and a pcb control board about 2 years ago. Today I fitted a new towel heater radiator and the DHW has stopped working. The water runs hot for about 30 seconds then goes cold. The DHW pump is coming on as I can feel it gently vibrating.
When I removed the old radiator I did drain it first and obviously filled the new one today.
I wondered if the storage tank hadn't filled enough although I don't think one small radiator would drop the water level much. So I investigated the header tank and found a useless ball valve which was completely stuck closed. So I topped the header tank up with a jug without benefit, the header was half full, well over the storage tank inlet.
The heating works fine.
Any trouble shooting suggestions?
Best wishes
Phil
