A customer has a 20 year old Flowmaster heated by a solid fuel Raeburn, the domestic supply is unvented the heating is vented through the built in header tank similar to a combi tank. Two nights ago the tank boiled and overflowed outside, Sparky fitted a new tank stat as it was faulty. Now there is very little domestic hot water, heating side is working. Fine. Any help appreciated.
