we have a Vulcan Autostat boiler about 40 yrs old.
hot water working fine, but when we put the Potterton control onto heating and water Constant, the rads all get hot then go lukewarm after approx. 30mins.
it's been suggested that it might be the triple valve! can anyone shed any light as to whether this might be the problem and if so, where the triple valve is located.
Many thanks
Tracy
