i have been asked to look into a boiler system that blows the 3a main fuse in the spur occasionally ie 4months apart then three fuses in a row
the system contains 4 zone valves controlling 2 hot water cylinders with individual cyl stats central heating via room stat and under floor heating with 5 manifold heads & dedicated pump and zone valve controlled via two roomstats. roomstat 1 that controls the zone valve and pump and 1 room manifold heads and roomstat 2 stat that only controls room 2 manifold heads and will not fire the boilers, UFH zone valve and pump without roomstat 1 in operation
two boilers connected in parallel and have internal pumps
i have checked the connections and they appear to be correct could this be a problem with sticking pump or valve causing overload has any 1 encouterd this type of problem before
