[QUOTE="Geoff1946, post: 495479, member: 28452"] I hope they know what they are doing. My semi-retirement job was maintenance in a care home, where three boilers had been connected together and it gave all sorts of problems. For instance when one boiler shut off it acted as a bypass to the other two, effectively becoming a radiator, but reducing flow in the heating zones. Also multiple pumps, which fed three 'stat controlled zones from the common header suffered from backflow. It was clear from numerous obvious modifications, redundant motorised valves, extra pumps, etc that it had never worked well. During my time the three boilers were reduced to two, but the basic problems I mention persisted. [/QUOTE]
