We had a customer who called that was getting heat from their second floor radiators, even with the thermostat turned to "OFF", making the room too hot. It only took a short inspection to diagnose the problem as "Gravity Feed Heating." The boiler did not have "Flocheck" valves installed that are designed to prevent hot water rising through the pipes, and the cold water flowing down the return loop due to gravity when the thermostat is not "calling" for heat, with the radiators staying hot in the process. A couple of Flocheck valves later, and the boiler was operating more efficiently, and the homeowner was more comfortable. If you have problems with keeping your home comfortably heated, or with excessive energy bills, we can help.
