Buffer Tank Heating Systems

These tanks are combined with units such as the ground source or air source heat pumps. They are a tank of the heating system water, positioned between the heat source (heat pump), and the rest of the heating system. They allow the heat pump to charge the tank with heat energy, which can be extracted or taken away by the rest of the heating system. These are required with underfloor heating systems when installed with thermostatic control for each zone. Without the buffer tank, the heat pump would come on when a heating requirement is sensed by a thermostat, but then turn off very quickly when that heating requirement has been met. This would cycle the heat pump and reduce the compressors operational life span. Good system design would always ensure the buffer tank is the heating systems neutral point, with all heating either being taken from the buffer tank or supplied to the tank. In other words, a flow and return from the air / ground source heat pump, and a flow and return from the underfloor heating or radiators.
