The Joule high gain buffer and cylinder combined is the unplumbed cylinder used in manufacturing and assembling the SmartPlumb range of pre plumbed heat pump cylinders. The buffer tank is located at the bottom of the tank and the cylinder is above. With 4 direct connections into the buffer tank it is ideally used with a heat pump. The coil in the cylinder is sufficiently large enough to work with both air source and ground source heat pumps. There is a direct connection at the bottom of the cylinder to be connected to a filling loop (not included) and connected into the heating system pipework.
