The Qvantum QE is an energy efficient exhaust air heat pump, providing heating, cooling, ventilation, and hot water. The heat pump is inverter controlled and has an integrated buffer tank. The exhaust 
air unit extracts energy from the outgoing ventilation air. The inverter control automatically adjusts to the comfort demands of the home, thus minimising energy consumption. Domestic hot water is produced instantaneously with heat from the integrated buffer tank. The buffer tank can also be used to avoid energy peak prices for both heating and hot water. The QE heat pump is available in 4 kW and 6 kW output and supports both single- and three phase connections. The heat pump can also provide cooling. The compact and flexible design of the QE heat pump makes it easy 
to install, not only in newly build homes, but also as an upgrade for existing exhaust air heat pumps. The heat pump is well suited to replace gas boilers in low temperature systems. The heat pump is easy to operate and has a low noise level, which makes it an asset to any home..
