Energy efficient heating and cooling
A large heating demand requires an efficient heating system. The robust WPL 47/57 air source heat pump from STIEBEL ELTRON is the perfect hydronic heating solution for apartment blocks or commercial buildings. The WPL harvests energy from the air to achieve flow temperatures of up to 60°C, suitable for both in-slab and radiator heating. Engineered for Australian conditions, the system utilises an efficient defrost function that allows for operation in temperatures as low as -20°C.
