water heater in stainless steel, optimally insulated for minimal heat loss. Constructed on a robust frame with durable panels and effective soundproofing for the best possible comfort, all panels are easy to remove to facilitate installation and servicing. PRINCIPLE OF OPERATION The S1256 consists of a heat pump, water heater, immersion heater, circulation pumps and control system. Heat from the heat source (rock, soil or lake) is extracted via a closed brine system, in which a mixture of water and antifreeze circulates. In some cases, the ground water can also be used as a heat source and an intermediate heat exchanger should be used to protect the heat pump. In the heat pump evaporator, brine releases energy to the refrigerant, which is vaporised in order to be compressed. The refrigerant rises in temperature and passes to the condenser, where its energy is released to the heating
The S1256 is NIBE’s most energy- efficient ground- source heat pump.
