We use the NIBE air source heat pump as an element in our BMS systems. The NIBE F2040 is an intelligent and compact inverter controlled air source heat pump which provides optimum savings since the heat pump automatically adapts to the building’s output requirements all year round. The heat pump works down to an outdoor temperature of –20°C and at the same time supplies up to 58°C in supply line temperature. By careful selection of a compatible controller and software Intelligent Immersion allows heating of the building.
