The generated heat output is outlet via an integrated stainless steel heat exchanger (external circulating pump required). The cooled air can be blown out directly in the installation room or outdoors via ducts. Heat output approx 2 kW with an exhaust air temperature of 25 °C and a heating water outlet temperature of 35 °C.
