These are low-cost heat pumps from the German manufacturer Michl, which set new standards in price and performance. Every year, they take over heating in several buildings, which are characterized by being able to be installed without much effort during assembly. Almost all Michl heat pumps have a built-in circulation pump for water circulation, which can be easily connected to your existing heating system. The electronic control system automatically controls the operation and can adjust the parameters. Compressors of known manufacturers (Copeland and Panasonic) are used in each heat pump.
