When and how often should you replace the exhaust air heat pump?
Has your exhaust air heat pump stopped working or is the fuse blown? Then it may be time to say goodbye to the pump and invest in a new one. The same applies if you no longer get any heat from it or if the energy consumption is unreasonably high. Service may be the answer, but if the pump is a few years old, it may be good to replace it.
Replacing the compressor can give the heat pump an extra life, but as a rule, the pump has a lifespan of about 15 years, after which it is economically profitable to replace it.
