5. This is how your heat pump works This is how your heat pump works The heat pump collects stored solar energy The heat pump HT Plus has been manufactured for easy and reliable use as well as to provide your house with inexpensive and environment friendly heating The easiest way to describe how a heat pump works is to say it works like a refrigerator however the other way round In a refrigerator heat is moved from the inside to the outside In a heat pump heat stored in the ground rock or water is moved into the house The heat pump reclaims the stored solar energy which is then led into the house via a hose The temperature is then increased in the heat pump and the heat is distributed to the house s heating system Bedrock heat Ground heat Lake water heat Technology in and around the heat pump ra Note x The heat pump consists of four main parts Boiling point in relation to the pressure 1 Evaporator The boiling point of different liquids Evaporates the refrigerant to gas and at the same time transfers the varies with pressure the higher the heat from the heat transfer fluid to the refrigerant circuit pressure the higher the boiling point 2 Condenser For example water boils at 100 C Condenses the gas to fluid again and transfers the heat to the heating at normal pressure Double the pres sure and water boils at 120 C Half the pressure and water then boils at 80 C The refrigerant in the heat pump
