Low and medium temperature applications should not be confused with the requirements for low temperature heat pumps. Low temperature heat pumps are specifically designed for low temperature application and are NOT able to deliver heating water with an outlet temperature of 52 °C at an inlet dry (wet) bulb temperature of – 7 °C (– 8 °C) in the reference design conditions for average climate. The seasonal space heating energy efficiency of low temperature heat pumps shall not fall below 125 %. For low- temperature heat pumps, parameters shall be declared for low-temperature application.
For all other heat pumps, the seasonal space heating energy efficiency shall not fall below 110 %. Parameters shall be declared for medium-temperature application. Manufacturers can declare values for low temperature application on a voluntary basis, but there is no requirement attached to this declaration.
