    How a heat pump works

    The heat pump is a thermodynamic heating system. It can be used to convert environmental energy into heat for your home. The heat, which is drawn from water, the ground, outdoor air or extract air, first passes through an evaporator from whence it is fed, via a condenser, into the heating system.
    Approximately five parts environmental energy and one part electrical energy are provided as heating energy. Electrical energy is required to "pump" the environmental energy, which is at a low level of -20 °C to +35 °C (air), to a temperature level suitable for heating (DHW).

    Energy Label for heating heat pumps

    The top of the ErP label displays the name of the manufacturer (I) and the model designation (II) of the product. The rating system for heating heat pumps categorises them into nine efficiency classes. A++ is the highest energy efficiency class. G denotes appliances with extremely poor values.

    STIEBEL ELTRON products are almost exclusively in the top group. All STIEBEL ELTRON heating heat pumps are already in the top rating category, i.e. classes A to A++.
