    DHW heat pumps

    DHW heat pumps utilise free environmental energy for DHW heating. These systems draw heat from indoor air, from basement rooms for example. And the initial outlay is affordable too.

    Independence: DHW heat pumps are a first step towards energy provision based on renewables

    Where DHW heating from renewable sources is concerned, the DHW heat pump offers a quick and convenient solution. Basements in particular are often heated passively and unintentionally, whether by a boiler or by electrical appliances that give off a lot of heat. Rather than allowing it to go to waste, DHW heat pumps reclaim this energy. Up to 70 % of the energy required for DHW heating can be taken from recirculation air. An entire detached house can be supplied with domestic hot water by feeding the yielded heat into the integral cylinder.

    All DHW heat pumps

    Affordable to buy – easy to install

    A compact version of the DHW heat pump can be commissioned with minimum installation effort. The fully wired appliance simply has to be connected to the water pipes.
    Equipped with a suitable fan, the DHW heat pump simply draws in warm ambient air and extracts latent heat from it. This is then used to heat the domestic hot water.
    STIEBEL ELTRON offers a suitable solution for virtually any demand or installation site.

    Efficiency: Heat recovery from the ambient air at the installation site

    WWK 220/300 electronic compact appliances are fully wired DHW heat pumps for domestic hot water heating. They are available with integral cylinder in two sizes and come in an attractive design. These highly efficient heat pumps, with optimally insulated cylinder, achieve excellent output values. The high level of operating convenience offered by the control unit with LCD provides the finishing touch. Information such as the currently available amount of mixed water at +40 °C can be called up instantly. In heat pump only mode, water temperatures of up to +65 °C can be achieved. The exact temperature required can be variably selected.

    These compact appliances are designed to supply several draw-off points. The high quality equipment includes a maintenance-free impressed current anode, which eliminates the costs for anode testing, which would otherwise be required. External signal transmitters can be integrated via the built-in contact input, for example a photovoltaic system to provide solar power generated on site* or, if necessary and where possible, an economy tariff signal.

    Flexibility: hot water from outdoor air for energy management solutions

    The models of the WWK 221/301 electronic series combine all the benefits of the WWK 200/300 electronic but also feature an air duct for the intake of outdoor air or waste heat from an adjacent room. There are two cylinder sizes available in an attractive design.

    In this model too, external signal transmitters can be integrated via the built-in contact input, for example a photovoltaic system to provide solar power generated on site* or, if necessary and where possible, an economy tariff signal.
