Product detailsThe fully wired WWK 221 electronic DHW heat pump enables efficient DHW provision for several draw-off points in conjunction with the use of renewable energy. The compact appliance can be installed quickly and easily as a recirculation air unit, to make efficient use of existing waste heat, e.g. from freezers, tumble dryers, heating systems or other heat generators. Alternatively, they can also be installed wherever required with a duct connection for utilising outdoor air as a heat source. The variety of air routing options at the appliance, to the side and/or from above (for air routing from "above", the "LUS 221/301" accessory is required), provides great flexibility in terms of positioning and installation in the installation room. The attractively designed, highly efficient heat pump with an optimally insulated cylinder achieves excellent performance values. The high level of operating convenience offered by the control unit with LCD provides the finishing touch. Information such as the amount of mixed water currently available at +40 °C can be called up in an instant. The high quality equipment includes a maintenance-free impressed current anode and an emergency booster heater. The built-in contact input enables the integration of external signal transmitters, for example a photovoltaic system, to utilise solar power generated on site (requires selected inverter), or, where possible, an off-peak tariff signal.
Please ask your local power supply utility or a registered electrician to install appliances that are not fully wired, i.e. ready to plug in. The electrician should also be able to assist you with obtaining the agreement of the respective power supply utility required for the appliance installation.
