What Does the PCWU 3.0kW Heat Pump Offer?

The PCWU 3.0kW model is an indoor heat pump designed for domestic hot water (DHW) preparation in residential homes and commercial buildings. Its modular design allows easy connection to an existing water tank, making system modernization quick and efficient. The pump operates efficiently and economically throughout most of the year – down to outdoor temperatures of around -7°C. In the summer, the cooler air expelled by the unit can be used to provide free interior cooling.

Efficient Water Heating with Low Energy Consumption

Despite its compact size, the PCWU 3.0kW pump delivers outstanding heating performance for its class. When combined with a suitably sized tank, it can meet the hot water needs of a family of up to six people. With energy consumption below 800 W, heating 300 liters of water to 45°C costs around 2 PLN per day – up to four times less than traditional electric heaters.

Energy Class A+ – Savings and Sustainability

By utilizing renewable energy sources, the PCWU 3.0kW significantly reduces operating costs. Its top-tier A+ energy efficiency rating also makes it eligible for better subsidies and grants, which are often dependent on the device’s efficiency class.

Flexible Installation – Perfect for Retrofits

The modular design allows connection to both new and existing water tanks. Depending on the tank type (e.g., number of heat exchanger coils), the unit can cooperate with a heating boiler or solar installation. The recommended tank volume ranges between 200–500 liters. The heat pump connects directly to the tank, not its coil.

OPTI-ENER System – Smart Energy Management with PV

The innovative OPTI-ENER (EMS) energy management system from Hewalex ensures maximum use of free solar energy from a PV system. The pump can automatically activate when solar energy is available, leading to real savings. The unit supports the SG Ready standard, enabling integration with smart energy networks and the use of flexible electricity tariffs.
