ASHP Optimised 15kW LTHW Hot Water Fan Heater for Low Temperature Heating Systems

The Powrmatic WX-1.1-EC is a low temperature hot water (LTHW) fan heater specifically engineered for compatibility with Air Source Heat Pump systems and modern low temperature hydronic installations. Delivering up to 15kW of heating performance with airflow of 2000m³/h, the unit provides efficient and responsive space heating in commercial and industrial environments.

Designed to operate effectively at reduced water temperatures, the WX-1.1-EC offers enhanced performance in heat pump applications where traditional high-temperature unit heaters would experience output loss. The integrated EC motor ensures smooth speed control and reduced electrical consumption, providing improved energy efficiency compared to conventional AC motor alternatives.
