Baxi Auriga Mid Temperature Air Source Heat Pump
The Baxi Auriga air to water Air Source Heat Pump (ASHP) is perfect for commercial applications in both fully electric and hybrid heating systems with a high SCOP up to 4.83.
Generating up to 60°C hot water temperature, it is available from 20kW to 320kW when used in cascade. The mid-temperature monobloc design, is a self-contained heat generator, extracting renewable heat from the atmosphere and amplifying it using R32 refrigerant to provide a low cost running solution.
Wherever you need heating or indirect hot water production, our heat pumps are a high-performing, efficient choice. Available to quote today.
