SAHP 300 - Solar-Assisted Heat Pump

SAHP 300

The SAHP300 is the solution for larger homes and commercial units, combining innovative solar assisted heat pump technology with an ERP-A rated, 300 litre stainless steel cylinder.The SAHP300 is the all in one solution to your hot water heating requirements. The SAHP300 offers either direct, indirect, unvented, vented cylinder, suitable for every installation. This hot water heating and storage system has been tested to UL standards and utilises our already proven technologies.

Relying on the same thermodynamic principles as the existing Solar Assisted Heat Pump range, the SAHP300 transfers this energy to water within its casing, to efficiently and effectively handle the water heating. The SAHP300 is sold with an improved controller that offers connectivity to existing solar PV inverters.
