Most Efficient Heat Pump by WaterFurnace

WaterFurnace International, Inc., a manufacturer of geothermal and water-source heat pumps, just launched what the company is calling the “world’s most energy-efficient heat pump,” according to a press release.

The 7 Series exceeds Energy Star requirements and qualifies for a 30% federal tax credit, said WaterFurnace. The heating and cooling system also comes with a laundry list of other design features: integration with automation and energy monitoring systems, online remote monitoring and control, quiet performance with a lower compressor speed, advanced hot water generation, and a port for service and diagnostics that doesn’t require opening the unit.  700A11 uses a soft-start variable capacity compressor, variable speed ECM blower, and variable speed loop pump to scale output as needed.
