Frequently Asked Questions

What kW size heat pump do I need for a 96 m² (1033 sq ft) house?

For a 96 m² (1033 sq ft) building with Standard Double-Glazed Insulation (55 W/m² Base) in US North & Canada Cold (-18°C Design, NY/IL/MI/ON), the peak space heating load is 6.86 kW (71.5 W/m²). Including domestic hot water allowance, a 7.5 kW (25,591 BTU/h / 2.13 Ton) heat pump is recommended.

How many kWh of electricity does a 7.5 kW heat pump use per year?

With a Seasonal Coefficient of Performance (SCOP) of 3.5 over 2400 full-load equivalent heating hours, the heat pump consumes approximately 4,704 kWh of electricity per year to deliver 16,464 kWh of heat — saving 11,760 kWh/year compared to direct electric radiators.
