Lucy’s 1403 sq. ft. home was heated primarily by a forced air natural gas furnace with the main unit in the basement. Lucy also had a space heater in the downstairs bathroom as a source of supplemental heat.

 ​Lucy’s Concerns 

• Difficult to distribute heat upstairs with forced air
• Reducing reliance on fossil fools
• Improving safety and air quality of home

Solutions
• Before adding heat pumps, improved insulation
• 5.3 kW of solar panels installed in her yard
• Installed a ground-source heat pump

Benefits

• With solar array energy production, electricity costs are comparable to costs for heating with natural gas
• Air conditioning in the warmer months
