The North Parish Climate Justice Group along with the North Andover Historical Society present “Electrify your Home” on Tuesday, May 21, at 7 pm. Chris Spychalski and Gary Martin of Heat Smart Alliance will present recommendations for reducing or eliminating the use of fossil fuels in your home. They will cover information about converting to an electric HVAC system using either air or water source heat pumps. Both types of heat pump can be used with either hot air or hot water systems and may be able to use existing radiators. Heat pumps have the added bonus of providing air conditioning.
