If you heat your home with electric baseboards, or you have a heating system that runs off of propane or fuel oil, you should consider installing an air source heat pump (ASHP). Because the ASHP moves heat rather than generating it, they are often 2-3 times more efficient than conventional electric-heating systems and also much cheaper to operate than fuel-oil and propane systems. They are also more efficient than other types of air-conditioning systems, providing additional savings during the summer.
