Heat Pumps

Plug Into Energy Savings

Heat pumps provide an opportunity for customers to save 50% on their home heating bills relative to oil, while at the same time reducing carbon dioxide emissions by about 80%.

In 2013, Bangor Hydro and Maine Public Service offered a Heat Pump Pilot Program that introduced heat pumps to customers and stakeholders. The program was fully subscribed, and the testimonials so strong that the State of Maine is now funding heat pump rebates. The final report on the pilot program is available here: Emera Maine Heat Pump Pilot - Final Report


Why consider a mini-split heat pump?

  • An efficient heat pump can pay for itself through energy savings.
  • It's a clean, comfortable, and convenient supplemental heat source.
  • Heat pumps not only heat, they cool and dehumidify.
  • Customers who heat with heat pumps may qualify for a lower electric heat delivery rate for all electricity used during the heating season. Please remember that while your heat pump is intended to offset your expenses from other fuel sources, your electricity will increase.

Will a heat pump help me reduce my heating cost?

At today's prices, we estimate that using an efficient heat pump to supplement your existing heat source will reduce your overall heating costs. Calculate your energy savings using the Cost of Heating Comparison Calculator on the Efficiency Maine Website.

The money saved each year is expected to be enough to pay for the heat pump in three to five years. Once the heat pump is paid for, those savings go right back into your wallet. The estimated heating cost savings are expected to cover the cost of your heat pump loan. Actual performance will vary site to site, but we expect heat pumps to be a great opportunity for our customers to take control of their energy costs and save.
