Heat Pumps

Man installing heat pump

A cold climate air source heat pump (ccASHP) can help you save energy and money when it’s well-sited and used as directed.

Cold climate heat pumps are highly efficient systems and provide both heating and cooling through the same system. For an introduction to heat pumps, watch our webinar presentation.

What is a cold climate air source heat pump?

Unlike traditional heating systems that burn fuel to generate heat, a heat pump moves heat into or out of a building or space using electricity. This transfer of heat, rather than combustion, makes heat pumps a highly efficient option for heating or cooling your home.

The best type of heat pumps for New England are cold climate air source heat pumps (ccASHPs). The ccASHPs can heat efficiently even when temperatures dip below freezing, and they cool more efficiently than conventional air conditioning systems.

How a heat pump works

Who should install a heat pump?

Heat pumps benefit some households more than others. There are many factors that determine whether installing a heat pump makes sense, including a home’s layout, the home’s current heating system, a home’s energy usage, and whether or not the home uses air conditioning. Heat pumps are most often used as a supplemental source of heating and cooling and are not a replacement for your central system.

Heat pumps run on electricity, so to figure out if one is affordable for you, you may compare the projected reduction of your current heating fuel to the projected increase in your electricity usage. If you are replacing an older air conditioner, you may also factor in the change in kilowatts needed to keep you comfortable in summer.

New rebates

Those in Rhode Island who heat with oil, propane, or electricity now have greater incentives to switch to heat pumps through a large rebate offered by the state’s efficiency program, EnergyWise. The size of the rebate depends on the size of the system, but Energy Wise expects most rebates to be around $2,000. Learn more about this at nationalgridus.com/ri-mini-split-heat-pump.

And in Massachusetts, those who heat with gas now have a greater heat pump incentive through Mass Clean Energy Center. The “Whole-Home Air-Source Heat Pump Pilot” incentive starts at $2,500, with additional funds for moderate- and low-income households.

Heat pump benefits

One system for home heating and cooling

ccASHPs provide both heating and cooling through the same system. In homes with more than one indoor unit spread out across the house, homeowners can have direct control over the temperature in various parts of their homes.

Energy bill savings

ccASHPs are highly efficient systems and can save homeowners money on both their heating and cooling bills. ccASHPs can provide significant savings over electric resistance or propane heat and are significantly more efficient than conventional air conditioning systems as well. Depending on what you use to heat your home, ccASHPs can pay themselves back in a matter of years.

High efficiency, lower emissions

High-efficiency ccASHPs can help you and your family reduce your greenhouse gas emissions. Significantly lower energy usage in the winter and summer will contribute to reducing your carbon footprint. Of course, if you green 100% of your electricity through our Green Powered program, then there are no emissions when you use ccASHPs!

Quiet systems

If you're used to hearing radiators creak in the winter and using loud window air conditioning units to cool off in the summer, ccASHPs will be noticeably quieter while still providing reliable heating and cooling.

Air quality and safety

ccASHPs filter and dehumidify air, improving indoor air quality and comfort.

How to get a heat pump

Heat pumps are most likely to be cost-effective if you currently heat with electricity or propane. If you heat with oil, heat pumps may be a good supplemental heating system for all but the coldest days of winter. If you currently heat with natural gas, heat pumps may be a good supplemental heating system for sections of your home that are not currently getting sufficient heat from your gas system (i.e. renovations to basement, attic, or additions that were not factored into the sizing of your heating and cooling system).
