Heat pumps can provide cost-effective and energy-efficient heating, cooling and water heating for homes and businesses. While traditional systems burn fuel to create heat, a heat pump instead works by moving heat into or out of a building. Though they require electricity to operate, efficient heat pumps can provide the same amount of heating for a third of the electricity needed for traditional electric heating.
Heat pumps circulate a liquid, called a refrigerant, between an indoor air-handling unit and an outdoor radiator. When heating a building, the heat pump heats the liquid by pressurizing it, pumps it from outdoors inside, and then circulates it through the home or building’s heating system.
After the liquid transfers the heat into the building, it is depressurized and cooled. The liquid then travels to the outdoor radiator, where the ambient temperature warms the refrigerant, and the process begins again.
Heat pumps can also be used to cool buildings through a similar process. In this case, the warm air inside a home or building is cooled by the liquid, which has been depressurized. The refrigerant is then sent outside and pressurized, which heats it up, and the ambient outdoor temperature cools it.
Air-source heat pumps use the temperatures of the outdoor air to heat or cool homes or buildings. Advancements in technology over the past few years have made air-source heat pumps an efficient source of heating and cooling in cold climates like Massachusetts. Models on the market today can operate efficiently even when it is below zero Fahrenheit.
Much like air conditioners, air-source heat pumps can be installed either as central units or split units. Central units utilize a building’s heat distribution system to heat and cool a building and can also be used for water heating. Split units typically provide heating and cooling to just one room of a building, reducing demand on the existing heating system. VRF units are applied products that are typically larger, provide greater control and efficiency, and support a commercial-scale building’s entire heating and cooling demands.
MassCEC provides grants and rebates to support the installation of air-source heat pump systems. Please see our Residential, Business, and Government/Non-Profit Clean Heating and Cooling websites for more details on how to apply for funding.
Economics & Incentives
Efficient heat pumps can reduce heating costs when replacing or supplementing an oil, propane, or electric resistance heating system. In fact, air-source heat pumps can heat your home or building for half to one third the price of traditional electric heating.
Through a partnership with the Department of Energy Resources, MassCEC supports the installation of air-source heat pumps through its Clean Heating and Cooling program.
Why should I consider an air source heat pump?
There are many reasons why heat pumps could be a good fit for your home:
- Energy savings. If you heat with oil, propane, or electric resistance heat, you could save hundreds of dollars a year on your heating bill by installing a heat pump.
- Improved home comfort. Heat pumps filter and dehumidify air, which can improve the air quality and comfort of your home. They’re also quieter than your refrigerator.
- Flexible options. Heat pumps are a flexible technology that can be installed in homes of all shapes and sizes with different needs—whether your home is ready for a new heating or cooling system or you just need some extra heating or cooling for part of your home that’ never comfortable enough.
- Affordable and convenient. Heat pumps are supported by rebates offered by the MassCEC , your utility, MassSave and are eligible for 0% interest financing from the Mass Save HEAT Loan.
- The latest in home heating technology. The new cold climate heat pumps installed through Solarize Mass Newburyport can keep you warm well below 0°F. Gain more control over the comfort of your home by being able to control your heat pump from your smartphone!
- Reduce your carbon footprint. As a clean heating and cooling technology, switching from burning fossil fuels to using a heat pump will help reduce your carbon footprint and dependence on imported fossil fuels.
- High-efficiency cooling. Heat pumps also provide air conditioning and will be less expensive to run than your average window unit or central air conditioning system.
