How Does a
Heat Pump Work?

  • You can use a heat pump as the sole heating and cooling appliance in your home, or you can combine a heat pump with an existing heating system. Many homes with existing ductwork for forced-air HVAC systems can be adapted to heat pumps. Ductless heat pump systems, called mini-splits, can provide heating and cooling in a home without ducts, or add climate control to rooms that the main system doesn’t reach.

  • Living with a heat pump is a bit different from using a traditional heating system. A modern heat pump is most efficient when your thermostat is set at a constant temperature—it actually saves energy if you don’t turn it down overnight. They also blow cooler air than furnaces and run almost constantly at a low level, rather than blasting heat for short periods throughout the day. Good insulation and air sealing of your home and duct system are important regardless of how you heat your home, but they’re even more beneficial with heat pumps.  

With the right heat pump and system design for your home and regional climate, a backup heating system should not be necessary.

If you Are Considering Furnace Replacement or have major repairs
Consider a heat pump

Heat pumps don’t generate heat—they transfer it.

A gas furnace generates heat by burning combustible fuel, such as gas or propane, while an electric furnace generates heat in much the same manner that a hairdryer would, by blowing air over a hot element.

A heat pump works on a different thermodynamic principle: It draws heat from the outdoors (even if it’s cold outside) and transfers that heat to your home’s interior. So while a heat pump will not generate heat, it is able to absorb heat via pressurized refrigerant lines and then release that heat into your home.

Heat pumps can heat
and cool your home

While a furnace is designed to generate only heat, a heat pump warms your home in winter and cools it during the summer months. During hot weather, a heat pump operates in an identical manner to an air conditioner, by reversing the pressure and the flow of refrigerant through its coils. This can be a big benefit for homeowners who would otherwise need to purchase a separate air conditioner.

Furnaces cost more
to operate than heat pumps

Generating heat requires a lot of fuel, but because a heat pump doesn’t generate heat, it only needs enough electricity to circulate the refrigerant through its pressurized lines. A heat pump uses much less energy than an electric or gas furnace. While exact operating costs depend on the climate where you live, the unit’s efficiency, and local utility costs, for a single winter season, heating costs run an average of $1,550 for a propane furnace, $850 for a natural gas furnace, $900 for an electric furnace, and just $500 for a heat pump. Since heat pumps work on the same principle as air conditioners during the summer months, the costs to cool your home with either will run about the same—$300 or more, depending on your climate.

Heat pumps
require less space

Furnaces, which are typically installed indoors, can take up a lot of square footage because manufacturers and local building codes often require a 30-inch clearance on all sides for fire safety purposes. The compressor part of a heat pump, which is located outdoors but close to the house—in a similar manner to an air conditioner—requires a minimum 24-inch clearance around its outdoor unit. Since a heat pump’s indoor air handler does not use combustible fuel or generate its own heat, it doesn’t need additional safety clearance. Depending on the type of air handler that comes with your heat pump, you might be able to mount it high on the wall so the unit doesn’t encroach on any floor space.

about heat pumps

“Heat pumps use small amounts of electricity to move heat from one space to another.” – (c) Forbes

“According to the Department of Energy, heat pumps use about 50% less energy than furnaces or natural gas systems and can help you cut energy and utility bills. ” – (c) Modernize.com

“The more people take advantage of the heat pump tax credit over the coming decade, the better for cutting emissions.” – (c) Cleantechnica
