![]() ![]() How much colder the refrigerant gets than the outside air is what determines its efficiency. To heat air in the wintertime, the heat pump needs to be able to cool down the refrigerant so it’s cooler than the outside air. That’s because it has to work harder to produce heat, meaning it uses more energy. When the outdoor temperature is extremely cold, a heat pump typically becomes less efficient at heating a home. But, like all powered devices, heat pumps will reach a certain maximum efficiency rating, which dwindles in extreme conditions. Heat pumps are necessary in cold weather, as they keep a home warm. Heat pumps are designed to work year-round, meaning they’re both a heating and cooling solution. The refrigerant that absorbed the heat energy evaporates into a gas, which gets compressed and sent outside via the outdoor unit.īoth the heating and cooling modes repeat on a continuous cycle to maintain the desired ambient temperature.The cool air gets circulated throughout the home.The indoor unit fan blows the warm air across a coil containing refrigerant that absorbs the heat, cooling it down.The indoor unit pulls warm air from inside the home into the unit using a fan.The indoor unit circulates the warm air throughout the home via ducts and vents.Īnd here is how a heat pump works in cooling mode:.The indoor unit further heats up the air by condensing the air as a fan blows it across a coil.The heat energy is transferred to the indoor unit via a refrigerant line.The outdoor unit extracts heat from the cold, outdoor air, compressing it to maximize its heat energy.The outdoor unit gets installed in an unobstructed location outside your home, typically in the side or backyard.īelow is how a heat pump works in heating mode: ![]() The indoor unit gets mounted in a central location inside your home, typically toward the ceiling. These all-in-one solutions come with both an indoor and an outdoor unit, each with its unique role depending on the season. It’s an energy-efficient alternative to traditional heating and cooling options like furnaces and air conditioners. How Does a Heat Pump Work?Ī heat pump is a device that provides heating and cooling to an indoor residential space using the principle of heat transfer. We also cover what you need to know about operating a heat pump in either extremely hot or freezing cold temperatures. This guide to heat pumps explains how these devices provide both cooling and heating. Though heat pumps are becoming increasingly popular in new residential homes and as furnace or air conditioning replacements in existing homes, there are still misconceptions about how heat pumps work and what types of climates they’re suitable for. If you’re looking for cost-effective, energy-efficient and low-maintenance ways to heat and cool your home, then a heat pump may be the solution. ![]()
