Although there are numerous HVAC systems available to install in your home to provide warmth during the chilly winters, a popular choice amongst homeowners in recent years is the heat pump. This innovative system offers several benefits and can help lower your home’s energy consumption. But how exactly does a heat pump work in the winter? And would it be worth installing an outdoor unit in your home? These are questions we often receive here at The Comfort Group. As such, our team is going to outline some of the most critical aspects of how these units operate, so you can get a better idea about what to expect! So, if you want to learn more about heat pumps, keep reading!

How does air source heat pumps work when it’s cold outside?

In cold weather, a heat pump extracts heat from the outside air and transfers it within the house. The process begins when the air filter or outdoor unit’s refrigerant absorbs heat energy from the surrounding air and evaporates into a gas. The heat pump’s compressor compresses this gas, raising its temperature. The heated-up, compressed gas is pumped into the unit inside, where it condenses back into a liquid and warms the indoor air.

Furthermore, the air that has been heated is then distributed throughout the residence. The refrigerant then returns to the outside unit to complete the cooling mode of the cycle. While the efficiency of the heat pump decreases as the temperature drops, it remains capable of offering heating.

Does a heat pump run all the time in the winter?

In the winter, a heat pump does not operate continuously. A heat pump, like any other other heating and cooling system, functions based on the heating needs of your home. When the temperature within your home falls below the temperature set on your thermostat, the heat pump will turn on and begin to provide heat.

The heat pump will turn off once the temperature you want is reached. It will remain turned off until the temperature inside the house drops again, and extra warmth is required. The frequency with which the heat pump operates is determined by factors such as outside temperature, your ideal indoor temperature, your air conditioner and the quality of your home’s insulation.

Heat pumps, unlike furnaces, are designed to offer a constant, steady supply of heat instead of producing high bursts of heat. This gradual heating process keeps the indoor temperature comfortable and constant while optimizing energy efficiency. However, a heat pump’s efficiency decreases when temperatures outdoors get colder, so it may need to rely on supplemental heat from a backup system. By using a backup system, you can ensure that your home’s energy consumption remains as low as possible to save you money. At the same time, this two heating systems also provides you with the assurance that you’ll be able to heat your home sufficiently during extremely cold periods without having to worry about your heat pump.

What is the lowest temperature a heat pump will work?

Heat pumps are designed to work effectively even in much colder temperatures and environments, but their efficiency can suffer as the temperature drops. The lowest temperature where a heat pump can operate is determined by a variety of variables, such as the kind of unit, design, and how the unit has been installed.

In general, most modern heat pumps are capable of offering efficient heating at temperatures ranging from -3 to -1 degrees Celsius. However, as the temperature drops below freezing, the heat pump’s ability to draw heat from the air outside decreases, and it might need additional heat from a different source, like a boiler or furnace.

It’s also important to keep in mind that advancements have led to the creation of heat pumps made especially for colder climates. These models, also known as “cold-climate” heat pumps, are designed to operate effectively in temperatures that are as low as -26 degrees Celsius.

If you live in an area with in a harsh winter climate or frequently experience sub-freezing cold temperatures, you should consider a heat pump meant for cold climates or a dual-fuel system with a furnace as a backup heat source. A professional HVAC technician can give you the best advice based on the location you are in and weather conditions.

Can I use a heat pump with a furnace?

Absolutely! A front heat pump system can absolutely be used in conjunction with a furnace. A dual-fuel or hybrid heating system is designed to provide efficient heating in an array of weather conditions.

For milder temperatures, the heat pump takes the lead as the primary heating source in a dual-fuel system. It accomplishes this by absorbing heat from the exterior air and moving it into your home. When the temperature of cool air drops substantially, the heat pump’s efficiency falls, and the furnace kicks in to supply additional heat. The furnace is generally powered by natural gas or propane, keeping your home warm even during extreme cold spells.

This system is cleverly designed with a control system that shifts between the heat pump and the furnace according to outdoor air temperature as well as energy efficiency calculations. The goal is to use the most energy-efficient heating method for the current weather, maximizing both your consumption of energy and affordability.

By integrating a heat pump and a furnace in a dual-fuel system, you can benefit from the heat pump gas furnace’s energy efficiency and cost savings while still having a dependable heating source for those cold winter days. It’s important to note that the particulars of heat pump and furnace compatibility may vary, so consult with an HVAC professional to figure out the best setup for your home.
