–Heat Pump vs Furnace: know all about the heating systems
When it comes to heating your home, you have a few options to choose from. Depending on where you live will of course influence the options available to you. Two of the most popular heating systems are heat pumps and furnaces. But how do you know which one is the best choice for you? In this article, we'll explore the differences between heat pumps and furnaces, the benefits of heat pumps, and whether you can use a heat pump as a furnace replacement.
Furnace Vs. Heat Pump: Differences
Heat pumps and furnaces both provide warmth to your home, but they work in different ways.
A furnace uses fuel, such as natural gas, propane, or oil, to generate heat. The heat is then distributed through your home using a system of air ducts and vents.
A heat pump, on the other hand, uses electricity to extract heat from indoor spaces by cooling them during the summer months and, in winter, to transfer heat indoors by reversing the cycle (yes, even in winter it is possible to extract heat from outdoor air thanks to the properties of the refrigerant fluid!).
There are two types of heat pumps:
- Air-to-air heat pumps use indoor units such as wall-mounted, consoles or ducts to transfer cold or heat indoors through the air.
- Air-to-water heat pumps transfer external heat to water via radiators or underfloor heating, and can even provide cooling and domestic hot water.
Why are Heat Pumps more efficient than Furnaces?
Heat pumps are more efficient than other heating systems as they do not use additional fuel to generate heat but only electricity to keep it running. Compared to a traditional heating system, heat pumps are up to 3x more efficient, using less energy to produce the same amount of heat (for every kilowatt of electricity the heat pump uses you will get 3 to 4 times more heat).
Additionally, heat pumps can operate in both heating and cooling mode, allowing you to use the same system for both heating and cooling your home while reducing installation and maintenance costs.
Can a Heat Pump replace a Furnace?
Air-to-air heat pumps remain an efficient source of heat in conditions as low as -20°C, a temperature rarely reached in most climates. However, if you live in a climate that regularly drops below that temperature, you will probably need a back-up heating system for very cold days. But even in this situation, it would be worth considering the installation of a heat pump in winter conditioners to reduce your annual fuel consumption.
In the case of air-to-water heat pumps, they can withstand lower outdoor temperatures down to -25°C, relying on an electrical resistance in extreme weather conditions.
Maintenance of a Furnace Vs. maintenance of a Heat Pump
Both heat pumps and furnaces require regular maintenance to ensure they are operating efficiently.
Furnaces typically need to be serviced once a year, and the filter should be changed every month or two.
Heat pumps also need annual servicing, and the outdoor unit should be cleaned regularly to remove any debris that may have accumulated.
What is the average life of a Furnace?
The average life expectancy of a furnace is 15-20 years. However, this can vary depending on the type of furnace you have and how well it is maintained.
How many years does a Heat Pump last?
Heat pumps can last up to 15 years with proper maintenance. Like furnaces, the life expectancy of a heat pump can vary depending on the type of heat pump you have and how well it is maintained.
Will a Heat Pump add value to my home?
Heat pumps can potentially add value to your home since they are more energy-efficient than furnaces, which can lead to lower energy bills and potentially higher resale value. According to the U.S. Department of Energy, heat pumps can save homeowners up to 50% on their heating and cooling costs compared to furnaces. Additionally, air source heat pumps are far more environmentally friendly than traditional furnaces.
Benefits of Heat Pumps over Furnaces
There are several heat pump benefits compared to furnaces:
- Energy efficiency: As mentioned above, for every kilowatt of electricity the heat pump uses you will get 3 to 4 times more heat due to the fact that they do not burn fuel, which can result in significant savings on your energy bills.
- Environmentally-friendly: Heat pumps use electricity to move heat rather than burning fossil fuels, making them a more environmentally-friendly option.
- Space and installation: Air-to-air heat pumps are typically smaller and easier to install than furnaces, which makes them a good option for homes with limited space or difficult-to-access areas.
- Versatility: Heat pumps can be used for both heating and cooling, as well as for domestic hot water in case of air-to-water systems, making them a more versatile option than furnaces.
