Understanding the Differences Between Heat Pumps and Furnaces
Heating accounts for a significant part of a home's energy cost.
Heating accounts for a significant part of a home's energy cost. Therefore, choosing an appropriate heating system is essential to maximize energy savings. Whether installing a heating system for a new home or looking to upgrade the existing unit, the two most popular choices for homeowners include a furnace or a heat pump. While the primary function of both heat pumps and furnaces is to keep the indoor air arm, they differ significantly.
The choice of heating system will impact the home's safety, comfort, warmth, and energy efficiency during winter. This post will highlight the significant differences between heat pumps and furnaces to facilitate decision-making.
Heat pumps
A heat pump is a heating and cooling device that does not generate heat but extracts it from the outside air and blows it indoors to maintain the desired home temperature. Heat pumps can reverse their function during summer and can be used to cool the home.
Furnaces
Furnaces use fuel like natural gas, oil, or propane to generate heat. Furnaces powered by electricity are also available.
Heat pumps vs. furnaces
Cost
Cost plays a vital part in selecting the heating system for a home. Households with easy access to fuels like oil, propane, and natural gas will find a furnace more cost-effective. But if electricity is more affordable and fuel is not readily accessible, a heat pump will make a better choice. Homeowners can also opt for dual fuel systems to control their energy costs better.
Maintenance
While heat pumps and furnaces require regular preventative maintenance to last longer and work more efficiently, the upkeep requirements for heat pumps are more than for furnaces. While frequent filter changes and vacuuming are enough to keep the furnace functioning smoothly and efficiently, a heat pump requires removing debris around it for proper airflow, keeping it clear of ice and snow, and cleaning dirty coils besides the filter change.
Energy efficiency
Heat pumps are highly efficient and have a lower operating cost than a furnace. Heat pumps require less energy for their operation. However, in colder climates, with frigid temperatures, heat pumps have to work much harder to transfer heat, making them less efficient. As furnaces generate heat using fuel, they are a better option for colder climates and work more efficiently.
Noise
A heat pump is noisier than a furnace. The heat pump's compressor makes significant noise. However, the furnace usually remains out of sight, installed in the basement or utility room, and is much quieter and unobtrusive.
Average lifespan
A furnace is not as complicated as a heat pump and has an expected lifespan of up to 20 years with proper maintenance. A heat pump can last for about 15 years with regular maintenance.
Which is better? A heat pump or furnace
Both heat pumps and furnaces have their pros and cons. While a stove requires less maintenance and lasts longer but has a high operating cost, a heat pump has low operating and installation costs but is noisier and unsuitable for colder climates.
Which one will work the best depends on the local climate and specific household requirements. A local HVAC expert will understand the family's needs and evaluate the different factors to suggest the best heating system for the home.
