Cold climate air source heat pumps are becoming increasingly popular in areas with harsh winters like Ottawa. They offer a more energy-efficient and cost-effective alternative to traditional heating and cooling systems. In this pamphlet, we’ll explain the basics of how cold climate heat pumps work, their benefits and drawbacks, and what to consider before installing one in your home.
How Do Cold Climate Heat Pumps Work?
Cold climate heat pumps work by extracting heat from the air outside and transferring it inside your home using refrigerant. This process is reversed during the summer months to cool your home. Unlike traditional furnaces, heat pumps don’t generate heat; they simply move it from one place to another. This makes them more efficient since they use less energy to move heat than to generate it.
Benefits of Cold Climate Heat Pumps:
Energy Efficiency: Cold climate heat pumps can be up to three times more efficient than traditional heating systems, which can save you up to 50% on your energy bills.
Environmentally Friendly: Since cold climate heat pumps use less energy, they also produce fewer greenhouse gas emissions, which can help reduce your carbon footprint.
Quiet Operation: Cold climate heat pumps are much quieter than traditional heating systems, making them ideal for urban areas or small spaces.
Year-Round Use: Cold climate heat pumps can also be used for cooling during the summer months, providing a complete heating and cooling solution for your home.
Drawbacks of Cold Climate Heat Pumps:
Initial Cost: Cold climate heat pumps can be more expensive to install than traditional heating systems, although this cost can be offset by the long-term energy savings.
Efficiency Decreases in Extreme Cold: In extreme cold temperatures, cold climate heat pumps may not be able to extract enough heat from the air outside to adequately warm your home. In these cases, a supplemental heating system may be needed.
Considerations Before Installing a Cold Climate Heat Pump:
Climate: Cold climate heat pumps are best suited for areas with moderate to mild winters. In areas with extreme cold temperatures, a supplemental heating system may be needed.
Home Size: Cold climate heat pumps are most efficient in smaller homes. For larger homes, multiple units may be needed.
Existing Ductwork: If you have existing ductwork, a cold climate heat pump can be easily integrated into your current system. If not, additional installation costs may be incurred.
Cold climate air source heat pumps offer many benefits for homeowners, including energy efficiency, environmental friendliness, and year-round use. However, they may not be suitable for all homes and climates. If you’re considering installing a cold climate heat pump in your home, consult with one of our heat pump specialists to determine if it’s the right choice for your specific needs.
