One type of heat pump gaining popularity in Canada is the air-to-water heat pump. These heat pumps extract heat from the outside air, so they are influenced by the temperature outside. The “cut-out” temperature is the degree at which the pump shuts off. This concerns people. However, most of Canada is only rarely colder than the cut-out temperature. As new building and energy codes and new taxes emerge, air-to-water heat pumps are becoming more viable. Auxiliary heat sources can be used alongside the pumps. The question for the future isn’t “what is the cut-out temperature?” but “How can we make best use of the heat pump while it can operate?”
Key Takeaways:
- When the design temperature is below the heat pump cut out temperature, an auxiliary heat source is needed.
- The Federal carbon tax will push the industry towards electric heating solutions and air-to-water heat pumps.
- Instead of asking about cut-out temperature, ask about the best way to use the heat pump when it can operate.
“Air-to-water heat pumps extract heat from the air outside a building, so the machine’s ability to perform efficiently and provide useful heating is greatly influenced by outside air temperature.”
