In 2025, air-to-water heat pumps (AWHPs) are transforming the way people heat and cool their homes, playing a pivotal role in global sustainability efforts. As part of Canada’s strategy to achieve net-zero emissions by 2050, AWHP adoption has started to surge, driven by their exceptional energy efficiency, ability to reduce carbon emissions, and compatibility with renewable energy sources.
Efficiency and Emission Reduction
AWHPs extract ambient heat from the air - even in sub-zero temperatures - and transfer it into water for heating and cooling. With a coefficient of performance (COP) of 3 to 4, they offer 3 to 4 times more energy output than the electricity they consume. This efficiency dramatically reduces reliance on fossil fuel-based systems, helping Canada’s building sector—which accounts for nearly 13% of the country’s emissions—move toward decarbonization.
Refrigerant Changeover: Enhancing Sustainability
In tandem with AWHP adoption, the industry is undergoing a refrigerant changeover to reduce global warming potential (GWP). Older refrigerants like R-410A are being phased out in favor of environmentally friendly options such as R-452B and A2L-class refrigerants. These next-generation refrigerants have significantly lower GWP, improving the sustainability of AWHP systems while meeting updated safety and performance standards. The shift not only supports international climate agreements like the Kigali Amendment but also aligns with Canada’s ambitious climate goals.
Integration with Renewable Energy
Canada’s renewable energy infrastructure amplifies the benefits of AWHPs. Provinces like British Columbia, Manitoba, and Quebec, which rely heavily on hydroelectricity, achieve near-zero carbon heating and cooling with AWHPs. These systems can also pair seamlessly with solar or geothermal energy for off-grid applications, offering a pathway to fully renewable living.
Economic and Practical Benefits
AWHPs also provide significant cost savings, reducing energy bills by up to 50% compared to traditional systems. Their dual functionality for heating and cooling ensures year-round utility, while their reliability in extreme temperatures makes them ideal for Canada’s diverse climate, including remote and off-grid communities.
Vancouver’s Leadership in Sustainability
Vancouver, British Columbia, is at the forefront of Canada’s sustainability efforts, bolstering the heat pump market through progressive policies. The city has maintained a ban on natural gas connections in new buildings, effectively phasing out fossil fuel heating systems. This initiative directly reduces carbon and air pollution while encouraging the adoption of clean heating technologies such as AWHPs. These policies maximize the environmental benefits of heat pump systems and set an example for other urban centers aiming to achieve net-zero emissions.
Driving Global Sustainability
By adopting AWHPs and advancing refrigerant technologies, Canada is positioning itself as a leader in global climate action. These systems align with the United Nations’ Sustainable Development Goals (SDGs), particularly affordable clean energy and climate action, while helping to set a benchmark for other nations.
As 2025 progresses, air-to-water heat pumps are more than just a technological upgrade-they are a cornerstone of Canada’s commitment to a sustainable, low-carbon future. With continued innovation and investment, their role in combating climate change will only grow stronger.
