Eco-Conscious Heating: The Advantages of R32 Split Air To Water Heat

Utilizing eco-friendly R32 refrigerant, AXEN's R32 air to water heat pump offers efficient heating with reduced environmental impact. R32's smaller volume and easy recyclability contribute to lower carbon emissions, reducing global warming potential by up to 75% compared to R410A. This eco-conscious design ensures sustainable heating solutions for both residential and commercial applications.

How R32 Split Air to Water Heat Pumps Work?

R32 air to water heat pump works by transferring heat from outdoor air to water through refrigerant piping. The outdoor unit extracts heat from the ambient air and transfers it to the indoor unit via refrigerant piping. Inside, the heat of r32 air to water heat pump is used to heat water for space heating or domestic hot water. This process, similar to that of R290 heat pump water heater, efficiently provides heating and hot water while reducing environmental impact.




R32 Air to Water Heat Pump vs R290 Air to Water Heat Pump

When comparing R32 and R290 air-to-water heat pumps, the choice often comes down to environmental impact, energy efficiency, and system performance. R32 refrigerant offers high energy efficiency and is compatible with a variety of systems, but it has a moderate Global Warming Potential (GWP) of 675—significantly lower than older refrigerants like R410A. In contrast, R290 (propane) stands out as a natural refrigerant with an ultra-low GWP of 3, making it an exceptionally eco-friendly choice.


R32 air-to-water heat pumps are widely used due to their efficient performance and compatibility with existing technologies. However, R290 air to water heat pumps are gaining traction for their superior sustainability and ability to meet stringent environmental regulations. While R290 systems require advanced safety measures due to the refrigerant’s flammability, they offer exceptional energy efficiency and long-term cost benefits.


Ultimately, the choice between R32 and R290 depends on specific requirements. R290 is the ideal option for those prioritizing environmental sustainability and lower emissions, while R32 remains a solid choice for those seeking a balance between efficiency and ease of use.
