Tongyi heat pumps use heat pump refrigerant R290 and R32 to reduce their environmental impact and lower their Global Warming Potential (GWP).

Tongyi’s new heat pump refrigerant R290 is more environmentally friendly than R32, with a smaller impact on climate change and no contribution to ozone depletion. This refrigerant also complies with new regulations in certain regions, such as the upcoming phase-out of R32 in Europe.

However, it’s important to note that heat pump refrigerant R290 is flammable, while R32 is not. This makes R32 heat pumps safer for use in homes and businesses.

In summary, heat pump refrigerant R290 is the better choice for the environment, while R32 remains the safer option for installation and use.

The best refrigerant for you depends on your individual needs and preferences. If environmental impact is your priority, heat pump refrigerant R290 is the better choice.

Both R32 and heat pump refrigerant R290 are considered low-impact options, significantly better for the environment compared to traditional refrigerants like R410A.

Tongyi heat pumps offer models that use both R32 and heat pump refrigerant R290, giving you the flexibility to choose the refrigerant that suits your specific needs.
