As the world moves towards more sustainable energy solutions, the heat pump industry is seeing an exciting revolution, led by the adoption of R290 refrigerant. At Tongyi Heat Pumps, we are committed to advancing eco-friendly technologies, and our latest range of air-water heat pumps harnesses the benefits of R290 to deliver both high performance and low environmental impact.
What is R290 Refrigerant?
R290, commonly known as propane, is a natural refrigerant with an exceptionally low climate impact. Under the current EU F-gas framework, R290 has a GWP100 of 0.02 and an Ozone Depletion Potential (ODP) of 0. Older technical references may show a GWP value of 3 because they use earlier assessment methodologies.
Low Energy Consumption, High Efficiency
One of the standout advantages of using R290 in Tongyi Heat Pumps is its high efficiency. Combined with our twin rotary DC inverter compressor, our heat pumps consume up to 30% less power than conventional systems. This cutting-edge compressor technology operates across a wider frequency range, allowing for precise temperature control and optimizing energy usage under different loads.

Wide Ambient and Water Temperature Range
Tongyi’s R290 heat pumps are designed to operate across a wide range of outdoor temperatures. With operation down to -25°C and hot water production up to 75°C, the current R290 air-to-water range provides heating, cooling and domestic hot water for year-round use.
