CO2 Heat Pump Domestic Hot Water

The CO2 heat pump domestic hot water system is an energy-saving, environmentally friendly and efficient solution for home heating, cooling and domestic hot water (DHW).


Carbon dioxide is a natural refrigerant. R744 is non-toxic and non-flammable, the ozone depletion potential (ODP) is zero, and the global warming potential (GWP) is as low as 1. Safe, non-toxic, and highly efficient make it the best refrigerant.


The average COP of a CO2 heat pump system is 5, which means that for 1 kW of electricity input, it will produce approximately 5 kW of heat output. Compared with the traditional electric element hot water system, this reduces the use cost by about 80%.


The heat pump hot water system produces a stream temperature of 90 °C when the outdoor temperature is as low as -25 °C and the hot water COP is as high as 3.88.


As an environmentally advanced product, the CO2 heat pump system is an economical and environmentally friendly system. It is eligible for government awards which will save you a lot of costs.


CO2 Heat Pump Domestic Hot Water Features:
1). The reliability and outstanding performance of the world-renowned scroll compressor
2). Natural CO2 (R744, carbon dioxide) refrigerant. Its ODP is 0, GWP is 1, and it is non-polluting, non-toxic and non-flammable to the environment
3). Intelligent control: microprocessor digital controller with liquid crystal display
4). Adjustable water temperature: 25℃-90℃. There is no potential risk of contaminating drinking water
5). Can produce high temperature hot water at -20℃ outdoors
6). Blue hydrophilic aluminum fins, anti-corrosion, durable, low maintenance
7). Internally threaded copper tube, higher efficiency
8). The four-way valve ensures reliable defrosting function
9). Alco or Danfoss thermal expansion valve can more accurately control the pressure and temperature to ensure anti-fatigue and extend the service life.
10) Can be used for floor heating, fan coils, water heaters and modern radiators

Warranty:
1). Passed CE and RoHS certification
2). Service life is about 20 years
3). 2 years warranty, buy with confidence
