High Temperature Hot Water Heat Pump

The high temperature hot water heat pump running with carbon dioxide (R744) can provide hot water up to 90°C for home or commercial heating systems.

The global warming potential (GWP) of R744 or CO2 is 1, which is the lowest possible value, but the device can still provide full heating capacity as low as -3°C outdoor temperature, and at temperatures as low as -25°C Run efficiently and effectively.

Compared with a typical gas boiler, this equates to a total carbon saving of up to 78%. Compared with direct electric heating systems, these high efficiency heat pump also significantly save operating costs and carbon emissions.

The high temperature heat pump is designed for sanitary hot water applications such as homes, villas, hotels, leisure centers, hospitals, nursing homes, restaurants, schools and universities.

High Temperature Hot Water Heat Pump 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

Heat Pump Components:

1. Silver welding

Silver welding technology makes the unit system more reliable; it is likely to avoid refrigerant leakage

2. Intelligent control

The unit adopts an intelligent control system: microprocessor digital controller, liquid crystal display

3. Shell and tube

Heat Exchanger High-efficiency shell-and-tube water heat exchanger, the highest working water pressure can reach 3.2Mpa

3. Reliability of Alco thermal expansion valve

4. Efficient and environmentally friendly refrigerant, does not destroy the ozone layer

5. Low noise fan

Axial fan is adopted, with large air volume and low operating noise

6. Air pressure drive water flow control valve

The water flow is controlled by the pressure of the refrigerant to ensure that the hot water supply can be adjusted at a constant temperature
