R290 A+++ Residentail Air Source Heat Pump with Wifi Function

Availability:


R290 heat pump water heater


Features:

Wotech Air Source Heat Pump incorporates a high-efficiency compressor, a completely new high-efficiency heat exchange system, high-precision electronic expansion valves and other accessories. COP has met national level energy efficiency standards and received national energy efficiency certification.


R290 Green Gas at low GWP(3)

To reduce carbon emissions to the environment and curb global warming, Wotech developed the R290 air-to-water heat pump.  With many advantages such as low carbon emissions and high efficiency, the R290 refrigerant is recognized as the refrigerant with the most potential for development in the industry, contributing to the reduction of carbon emissions and helping to achieve the global goal of carbon neutrality.Refrigerant Revolution

ENERGY EFFICIENCY RATING LABEL

Wotech heat pumps are equipped with energy-efficient inverter compressors that allow variable heating capacity adjustment. This increases the efficiency of the entire system and reduces the operating costs of the pump.  The higher the coefficient, the more heat can be generated using the same amount of electricity.

R290 energy label A+++


Full Inerter Technology

DC inverter conversion techniques can achieve equilibrium temperatures, saving power and energy.  It adopts DC frequency conversion continuously variable adjustment, which has the advantages of strong power, high efficiency, low noise, stable and reliable performance, and long service life.

Application with multiple heat source


Air souce heat pump

Air source heat pumps extract thermal energy (heat) from the outside air and convert this into heating and hotwater for your home. Air source heat pumps are designed to work in cold temperatures and are suitable for arange of homes, from a small apartment to a large detached home. Air source heat pumps do require electricity to operate, but 75% of the energy required is generated from the outside air, with only 25% being required fromelectricity. This means that 75% of the energy you use will be from a renewable source, which will reduce youremissions and CO2 impact.

Climate curve

Using proprietary Heating Curve Logic, users can set up the system to meet their optimum comfort levels based on the changing heat demand, insulation levels, etc. A constant monitoring of the current ambient temperature can enable Wotech air source heat pump to adjust the outlet water temperature in the opposite direction to ensure the optimum level of comfort in the living spaces.图片14


Floor heating

With Floor Preheating, you can avoid potential floor damage and smoothly transition from the preheating to the heating function, avoiding any floor damage.In addition to protecting the installation, the Floor Drying Up function ensures the heat pump operates optimally and effectively by removing any residual moisture from newly installed floor coils.
