R290 heat pump water heater

Features:

Using energy-efficient inverter compressors, Wotech heat pumps have variable heating capacities that can be adjusted.In this way, the whole system will be more efficient and the pump's operation costs will be reduced.Heat is generated more efficiently with a higher coefficient than with a lower coefficient.

multiple heat recovery technology

R290 Green Gas at low GWP(3)

Thanks to the use of R290, Wotech R290 air to water heat pump is now not only the best solution for new buildings, but also possible to fit the retrofit market by lifting up maximum heating temperature to 70°C. Using energy-efficient inverter compressors, Wotech heat pumps have variable heating capacities that can be adjusted.In this way, the whole system will be more efficient and the pump's operation costs will be reduced.Heat is generated more efficiently with a higher coefficient than with a lower coefficient.

ENERGY EFFICIENCY RATING LABEL

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 energy label A+++


Full Inerter Technology

DC inverter technology enables the heat pump to adjust its frequencyaccording to real heating requirement. With this technology, Wotech R32/R290 air to water heat pump achieves an energy level of A+++ according to Erp directive.

Application with multiple heat source


Two heating circuits [as standard]

• More flexibility thanks to two control zones

• Independent control of underfloor heating and radiator heating temperature

• No need to purchase an extension module for second heating system

Two heating circuits

DHW tank disinfection

The water inside the HWT (hot water tank) must be periodically heated to temperatures over 65°C to eliminate bacterial growth inside the tank if domestic hot water is provided directly from the tank.For healthy living, Wotech air source heat pump automatically controls this function based on parameter settings.

Climate curve

You can choose different climate correlation curves or your own customised curve. Once the curve is selected, the unit sets the outlet water temperature automatically according to the outdoor ambient air temperature.

Climate curve


Air source heat pump

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  Wotech air to water heat pump can adjust the outlet water temperatures based on the ambient temperature,by continually monitoring and adjusting it in opposite direction with the current ambient temperature levels to ensure the optimum comfort in the living spaces
