R290 heat pump water heater


Features:

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

Environmental Refrigerant

R290 Green Gas at low GWP(3)

R290 is one of the best refrigerants available for mass production upto now: Negligible Global Warming Potential (GWP) and degradation time is considered in months: Zero ozone layer depletion potential (ODP): Permanent green: Less load for the same performance;  Low energy consumption and higher efficiency.

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. With good performance in this range of water temperatures, it is now possible to replace an old gas/oil boiler with an air-to-water heat pump unit without changing the existing heating distribution system or even the old radiators inside.

Refrigerant Revolution

ENERGY EFFICIENCY RATING LABEL

Wotech R290 Air to Water Heat Pump is specially developed with the most cutting-edge heat pump technology and modern design to meet stringent requirements for efficiency, stability and quietness. Not only does it use R290 green gas and inverter technology, but it is also rated with the A++ energy label. With a top energy rating of A+++, the unit is energy efficient and can significantly reduce the user's energy bill.

R290 energy label A+++

Smart control system

* Smart logic to run between hot water and domestic heating, satisfying different heat demands.

* 8 different languages available, user-friendly for many countries.

* Combination of multi-heat source, E-heater, solar panel or boiler etc, heat your house intelligently. 

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

Air to water heat pump

Wotech air to water Heat Pump for residential and commercial applications.  Offering capacities from 5kW all the way up to 30kW, this ensures a system that will work regardless of your heating and cooling needs. Suitable for new build and refurbishment projects, the solutions are cost-effective with minimised environmental impact.

Higher Efficient:Heating/Cooling

Climate curve

Users can set up the system according to their ideal comfort levels based on the changing levels of heat demand, insulation, etc., with proprietary Heating Curve Logic. By continually monitoring and adjusting the outlet water temperature in opposite directions with the current ambient temperature levels, the Wotech air to water heat pump will ensure optimal comfort in the living spaces by adjusting the outlet water temperature based on the ambient temperature.Climate curve


DHW tank disinfection

Maintain pristine quality of the water tank's DHW and eliminate germs and bacteria by increasing the temperature of the water in it up to 65C.DHW tank disinfection
