R290 energy label A+++

key function

Key Functions:

R290 Green Gas at low GWP(3)

  • R290 is one of the best refrigerant available for mass production upto now: Negligible Global Warming Potential(GWP) and degradation time is considered in monthes

  • Zero ozone layer depletion potential(ODP)

  • Permanent green

  • Less load for the same performance

  • Low energy consumption and higher efficiency

Refrigerant Revolution

DHW tank disinfection

By heating the water in the system to 65°C, the high temperature kills most bacteria (including Legionella).

DHW tank disinfection

Climate cruve

Eco mode is an intelligent energy-saving mode that can minimize energy consumption while ensuring comfortable temperatures, achieving green environmental protection for air source heat pumps.


Floor preheating and drying

Protect your home floor by activating the Floor Preheating function which slowly increases the heating temperature of the floor coils, avoiding possible floor damaging and transitioning smoothly to the heating function. The Floor Drying Up function provides an additional solution to the installer as it helps remove any residual moisture from newly installed floor coils, further protecting the installation and ensuring the optimal and effective operation of the heat pump.


Two heating circuits

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


Application with multiple heat source

Application with multiple heat source

Smart design to work with other heating facilities in your house, like solar, gas boiler and etc, make sure you to pay the lowest bill for heating !

Application with multiple heat source

The working principle of heat pump water heaters:

A heat pump works in the same way as a reverse-cycle air conditioner. Instead of heating the room, it heats the water.

Here are a few simple steps on how a heat pump works:

  • The heat pump system works by moving heat from the air in the room to the water in the tank.

  • The fan draws air onto fins called evaporators.

  • The heat in the air is absorbed by a refrigerant that flows through an evaporator.

  • The refrigerant is then compressed into a vapour, which raises the temperature and pressure.

  • The hot vapor then flows through a heat exchanger, which heats the water and cools the refrigerant.

  • Once the vapour refrigerant has given all its heat, it is then transformed into its liquid state and cycled up to start again at the evaporator.

Wotech heat pump water heater is reversible,can heat or cool buildings and, in some cases, supply domestic hot water as well.

However, you may need bigger radiators or underfloor heating to make the most of this system as the output is cooler than from a traditional boiler or furnace.
