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).

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


There are 2 types of auxiliary heating:

  1. Electric resistance heating, which uses heat strips (standard with every heat pump) installed in your ductwork. This type of heating is highly inefficient.


  2. Gas furnace or other heating source, called a “hybrid system heat pump”.  You add a heat pump to your existing home heating system, and you also install integrated controls. The integrated controls automatically switch between the heat pump and your current heating system based on your chosen temperature.


    For instance, if you have a heat pump that works very efficiently in temps down to -10 degrees Fahrenheit, you may want to set up the system so that it uses the heat pump by default, and then when the temps drop lower than -10, the system automatically switches to using your other heating method.


    A hybrid heating system can save you between 30 and 50% on your heating bills.Wotech heat pumps can work together with multi-heat source, E-heater, solar panel or boileretc, heat your house intelligently.


When is Auxiliary Heat Needed?

  • When the temperature outside is below freezing

  • You need a high increase in temperature

  • The heat pump is in defrost mode

  • Emergency Heat Setting Is Turned On


Indications That Your Auxiliary Heat Is Malfunctioning

  • The auxiliary heat remains active even after adjusting your thermostat.

  • The defrost mode remains activated for a prolonged period, exceeding the usual duration.

  • Your electricity bill shows an unusual increase.

  • Your heat pump continues to operate in auxiliary mode for an extended period.


While air-source heat pumps are an energy-efficient heating and cooling solution in mild climates, they often require auxiliary heat sources in colder regions. 


The limitations of air-source heat pumps at low temperatures make it necessary to supplement them with additional heating systems. Electric resistance heaters, gas furnaces, and hydronic heating systems are commonly used as auxiliary heat sources. By combining these systems, homeowners can ensure comfortable indoor temperatures even in the coldest weather conditions.
