Three Features

Discover the three features you can choose from to tailor the range to meet your climate needs:


The Heating Only function is standard in the Daikin product range and is available for all three indoor units. This setting provides space heating and domestic hot water. ​


If you need comfort cooling in addition to heating and hot water, then the Reversible function is the best solution. Available for all three indoor units, this feature allows the system to reverse its operation to provide cooling instead of heating. This setting requires an underfloor piping system or fan coil units.


The integrated floor standing unit is the only indoor unit equipped with a Bizone setting. With Bizone, you can choose to manage and control the temperature of two seperate zones in your home that use different emitters, like radiators or underfloor heating.

How a heat pump works

A heat pump controls the temperature by transferring heat. There are three essential components to a heat pump: the outdoor unit (evaporator), the indoor unit(s) (condenser) and the refrigerant. The refrigerant transfers the heat as it circulates between the outdoor and indoor unit(s):


So what does it actually do?

  • The evaporator extracts energy from the renewable source (air, water, geothermal or solar) by forcing the liquid to transform into a gas.
  • The compressor compresses the gas, which raises its temperature.
  • The condenser exchanges the heat from the gas to the heating system, and the gas returns to a liquid state.
  • The expansion valve lowers the pressure of the refrigerant, which triggers evaporation and the cycle begins all over again.

We simply reverse this cycle to cool your home.
