AquaWIN Air3

The intelligent DHW heat pump

With the heat pump integrated in the AquaWIN Air3, you can heat your water during the summer months without having to switch on your boiler. The AquaWIN Air3 therefore allows you to reduce your electricity costs by up to 75 per cent compared against conventional electric hot water tanks. The Windhager DHW heat pump is a true virtuoso – it doesn't matter whether you are using your own photovoltaic power, connecting your thermal solar heating system or incorporating your boiler. The AquaWIN Air3 provides you with a number of ways to heat your water.

Cogent to the smallest detail
 

  • Using the warm room or outdoor air, the heat pump unit can heat the water in the tank particularly efficiently. Compared to a purely electric hot water tank, electricity consumption can be reduced by up to 75 per cent.
     
  • The air inlets and outlets of the AquaWIN Air3 can be rotated 360°C. This is particularly advantageous if the room height is low or if the domestic hot water heat pump is installed in a corner.
     
  • The AquaWIN Air3 can be combined with a photovoltaic system. If solar energy is available, the drinking water is heated virtually free of charge with the heat pump.
     
  • The enamelling and the standard protective magnesium anode ensure that the tank is protected from corrosion and also ensure hygiene.
     
  • The radio remote control can be used on the unit or "mobile" as a remote control – so settings can also be made on the AquaWIN Air3 and information read from other rooms.
     
  • The condenser transports the heated refrigerant, which transfers the heat to the water inside. The AquaWIN Air3 has a safety condenser that is located on the outside of the tank. This prevents the refrigerant entering the drinking water in the event of a leak.

Types of hot water provision
 

The AquaWIN Air3 can heat the drinking water in three different ways. Depending on the requirements or the time of year, hot water can be provided either by only the heat pump unit, or by the heat pump together with electricity from the PV system, or also by the existing boiler.

Heat pump
In summer and during transitional periods, hot water provision with the heat pump is particularly efficient and economical. The boiler is protected and no additional fuel is required.

Photovoltaic system
If you have your own photovoltaic system, the virtually free electricity from the sun can of course also be used to heat water with the heat pump. As soon as there is voltage at the inverter, it sends a signal to the AquaWIN Air3 and the water is automatically heated to 62°C.

Boiler
In winter when the boiler is already operating for space heating, it can also be used to provide hot water at the same time.
