Boiler structure
Save energy X
Saves up to 75% electricity
compared to conventional
boilers thanks to high COP value
Extremely quiet operation X
At only 50 dB(A), the AquaWIN Atmo is barely audible and
extremely quiet.
Hygiene and quality X
Enamelled boiler with magnesium protective anode
Space-saving & versatile X
The compact design already contains all the important components
such as heating element, solar register and Modbus interface for
easy integration into the energy management system.
A true all-rounder X
In doing so, you make optimal use of renewable energy sources such as photovoltaics, solar thermal energy or biomass.
This reduces operating costs, protects the main heating system and increases your independence.
Future-proof & efficient X
The environmentally friendly refrigerant R290 has an extremely low
global warming potential (GWP = 3) and ensures high efficiency.
More than just hot water X
It can also be used for cooling and dehumidifying the basement.
Convincing down to the last detail
- The heat pump unit uses warm indoor or outdoor air to heat the water in the tank particularly efficiently. Compared to a purely electric boiler, electricity consumption can be reduced by up to 75 percent.
- The AquaWIN Atmo can be combined with a photovoltaic system. When solar energy is available, the drinking water is heated virtually free of charge using the heat pump.
- The enamelling and the standard magnesium protective anode ensure that the tank is protected against corrosion and remain hygienic.
- The condenser transports the heated refrigerant, which transfers the heat to the water inside. The AquaWIN Atmo has a safety condenser that is located on the outside of the tank. This prevents the refrigerant from entering the drinking water in the event of a leak.

Types of water heating
The AquaWIN Atmo can heat drinking water in three different ways. Depending on your preferences or the season, hot water can be produced using either the heat pump unit alone, the heat pump in combination with electricity from the PV system, or the existing boiler.
Heat pump
In summer and during the transition period, hot water preparation with a heat pump is particularly efficient and economical. The boiler is spared 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 for hot water preparation with the heat pump. As soon as voltage is applied to the inverter, it sends a signal to the AquaWIN Atmo and the water is automatically heated to 62 °C.
Boiler
In winter, when the boiler is in operation for space heating anyway, it can of course also be used for hot water production at the same time.
