aroSTOR hot water heat pump
Most sustainable water heating with environmental heat
- Perfect for new construction and modernisation – hot water for up to six persons
- Protect the climate – with new, eco-friendly refrigerant technology
- Save energy – without operating noise
- Become more independent of the energy market - by combining with solar or photovoltaics
- Take advantage of the additional cooling function
Eco-friendly water heating for all needs
Whether you are modernising a single-family house or building a new one, with our new aroSTOR hot water heat pump, you can use the air as a renewable heat source for an eco-friendly and efficient hot water supply. The aroSTOR comes as either a floor-standing or a wall-mounted unit. The floor-standing models are available with output ratings of 200 and 270 litres, to meet the hot-water requirements of up to six persons without difficulty. For low to moderate needs, we offer you our wall-mounted devices with output ratings of 100 and 150 litres.
Made for the climate requirements of tomorrow
Thanks to the new natural refrigerant R290, your choice of the aroSTOR is a safe investment, as it is built to fulfil the more stringent future standards of the European F-gas Regulation for climate protection. Enjoy the best comfort with a clear conscience at all times.
Proven efficient, convincingly quiet
With the aroSTOR hot water heat pump, you transform 1 kWh of electric energy into over 3 kWh of thermal energy for water heating. A look at the efficiency label confirms this: with its A+ energy efficiency class, the aroSTOR stands up to any comparison. Likewise for operating noise: with a maximum sound pressure level of 41 db(A) at a distance of one metre, the aroSTOR is quieter than a modern refrigerator – and can therefore be installed in your living space without any problem.
Even better with solar electricity
The aroSTOR can be combined especially easily with a photovoltaic system. This gives you the advantage of being able to use self-generated electricity year-round. As soon as the sun delivers enough energy, the photovoltaic system’s energy manager switches the aroSTOR on. The result: with the aroSTOR, you reduce not only your CO2 footprint, but also your energy costs.
Use the aroSTOR for cooling as well
If the aroSTOR is located in a room, you can conduct the cool exhaust air via an air exhaust duct into another room – the pantry, for example, to keep food fresh longer.
