The aroSTOR plus is an eco-friendly hot water heat pump designed for indoor installation. With 200 and 260-litre cylinder options, it fits perfectly into your modernisation or new build project, providing maximum hot water comfort for households of up to six people*. Its advanced technology transforms air into renewable heat, efficiently converting one kWh of electric energy into up to 3.43** kWh of thermal energy, helping you save on your energy bill. Pair it with a PV system for even greater savings, and enjoy hassle-free, space-efficient installation.

Experience the comfort, enjoy the savings.

The aroSTOR plus enhances efficiency with up to 11% better COP than its predecessor. Its advanced heat pump technology produces over 3.43** times more heat than the electrical energy it consumes. This means that, when you replace a conventional electric water heater with aroSTOR plus, you can reduce your energy costs by the same factor - and even gain more energy savings when an PV system is used as well.
Can handle your whole family.
The aroSTOR plus offers 200 or 260 litres storages of domestic hot water, ideal for bigger families of three to six*.

It's your free choice to either minimise your electrical consumption or enjoy highest DHW comfort with an always constant water supply and no time delay - supported by the back-up heater or even an additional boiler.

The heat pump can even achieve water temperatures of up to 65°C degree for a greater hot water amount.
Seamlessly fits your modernisation or new build.
The aroSTOR plus is easy to install, whether you're updating a conventional electric storage tank or fitting it into a new build. With the new side air duct connections, it fits perfectly even in smaller spaces or lower-ceiling locations. The appliance draws energy from ambient or external air, even in temperatures as low as minus seven degrees Celsius. With its fully indoor installation, there's no need for an external setup. Plus, when using internal air, the cool exhaust can keep spaces like pantries refreshingly cool and dehumidified.

Control made clear and easy.

The new semi-touch LED display, featuring clear icons, makes it simple to select the mode that suits your individual preference —whether it's enjoying maximum comfort or maximising energy savings.

A true team player when it comes to energy savings.

The aroSTOR plus easily integrates into your existing PV system, enabling electricity from a PV installation or also from an energy provider to be used in an economically optimized way. This adds up to the savings already provided by heat pump technology. Enjoy more savings and greater autonomy.

Climate-friendly performance inside.

The aroSTOR plus uses R290 refrigerant, which has the lowest GWP (Global Warming Potential) of only 0,02. Moreover, the appliance only uses this refrigerant in a very small quantity of 150 grams. This means, that even in the unlikely event of an accidental leak, the impact on the greenhouse effect is minimal.
