Product description: Vaillant aroSTOR hot water heat pump – for indoor installation

Efficient heat pump technology

The Vaillant aroSTOR hot water heat pump uses state-of-the-art heat pump technology to efficiently convert thermal energy stored in the air into hot water. This system operates completely independently of an existing heating system, allowing for versatile application in various living situations.

Through the use of innovative technology, the aroSTOR not only ensures a high level of hot water comfort, but also economical and environmentally friendly energy conversion, which also leads to low operating costs.

Two storage options to suit individual needs

With available storage capacities of 200 and 270 liters, the heat pump offers various options that can be ideally adapted to the hot water requirements of single-family homes. This allows for optimal supply of both new builds and renovations.

This flexible storage selection allows the technology to be used in a targeted manner to adapt to different consumption profiles and structural conditions, while always guaranteeing maximum comfort.

Flexible integration into existing heating systems

The aroSTOR can be easily integrated into existing heating systems, for example in combination with gas or oil boilers. Thanks to its simple installation, it is ideally suited as an entry point into future-oriented heating technology, even in existing buildings.

This option allows the existing energy balance to be expanded to include an environmentally friendly and cost-effective component without requiring extensive renovation work.

Optimal use with photovoltaic systems

Owners of photovoltaic systems benefit particularly from the aroSTOR heat pump. Thanks to its low power consumption, excess electricity from photovoltaics can be used for hot water preparation almost all year round.

The heat pump's control system only activates it when sufficient solar energy is available. This not only reduces the CO2 footprint but also sustainably lowers energy costs.

Reliable function even at low temperatures

As an air/water heat pump, the aroSTOR extracts energy from the ambient or outside air – even at temperatures as low as -7°C. This allows the natural heat source to be used optimally in both winter and summer operation.

A particularly noteworthy feature is that the cool exhaust air can be used for room cooling, for example in building areas such as pantries. This versatile application option enhances the comfort and usability of the entire system.
