Vaillant aroTHERM plus 3.5kW

Vaillant’s aroTHERM plus air source heat pump provides heating and hot water from renewable energy, making it perfect for both new build and retrofit properties that demand low running costs, high efficiency, and an environmentally friendly solution.

Offering a future-proof solution that is both powerful and environmentally friendly, the new aroTHERM plus uses the natural refrigerant R290 to achieve higher flow temperatures of up to 75°C. Suitable for all applications, this air source heat pump can use existing radiators and operates down to -25°C.

The aroTHERM plus can be tailored to the properties needs with a choice of indoor units.

The uniTOWER is an integrated 190 litre cylinder with hydraulic components which can easily provide sufficient hot water for the needs of a family of five, including the use of rain showers. Thanks to its space-saving dimensions, the system is the perfect choice for new buildings. Installed indoors, the uniTOWER is about the size of a fridge freezer and saves valuable space in the room where it’s installed.

In the case of higher hot water demand, the aroTHERM plus can be used together with a wall-mounted hydraulic station and a wide range of accessories, including the uniSTOR heat pump cylinders and buffer tanks.
