Overview

aroTHERM Split offers the ultimate heating and hot water comfort for all types of buildings and heating systems. The range of outputs available means there is a solution to suit most UK homes. Designed for quick and flexible installation, the aroTHERM Split is delivered pre-filled with refrigerant with enough to support an installation 15 metres away from the building.

Depending on the property, aroTHERM Split can be installed in the garden or mounted directly onto a wall or roof. Vaillant offer the perfect fittings to complement any type of installation.

From just three metres away, the acoustic pressure level for aroTHERM Split is 35 dB(A), meaning it is an extremely quiet solution that can be installed into densely packed terraced housing communities with no problem.
