The all-new aroTHERM plus is Vaillant’s latest evolution of its flagship R290 air source heat pump, said to represent a significant leap forward from its predecessor.
Improvements to the aroTHERM plus see the new range take heat pump efficiency levels even further, offering COP figures of up to 5.39. It includes Vaillant’s Sound Safe System, resulting in an improved sound performance from 44 dB(A), suiting it for residential installations.
The new heat pump also provides greater install flexibility, as it features an advanced space function that, when activated, allows installation almost anywhere around the property, breaking free from the fixed space requirements of the previous generation and delivering installation flexibility and convenience for installers. This helps make the most of outdoor space and gives more options for the heat pump to be fitted in a location that works for them.
The interface features an intuitive semi-touch display, giving homeowners and installers premium control over their heating system.
When registered through myREWARDS, Vaillant’s loyalty platform, the new aroTHERM plus comes with up to a seven-year guarantee when fitted with a Vaillant uniSTOR high recovery cylinder – providing installers and homeowners with peace of mind.
