Description
The Daikin Altherma 3 M is a third-generation monobloc heat pump powered by R-32 refrigerant. Offered in outputs from 9 to 16 kW, it suits both new-build and retrofit projects.
Refreshed aesthetics
A sleek black horizontal grille hides the single fan, cutting perceived noise, while the light-grey casing blends discreetly into any setting.
