By heat pump operation only, the outdoor unit delivers a leaving water temperature of 70°C at -15°C ambient temperature
By -15°C ambient temperature, the outdoor unit limits heating capacity loss
Outdoor unit extracts heat from the outdoor air, even at -28°C
The unit’s sleek design blends in with other household appliances.
Choosing for an R-32 product, reduces the environmental impact with 68% compared to R-410A, leads directly to lower energy consumption thanks to its high energy efficiency and has a 30% lower refrigerant charge
Guaranteed operation down to -28°C Daikin Altherma is suitable for all climates, even withstanding severe winter conditions with an operation range down to -28°C
