Daikin Altherma 4: The Future of Quiet, Efficient Heating with Natural R-290
Underhaching, March 2024 –
Daikin’s next-generation Altherma 4 H heat pump, arriving Fall 2024, showcases the brand’s latest innovation in sustainable heating. Designed in Europe for European climates, it uses natural refrigerant R-290, achieving peak performance even in extreme cold down to -28°C.
The new Altherma 4 is not just about power—it’s about peace. Thanks to a reimagined grille design and integrated acoustic insulation, the system operates at less than 35 dB(A) at night—quieter than a library. A specialized low-sound mode offers further flexibility, making it ideal for residential settings.
Performance meets sustainability with the aluminum microchannel heat exchanger, drastically cutting refrigerant use (only ~1.3 kg of R-290) while boosting thermal transfer efficiency. The result: A+++ energy rating and outstanding stability.
User experience is central to the design. The 5-inch touchscreen interface and MMI3 menu are intuitive, offering distinct views for users and installers. A built-in commissioning assistant streamlines setup for professionals, while end-users enjoy simplified access to daily functions.
Aesthetically, the unit stands out with a modern matte-black grille and muted grey casing—blending elegance with discretion. Behind the beauty lies robust safety architecture for R-290 use, including sealed PCB boxes, integrated gas leak detection with forced ventilation, frost protection valves, and more.
With Daikin Altherma 4 H, the brand reaffirms its mission: to lead the heating revolution with eco-conscious systems, smart design, and innovative engineering built for tomorrow.
