Description

Air-to-water Heat Pump hydro-split Daikin Altherma 4 H F EPVX10S23A9W EPSK10AW1

10 kW Tank 230 lt 400V

Daikin Altherma 4 H seamlessly integrates with existing radiators, delivering leaving water temperatures (LWT) of 70-75°C, even when the temperature outside drops to -15°C. It’s the ideal solution for retrofit projects and homes in need of reliable, high-performance heating.​

Engineered for efficiency, the Daikin Altherma 4 H features in-house designed and manufactured components, including a compressor, fan, and microchannel heat exchanger, all specially developed for this advanced heat pump. These advancements not only reduce energy costs but also ensure reliable operation year-round.​

With sound levels as low as 28 dBA at 3 meters, this is the quietest heat pump in its class – perfect for applications where quiet operation is specially required.

With a best-in-class heating capacity, the Daikin Altherma 4 H provides maximum output at -7°C ambient temperature, for the 55°C leaving water temperature required for older radiators.

This makes it a dependable choice for consistent warmth, especially in challenging climates. Operating down to -28°C, the Daikin Altherma 4 H ensures homeowners stay comfortable, no matter the weather.​
