HEAT PUMP AIR 406-420
Air-to-Water Heat Pump
The most quiet air-to-water heat pump NORD DUCK AIR 400 with high efficiency of 4.9 COP (Heat Pump Coefficient Of Performance).
Effective and quiet
Effective and quiet AIR 400 is equipped with a completely new, more efficient and even more reliable compressor, an electronic expansion valve and an updated fan design. This makes the heat pump the most efficient (4.9 COP) and the quietest air-to-water heat pump.
New design
This best-selling air-to-water heat pump is also endowed with a new design that allows you to connect various equipment to it.
Air is clean and full of energy
AIR 400 is easy to install, takes up little space and does not require well drilling at all. Instead, AIR 400 takes energy from the air and converts it into hot water and heat for your radiators and floor heating systems.
Power, when it is most needed
AIR 400 lowers heating costs by up to 70%, provides heating at an outside temperature down to -22 ° C and heats hot water up to 65 °C.
More power and longer service life
AIR 400 is equipped with automatic defrosting system, which reduces the need for defrosting to a minimum. Due to this the system produces more heat, provides more power and a longer service life.
No freezing over!
Under many heat pumps, a condensate freezes over and turns into a whole block of ice. It is not an issue anymore. The standard model of the new AIR 400 has a condensate drain tray with a built-in heater.
Hot water and Energyflex
AIR 400 functions best with the flexible multi-tank system BASE i250 or BASE i550 Pro for controlling both the heating and hot water systems. Thanks to the available special connectors, you can additionally connect a solar collector, a water-jacketed stove or a swimming pool.
Leave your old boiler behind
If you want to keep your old trusty beast in the boiler room – no problem. AIR 400 with Logic Pro Control can also function together with an existing electric-, gas-, oil- or solid fuel boiler.
