Exhaust air pump RX35

RX35 is a highly efficient and easy to maintain heat pump with an award-winning user interface. It is suitable for houses of 60-120 m² (or 650-1300 ft²), it has high operating efficiency and is more environmentally friendly than previous models. It gives you by far the lowest total cost among the heat pumps available on the market, to name just a few of its fine qualities.

Low noise level

The RX series is available in three different sizes to match different needs. All of our heat pumps and cooling pumps use the new refrigerant R32 which allows for higher efficiency coupled with lower impact on the environment. Our new heat pumps in the RX series also measure significantly lower noise level than their predecessors.

RX35 gives up to 3.5 kW and has a 210 liter water heater. If you want to get the reverse function, cooling, an additional supply air unit is needed; T15. More information about this product can be found here.

* The power data at 20 (12) / 35 °C and 20 (12) / 50 °C is stated according to European standard EN255 without fans and pumps. The indicated temperatures 20 °C indicates air temperature for indoor air and (12) °C indicates the air wet temperature link.

** Delivered with 6 kW immersion heater. The immersion heater is adjustable to enable compliance with current Swedish regulations regarding newly constructed houses.

Note: When comparing with geothermal heat pumps the power consumption of the brine pump must be taken into account. A corresponding geothermal heat pump loses up to 10-20% input power and COP by pumping the refrigerant 100-150 meters up and down the borehole.
