Kermi x-change air/water heat pumps with quiet operation

x-change® air/water heat pumps

As simple as they are clever: The x-change heat pump is responsible for generating heat in the “Kermi system x-optimised”. Saving resources, this heat pump removes thermal energy from the surrounding air and converts it into heating warmth. Ideal for a single-family house – in a new-build and when renovating. Suitable to be set up indoors and outdoors.

About the heat pump size:

Your heating engineer will advise you on selecting the “right” heat pump size. It is important to think about your individual situation and energy demand in advance. The decisive factor is always the respective heating load of the building. This heating load, the total heat demand of a building, does not just depend on construction details, such as insulation and isolation, but also on the size of the household, the individual heat demand, and also on the domestic hot water demand. The average fuel sales in the last three years applies here as the first indicator for the level of the heating load.

Modulating x-change® dynamic AW I air/ water heat pump for indoor installation

The x-change dynamic heat pump is highly convincing thanks to its extremely efficient, virtually silent operation. This is made possible by a new innovative EPP housing design, with the latest radial fan technology including whisper mode and a large modulation range for the compressor, fan, and charge pump. The high quality lower part of the housing combined with the multi-layer insulation and triple sound-proofed cooling circuit guarantees very low sound emissions.

The x-change dynamic is equipped with the x-center x40 controller.

Modulating x-change® dynamic AW E air/ water heat pump for outdoor installation

The x-change dynamic heat pump is highly convincing thanks to its extremely efficient, virtually silent operation. This is made possible by the latest axial fan technology including whisper mode and a large modulation range for the compressor, fan, and charge pump. The high quality casing with robust stainless steel covering guarantees, together with the several-times insulated and triple sound-proofed cooling circuit, minimum sound emission.

The x-change dynamic is equipped with the x-center x40 controller for wall installation.

x-center control

For an optimal result. And a regulated process.

The x-center controller controls the Kermi system x-optimised and guarantees efficient and resource-saving operation of the heating system by regulating the flow temperature. Equipped with a clearly arranged display, the x-center controller is proving to be extremely user-friendly in the process. We intentionally kept it easy to use and decided in favour of a intuitively identifiable screen design. Thanks to this user-oriented user interface with clear menu guidance, it is straightforward and really easy to use the Kermi system x-optimised. This means the device can be controlled without any problems after being given brief instructions when the system is commissioned.
