Water/water heat pumps
for indoor installation
Energy from Groundwater
An inexhaustible resource. Water/water heat pumps use groundwater as a heat source at any time of the year. The only requirement: the groundwater taken from the well must be available in sufficient quality and quantity. At the same time, it must be checked in advance whether there is approval from the responsible water authority.

It couldn't be more efficient.
Whenever you want the most efficient system for cooling and heating, our water/water heat pumps are just right. Since the groundwater temperature is constantly around 10 °C even on the coldest days, heat generation does not have to compensate for climatic fluctuations. So it's always cozy and warm in winter - and in summer you can cool passively in a particularly energy-saving way.
The quality: robust. The result: long-lasting.
Simply impossible to get small: An innovative spiral heat exchanger made of corrosion-free stainless steel makes our WI heat pumps particularly robust. Therefore, they can be used almost regardless of the water quality.
Green Energy
The heat pumps in the WI series save a lot of electricity and have therefore more than earned the A++ energy label.
From anywhere. At any time.
Convenient Controls
With the Dimplex Home app, the heat pump control can be accessed at any time and from anywhere.
With the intuitively designed app interface, the most important settings on the heat pump, such as summer/winter switching or setting the hot water temperature, can be easily made. In combination with the intelligent room temperature control, the temperature for up to 20 rooms can also be set depending on the user via the app and even combined with weekly programs.
WI TU: The most efficient.
Highly efficient water/water heat pumps for heating outputs from 10kW to 22kW. This corresponds to heated living areas of 200m 2 to 500m 2 . Single- or two-family houses or small apartment buildings can be heated and cooled without any problems. But there are also options for apartment buildings. The WI TU from Dimplex can also be flexibly expanded. For example, in combination with oil and gas heating systems (bivalent fossil) or log stoves and solar thermal systems (bivalent renewable).
