The Waterkotte Basic Line Ai1 Geo is a ground source heat pump which doesn’t need to hide. It uses the geothermal energy to heat the house in the winter and can additionally be used for cooling in the summer. The modern technology with an impressive COP value of 4.8 promises highest efficiency and thus an optimal energy balance. To match the design outside, the control is done via a large format display. Being only slightly bigger than a refrigerator, the Ai1 Geo can be positioned everywhere in the house, none the least because of the efficient noise insulation.
