According to the manufacturer, the new Alpha Innotec heat pumps require less than half a square meter of floor space. The units achieve flow temperatures of up to 70 degrees Celsius.
Four space-saving ground-water heat pumps for single-family homes: New models in the Subrox series from Alpha Innotec offer 8, 9, 13, and 18 kW of output. According to the manufacturer, the geothermal heat pumps require less than half a square meter of floor space. The hydraulics are reportedly already largely integrated. The units are designed to reach flow temperatures of up to 70 degrees Celsius for heating and hot water.
The provider states that this technically compact solution is suitable for new construction as well as renovations and for replacing existing heating systems. The heat pumps use the refrigerant R 290 (propane).
In addition to basic models, there are versions with an integrated hot-water storage tank with a capacity of 178 liters. A passive cooling function is available as an option. Depending on local conditions, heat sources can include geothermal probes and ground collectors, as well as groundwater and wastewater. For buildings with higher heat output requirements, multiple units can be combined.
Alpha Innotec is a brand of “ait-deutschland GmbH.” The Berlin-based company is owned by the Swiss firm Snow Cliff AG, headquartered in Wolfhausen. Snow Cliff, in turn, is a subsidiary of the Swedish group NIBE.
