Simply tap the ground.
The SI 6TU is a highly efficient brine-to-water heat pump that uses the thermal energy from the ground and can be installed easily indoors. With 6 kW heat output, it is the most efficient solution for newly built single family homes with a living area up to 140 sqm. Flexible expansion options are available thanks to the universal design. Domestic hot water preparation, for example, and the combination with an oil or gas boiler. Different heat distribution systems (radiators, underfloor heating, fan convectors) can also be connected here.
