Air to water heat pump with ventilation function
Even when temperatures outside are at their lowest, the outside air still contains enough energy to use for heating and hot-water provision.

Wood pellet heating
A wood pellet heating system uses the natural, renewable energy source of wood for fuel.
Solar energy systems
Solar collectors capture solar energy and feed it into the heating system via a heat transfer medium.
Comfort ventilation systems
The living space ventilation system does not have a heating function in the strictest sense but supplements the existing heating system in terms of home comfort and cost-efficiency.
Photovoltaics
Roof-mounted solar collectors convert solar energy into direct current.
