If the heat pump is operated with ecologically-friendly power (e.g. hydropower, photovoltaics, etc.), the entire energy generation process is completely free of emissions and is CO2-neutral. This means that natural resources will still be available for us to use in the future.
Extremely efficient: heat and energy from nature are available for free – an advantage that pays off: 4 x environmental energy + 1 x electrical energy = 5 x heating energy
