About the job
Do you want to reduce your CO2 emissions when heating? We help you with this and advise you on replacing your heating system with renewable energy.
Due to the combustion of fossil raw materials, oil and gas heating systems are among the largest contributors to CO2 and pollutant emissions. By using biogas or a heat pump, you can reduce these.
Biogas
Replacing natural gas with renewable and climate-friendly biogas significantly improves the climate balance. Our standard gas product contains 20 percent biogas, so your gas heating emits around 40 percent less CO2 than an oil heating system. You heat even more environmentally friendly with our products containing 50 or 100 percent biogas. Biogas is produced from organic waste such as green waste, sewage sludge or food scraps and is therefore considered almost CO2-neutral.
Heat pump
The heat pump uses free heat from the air, water or earth and converts it into heating energy in the form of heat and hot water. This eliminates the need to procure fuel, which leads to greater independence. Those who combine their heat pump with their own solar power become even more independent of external resources. A heat pump consumes much less energy than a fossil heating system and has low operating costs compared to other heating systems.
