Heating systems (Intro)

Heating systems produce heat for heating and hot water, through converting energy sources such as oil, gas, wood, district heating, electricity or free environmental heat into useful heat. Depending on the type of energy source, heat generation produces different amounts of CO₂ emissions: the combustion of fuel (oil and gas) causes a lot of emissions, while environmental heat from the ground, ambient air or groundwater is CO₂ neutral. The CO₂ intensity of district heating and electricity depends on the production, i.e. whether the heat or electricity is generated with renewable energy sources.
