The objective of this case study is to compare the environmental impact of a heating system using a gas conventional boiler and other using electrical heaters at the point of use. The simulations were made taking into account the conditions for a normal house and a low energy house. Several electricity generation mixes were also used in order to assess the impact of electrical heating in different countries.
The results show that electrical heating has great advantages when clean electricity generation is in place, e.g. using renewable energy sources or nuclear energy.
