Available energy sources for heating


The use of gas as a fuel offers many advantages: the technology is very efficient and relatively inexpensive to purchase. Gas can be perfectly combined with renewable energy and is very well suited for modernising old buildings. Find out more about the use of gas.

Solar energy

The sun provides us with free energy in unlimited quantities. This energy can be used for your heating system, thereby saving costs and protecting the environment.

Environmental heat energy

Ambient heat is found in the ground, groundwater or solar energy stored in the air. It is available for free and in unlimited quantities. Learn how heat pumps make efficient use of ambient heat and how you can protect the environment with this type of energy recovery.

Electricity – provides instant heat with little effort

Electricity can be used easily for heating and hot water preparation. This energy source is highly available and the installation effort and costs are low. Thus the conversion level is low too.
