8 steps to control of heating systems

Heating a home has always been and still is a basic human requirement. This requirement enables us to live and work in locations with low temperature. In the beginning the solutions were simple. An open fire on the floor of a tent or a simple hut, made it possible to survive in a hostile environment. As civilisation developed there was migration from the countryside to the towns and cities and into bigger and bigger houses, creating a requirement for more elborate heating systems.

This requirement stimulated technical development, but also created a problem, namely the use of a finite resource (fossil fuels) with the resulting pollutions from the burned fuels.
