Heating is the process of supplying heat to rooms in order to maintain the optimum temperature in them. This ensures occupant comfort and protects the building from the negative effects of low temperatures.
Heating is realised through various systems. For example, such as central heating or local, radiator, surface (floor, wall, ceiling) or mixed. Heat sources can be solid fuel boilers (e.g. coal, wood, pellets), gas, oil, heat pumps, electric heating or renewable energy sources such as solar collectors. The choice of heating system depends on type of buildingavailable energy sources and economic and ecological requirements.
