A Heating system (or heating system) is a system that is used for heating z. B. serves a building, d. H. the supply of heating energy in order to achieve a sufficiently high room temperature. There are different types of such systems:

  • In Central Europe, most buildings are equipped with central heating, which includes a central heat generator and a heat distribution system (almost always with circulating hot water). Typical heat sources are boilers (e.g. with oil, gas or pellet heating) and heat pumps (→Heat pump heating). (Active) solar heating is only rarely used.
  • Some houses also have floor heating systems that supply individual floors or apartments.
  • It used to be customary to heat rooms individually - usually with individual ovens, e.g. B. were fired with coal or heating oil.

The greatest heating output is required on the coldest days of the year because this is when the building loses most of its heat to its surroundings. The heating system must compensate for this heat loss, provided it has not already been compensated for by other heat gains (especially solar radiation through windows and heat dissipation from devices and people).

The need for heating power and heating energy (heating demand) can be reduced dramatically by good thermal insulation of the building. A well-insulated single-family house comes in Central Europe on the coldest days with z. B. 5 kW heating output, while an uninsulated house of the same size can require more than 30 kW. In the passive house, the conditions are optimized in such a way that a significant supply of heating energy is only necessary on a few (particularly cold and cloudy) days.
