====== Heating and Cogeneration ======
The three main uses of the heat in Switzerland are process heat, space heating for buildings and sanitary hot water. These are classified in two groups:
  * High temperature heat -> process heat
  * Low temperature heat -> space heating and hot water
The reason for this division is to avoid inconsistencies in the model such as supplying the process heat demand with solar panels. Each groups has a set of technologies that fulfill the heat demand. High temperature heat is supplied only by centralized technologies. Low temperature heat can be supplied by both centralized and [[d_heating_more|decentralized technologies]].

The difference between centralized and [[d_heating_more|decentralized technologies]] is the size. A centralized equipment is designed to supply heat for the big size industry or for [[dh_more_2|district heating]]. In the case of [[dh_more_2|district heating]] is necessary to have a net of underground pipes which deliver the heat (hot water) to the group of buildings, what is known as [[dh_more_2|district heating network]]. The [[d_heating_more|decentralized technologies]] provide heat only to a house or to a building, thus there is no need for a [[dh_more_2|district heating network]].
