Short description
This standard serves planners, engineers and contractors as a planning and design guide for central heating units and house systems according to DIN 4747, which are supplied with direct or indirect connection from a heating water district heating network. For historical reasons, the procedures and regulations for the installation and operation of oil and gas heating systems are known to planners, engineers and contractors. Due to the increased requirements and the changed technology, district heating is now also an alternative for supplying areas with low heat density. Due to the requirement of the Energy Saving Ordinance (EnEV) not to exceed a prescribed annual primary energy requirement, the modern district heating supply with the use of combined heat and power (CHP) is gaining in importance depending on the primary energy factor.
