Last updated: 2015-10-20 15:49. District heating cuts down the work for the individual home owner compared to other heating systems. District heating relieves you of the work on your own boiler: no chimney sweeping, no firing of the boiler and no topping up with fuel. Heat is generated in a thermal plant and is distributed District Heating System. DHS involves the combustion of biomass feedstocks in a single facility to produce steam, which is subsequently forced through a network of pipes and used to heat buildings (Bauen et al., 2009).

Working fluid is water. It is connected to the STTS through a heat exchanger located within the Energy Centre. District heating is an environmentally friendly and energy efficient heating supply that enables a green future with substitution to renewable energy. DISTRICT HEATING SYSTEM District heating is the concept of having one or more central heat sources instead of individual boilers. The heat is transported from the central heat source through a network of underground pre-insulated pipes to each building. District heating, also sometimes known as a heat network, is an engineering system whereby heat is generated centrally and then distributed through a network of pipes to many different buildings, offices, factories or other facilities. District heating and cooling systems By ENGIE - 11 February 2013 - 12:00 ENGIE operates 320 heating and cooling systems around the world in response to the long-term comfort needs (heating and air-conditioning) of both public and private sectors, at the same time as protecting the environment.

The district heating system Optimal protection of a district heating system is not very different from the way other types of installations are protected. However the focus lies mainly in the measurable and isolated components taking into consideration the risks of having bacteria and sludge in the system. District heating system is a thermal energy network that supplies hot water by means of insulated pipes to serve commercial, residential, and industrial energy needs for space heating, air conditioning and domestic hot water (DHW).
