Definition - General information
Tele-heating is defined as the provision of heating with a special network of insulated pipes carrying hot water, which is heated in boilers, usually in thermoelectric plants, far enough away from the consumption area. It is the heating of the buildings of a city or part of the city from a central burner rather than individual ones.
The heating of water is by burning gas, oil or coal (lignite) in a plant mainly producing electricity and thermally or vice versa.
The heat required to heat district heating water comes from the steam used in the plant and in particular from the end of the process. Steam has a temperature of 120 ° C-140 ° C. This hot steam heats the water used in the district heating, passing the pipes it is transported with, next to the steam - that is to say a heat exchanger. At the beginning of the flow, the water has a temperature of 100 ° C and the return of 20ο - 40οC.
The first small-sized T / C installation in Greece started in Ptolemaida in 1960, heating the PPC settlement in the suburb of Eordea by Ptolemaida.
Today, the T / C facilities have the cities of Kozani, Ptolemaida, Amynteou, Filotas, Megalopolis and Serres, which use the thermal load of neighboring thermal power plants.
Tele-heating in Kozani
More than 75 million euros (currently approximately 110 million euros) have been invested since 1992 in the district heating of Kozani, which has been successfully operating since 1993, heating approximately 25,000 apartments, to a total of 4,900 , About, buildings. This money came from European programs, And own resources of DEYAK and resulted in:
• The steam installations from the III / V and V units III of the SA / Dimitriou
• High-end boiler room
• Transport and distribution pumping stations
• Supply and distribution network, with a total length of more than 450 pipes kilometers.
Tele-heating: Economy and protection of the environment
The operation of T / C benefits both Kozani and its inhabitants as well as our national economy, because
The quality of life of residents, which enjoy a cleaner environment, free from the chimneys of oil and oil-fired central heating, have burdened the already impoverished atmosphere of our PPC activities.
The inhabitants of Kozani spent 65 million euros less heating, increasing their disposable income accordingly. In the future and every year this amount will be about 10 million euros.
Foreign currency was saved due to non-consumption of 380,000 tons of heating oil. Every year 32,000 tons of heating oil will be saved.
New jobs were created, directly and indirectly, and new impetus was given to the commercial and craft activity of the city.
Since 1994 there have been 40 employees working on the system, and it is estimated that more than 100 people per year have been employed in the construction of the project since 1993.
There is the possibility of further development of the area with multiple activities in the primary and secondary sectors, such as greenhouses, dryers etc.
