Heating
Get your best headphones ever
In the northern region of China, heating is required during the winter and in the northernmost
parts, heating is required most of the year. Heating is provided in several ways in these parts. For
example, in Beijing, residential buildings may have a coal-fired boiler to heat the water, which is
then distributed in the building and providing heat through radiators.
Another common option is the use of heat pumps. These account for 80 percent of heating and
cooling systems sold in China. However, the heat pump is not optimal for the coldest regions.
These options are normally used when the public heating system is not available. The public
heating is a service to the residents during winter and is known as district heating.
District heating was adopted in China in the 1980’s and they had the benefit of being able to use
modern technology from start. In two decades, the development covered 1,4 million m² living
area and about 600 cities had connected to the district-heating scheme. Today that number has
grown to over 700 cities where district heating is being used [8].
The main fuel source used in the district heating plants in China is coal and compared to using
individual coal fired boilers in buildings this system greatly reduces the CO2 emissions. Another
fuel that is widely used is natural gas.
A typical configuration of the system is that the water is heated in the heating plant and
transported by pipeline to residential buildings that are equipped with radiators. CHP plants have
been developed to increase energy efficiency further, where the bi-product (steam) that is
normally wasted is used for electricity generation.
Until recently, the price of heating has been based on residential area, but meters are being
installed at the heating plants as well as in the apartments in order to monitor the actual energy
consumption. Another improvement is that temperature control units will be installed in each
individual apartment
