How cold is winter in Huainan City, Anhui? Is there heating?

Huainan is located on China’s 0°C isotherm, so the temperature difference in winter is not big. It is much warmer than northern China, but colder than the south. Geography books say that the average temperature in Huainan in winter is between 0 and 12 degrees Celsius. According to data from the Meteorological Network, the average winter temperature in Huainan in the past three years has increased by 3°C compared with 10 years ago. At present, the only place in the city that has officially enabled winter heating equipment is the Huaihua Living Area in Tianjia'an District. Huaihua Living Area relies on the energy produced by Huaihua Group for self-sufficiency and uses water heating to heat the entire community in winter. Although heating equipment is also installed in newly built communities elsewhere, they have all been activated.
