供暖 (gōng nuǎn): Cung cấp sưởi ấm (trong một tòa nhà)

Winters in the north are very cold, so the government starts supplying heating to residential buildings in November and continues until March of the following year.

The heating pipes in our neighborhood broke, and it's as cold as an icehouse at home. The property management said it would take three days to repair.

Many cities in the south don't have central heating. In winter, it's even colder inside than outside, so people have to use air conditioning to keep warm.

Coal prices have risen this year, increasing costs for heating companies. Residents are worried that heating fees will also go up.

This newly built residential area uses geothermal heating, which is both environmentally friendly and energy-saving, and has been well received by many homeowners.
