Yes. Shaanxi has underfloor heating, and the heating area using geothermal energy in Shaanxi Province reaches 34.45 million square meters. Shaanxi, called "Shaan" or "Qin", is a provincial-level administrative region of the People's Republic of China, whose provincial capital is Xi'an. It is located in the hinterland of China, in the middle of China. The Yellow River borders Shanxi and Henan to the east, Ningxia and Gansu to the west, and Sichuan, Chongqing and Hubei to the south. It borders Inner Mongolia to the north.
If there is a draft and the underfloor heating is not turned on, it will freeze permanently.
If you just open a small opening and turn on the underfloor heating, this won't happen.
It is recommended to open the window a little smaller, as long as there is traffic, and the underfloor heating should not be turned off. Otherwise, your interior pipes could geand become damaged.
Be careful!
