Is there anyone who lives in the Yangtze River valley and uses jman wall-hung boiler to keep warm?

My home is in the north. Like a classmate upstairs, I use ariston's wall-hung boiler and radiator to keep warm. Wall-hung boilers can also be used with floor heating, which is more comfortable in winter. However, LZ is in the Yangtze River valley, and it is still possible to use radiators. Wall-hung boilers can supply water and heat at the same time in winter, and turn off heating in other seasons, only supplying water. If it is used for heating, it is more expensive. In winter, it is about 1 1,000 yuan of natural gas (because I am afraid of cold, the boiler heats 24 hours a day, and the temperature is low during the day and high at night). The other nine months, cooking with hot water, probably in 200 yuan. Wall-hung boilers are generally in standby state, and the gas is always on. As soon as Longtai is turned on, there is hot water. Every 24 hours, the boiler will circulate the water in the water pipe to prevent freezing in winter. I think the refrigeration boiler LZ said must be closed and installed outdoors.
