Does Hebei province use air conditioning province or floor heating province for winter heating?

In terms of operating costs, let's first calculate:

Air conditioning: assume that the total room area is 100 square meters, and the single room is 20 square meters. A single room needs to be equipped with an air conditioner of 1.5P, and the actual electricity consumption per hour is about1.2kW. Assuming that the car will be driven only when it gets home, calculate 12 hours. Single room daily electricity consumption 14 kwh. Suppose the electricity charge there was once in 0.6 yuan, and the actual cost of a single room was around 9 yuan every day, less than 300 yuan a month. All rooms add up to about 1 1000 to 1 1000 in January (it should be impossible to open it completely).

Wall-hung boiler: According to relevant data, the daily gas consumption of 100 square meter for 24-hour heating is about 9- 15 cubic meter (related to use time, set temperature and surrounding environment). Suppose you only drive at night, then the actual gas consumption may be around 10 cubic meter. Suppose your gas bill is one cubic meter in 3.5 yuan, which is 35 yuan. Then it will be about 1000 yuan in a month.

Secondly, from the point of use comfort:

The heating of the air conditioner is blown down from above, and the temperature in the room is always warm and cold, giving people a very uncomfortable feeling. And if your room is high overhead, it may even happen that the measured temperature on the roof reaches 30 degrees, while the temperature near the ground is only 4-5 degrees. This is the source of discomfort and cold feeling when using air conditioning in winter in the south.

Wall-hung boiler: If you use the floor heating terminal, congratulations, the heating terminal you are using now is the most comfortable among the existing heating terminals. When the ground temperature is about 20 degrees, the height temperature to the human head will be kept at about 18 degrees, which will never be wasted like air conditioning, and a lot of heat will accumulate on the roof level.

Finally, from the use environment:

The energy efficiency ratio of air conditioners is the highest among existing heating equipment. When the outdoor temperature is kept above 5 degrees or even close to 10 degrees, the energy efficiency ratio of the air conditioner is above 2.6, that is to say, if you spend 1 yuan, you can generate heat equivalent to 2.6 yuan money. However, it must be clearly recognized that when the outdoor temperature is lower than 5 degrees, or even lower than 0 degrees, the energy efficiency ratio of the air conditioner drops sharply to below 1 and operates below 0 degrees. As long as it is slightly damp outside, the air conditioner will frost immediately, and the control effect is close to zero at this time. Therefore, air conditioning is only suitable for heating in winter in Jiangnan area. As for the combination of the Yellow River and air conditioning for heating in winter, it may be a joke and purely psychological comfort.

The wall-hung boiler uses gas to generate heat, so there is no problem that the outdoor temperature affects the heat source. However, when the outdoor temperature is as low as MINUS 25 degrees or even MINUS 40 degrees, the flue gas produced by the wall-hung boiler will condense in the air for a long time, so attention must be paid to it when installing.
