Why is the standard temperature for gas hot water boiler heating 18 °C

Because of the comprehensive environment, construction, and other factors, after every room temperature exceeds 18 ° C, the energy consumption increases by 20% for each additional degree. But it can't be lower than 12 °C. Hygiene uses 12 ° C as the lower limit of the building's thermal environment. Below 12 ° C, the body's metabolism will slow down, the subcutaneous blood vessels contract, the resistance of the respiratory mucosa decreases, and it is easy to catch a cold.

Room temperature is also called normal temperature or general temperature.

What is the standard room temperature? This is actually not clearly defined in China, and most of them are based on (23 ± 2) °C. The indoor temperature that is most suitable for people to live in is 16 to 18 ° C in winter and 24 to 26 ° C in summer. When the heating temperature exceeds 22 ° C, the indoor air will be abnormally dry, and thus affect the body's own body temperature regulation function, resulting in increased body temperature, vasodilation, increased heart rate, endocrine disorders and so on.

At the same time, the standard temperature of the heating of the gas hot water boiler is too high, which will also increase the volatile emissions of toxic and harmful gases in the decorative materials such as furniture, flooring and stone. Excessive temperature is more harmful to the body than if the temperature is too low.
