Chen Xin was only worried that the boiler might not meet the heating demands, but in the city, this issue had already become one of the primary problems faced by the shelters, posing severe challenges to the survival of the survivors inside.
The boilers inside the shelters are coal-fired. Compared to oil-fired boilers or other heating methods, these boilers have low operating costs and mature technology. However, they were gradually phased out before the disaster due to environmental concerns, and their thermal efficiency is not as good as new gas boilers.
But due to their mature technology and relatively simple maintenance, coupled with the ease of storage and transportation of coal, coal-fired boilers became the most suitable heating equipment after the disaster.
After all, whether using natural gas or oil, the maintenance costs of new boilers, whether before or after the disaster, are higher than those of coal-fired boilers.
