How many hours does the hotel steam boiler run on average every day?

The heating load in winter is calculated as 60 watts per square meter, 120 rooms × area of each room = total power (watts). This wattage is the wattage of the boiler, but if the boiler has other uses, such as cooking, boiling water and bathing, the power should also be counted together.

According to the electricity meter in room 120, the heat exchanger is ok.

The steam boiler runs for almost 20 hours a day because you need to keep warm.
