The heating method of apartment houses can be largely divided into an individual heating method and a centralized heating method.

The individual heating method is a method in which heating and hot water are supplied to each household by a boiler provided for each household, and each household has an advantage of supplying as much heating as desired when desired, but the boiler is in contact with the living space of each household. There is a disadvantage in that noise occurs during operation, and when a user needs, the boiler is operated to heat heating water or hot water, and a delay time occurs until sufficient temperature of heating and hot water is supplied.

The centralized heating method is a method in which heating and hot water are supplied to a plurality of households by a main heat source, and there are a district heating method for a specific area and a central heating method for an apartment complex such as an apartment.

In the centralized heating method, there is no need to separately manage the heat source for supplying heating and hot water in each household, and the user has the advantage of being able to immediately receive heating and hot water at a temperature set in the central system if necessary.
