Is the heating load calculation also suitable for other heating systems?

The simplified method for determining the heating load can generally also be used for other types of heating systems. However, the applicability and accuracy of the method depend on the type of heating system and the specific requirements of the building.
​
There are certain factors that need to be considered when designing heating systems, which can vary depending on the system. For example, the heat output of a heat pump may differ from that of an oil or gas heating system.
