The heat pump has been ubiquitous, and not just since the German government's hotly debated Building Energy Act. It is regarded as the climate-friendly and energy-efficient heating technology of the future and is already being used successfully in numerous construction projects. Correctly calculating the heat load of a heat pump is essential if it is to provide comfortable temperatures.
But which factors are decisive for a correct result? And how high is the electricity consumption of a heat pump anyway? In this article, we provide a detailed overview of the key facts for a precise heating load calculation.
The most important facts in brief
The heat load calculation lays the foundation for correct dimensioning of the heat pump
Incorrectly designed heat pumps can result in higher operating costs
Software-supported calculation facilitates application in complex construction projects

How much heating load does a heat pump need?
The heat pump has established itself as a promising heating technology that promises both ecological and economic benefits. However, before implementation, it is essential to determine the heating load precisely. This value indicates how much heat energy it must supply to effectively heat a building.
This is because the heating output of a system is of crucial importance. It marks the amount of energy that a heating system must generate on cool days. All rooms in a building are included in this calculation.
