A precise heating load calculation formula is essential for the optimum dimensioning of your heating system. The heating load defines the amount of heat required to maintain the desired room temperature, especially on cold days. The basic formula is:
Heating load (W) = transmission heat loss + ventilation heat loss
The transmission heat loss takes into account the heat loss through the building envelope, while the ventilation heat loss takes into account the heat loss through air exchange. An exact calculation of the heating load ensures that your heating system is neither oversized nor undersized, which optimizes both energy consumption and operating costs.
Your advantages at a glance:
- Efficient heating system
- Reduced energy costs
- Comfortable indoor climate
- Longer service life of the heating
