A Heat Retention Calculation is a specific calculation using the individual plans supplied via architects engineers, designers and/or clients. This calculation arrives at the precise kilowatts that are needed to heat every room in the dwelling to a comfortable level, while using as little fuel as possible, thus saving energy. This calculation gives information for the correct sizing of the Heating Unit to be used. To sum up the calculation, a heat load calculation is the foundation of the heating system. It ensures that when the heating system is turned on you have a high-performing heating system that has low running costs. There is no over expenditure and no under or oversizing of any componentry of the heating unit and other heating equipment.
Construction or renovation projects for buildings raise the central question of what performance a heating system must provide. In order to determine the heating energy requirement, many values and building specifications must be taken into account. In addition to the size, the type of walls/ceilings/roofs/floors and the number of windows play an important role.
