The Energy Efficiency Services (SEE) of Saunier Duval have developed an effective but simple tool that allows to calculate, via Internet, the budget of an Integral Energy Efficiency system for Heating, Air conditioning and Sanitary Hot Water in single-family house, to be used by all people interested in installing an high energy efficiency system.

In order to perform the calculation, it is only necessary to indicate a minimum of data of the house, such as the habitable surface (m²), the number of people, the type of system (heating or air conditioning), the use of thermal solar energy for sanitary hot water (yes/no), and the geographic zone (warm, cold/warm or cold).

The systems include: condensation boilers, air-water heat pumps, radiating ground (heating/refrigeration), temperature regulation systems and thermal solar energy for sanitary hot water among others.
