The Sizing program has a series of detailed questions regarding your project location. Based on your input data, the program provides you with an installation advice. When all steps are followed, an advice for a hot water installation will be provided. Besides roof build-in, roof build-on, flat roof frames and wall mounted sets you can also select wall hung collector sets in sizing a solar application.

For solar applications all relevant parts are included in the recommended installation. The program immediately displays the hot water requirements, specifying water needs in liters and the required energy in Gigajoule/year and kWh/year. In case of a solar application 2 options will follow, specifying the possible solar contribution and the expected annual savings from this installation.

We are currently working on updating our sizing tool to include the required Ecodesign information, i.e., product fiches and energy labels. Should you need that information, please do not hesitate to contact our partner Aquatep. They will gladly send you the information.
