Spec Pro product selection tool

Spec Pro® is our innovative water heating specification tool. Completely free and easy to use, Spec Pro® calculates the hot water requirement for your project based on some basic input data to provide you with recommendations on the most suitable product(s) and the capacity required to meet the hot water demand.



Whether your project is for a domestic dwelling or a commercial environment such as a school, hospital, office block or sports centre, Spec Pro® works by inputting the number of basins or showers in use within a core (a zone, a room or a floor of a building), along with data for the duration of peak demand and flow rates, for instance. Spec Pro® can account for different heat sources, whether it is direct electric, indirect via a boiler or a solar thermal installation.

Our Spec Pro® software can calculate and make recommendations for unvented cylinders from 70 litres up to 2,500 litres, solar cylinders, point of use water heaters, boiling water products, chilled drinking water equipment and hand dryers. In addition, the system features product specification information, images and CAD drawings, which can be emailed, downloaded or printed. Download our Spec Pro® software today to discover how we make specification easy.
