Rehau's Online Tool Makes Heating and Cooling a Br

Rehau has been designing advanced radiant heating and cooling systems globally for over 30 years and has now made the design tools available online for installers and specifiers to make materials estimations, performance calculations and offer a comprehensive design service for their clients.

The materials estimation or "Quick Quote" identifies the Rehau components recommended for the project while "Performance Calculations" identifies the required water flow rates and temperatures to enable accurate sizing of pumps and an energy source. The full design service provides pipe layout design and individual circuit specifications for optimised installation and operation.

Also available on the design portal are online installation and design training modules, installation videos, Rehau Authorised Installer Network (RAIN) training registration, event information, product information and regularly updated references and case studies – everything the new and experienced installer, architect or engineer needs.
