IWA - F. Riehle GmbH & Co KG is the market leader in slide charts and wheel charts. We are putting this marketing instrument on the market now as iPhone App at the request of our customers.
With the IWA Heat-Demand-Calculator for iPhone, iPad and iPod Touch you are able to determine the heating load of a building quickly and precisely. The detection of the heat demand of a building and its rooms is an essential condition for the planning and dimensioning of your heating and air conditioning system.
This calculator is based on the requirements of EN DIN 12831 and an especially generated calculating procedure.

This lite-version of the IWA Heat-Demand Calculator is limited to calculate the heating load of a single room and the protocol can not be sent via email.
