### 2.3.7. Analysis of calculation results and messages

After clicking on the “Next” button, calculations are done for the floor heating system and the tab with preliminary calculation results and error messages is activated.

The results are divided into groups assigned to manifolds, whereas manifolds assigned to one control circuit are displayed one after the other. Results for all HZ’s assigned to one manifold are displayed under the row with manifold label and separated by rows with labels of rooms to which the HZ’s belong. Zones heated by pipe feeds that belong to a given control circuit are displayed under the last manifold of that circuit. Rooms assigned to one manifold are listed in alphabetical order.

! The button to the right of the “T (B,b,p,r,VA)” field enables selection of pipe spacing other than the one determined automatically. After changing the pipe spacing, other result fields are amended correspondingly.

In the lower part of the results tab is the list of error, warning and hint messages with a yellow background. The rows or cells of the results table where error occurred are also highlighted in yellow. After indicating a message in the error list, the mouse pointer is positioned on the row that the message applies to.

The system is optimised in thermal and flow terms in order to attain the required output of floor heating in each room and to balance the manifold hydraulically.

In the design method applied, at first one heating circuit should be inserted in each room where radiant heating is to be used and the program should adapt to the specified conditions. After moving to the calculations stage, the suggestions proposed should be checked and HZ’s divided, if necessary.

It may, however, occur during calculations that balancing of the system is not possible. The user is notified about this and a suggestion is displayed how to amend data. You should then go back to the editor and divide the HZ into the specified number of circuits.

In typical detached houses dividing circuits may not be at all necessary or it may be necessary for a few HZ’s only. However, when designing facilities of larger surface area, such as industrial buildings or temples, the required minimum number of divisions is indicated.
