### 2.3.3. Specifying room data

Special attention must be paid to the most important data in relation to the system being designed, such as room temperature, temperature below, type of room that implicates maximum temperature of floor and reduced heat demand of the room, which after taking into account the FH contribution indicates the heat loss to be covered by floor heating. To ensure clarity of the drawing and results, enter the names of the rooms.

Maximum temperatures of floor surface determined on the basis of the selected type of room is one of the key limiting criterions of sizing a floor heating system. If you want to enter a maximum floor temperature other than the standard one (default), select “Other” in the “Room type” field, then select “Yes” in the “Display FH data” field and enter the required value for tfs/qfs max.

! The heat loss to the heated floor (partition) must be deducted from the heat loss of the room. This part of the loss will be covered by increased flow of the heating medium in floor heaters. Instal-heat&energy automatically determines the reduced heat loss provided that heating partitions are properly marked in the tables.

The “Wall type” data are important if there is a difference between the spacing of the heating zone from external and internal walls specified in the general data. By default wall is recognised and type is automatically assigned to it.
