### 6.3.3. HZ that covers only part of room

By default the heating zone covers the entire area of the room. This facilitates editing in usual cases. In unusual cases you can divide the HZ and remove those HZ’s, which are not necessary or you can using a non-standard spacing between HZ and the wall or draw HZ’s in the room manually.

¨ To create a HZ that covers only part of room:

1. Insert the HZ into the room (see 6.3).

2. Divide the original HZ in such manner that one of the new HZ’s covers the area intended to be eventually covered by floor heating, for example:

3. Delete the unnecessary HZ’s:

The method described enables creating any HZ with the shape of a convex polygon. In less complex situations, when it is sufficient just to move the HZ border away from the wall, you can use another method consisting in specifying a non-standard spacing of HZ from the wall.

¨ To move the border of HZ away from the selected partition:

1. In the project options (F7) in the “Radiant heating – floor heating” tab specify standard spacing of HZ from external and internal walls.

2. To specify a non-standard spacing for one of the walls, select the “Construction” layer and mark the wall from which a non-standard spacing of HZ is to be retained.

3. Specify the distance between HZ and wall in the “Spacing from wall” field. HZ area will be modified accordingly:

It is advisable to specify appropriate distances from walls before inserting heating zones into the rooms and editing them (e.g. dividing). If you change the distance between HZ and wall in rooms where HZ’s have already been inserted, the latter can be modified incorrectly, particularly in complex cases where several HZ’s border with one wall.

In a situation where the area not covered by heating is fragmentary and haphazard, use the “Occ. area w/o pipes [m2]” field in the HZ data and enter the desired value. To place the occupied area fragments in the drawing use graphical components and labels.

¨ To draw a HZ in a room manually:

1. Select “Heating floor (manual)”

2. Move to the drawing area and mark the first corner of the heating zone by pressing the left mouse button:

3. Insert all corners of the HZ to form desired shape. To finish inserting, press the right mouse button:

This method enables inserting heating zones of any shape and size.

! The quantity of materials for heating zones of any shape is calculated for the area covered by that HZ. Therefore such zones should be used in special cases only.
