The application guidelines provide you with basic application ideas
and recommendations on how to design eective layout patterns
for dierent rooms.

Meander pattern vs. snail pattern
Benefits
Meander pattern
• The meander pattern is easy to lay
• BasicRail™, BasicClip™ and BasicGrip™
systems can be used
• The meander pattern will distribute
heating less uniformly across the room.
In eect, some parts of the oor will be
warmer than others
Snail pattern
• Heating is equally distributed as supply
and return water runs adjacent. This
provides comfort compared to the
meander pattern.
• Requires more planning to lay
• Dicult to use BasicRail™
Pipe distance independent of pattern
type example:
Floor type: Wooden oor
Heat requirement: 40 W/m

Mean water temp.: 35 °C
Room temperature: 20 °C
= Pipe distance 200 mm CC

Small windows vs. large windows
Pipe distance
Small or no windows
Smaller windows do not need to be taken
into account as the downdraft is limited.
Example:
Floor type: Tile oor
Heat requirement: 40 W/m
2
Mean water temp.: 35 °C
Room temperature: 20 °C
= Pipe distance 200 mm CC
For information about your specic building,
please consult Danfoss.
Large oor-to-ceiling window
At larger windows the pipe distance
must be reduced in order to account for
downdraft from the windows.
Example:
Floor type: Tile oor
Heat requirement: 92 W/m
2
(at the window)
Mean water temp.: 35 °C
Room temperature: 20 °C
= Pipe distance, window 120 mm CC
= Pipe distance, rest 200 mm CC
For information about your specic building,
please consult Danfoss.
16 | Hydronc oor heatng applcaton gude
Bathroom
Suggested snail pattern for a typical
bathroom. Due to the requirement for
higher temperatures in the bathroom, the
pipe distance should be reduced.
Example:
Floor type: Tile oor
Heat requirement: 67 W/m
2
(at the window)
Mean water temp.: 35 °C
Room temperature: 24 °C
= Pipe distance, window 120 mm CC
For information about your specic building,
please consult Danfoss.
Kitchen
Avoid placing pipes under the kitchen
cabinets. If pipes are placed under the
kitchen cabinets, the temperature in the
cabinets will increase which is not optimal
if they contain food.
Example:
Floor type: Wooden oor
Heat requirement: 40 W/m
2
Mean water temp.: 35 °C
Room temperature: 20 °C
= Pipe distance 200 mm CC
For information about your specic building,
please consult Danfoss.

Kitchen Appliance
heating.danfoss.com | 17
Large rooms
Suggested snail pattern for a typical large
room.
Due to the size of the room the number
of circuits must be increased (in this
example to three circuits).
Example:
Floor type: Wooden oor
Heat requirement: 40 W/m
2
Mean water temp.: 35 °C
Room temperature: 20 °C
Number of circuits 3
