Underfloor heating pipe spacing: how it affects performance

The spacing between underfloor heating pipes directly affects the temperature distribution on the floor and the output the system can deliver.

Smaller spacing

Provides a more uniform surface temperature and higher thermal output per square meter, but requires more piping.

Larger spacing

Reduces pipe length and costs, but may increase temperature variations on the surface.

There is no single spacing for all areas

The choice depends on the heating load, the type of flooring, and the supply temperature.

Proper design

Distances are determined for each room individually and should not be chosen empirically without calculation.
