How to Choose Devimat

Step 1

Select Devimat type

For timber floors use 100W/m² Devimat.

For concrete floors use 150W/m² Devimat.

If a room is part timber, part concrete, treat each area separately with separate controllers.

Step 2

Select Devimat size

Select a Devimat or combination of mats equivalent to the available free floor area, excluding all floor obstructions (i.e. bath, WC, kitchen uints).

For example if there is 4.3m² available, select the 4m² Devimat.

Step 3

Select controller

Generally only one controller will be needed, but for larger area the following applies:

Timber floors use one controller per 35m².

Concrete floors use one controller per 23m².
