2 General information
The ECdry oor heating system consists of a
foam/carpet heating element with heating
mats inside. The system must always be con-
trolled with a ECtemp, as it is an important
part of the safety and overheating protections
system.
The ECdry oor heating system can be used
under wooden oors such as parquet and
laminate. Please check the specications
with your supplier of these products.
ECdry has been tested and approved with
ooring materials with insulation values
from 0,07 to 0,18 m² K/W.
For best performance of the oor heating sys-
tem, keep the insulation value from the ECdry
heating unit to oor surface as low as possible.
The ECdry oor heating system has been
developed to the dry application area for
underoor heating.
It is applicable for wooden and concrete
oor constructions with the two output
ranges 55 W/m² and 100 W/m².

The maximum thermal resistance be-
tween the ECdry element and the room is
0,18 m² K/W as shown in the table below.
The ECdry oor heating system is for indoor ap-
plications in dry rooms only. As with any other
underoor heating system, it will be most
eective if the underoor is well insulated.
The following directions will guide you step-
by-step through the installation process. Please
read the directions and the safety precautions
before you start the installation process.
