Semi-accumulating system
c) Regulation

For regulation, use one of FENIX’s available thermostats. For accumulating and semi-accumulating
floor heating, a thermostat with a floor probe is required.
d) Accelerating the warming of the heating floor

The heating floor may be put into operation after the concrete hardens thoroughly (i.e., after 4–6
weeks).

On the first day, set the temperature of the floor to be the same as is the temperature in the room
(maximum 18°C).

In the following days, gradually increase the temperature of the floor by 2°C per day up to 28°C.

Maintain the floor temperature at 28°C for three days.
 Then reduce the floor temperature by 5°C each day until reaching the initial temperature.

Afterwards, it is possible to set the floor temperature as needed and start normal operation of the floor
heating.
4. Heating outside areas (anti-freezing protection)
a) Dimensioning
If the heating is intended to be used on open areas with soil as a base and on thermally insulated
surfaces, set the flat output to 200–300 W/m
2 . If the heating is intended to be used on surfaces that are
not thermally insulated, set the output to 250–350 W/m 2 . The value of the output depends, among other
things, on the depth to which the heating system is installed. That means that the closer the installation
is to the surface, the lower the output needs to be within the recommended range. If installed into fine
washed sand, the installed flat output must not exceed 300 W/m
