SEMI-STORAGE AND STORAGE HEATING
ECOFLOOR CABLES AND MATS
Heating cables or mats in semi-storage systems are placed
in a layer of concrete 4–5 cm thick. The mat’s recommended
output wattage is 160 W/m 2 . Heat is accumulated for 16
hours a day at a time when electricity costs are lowest. The
accumulated heat is radiated from the fl oor surface not
only during the process, but also for a further 8 hours. One
effi cient solution is to divide the total desired heating system
70/30 between the fl oor heating and another source, such
as a convection heater or an ECOSUN radiant panel.

7 layer that is walked upon
Storage fl oor heating is a system that takes advantage of
cheaper electricity tariffs – usually at night. During this time,
heat is accumulated into the mass of the fl oor using ECOFLOOR
electrical heating cables or mats. Throughout the rest of the
day, the heat is gradually released from the fl oor to the room.
In storage systems, heating mats or cables are placed in a layer
of concrete 10 to 14 cm thick. The accumulated—stored—heat
is then released during the day into the area to be heated.
We recommend an output wattage of 250 to 300 W/m 2 for
ECOFLOOR mats used in this type of system. Eight hours of
low-tariff electricity should be used to accumulate the heat.
