HEATING MODE
Depending on the thermal insulation standard, you require
a heating power between 30 and 200 W/m² living space. The
LAVA
®
infrared heating has a very large radiation component
and a very small convective component of the heating power.
For reasons of safety, the surface temperature is max. approx.
120 °C, therefore the total power of the devices is limited.
This is the reason why these devices can only be applied as an
exclusive heating in houses with a very good heat insulation.
The LAVA
®
infrared heating by ETHERMA mainly heats solid
objects and, only to a lesser extent, directly heats the room air.
Therefore, these devices are ideal for additional temperature
control. In order to achieve the same feeling of comfort as with
a convection heating, the room air temperature can be reduced
by approx. 2–3 °K. Each degree that the heating is reduced can
save up to approx. 6 % of the heating costs, depending on the
heating performance and thermal insulation standard.
Only if the room is actually used, the LAVA
®
infrared heating is
additionally switched on and the radiation takes over the task
of heating the persons. Depending on the size of the device, the
LAVA
®
infrared heating requires a certain time until the oper-
ating temperature is reached. Only then the radiation can take
its full effect.
MAINTENANCE AND CARE
The LAVA
®
infrared heating is designed so that it gives off its
heat via the surface in the form of radiation. The device does
not contain any parts requiring special maintenance. In order
to service your infrared heater, we recommend using a damp
cloth. Please do not use any scouring agents, since they may
leave scratch marks on the surface.

The heater is intended for the fixed connection to a ceiling or
wall socket.
The device is connected to the AC mains system with a pow-
er cord connected and a connection socket on the installation
side.
NOTE
The connecting cable can be extended using a cable of the
SIHF-J3G1.5 mm² type. A direct connection to the device cannot
be implemented. The length of the connecting cable must be
between 1.0 and 1.9 m.
An all-pole disconnecting device with a minimum contact open-
ing width of 3 mm has to be mounted into the fixed electrical
installation in compliance with the installation regulations.
HEATING MODE
The heater is operated by means of direct connection via
switch, via an external room thermostat (eTOUCH eco), or
via a radio receiver (ET-111A) in connection with a radio-con-
trolled room thermostat (ET-14A). These items can be ordered
as accessories. Please observe the operating instructions
of the respective product.

ATTENTION
:
If the main cable to the device is dam-
aged, it must be replaced immediately by a spe-
cialist.
ATTENTION
:
When you want to clean the LAVA
®
infrared heating, the heating device must be cold!
