HEATING
Do not power-on unit until it is installed.
Depending on the thermal insulation quality in your home,
the required heat output of the radiator will range from
3 to 20 W/ft² (30 to 200 W/m²). The LAVA® glass radiator
has a very high radiation fraction and a low proportion of
convective heat output. The surface temperature, for safety
reasons, is limited to appoximately 203ºF / 95 °C, thus
the overall performance of the device is limited. For this
reason, these devices are used as a sole heating solution
only in very well insulated houses.
ETHERMA LAVA® glass radiators warm predominantly
solid objects and only a small proportion of the air directly,
so these devices are ideal for supplementary heat. In order
to achieve the same feeling of comfort as with convection
heating, the indoor air temperature can be lowered by 2-3
°C/F. Each degree reduction can save about 6% in heating
costs, depending on the respective heating behavior and
thermal insulation in the room. The unit can be turned on
when a seldomly-used room is occupied, to provide a warm,
cozy feeling.
Fix mounted thermostats should be mounted next to the
heated room’s entry door at 4’ or 1.3m height from floors.
An alternate location is on an interior wall, not subject to
direct sunlight. The thermostat should not be installed
within 3 feet of the LAVA. Power the thermostat with a GFCI
Protected Circuit.
Depending on the size of the unit, the LAVA® glass radiator
will require some time to reach its operating temperature.
The glass sheet consists of 1/4” (6mm) toughened safety
glass (ESG). This glass is much more durable than
conventional glass, and is designed for significantly higher
impact forces. However, you should avoid excessive use. In
case of damage, ESG shatters into many small pieces with
blunt edges, to minimize the risk of injury.
Please note when choosing an installation location, that
a very small percentage of toughened glass products
can exhibit “spontaneous breakage”, i.e. when the glass
shatters. This can occur even when external influence isn’t
indicated. Choose the installation location of the device so
that there is no danger to people or nearby objects.
ATTENTION: Avoid any kind of load on the glass itself,
especially directly on the edges! Do not lean it against
anything, or lean anything against it!
Please refrain from placing any objects between the LAVA®
glass radiator and the persons to be heated. Objects
between the radiator and people will block the heat from
the people themselves.
MAINTENANCE AND CARE
The LAVA® glass radiator is designed to give its heat over
the glass surface in the form of far infrared radiation. There
are no moving parts located on the device that require
special maintenance. For care of your glass radiator, we
recommend commercial glass cleaner. Please do not use
abrasive cleaners, as these can cause scratches to the
glass as well as the painted surface. Clean the unit before
every heating season, at a minimium of once a year.
ATTENTION: Prior to cleaning, please ensure that the
LAVA® glass radiators are turned off at the circuit breaker
panel and that the unit is at room temperature!
SPARE PARTS
Please contact WarmlyYours for any replacement parts
required. Only use original spare parts.
