Warranty
For heaters and control units in private use, the warranty is two (2) years. In commercial/professional
use, the warranty is three (3) months. Commercial use refers to facilities in which the heater is in
use on a continuous basis, such as fitness centres, swimming pools, housing companies etc. It is not
recommended that the heater is on for longer than six (6) hours at a time. Retain the sales receipt or
warranty card. The warranty does not cover external or internal mechanical damage caused by, for
example, the impacts of stones or the heater falling over. The warranty also does not cover defects
caused by acts of nature, such as lighting or damage caused by overvoltage. Please also see chapter
“Changing the heater stones”.
Removing or re-stacking of heater stones are not covered by the
warranty in a potential warranty maintenance.
Maintenance and spare parts
In case of a fault that cannot be solved, please contact the store where you purchased the heater or
email [email protected]. Spare parts can be purchased from Mondex distributors and the manufacturer.
When purchasing spare parts, please refer to the name, power, serial number and manufacturing date
of the heater to ensure you receive the correct parts.
Natural stone as material
Small pebbles or pieces may come off the natural stone used in the heater. As this is not a failure of
the organic material but a natural feature that cannot be predicted at the time of manufacturing the
product, the manufacturer is not responsible for any damage.
Changing the heater stones
Re-stack the heater stones and replace any eroded stones annually (every three months in
commercial/ professional use). The good condition and proper, spacious stacking of the stones around
the resistors inside the heater ensure a sufficient air flow between the resistors. If this is not carried
out annually, a proper air flow may be obstructed and the resistors may break prematurely, which is
not covered by the warranty.
