convection currents are not created. This means that dust is not circulated and drafts are not created. This
brings higher levels of comfort, not only to allergy sufferers but to everyone in the room.
The THERMOFILM™ heating system is completely invisible and unobtrusive and allows more flexibility in
creating the perfect living environment. It is reliable, safe and manufactured to last. Being electric with no
moving parts it is completely maintenance free.
OPERATING
Operation of your THERMOFILM heating system is similar to other conventional heating systems. Your
method of control is via the wall mounted room thermostat. Set the thermostat to your desired
temperature and the system will warm the room. There are several points to consider when operating
your system to ensure economical operation:
1) Following installation of your THERMOFILM heating system there are several precautions you should
take on initial start – up of the heating system. Do not be tempted to turn the system immediately after
laying the finished floor. Depending on the floor covering please allow sufficient time for the wood to
acclimate (see manufacturer’s guidelines). Bring the system up to temperature gradually in stages over the
next few days using the floor limit sensor temperature setting.
2) Each room installed with a THERMOFILM heating system shall have its own thermostat. This means that
you can individually set the room temperature based on the use of the room. If the room is rarely used,
turn the thermostat down to a lower level to conserve energy.
3) Your THERMOFILM heating system is a direct acting system. However, depending on the subfloor and
the floor covering installed, there may be a certain amount of thermal lag in the system (heat-up and cool
down periods). Please anticipate these when switching your system on and off. Careful time clock control
of on/off periods ensures maximum comfort at minimum cost.
4) Although your radiant heating system is less affected by air change/ventilation losses than a traditional
convection heating system, it is good practice to minimize drafts from open doors or windows as these can
make occupants feel cold.
5) Set the thermostat to your desired comfort level and leave it. Setting the thermostat to at high
temperature will not make the room get to temperature quicker. It will merely overheat the occupants
once the set temperature is reached.
6) Thermostats are fitted with floor limit sensors. The temperature of the actual floor can be varied to suit
different applications and tastes. We recommend a maximum floor temperature setting of 82°F for
optimum comfort conditions.
Be Aware
Although your THERMOFILM heating system requires no annual maintenance, care should be taken to
ensure that the system is not damaged. Additional information for renovating and repairing is available in
the system’s Installation Manual.
1) Never pierce the floor. Piercing an electrically conductive element with a nail or screw can trip the GFCI
and cut all power to the system.
2) Never cover any heated part of the floor with solid bottomed or permanent floor fixtures or furniture.
This could trap heat and potentially cause local overheating.
