Thermostats
Thermostats provide basic heater control at little cost. You can
also use them as thermal cutoffs in conjunction with other
control systems. All thermostats come with a 1.5" (38.1 mm)
long, silicone rubber coated sleeve for electrical insulation
(case is electrically live), and mounting adhesive.
These thermostats are ordered separately. For information on
ordering heaters with factory installed thermostats contact

Pre-cut insulators
Trimmed to the same size as heaters, these pads provide
thermal insulation to minimize heat loss. You can also place
them between clamping plates and heaters for uniform
pressure. Optional pressure sensitive adhesive (PSA) backing
permits easy installation. It will not bond permanently and
may be removed later without damaging the heater.
* Every mica heater comes with two sheets of ceramic paper
free of charge. Order extra sheets here.
You can estimate heat loss with the following formula:
where:
W = Watts of heat lost through insulation
A = Heater area in square mm
