The device does this by turning heating and cooling devices on and off and regulating air flow of a heat transfer fluid as needed. This maintains the correct temperature. Thermostats may be used to control heating or cooling a system, or may be a component part of a heater or air conditioner.

Perlite is an amorphous glass mineral of volcanic origin. Typical analysis: 70-75% SiO2, 12-15% Al2O3, Na2O 3-4%, K2O 3-5%, Fe2O3 0,5-2%, MgO 0,2-0,7%, CaO 0,5-1,5% Loss On Ignition 3-5% Properties: When it reaches temperatures of 850"“900 Â°C, perlite softens (since it is a glass) and water trapped in the structure escapes and this causes the expansion of the material to 7"“15 times its original volume. The expanded material is a brilliant white, due to the reflectivity of the...
