Thank you for choosing RADtec heating products.
This product operates in compliance with the information laid out in this manual.
***Attention! Before using this product, please read the manual carefully***
You have purchased the following model: RADtec Torrid Series - Infrared Radiant Heater
RADtec T4000/8r
RADtec T4000/12r
This model heater operates by projecting a “Radiant Footprint” over your living space. Radiant energy is transferred to peopl e
and objects within this projected footprint via radiant energy – similar to how the sun warms you up when you stand in sunlight.
This method of heating is very popular today because infrared heat energy transfer is hyper efficient. Remember, warm or hot
air is less dense than surrounding colder air and rises due to thermal convection. Infrared heat is not lost to air currents because
infrared heaters do not heat the air. Infrared energy does not “excite” air molecules, instead bypassing them and warming
whatever surface this energy hits thereafter.
Please reference the graphic below to better understand how this footprint projects from the heater you have purchased.
Description of RADtec Torrid Series Heaters:
RADtec infrared heaters are designed for various applications, both outdoors and indoors.
Example: terraces, patios, verandas, gazebos, hangars, workshops, etc.
RADtec Torrid series heaters have a stylish compact design. Applications can include both vertical(wall) and horizontal(ceiling)
installations. It is also possible to place this heater on a mobile stand (not included, purchased separately).
RADtec state-of-the-art infrared heaters use high efficiency heating elements. 95% or more of the electrical power consumed is
converted into a heat flux. Infrared heating achieves this efficiency by heating objects in the area without having to heat the
surrounding air.
What Does Heat Flux Mean?
Heat flux is thermal energy transferred from one substance to another per unit time and area denoted by temperature change
measured in watts per feet/meter squared units. In simple terms, it is the heat transferred per unit area. To obtain this value, one
must obtain the change in temperature, the thermal conductivity of the medium of conduction and the direction of the heat
transfer. Accurate figures are obtained when the system is in a steady state condition.
