Whether you have a warehouse, dock, or workshop to keep heated, Invizatherm™ is the smart choice.  Let the quartz era end and a revolution begin with a zero maintenance heater.  You’ll never worry about bulbs to replace or reflectors to clean.

With no moving parts to wear out, Invizatherm™ will last you for years to come, all the while giving you safe, clean, energy-efficient heat.  There are no combustion products discharged, no flames, and no noxious gases emitted.  Meaning there is no need to ventilate.

To top it off, Invizatherm™ provides the most energy efficient heater in the comfort heat market, converting 95% of the used energy into useful heat.

Ideal Comfort Heat
The infrared or IR waveband is often subdivided into three regions: IR-A (.7 – 1.4 μm), IR-B (1.4 – 3 μm), and IR-C (3 – 1000μm). IR causes a heating effect when it strikes a surface, in the case of comfort heating this is normally the skin. However, not all IR is converted to heat.  IR can be absorbed or reflected.*¹ In the comfort heating world, we want to fall into the absorption range as much as possible. Good absorption directly correlates to better comfort heat. Generally, the longer the IR wave, the more absorption will occur (IR-C) and the shorter the wave, the more IR is reflected off of the skin (IR-A & IR-B).

Indeeco heating elements fall right in the sweet spot of the IR waveband, IR-C. Nearly 100% of the waves that the Invizatherm™ emits will be absorbed rather than reflected. Our competitors heating methods often land in the short-medium (IR-A and IRA B), which are ineffective for comfort heating applications. We’re translating every penny you spend on energy into comfort heat rather than reflecting it around the room.

How to determine the number of heaters required

You will need to find the approximate square footage of the area you wish to heat.

Now that you know how large your space is, use the below watts per square foot chart and reference the desired temperature rise.  This will help determine the kW that is required to heat your space.

After determining the total kW needed for your space. Visit the product portion of our catalog to select appropriately sized heaters for your space; keeping in mind voltage, phase, and wattage suitable for your needs. When determining the heater model and quantity that you need for your space, note that both Invizatherm™ and Invizatherm™ Thin can be ceiling or wall mounted. To achieve even heat distribution, we recommend smaller, more evenly spaced heaters throughout your space.


All Invizatherm™ and Invizatherm™ Thin heater models are capable of being regulated or “cycled” to control their heat output. Different methods of control offer difference levels of efficiency so each application should be examined to determine which control method is most suitable.

Invizatherm™ and Invizatherm™ Thin heaters do not come with built in controls. The heaters may be installed and operated without controls, in which case a heater is either 100% on, or it is 100% off. This may be acceptable in many applications; however, when controls are needed to regulate temperature or follow a heating schedule, Indeeco offers a variety of manufacturer recommended control options which range from single unit control, all the way to full system commercial and industrial grade control panels. See our catalog for additional control information.
