Electric industrial heating – why it’s better than gas

Electric heating isn’t just for keeping us warm at outdoor soirées—it’s used in industry, too. In this post we explain some industrial applications for electric heating and why it is better than gas.

For industry

At Kelray, we’ve been supplying electric radiant heaters for industrial applications since 1992.  And our customers include Tiwai Point Aluminium Smelter, Gillies Foundry and Alloy Yachts.

But, what are electric heaters used for in industry? Here are some examples:

  • drying paint at panel beaters & boat yards
  • drying & curing fibreglass
  • removing moisture from timber.

Electric heaters are particularly effective in drying ovens and conveyor systems. The set-up costs are less than gas heaters, and they are more efficient to run. Electric heaters are also easy to retrofit: engineers design their own drying ovens and conveyors and order heaters and controllers to fit.

For people in industry

During winter, many warehouse and factory workers do it tough and put up with the cold. Their employers seem oblivious to the benefits of electric radiant heating.  However, they are ideal for areas like welding bays, despatch areas, entrance ways and workstations.

So, why is electric radiant heating better?

Gas heaters are not very efficient. You see, they work by way of convection. This means that air is heated when it makes contact with a hot surface. Then, the warm air is distributed into the area that needs heating. The problem, though, is the warm air spreads beyond the area it is meant to heat. And, if the gas heater is positioned near a door, outside air can blow the warm air away.

Electric radiant heaters don’t heat air. Instead, they direct infrared heat towards an exact location. The heat passes through and is absorbed by people and objects and then radiates outwards, warming those nearby. Only the required area gets heated.  As a result, electric radiant heating heats more efficiently and costs less to run.
