Types of Infrared Heating
Types of Infrared Heaters
HIGH INTENSITY AND LOW INTENSITY INFRARED
Detroit Radiant Products Company offers a full line of both high intensity and low intensity units that require little to no maintenance. Re-Verber-Ray® infrared heating products are efficient, cost effective, and satisfy the heating requirements for a wide variety of indoor and outdoor applications. We are proud to be the first manufacturer to offer a product that applies the theory of truly efficient two stage heating to infrared.
High Intensity Infrared Luminous Heaters
Gas-fired high intensity heaters are direct-fired and pass a gas-air mixture through a porous matrix refractory material which ignites evenly across the surface.
This surface is heated to temperatures of 1350°F or above, emitting a large concentration of infrared radiation that may be directed anywhere heat is desired. High intensity heaters typically operate unvented. Proper ventilation is necessary to dissipate combustion gases released into the space.

Infrared Space Heaters
Infrared space heaters are best applied in buildings with high ceilings and areas where there is a high demand for a heat load, such as loading docks or bay areas.
-
Infrared Patio Heaters
Patio heaters are used to provide outdoor spot heating to applications such as restaurant patios, decks, and vestibules.
-
Portable Construction Infrared Heaters
Portable heaters are generally mounted to a 20-lb., 10-inch base propane tank and are designed for areas under construction. They are ideal when temporary heat is required or where a permanent energy source is not available.
-
Electric Infrared Heaters
Electric infrared heaters produce heat by running an electric current through a high-resistance element. They are commonly used in areas where gas is impractical or unavailable.
Low Intensity Infrared Radiant Tube Heaters
Gas-fired infrared heaters are an indirectly fired appliance, and have a radiating surface between the combustion and the intended load.
When there is a call for heat, a flame is ignited within an exchanger. The exchanger is then heated to temperatures up to 1350°F, emitting infrared energy. This energy is directed to the floor level via reflectors and is absorbed by people and objects in its path. A heat differential exists along the length of the heat exchanger because more heat is produced in the first half of the tube at the burner/combustion end, than the second half of the tube at the exhaust end. A well designed unit minimizes this temperature differential.
-
Forced Draft Systems (Push)
A forced draft system operates under a positive pressure, pushing the products of combustion through the length of the exchanger tubes. This type of infrared heater is easy to service and install because all of the components are housed in one compartment. When compared to other tube heater types, push tube heaters offer a variety of production, installation, and operating benefits.
-
Draft Induced Systems (Pull)
A draft induced tube heater operates under negative pressure pulling the products of combustion through the length of the exchanger tubes. This type of infrared heater offers reliable performance in high-wind applications and sometimes can allow for extended vent runs.
-
Multiple Burner Vacuum System
Multiple burner systems operate under negative pressure pulling the products of combustion through various runs of radiant exchanger tubing via a powerful vacuum exhauster pump. This type of infrared heater is used when minimal building penetrations are required, or if extended vent runs are necessary.
