Low intensity radiant heaters, such as a tube heater, run emitter temperatures of between 600-1100F (315-590C), and emit no visible light when running. Radiant heaters are divided into two categories based on how hot the radiant emitter (heat exchanger) gets. What types of Radiant heaters are there, and what are the differences? Remember – radiant heaters are most commonly controlled by thermostats, and thermostats measure air temperature, not the temperature of the objects in a room! When the mass in a building (floors, walls, objects) are warmed after absorbing the infrared energy directly, a portion of that heat energy is transmitted into the air via the process of convection. While it is true that air is not used as the medium to transmit the heat, the air is indeed heated when radiant heaters are used. The answer is that radiant heaters do both! It is a common misconception that radiant heaters do not heat the air in a building. You are able achieve your required temperatures with fewer BTU’s, while using less fuel, and while ensuring that your fuel dollars are spent where they are needed most – heating the people, air, and objects within the room.ĭo radiant heaters heat the objects in a space, or the air? Radiant tube heating allows you to directly heat your target areas. As the air becomes hotter, it rises to the ceiling, heating hundreds of cubic feet of unused space before heating the floor, surfaces, and people within the space. Other methods of heating rely on raising the temperature of large volumes of air in order to raise the ambient temperature of the room. – Steel hangers with suspension points for both flat and angle mounting of reflectors.įull installation/operation instructions for the Heatwave radiant tube heater (PDF 4.5 MB) – Highly polished material for increased reflectivity. – Highly efficient, wide angled aluminum reflectors – engineered to reflect maximum radiant energy over the largest effective area possible. – Emitter tubes provided with a 20 year burnout guarantee. – Swedged tube for ease of installation – no couplers or clamps required at joints. – Secondary tubes constructed of 16 gauge carbon steel for high emissivity. – Primary combustion tube made of high temperature, high emissivity specialty alloy. – Emitter tubes are 3″ diameter, 16 gauge North American steel. – Factory ready to accept either 24V or 120V controls. – Flame observation port to visually observe combustion. – Dual air proving switches monitor combustion air and exhaust airflow for safety. Blower motor is externally mounted for ease of accessibility and to simplify intake – air connection (4″ combustion air intake duct adapter comes standard). – Totally enclosed blower motor with internal thermal overload protection. – Continuous combustion monitoring with three to five ignition trials before 100% safety lockout. – Built with 100% North American made electronic controls. – Reliable electronic hot surface ignition. – Natural gas (model GH40N) and propane (model GH40P) fired models built to order with no field conversions required. Perfect for garages and workshops, the Heatwave can also be used anywhere that space constraints make other heating equipment difficult or impossible to use. At 40,000 BTUH, 8′ in length, and only 8 3/4″ from bottom to top, the Heatwave can fit in smaller shops easily, and can be installed in building with ceilings as low as 8′.
