Radiant Heating Principle
Radiant heating is the heating of a surface by the absorption of rays emanating from another surface. The heating of the Earth by the Sun is the best example to this. Rays that travel for 150 million kilometers from the sun through space and the Earth’s atmosphere, hit the Earth’s crust and relese their energy. Different types of heaters that are designed using this principle are utilized very successfully in various applications that seem very difficult at first instance; such as spaces with high ceilings, large footprints, no thermal insulation, low air circulation or open architecture.
Radiant Tube Heater Working Principle
Radiant Tube Heaters are composed of 4 main elements; Burner (1), Radiant Tube (2), Reflector (3) and Fan (4). The gas that is combusted by the burner at one end is circulated inside the tube via the suction of the fan at the other end, and is discharged at the point of cooling. This way, the gas that travels the length of the tube releases its energy as heat to the tube. Outside surface temperature of the tube reaches 300oC. Radiation from the tube is directed downwards by the reflector placed on top. Rays that are directed without being effected by air streams are converted into heat as they hit objects (equipment, people, floor, etc.) and the heating process is commenced. The feeling of warmth under the sun on a sunny but cold winter day, or a similar feeling of temperature increase when moving from the shade to under the sun on a hot summer day are the best examples to the radiant heating principle.
Advantages of Radiant Systems
• 30-50% more cost efficient compared to Centralized Hot Air Ventilation systems.
• Maintenance costs are very low.
• Electricity consumption is near zero.
• Supply comfortable heating in a very short period.
• Easily assembled in a short amount of time.
• Run dust and noise-free without any air circulation.
• Can be applied on many different places and construction settings.
• Require little space, no furnace room or operators.
• Require no smokestack, is environment-friendly
• Initial cost is low
Furnace rooms are comprised of many different equipment with different operating efficiencies. Energy produced in the room is transferred to the desired space via piping.
This intrinsically causes losses in the whole system and a drop in efficiency. A disorder in any one equipment in the furnace room translates to a possible downtime in the whole system. On the other hand, only the specific device is down in the event of a fault with radiant heating, other devices in the system continue operation and the place does not cool.
