What is Radiant Heating?

Radiant heating is a cost-effective, reliable method of heating indoor and outdoor areas that require a more even spread of heat. The best way to simply describe how infrared gas fired radiant heaters work is to liken it to the most reliable known heater – the Sun. The heat energy from the Sun radiates through space and our atmosphere, striking the Earth’s surface and heating it. It is this warmed surface that then heats the air and raises the air temperature. For this reason, radiant heating is a popular choice when considering building with high extraction rates and garden centres / greenhouses with high heat loss due to the high amount of glazing. Due to the versatility of radiant heaters, they are also widely used for factory and warehouse heating along with spot heating applications.

Why Radiant Heaters?

Radiant heating, unlike warm air heating, doesn’t heat the air. It first heats the people and the objects around it, including the floor, which in turn act as secondary heaters, raising the air temperature. The main benefit of radiant heating is the reduced loss of heated air in areas with open doors and windows.

Unlike warm air heaters which must use excessive energy to heat the building’s atmosphere once a door has been opened, objects heated by radiant heating will continue to stay warm. For industrial and commercial buildings such as distribution centres or warehouses that often have large doors open to cater for deliveries, radiant heating is the most cost-effective solution for maintaining suitable working temperatures.
