Radiant heating is the form of warmth most comfortable to humans, whether from the sun, a burning fireside or today’s energy efficient, discrete heating systems.

With radiant heating appliances we employ the radiant principle to directly heat objects, surfaces and people rather than having to warm the air first. This prevents wasteful heat stratification associated with convection of warm air, typical of traditional heating systems. Many people expect heat to rise, but in fact it’s only warm air that rises because warm air is lighter than cold air. Warming the air creates a convection current with hot air rising to the top of the room. The rising warm air is replaced by cold air and this creates a convection flow. With convection heating, such as traditional wall mounted radiators, much of the heat is lost to the unoccupied upper space of a room. In fact,the air temperature may increase as much as 3°C for each vertical metre in a room. ILO Design Radiant Heating appliances emit up to 75% of their heat output in the form of radiated heat. Thus, convection is reduced and most of the heat is then radiated

directly to the occupants.

Using radiant heating reduces heat stratification and provides comfort at lower room temperatures, thereby saving significant amounts of energy. In fact, a radiant heating system may easily use 50% less energy than electric baseboards. 


ILO Design Radiant Heating is available in a variety of types to suit anyapplication: all heaters include at their heart ILO thin film heating elements, which allows slim design with fast, reliable efficient heating and maximise the radiant heat output.
