Underfloor Radiant Heating

Underfloor Radiant Heating

What is radiant heating?

Radiant heating is the transfer of heat energy using energy waves. Heat energy in the form of radiant will always travel from a hot surface to a cooler surface. Consider the Sun, the Earth's only source of heat, which is 150 million km away. The Sun warms the Earth from a fantastic distance purely by using radiant energy. Even before the air is warm, heat from the sun can be felt, such on a clear winter morning, or on top of a snowy mountain. Warmth from the sun is instantaneous - you experience this when the sun emerges from behind a cloud.

So perhaps it's no surprise that 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.

What type of system?

There are three principle ways to install a radiant heated floor.

Heated cables or mats may be set in the concrete structural sub-floor or under tiles. For wooden and laminate floating floors a very thin yet technically advanced heat emitting film is used. Please refer to individual product data sheets for full specification and design information.

STRUCTURAL CONCRETE FLOORS

The heating cable is incorporated into the floor at the time of construction. Cable in rolls or presized mats is set into wet concrete, secured in place with plastic pegs and then covered by a level surface of concrete. When the slab is dry, the floor is completed. As with all floor heating, it is important that there is a layer of insulation below the cable to prevent heat loss from the back surface. After drying out and decorating, the heating system is ready to run. In this way, the whole floor surface, except areas to be covered by fixed furniture, will be turned into a large and gentle radiant heating source, ensuring even gentle and invisible heating for the room.

DECORATIVE FLOOR TILES

Radiant heating cable in the form of a pre-sized mat is placed on top of the concrete sub floor and tile cement is applied. Tiles are then placed over the mats. As with all floor heating, it is important that there is a layer of insulation below the cable to prevent heat loss from the back surface. After drying out and decorating, the heating system is ready to run. In this way, the whole floor surface, except areas to be covered by fixed furniture, will be turned into a large and gentle radiant heating source, ensuring even gentle and invisible heating for the room.

WOOD OR LAMINATE FLOATING FLOORS

Radiant floor heating film is supplied in rolls of a variety of lengths. The heating film is placed directly on top of the standard underlay, secured in place using suitable fixings, and then the floor surface is laid. This is an ideal solution for spot heating or retrofit applications.

Maximum Energy Saving

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 25% less energy than a traditional system when all savings are added up.

The principle of our underfloor heating is based on this experience. A large surface, the floor, is heated to a relatively low temperature (25-35ºC), the floor emits a sort of natural infra red heat, very near to the human body's heat.

An even temperature all around the room:

The heated surface is almost all the floor surface, thus the comfort of your heating system will be felt all around the room, without variation…

Cheaper than conventional comfort, for various reasons:

  • 90% of the electricity you consume will be transformed into useful heat.
  • No servicing and maintenance.
  • Each room heated independently at the proper level with precise control.

The even temperature gives you better comfort, no need to overheat one side of the room to have the other side.

  • Studies have shows that it is possible to achieve comfort with ILO TECHNOLO
  • GY heating film, at an air temperature of around 17ºC instead of 20ºC in usual heating systems.
