HOW IT WORKS ?

EFFICIENT

RADIANT HEATING

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 – this is a real problem in rooms with high ceilings or pitched roofs. In fact, the air temperature may increase as much as 3°C for each vertical metre in a room. And of course, if warm air is lost through
opening windows or doors, more energy is required to reheat incoming cool air.
However, 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.

COMFORTABLE

RADIANT HEATING

It’s true – people feel more comfortable with radiant heating – it is after all our natural heat source and because we can directly absorb the heat energy we actually feel comfortable at lower air temperatures in a room with radiant heating. This has been established by experience, test studies and is recognised in the European Standard for design of heating systems which allows the designer to calculate with lower operative temperatures safe in the knowledge that equivalent comfort will be maintained.

Radiant heating responds instantly to demand. There is no need to preheat a room. Simply switch on and you feel the warmth immediately.

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 design of all our Radiant Heating is based on this experience. The whole heating surface is heated to an even temperature and emits a natural sort of infra red heat very close to the human body’s heat.

… An even temperature all around the room:
The slim design and heating surface minimizes convection and maximizes efficient radiant heating.

… Cheaper than conventional comfort, for various reasons:
– Up to 75% of the energy used is converted in radiant rather than inefficient convected heat.
– No servicing or maintenance.
– Each room heated independently at the proper level with precise control.
– Possible to precisely match installed power to heating demand, creating the must efficient installation.
– The even surface temperature gives you better comfort.
– Studies have shown that with radiant heaters, it is possible to achieve comfort with air temperatures approximately 3°C lower than with conventional systems, meaning significant energy savings.

A REAL

COMFORT IN YOUR HOUSE!

The MASSACHUSETTS INSTITUTE OF TECHNOLOGY (MIT), in a purpose designed room experimented to determine the factors influencing comfort temperature.
Briefly explained, we can say that two tests were made:
– In the first phase, the walls are cold and the air is hot (up to 48°C!): the occupant feels cold.
– In the second phase, the walls are heated and the air is cold (10°C): the occupant feels warm.

Thus, it was determined that the temperature of the surrounding objects (radiation) is at least as important as the temperature of the air.
In the same way, you can feel the sun’s warmth in cold air. Air temperature is low, but radiant heat contribution is high.
The important factor is the exchange of energy on your skin which determines comfort. It is influenced by two factors : the temperature of the surrounding air and the level of radiation. The experience of the MIT shows that infra red RADIATION is a very important factor.
If there is significant air movement in the surrounding air, the skin surface will be cooled. This problem is avoided with Radiant Heating.
