Radiant Panels

Radiant Panels – GENERAL ARGUMENTS

Under certain conditions between bodies with different temperatures heat exchanges occur. A body with a high temperature transfers from its heat to another body with a lower temperature. As the temperature passes from a warmer body to a colder one, the warm body’s temperature decreases, and the cold body’s temperature rises.

There is no heat exchange between bodies with the same temperature.

The phenomenon of the heat passing from one body to another is called heat transfer.

There are three types of heat transfer: by conduction, convection and radiation.

Heat transfer by thermal conduction is the phenomenon of heat transfer from a warm body to a colder one being in direct contact with each other.

Heating by convection represents a process in which heat passes through a fluid (air, water) and a solid warmed up body (an electrical resistor).

Infrared radiation has been discovered by the German physician, composer and astronomer William Herschel, in the year 1800. Herschel has discovered that when light passes through a glass prism is separated in a specter of colors. Measuring the temperature of each color he has observed that temperature rises from the blue color towards the red color, discovering at the same time that under color red appears a radiation with a much higher level of temperature. He named that thermal radiation infrared radiation, that is radiation under red (infra in Latin = under).

Herschel has discovered radiation in 1800, but it exists since forever and people felt its benefic qualities over the time. Radiation warms up both us and the surrounding bodies. In winter time on a sunny day we can sunbathe on the snow, although the surrounding temperature is far below zero, this delight is due to the infrared radiation emitted by the sun.

The first applications of infrared radiations heating were in the automotive industry at dye drying furnaces. The system of Radiant Panels heating copies on a reduced scale the action of infrared radiations emitted by the sun. Thermal waves achieved electromagnetically transmit directly thermal energy and without transport losses to all solid bodies from the radiation area. Inside the rooms the infrared radiations warm up both living and amorphous bodies, and also the walls of the rooms, the latter at their turn transfer temperature to the environment until a thermal balance is reached. Infrared radiations do not warm up the air within the room, because they have another frequency than the air molecules. As radiations warm us up directly, we will always feel a temperature higher by 2-3 Celsius degrees than the one of the environment, so in order to have a good thermal comfort, there is no need to heat up a room to a temperature as high as the one needed in case of heating by convection. It has been proved that in case of electric heating the rated power of converting electrical energy into heat by radiation is about 97%, and by convection about 70%.

Advantages of Radiant Panels heating

Infrared radiations emitted by Radiant Panels heat up directly the walls of the rooms, assuring this way a controlled humidity of the environment, which leads to the elimination of dampness and mold from the rooms with excessive humidity.

Infrared heating does not create air currents to generate dust movement, which would cause problems to people with asthma or other respiratory deficiencies.

The effect of direct heating on people leads to a better blood circulation that generates in-depth heating of the body, and not a limited heating on the surface as in the case of heating by convection.

The radiant panel system is cheaper as primary investment than the other types of heating, eliminating the installation costs of a boiler that uses a conventional source of energy.

The radiant panel system eliminates the costs and shortcomings created by the installation of radiators, of hot water supply networks of radiators, or the building of a chimney, where appropriate.
Radiant panel heating is a totally ecological system, as there are no pollutant residues of any nature occurring.

Radiant Panels may be set up on side walls, on the ceiling, or by means of auxiliary mounting supports they may be set up on the floor or on different bodies which allow us heating that area (offices, chairs, tables, …). They may be used is wet environments, bathrooms or pools, assuring this way humidity control.

There is no need of special approvals to put it into operation.

A high reliability is assured as there are no parts in movement.
The set up is very simple: two screws for fastening on the wall the mounting supports that the panel is equipped with and then they may be connected to the mains and started. The panels may be installed both vertically and horizontally.

For a better management of electricity costs, the Radiant Panels are connected to the mains by means of an ambient thermostat.

Simple maintenance: it should be cleaned once a month with a dry soft cloth after it has been disconnected from the mains.

Prisma Info Company produces three types of Radiant Panels:

1. SMART Radiant Panels – with special destination for domestic environment
2. Protector industrial Radiant Panels – intended for heating big size rooms: industrial halls, agricultural halls, productions workshops, car washes, churches, cinemas, …
3. Radiant Panels with quart tubes – intended for heating terraces, kiosks, balconies, bathrooms

SMART Radiant Panels

Smart Radiant Panels are completely manufactured by Prisma Company, functioning in long wavelength range of infrared radiations at a temperature on surface of 120 degrees Celsius, which confers them a better emission of infrared radiations, than of the imported ones that function at 80 degrees temperature.

Smart Radiant Panels are manufactured in 7 typo-sizes:
