Calorstone technology advantages
Calorstone electric heating solutions are based on the matching of stone and carbon heating. This has an important feature: an electric conducibility with an intermediate value between synthetic fibers and metals. The carbon wire, if passed by electric current, shows a very high Joule effect, so a low voltage current is needed to generate heat. Beyond its veins uniqueness, the stone has a very high thermal capacity; this allows it to reach the set temperature ( approximately 70°C) and to keep it for a long time, irradiating heat to the environment even when turned off. As a consequence, lightings and shutdowns of a Calorstone panel during 24 hours are much lower than ones of similar panels, realized with other surfaces ( ceramic, aluminium, glass, metal).
Calorstone electric radiant panel heaters are realized in::
- Standard 300 watt
- Standard 600 watt
- Vertical 300 watt
- Vertical 600 watt
High performance
Carbon wire, together with thermal capacity of the stone, enhance caloric value of 50% minimum, compared with an electric system in copper. This basic feature of our product allows an effective yeld of 450 watts, with a consumption of 300 watt, and of 900 watts with a consumption of 600 watts.
Power
Our electric radiant heating panels are realized in two versions:
- 300 watts. (Yeld 450 watts).. Based exclusively on the principle of radiant heating through infrared rays.
- 600 watts. (Yeld 900 watts). Based on the principle of radiant heating through infrared rays, it can also use a further convectives 300 watts, to obtain desired temperature in a lower time.
Comfortable heat
Radiant heat doesn’t warm the air, but irradiated bodies and objects. These ones release to environment a homogeneous heat, enhancing comfort. With radiant panels, floors, ceilings and walls are at the same temperature, creating an extremely homogeneous and comfortable environment. In traditional heating systems, working through convection (radiators), the principle is the opposite: cold air on the floor gets warm and rise to the ceiling: this causes a continuous movement of air and dust, and a non homogeneous temperature in the room: to have 20°C at man height, we find 16°C on the floor and 22°C at the ceiling, while walls remain cold.
Clean energy
Calorstone radiant panels heating technology allows to heat with no polluting emission: no smoke and no carbon dioxide. If the house is equipped with a photovoltaic system, even energy production will be clean and emission free.
Thermal capacity
Thermal capacity of a material represents its attitude to accumulate heat, which is then released to the environment. The more the thermal capacity is high, the less the inside temperature change when outside temperature vary. It’s represented by specific heat, that is the quantity of heat needed by a material to enhance its temperature by 1°C.
Examples.
Average specific heat of solid bodies, expressed in kcal/ kg °C (1kcal = 4,186 joules).
- Steel 0,12
- Alluminium 0,21
- Sandstone 0,21
- Silver 0,056
- Asphalt 0,22
- Coal 0,20
- Cast Iron 0,13
- Wool 0,41
- Pine Wood 0,65
- Brick 0,18
- Stone 0,20/0,33
- Copper 0,09
- Sand 0,20
- Cork 0,49
- Land 0,18
The natural stones (specific heat from 0,20 to 0,33) remain the best thermal condensator (thermal flywheel) available on market, by a technical, ecological and economical point of view.
