because 5 rupee is less than 10 rupee
In convection heat you heat the air first and then use the hot air to heat yourself. In radiant heat, the energy must be radiated directly from the heat element to your body. Note that radiant is much more directional.
Radiant heaters supply heat directly to the ceiling, floor or walls of a home. They use radiant heat transfer, which is heat moving directly from the hot surface to the objects or people in the room. This is the same effect as when you can feel the heat of stove burner from across the room. This type of heating is more energy efficient than forced-air heat because no heat is lost in the duct work. Since there is no moving air, it is better for people with allergies.
If you are asking do certain colours absorb or reflect heat more then the answer is yes. Black absorbs heat at a far greater rate than white. White is used to reflect heat.
White and light colors reflect heat. Black & dark colors absorb heat.
dark colours attract more heat than the light ones, the light colours reflect heat mainly
white marble
In my opinion, radiant heat is better than a traditional furnace. You have more control over how much heat you want, and where you want the heat. Using radiant heat is also more cost effective.

radiant heat
it depends of your house. if it has more than one floor then it might not. it also depends on how many rooms has radiant floor
It is shiny which allows reflection of heat more easily
Dark rocks will absorb more radiant heat than light rocks, for the same reason that any dark object absorbs more heat than an equivalent light object. Light objects appear "light" to us because they reflect more light than objects which appear dark. Dark objects appear dark because they absorb more light and reflect less. However, dark objects will radiate more heat that light objects. Actually, dark rocks do NOT absorb more radiant heat than light rocks. Nor do they radiate more heat than light rocks. Dark rocks DO absorb more LIGHT than light rocks and they then radiate this light at heat. Light rocks reflect the light rather than absorb it and therefore do not radiate as much heat. If you put a light rock and a dark rock next to a HEAT source, the amount of heat absorbed will be related to the makeup of the material rather than to the color.

A U.S. Department of Energy sponsored study concluded that radiant heat panels were 52% less expensive to operate than electric baseboard heat and 33% more cost effective air to air heat pumps.

Radiant heat is an excellent way to save energy. The heating system lays beneath your floor and the heat radiates up. It is more energy efficient in that there is more area radiating heat than other heating otions and thus quicker heat returns. This causes your heating system to run less and save you money and energy.
It is 21 times more effective than carbon dioxide in blocking escaping radiant heat.
