Radient Heating
Radient heating is an awesome way to heat regardless of what it might be that you are wishing to heat, your house, garage, patio, etc. Radiant heaters use the same means of heating as does the sun. A Radiant heater does not have as much capacity for heating as a gas or other type of heater, rather it may make a person 5 to 10 degrees warmer similar to when that person is receiving heat rays from the sun. When you are receiving heat from the sun, if a cloud blocks the sun's rays, a person or in other words you, will feel instantly cooler because you are no longer receiving the sun's direct infrared radiant heat rays. The passing cloud did not cool the surrounding air; the loss of warmth is due to the cloud blocking the transmission of heat rays from the sun, and not to a change in air temperature. Radiant heaters work in the same way. So, let's take a look at this and how it is beneficial to you.
Radient heating is great in that you do not have to heat your whole house, rather you just heat the people in your house. The radient heating emitter sends out heat rays in various directions. The speed of the heat rays is 186,000 miles per second. These rays do not heat the air directly, rather the infrared heat rays strike an object such as a person, a building, a table, or the ground and are absorbed by that object, increasing its temperature. The air around that person in turn will heat. The increased temperature of the object will heat air in contact with the object by convection, or in other words, by the intimate contact of a thin layer of air to the heated object.
Radient heaters are not all created equal, and some are more efficient than others. What you want is one where the geometry of the heater produces a radiant heat pattern that is efficient whether close or at some distance from the heat source. Some radient heaters are designed to allow different heat rays to reach different distances. For example, if a person is located twice as far from the radiant emitter as another person, they would receive only 25% of the radiant heat intensity; thus many radient heating has been designed in such a way that the person located closer to the heat emitter receives only 25% of the more intense heat rays while the person twice as far away receives 100% of the less intense heat rays. Thus, both people are heated equally, and neither are overheated due to excess infrared heat radiation. You want to look for a radient heating emitter that spreads the even infrared heat radiation over as wide a area as possible to maintain the body warmth of several people in any given area, not just one or two people.
Radient heating is a perfect option for heating your outdoor spaces as by using a readient heater you are not trying to warm up the whole outdoors, rather just the people in it. Outdoor radiant heaters work by heating people and objects directly, and not the air, which is good because the amount or volume of the air is enormous compared to what you heat when you use your gas or electric heater inside your home to heat the air that is contained within your walls.
Radient heating is a relatively new form of heating for use in homes, but is swiftly gaining popularity as it can be very cost effective and beneficial. If you are considering radient heating be sure to look into different emitters and find ones designed to heat people equally no matter their distance from the radient heat source.
