If you are looking for economical and comfortable method for warming of your garage or warehouse, we can present you the best decision – infrared heat. Infrared garage heater units work on the major principle – they warm only people and objects. So if person comes up to the radiant heater, he will feel warm, and it does not matter what is going on around him. We can compare this method of heating with the sun energy. Our sun is really like the largest infrared heater in the world. Let’s imagine that the outside temperature is 20 C, and you are standing in the yard. The sky is clean and there are no clouds, the sun is shining brightly – so you will feel warm and 20 C is enough for it. But if the sky is grey and there is no sun, we will feel cool at the same temperature. We can make the conclusion that our temperature of body is changing, while the temperature of the air stays the same.
Principle Of Operation Process
The working principle of infrared radiant heating has been derived from the sun. Infrared waves, which come from the heater, go through the air almost without any losses. Waves turn into heat only at that time, when they touch objects and people. When surfaces become warm, they act like radiators which give off heat . A long flame, which is inside the infrared tube, is generated by a burner box and booster fan. This flame spans the length of the infrared tubes. When these tubes became warm, energy is radiated around the tube in all directions. Reflectors above the tube are used as collectors of energy and force it down to the floor.
Natural Gas Infrared Garage Heaters – Advantages:
- high efficiency – it is 1/2 more efficient than unit heaters, which work on gas;
- low noise – no big mover of air;
- cleanliness – no dust or dirt is circulated throughout your work space;
- comfort – your warmth is not affected by the surroundings.
Things You Should Know About Infrared Garage Heaters, Which Work On Natural Gas:
- you should maintain clearances;
- the first price is higher than most units;
- long tubes need a lot of ceiling space;
- single stage control vs. 2 stage control: the first one allows the unit to start working and to turn off. The second one is responsible for better matching with your heating needs by staging the burner from high level down to low, before the system is turned off. Such technology cuts your paying bills, and provides the highest level of environmental comfort.
- hanging and vent kits;
- alternative metals for atmospheres of corrosive type;
- most devices are single stage (on/off). Some of them offer 2 stage controls which allow the burner to operate on low, high or off. Such units provide better control of temperature and save your paying bills.
How To Install Natural Gas Infrared Garage Heater:
1) Firstly you should fasten tubes, burner box and reflectors according to the descriptions of the manufacturer.
2) Then you should suspend the tubes, burner box and reflectors with the use of chain and “S” hooks.
3) You have to install gas piping.
4) Then you should install vent pipe.
5) You have to wire 115 volt power to the burner box.
6) At the end you should wire a low voltage thermostat to the burner box.
Common Questions And Useful Answers:
1) Tell me more about infrared heating?
The sun is the ultimate source of radiated heat. It generates vast amount of infrared heat through gas consumption. This infrared heat goes directly through space, but it heats the surface of the earth and is, in fact, the reason for possibility of life on earth. For example, in winter, when the sun is shining brightly, it comforts us even if the weather is cold and frosty.
The second name of infrared heaters, which work on gas, is mini suns. They are called so because of their relation with gas consumption (natural gas or propane) to provide warmth. Infrared heat warms not the air, but only objects and people at occupancy level. This is a major benefit because heated air goes up to the ceiling where it is not needed, and needs a lot of money to pay for its heating.
2) What is the difference between infrared heating and conduction and convection heating?
Warmth can be passed in the following 3 ways:
- By conduction through solid bodies, such as through a windowpane in your home, which is heated, to the (cold) outside. The level of heat transferred by conduction is proportional to the difference of temperatures and the conductivity of the material through which the warmth passes.
- Through convection by warming air and moving the warmed air to a cooler space. For example, air is warmed as it passes over the elements of an electric baseboard heating unit; the warmed air goes up by convection and draws cooler air behind it to in turn be heated by the heating unit.
- Through radiant heat transfer, which unlike the other 2 ways does not need an intermediate conductor material or convector medium (air). The reason is an infrared energy. This energy, like light, comes directly from the source to the receiver. The level of heat transferred depends on the absorption of the receiver, the emissivity of the source, the difference between their absolute temperatures (raised to the fourth power), and the distance between them.
3) Can you describe the working process of infrared heaters?
Most infrared units use gas combustion (natural gas or propane) to warm a steel tube (tube heater) or ceramic surface (luminous –high intensity heater) which subsequently emits infrared heat. The amount of infrared heat, which is emitted, should be noted. Be aware that an infrared unit produces both infrared radiant heat (that is directed at people and objects) and convection warmth that rises and is for the most part lost.
4) Can we name infrared heating as safe method?
While the sun is a terrific manufacturer of infrared warmth, it also delivers damagingUV rays, which leads some persons to falsely conclude that the same problem applies to infrared units. The sun produces UV because it is a source of extremely high level of temperature; infrared units are a medium temperature source of energy – the ideal range for 3 positive facts: it is below the UV range, a greater amount of the heat energy is converted into infrared heat, most materials are highly receptive to medium wave infrared heat. The latter is a main answer on the following question: why infrared units can warm, cure and dry more economically and faster than competing systems.
5) How does infrared heating warm spaces in a garage?
Gas-fired infrared units are mounted overhead to direct infrared energy to the floor and the objects, including individuals, at the occupancy level of the garage. The infrared energy is absorbed by the floor and objects at floor level – all of which become warm, and in turn that all warms the air in the space. Moreover, the floor and objects continue to release heat to the air, even after cold air is introduced or the infrared heaters are turned off. Convection heating, in sharp contrast, has two major drawbacks: the total loss of heated air to ventilation air changes; hot air ‘stratification’ as it rises to the ceiling, where it is not effective in providing comfort to occupants.
6) Who controls the temperature in an infrared heating system?
A thermostat stops the infrared units at that moment, when the desired level of air temperature is reached.
7) What is better to choose: a tube heater and a luminous heater?
The key moments are the mounting height of the unit and the heating application. If the mounting height is 15-70 feet, or you need focused or (spot) heating, you should choose a luminous heater may be the best. You should better choose a tube heater if:
- the mounting height is 10-25 feet;
- a sealed combustion system is needed (direct venting and combustion air introduced directly to burner);
- the aim is to spread warmth over an area of low loss of heat.
8) Is there any difference between spot and space heating?
Space heating is the method of the warming of an entire area or whole house to avoid freezing or just for comfort. Spot heating is the method of the warming of a room within a much larger unheated structure, such as a shipper’s station in an unheated warehouse, the spectator stands in an ice arena, a restaurant patio, or work stations in a courier depot.
Area heating (spot) is a method, which provides comfort to a person or group of persons without heating the entire area or house to a comfortable level of air temperature. Luminous infrared heaters are the only units which offer an economical and practical answer to the question of providing needed level of comfort in relatively large unheated structures, which are sparsely populated. There are no more methods of heat transfer, which can warm persons without wasting heat to surrounding air.
The design indicator for the unit of infrared for spot heating differs from space heating. In a space heating unit, a combination of direct radiation and air temperature provides the needed comfort condition. During spot heating, only the direct radiation comes in to play in determining the comfort attained by the persons in the heated room.
To do a successful design of a spot or area heating system, the designer must examine and understand the design conditions in the place to be heated. The velocity of the air in the room must be determined carefully. The level of surrounding air temperature and the activity level of the persons in the room to be heated must also be fixed.
When needed conditions of the design are established, the proper model and size of the luminous heater can be chosen for effective heating of the area or individuals in question.
9) What are the major steps of a right installation?
If you want to feel all aspects of comfort, you should keep proper spacing down the length and width of the building. During the design works, you should also take into account warm up times, safety margins for zone heating and comfort levels. A mix of tube and luminous heaters is the best heating solution for many types of houses.
10) How do you cope with a problem of the dirty air?
Clean outside combustion air can be supplied by the direct ducting to a tube heater. A fresh air duct is attached, and direct venting goes outside, a tube heater is a sealed combustion system that can work in very dusty conditions. If your selection is the unit with ‘low level’ dust contamination, you can utilize luminous heaters, if you provide regular maintenance and cleaning.
When we are talking about any system of heating, the fact, which should be taken into account, is the properties of chemical contaminants. The viable decision is often a ‘sealed combustion’ tube heating system.
