A Brief Introduction to Infrared Heating Methods
An infrared oven is a device that uses thermal radiation to heat objects that then radiate back and keep the environment warm.
The first microwave ovens didn’t work too well and required the user to stand over the open flame to roast their foods.
It was later found that the infrared waves were able to penetrate and get to the center of the black stove so that the food could be cooked without having to stand in the direct flame.
Later, infrared heating devices were developed to use the same principle and to be more efficient.
Infrared is very much different from traditional forms of cooking as it doesn’t use any flames or burning oil.
The main ingredient for infrared heats is infrared radiation which is a light wave that is created by objects which are normally in darkness.
When the object becomes heated, then the infrared waves hit the surface and travel through.
These waves can then travel back into the room and come back to a heat source which causes the temperature to increase.
Unlike other forms of cooking, such as frying pans and grills which cause intense temperatures on contact, infrared cooking can heat objects without a single mark on the surface.
Infrared is also very safe to use and does not affect food quality in any way.
If you have ever wished that you could prepare a pizza or Chinese stir fry at home and avoid the cost and mess associated with deep fat frying, then now you can with an infrared hot plate.
There are many models and types of infrared heated dishes available, so it is easy to find one that suits your needs perfectly.
Many people prefer them because they can cook several dishes at once and because they can keep foods hot for longer periods of time.
They are also a very convenient option if you need to have your food heated quickly.
Infrared Heating – An Overview
Infrared heating has been favoured for millennia because like the warmth of the sun, it is entirely natural.
The infrared energy absorbed by objects which are subjected to infra red light passes straight through the object without being affected in any way by the electrons present.
An individual living in a hot area such as the sun can remain comfortable without concern for being roasted alive, whereas individuals who live in areas where the sun’s heat is below the level of comfort can experience discomfort.
Infrared heating can also be used on people who have respiratory problems such as asthma or on people with lung conditions and is therefore ideal for people such as smokers and people with existing respiratory conditions.
This means that objects which have been traditionally frozen or submerged in water will begin to warm up as a result of the heat generated.
The heat is produced by a small pump located at the base of the radiator, and this means that the entire system can be turned off and on quickly and easily, as per the need.
Another great benefit of using infrared technology is that the heat generated is completely clean, meaning that there are no harmful emissions created by the radiator.
As such, the radiator is completely green, and it means that people will not be left feeling greasy after using their new technology.
The future will bring new developments in infrared heating technology.
For instance, researchers have already begun experiments with using heat to help treat diseases such as Parkinson’s. Heat generated by infrared heating systems has also been developed to help combat skin conditions such as eczema.
As well as the research and development being carried out into creating more efficient systems, more companies are starting to invest in the technology, meaning that we could soon see many innovative products on the market which make use of the benefits offered by infrared heating technology.
For instance, if you have a lot of jewellery which is collecting dust in your box, you could buy an inexpensive infrared heating system to help bring it back to its former condition.
Longwave Or Far Infrared Water Heater
So, now we know what the Far Infrared Wave is we also need to know how it works. The longwave or the far infrared radiation is used to excite water molecules which then change their vibration state into heat.
The Far Infrared Wave has the properties that it can only travel in only one direction for as long as its transmitter stays in that fixed spot on the earth. If that transmitter changes its position then the Far Infrared Wave will have to travel over a longer period of time to emit the same amount of heat to the same place.
It is because of these properties that saunas use longwave water heaters to produce steam and infrared heat energy to warm their guests and give them relief from stress and tension.
The same principles are at work with saunas but unlike our home saunas they do not use electricity or steam to create heat but instead use longwave radiation to produce heat, which means they require little maintenance and cost little to operate.
These longwave water heaters do not however have the ability to heat large pools of water and so they are often seen being used in public gyms where large numbers of people are being cooled off at once. This is also where they are most commonly found in saunas.
Another place where you will see the two types of infrared heaters is in hospitals where doctors use them to treat patients with severe burns or cancerous conditions.
The infrared wave that these longwave radios send out are not visible to the human eye, they are however highly energetic waves which travel at the speed of light. This means they can easily kill cancer cells by emitting high levels of infrared energy directly into their bodies thus giving them painless treatments that are often far more effective than pain killers prescribed by doctors.
Middlewave Is Better Absorbed by Skin and Less Rejected Than Shortwave
When it comes to comfort heating, a recent discovery is that the temperature of air can be altered by the thickness of the air layer and the direction that the wind blows.
Researchers have discovered that the difference in absorption and reflection is caused by the “pressure” or “viscocality” of the air. The higher the pressure, the less absorbed the radiant heat energy from the sun. The direction of the wind also has an effect on how the absorbed and reflected radiant heat energy is distributed. A high-pressure air stream causes more heat energy to be absorbed than a low-pressure stream.
In order for a comfort heating system to work properly, the correct combination of a high-power heater and a properly sized and exposed panel surface is necessary.
A properly sized panel surface is one that is no less than 0.5 inches thick.
The reason for the recommendation of a specific thickness of the panel surface is because the smaller the space within the panel, the less reflective and heat-absorbing the surface area of the unit will have.
If the space between the panels is too large, the heat energy will not be spread evenly throughout the structure.
Can Comfort Heat Lamps Emit Shortwave?
Comfort heaters are a unique breed of portable heating devices that have no blower in the device but rather emit warm air from an air tight lamp that sits upon a metal stand.
These lamps can be used to provide any area with warmth during the night, as they do not create a room temperature with the heat they emit, but rather ensure that the room is comfortable enough to sleep in.
These lamps are not suitable for all circumstances.
One of the main issues is their inability to regulate the temperature of a room; heat which is constantly shifting and fluctuating can quickly cause discomfort in an area where people are sleeping.
One of the main uses for these types of lamps is for camping, as they offer a much more stable and constant source of heat than the more compact portable electric heaters that are often used.
They are also better suited to use in small sleeping areas, away from the main living areas of a home, such as in a garden shed or a garage.
What is Radiated Heat?
When it comes to making a home heating system, one of the most fundamental types is infrared is used.
An infrared system heats up air and then brings that air through a sealed tube to a temperature where it is safe to work at.
It’s the simplest form of heating existing in man’s world and while not incredibly efficient, it can keep your house warm enough to provide for some basic needs during the winter months.
But there is a lot more to infrared than just heating. Infrared is radiated heat and is one of the most effective ways to warm your home.
In order to understand how infrared works, it’s helpful to have an understanding of how heat is radiated in general.
Heat is radiated in all directions and while it’s possible for objects to reflect and receive heat in certain directions, they cannot receive heat in all areas equally.
If two objects with similar temperatures are next to each other their overall surface temperature will always vary from what it would be if the objects had equal surface temperatures.
This is because objects with different temperatures give off different amounts of radiation.
Infrared radiation is radiated heat, and this is the real deal.
By simply placing a piece of white poster board directly beneath your radiator you can already see the radiant heat radiated from that object.
If you put a similar piece of white poster board in front of your heat radiator you can see the heat radiated from the radiator.
Now, contrast this to the amount of heat energy that your air conditioner produces.
Air conditioners are only able to produce heat to an extent that is less than the radiation coming from your radiator.
Infrared radiates far beyond the radiation coming from your air conditioner and can keep your home warm even when the weather outside is cold or dry.
Why Radiant Floor Heat is radiated heat?
Infrared is basically radiated heat, but it is also the same sort of heat emitted by your radiator.
This means that any object made of mostly metal and less viscous materials will generate infrared radiation.
The infrared rays will travel through the air until they strike something which absorbs them or passes in front of it.
This absorption varies depending on the object and this makes the temperature of objects differ from each other.
In most cases, metals are warm because they have high temperatures, while ceramics and plastics are cold because they have low temperatures.
This means that when you are using infrared heating devices you can get the same effect as if you were using a conventional heater.
There are different types of such heat sources, namely Infrared Heating, Infrared Radiant and Electromagnetic sources.
You can find this heat source in many products including radiators, space heaters, ceiling fans and many more. All you need to do is to determine which one works best for your room or house.
Basically, the use of the conventional heat sources such as radiator, convection fan, space heater and others may work effectively.
However, they are inefficient and sometimes they are not able to heat up the entire room properly. If you want to use these kinds of heat sources you should be aware of their shortcomings.
One of the disadvantages of using radiant floor heat is that it does not produce uniform heat distribution and thus it is not able to heat up a large section of the room evenly.
Radiant Heat From a Coal Fire Or a Toaster
Many people have heard of infrared heating systems such as fireplace radiators and ovens.
If you are interested in converting your current heating system to one that utilizes the heat energy of the sun, there are two options available to you.
The first option is to purchase a solar-powered infrared radiant barrier which sits on your roof or within a greenhouse and reflects the heat of the sun back into your home.
The second option is to convert your existing furnace or boiler to run on electricity that is radiated through your home.
Although the latter option may seem more feasible initially, it will be costly in the long run and may not be worth the expense if you are not going to end up using it.
Infrared is radiated heat from a coal fire or a toaster oven.
The Feeling of Warmth From the Sun is Radiated Heat
If you’ve ever read about infrared skin care, you have probably come across the term “infrared.” You may wonder what exactly this means and whether it really works.
To begin with, infrared light is the invisible ultraviolet radiation emitted by plants, which we all know is very safe for our bodies.
Infrared is simply radiated heat, the real feeling of warmth from the sun on your face. Just think how soothing it would be to have a warm, silky skin under your eyes without even having to open your eyes.
So what exactly does infrared energy do?
It activates your body’s natural collagen production, increasing the amount of collagen in your body produces.
Collagen acts like a strong, sturdy backbone for your skin.
Without collagen, your skin becomes smooth, tight and sagging, wrinkles begin to appear, skin tones start to shift and your hair starts falling out in large clumps.
Infrared is therefore very important in the treatment of aging skin.
There are many ways that you can use heat to reduce the effects of aging, but there are also many products out there that claim to be able to reverse the signs of aging by using infrared heat.
However, it must be noted that there is no scientific evidence that proves that heat from the sun causes wrinkles or age.
It is only believed that the sun’s heat does make you feel warm and sticky, and if you stay away from the sun for a longer period of time, you will feel cooler and more relaxed.
Infrared radiations however are the only way to get that “warm and sticky” feeling, so you can take any moisturizer and apply it to your face and neck before you go to sleep, and during the night when your skin needs re-hydration.
Also remember to use sunscreen or any other sunscreen containing only natural oils and don’t forget to drink plenty of water to keep your skin nourished.
How the Camera Can Pick Up Infrared Emission
This Infrared Emission is why police infrared cameras can see fugitives trying to get out of cuffs. It is a low frequency sound wave that cannot be heard by humans.
However, when an Infrared camera records the scene it picks up this sound wave and converts it into heat energy.
This heat energy can easily be picked up by any Infrared enabled devices you may have in your home. So, not only can you see people running through the front door with bags over their heads, you can pick up the heat coming from them.
This Infrared emission is why police infrared cameras are able to see individuals moving around in carports and on the grass, even though the vehicle itself remains stationary in the middle of the scene.
In fact, when the camera operates at full strength, it is almost as if the individual is in the room with the camera.
The human eye will not be able to detect the difference, which means the person cannot run away from you. It is very difficult to catch a criminal without one of these infrared cameras in this day and age.
This Infrared emission is why police infrared cameras are able to see individuals running through a carport or a large perimeter area surrounding your house.
This infrared light is the same energy that your home’s HVAC system uses to cool your house, prevent excessive temperature gain and maintain humidity levels.
The way that the camera is positioned will also influence the image quality.
If you want to see more clearly, move the camera closer to the ground, whereas, if you are looking for better detail, move it higher up in the air. This will give you the best image quality.
How Do You Know If You Are Warmer Than Other Things in an Environment You Will Radiate To?
If you are looking for a way to make you and your family more comfortable and save on energy costs, you should consider the concept of comfort heating.
This is when the air temperature you feel next to your skin determines the heat energy content of the air in that particular space.
If you are warmer than objects in that environment, you will radiate to them so as to feel cold.
The concept of comfort heating can be applied in a variety of ways including air-conditioning your room at night, or heating water in your pipes, using a heat pump to move the heat from your swimming pool or ocean back into your home or office, or even heating your garage.
In each case you need to control the temperature of the air coming into the space, as well as the amount of heat energy emitted.
The amount of heat energy you emit will be determined by the material your wall or panel surface is made of, the average air temperature in that area and the watt density of the radiator or fan used to circulate the air.
If you are looking for a way to have a warm indoor environment, then the best way to go about it is to use a combination of two or three types of radiators to distribute the air temperature more evenly throughout your space.
You will feel cold first if you are next to objects that radiate heat.
If you are warmer than those objects you will feel cold more quickly.
If you are warmer than a lot of other things you will eventually feel cold all around.
This is because the total amount of heat energy you emit is less than the amount you absorb. If you want to make sure that you do not get to hot, then you need to build up heat all over rather than absorbing it all.
Why Does the Body Temperature So Much Reluctant to Return to Ordinary?
One of the most fundamental laws of thermodynamics is that energy in a substance or system, such as your body, cannot be changed to energy in another substance or system.
This means that no matter how fast or hard you push against objects in an environment that contains more heat than you are able to give off, you will only heat up from the surface area of the objects and not from the overall volume of the environment.
In a sense, your body can only absorb and give out heat at a rate that it can generate.
This rate is usually very fast, and in a living situation your body would have already generated a lot of heat long before you were able to pick up a tool and begin to exert a force on it.
The way to stop the process before it gets too out of control is to change the temperature of the surrounding area where the objects are.
If the surrounding temperature is too cool, the objects become uncomfortable.
If the temperature is also too warm, the objects can actually get damaged because the heat energy is not properly distributed by the air.
Your body temperature can only rise to a maximum level before you have to worry about getting burned or chilled, so if you can’t prevent the temperature in the environment from becoming too extreme, then it is best to just step inside when you feel the chill coming on instead of trying to stay cool by wearing layers of clothing.
If objects in an environment are warmer than you are you will simply heat up from the outside in.
On the other hand, if the surrounding temperature is cool, your body can still keep warm without increasing your internal temperature because you are already staying within the optimal range of your natural temperature.
If you ever find yourself in a situation where you can’t figure out the difference between being comfortable and being too uncomfortable, then there is probably a bigger problem affecting your body than the outside environment.
That problem is probably your brain. It is probably that your brain is telling your body and your muscles all kinds of crazy things that it cannot make sense of. If you can understand that, then you can fix the problem.
All Objects Including People Absorb and Emit Infrared Energy
Infrared rays are invisible but they are emitted by many objects including people, animals and even computer screens.
The rays can be absorbed by objects which have a high index of thermal conductivity such as metal objects and glass.
One may ask what happens if one absorbs the heat of a hot radiator. The absorption of the heat in an object causes it to emit or radiate heat.
The heat rays are emitted or radiated from objects when they are warmed up and they then travel through the air or their nearby objects.
If the heat source is hot, one can see that the rays are absorbed by objects in the immediate vicinity of the heat source.
The rays then heat up the air or the objects close to the heat source and cause them to emit and radiate heat.
Infrared is the invisible heat energy radiation which is emitted or radiated by objects.
This is also known as the visible light and is emitted by stars, fire, and also can be seen on the night skies.
The human body emits and absorbs heat and this heat can be measured with a device known as a thermometer.
If you go out in the cold night and come back inside, you may find that the temperature has dropped because you have absorbed and emitted heat from yourself.
Far Infrared – An Overview
Far Infrared is the name given to a particular segment of the spectrum of electromagnetic radiation that extends from red light to violet light and, as expected, it also has a profound effect on the human body.
Far Infrared Light can be measured in watts per square meter or merely in feet per square foot.
One of the major benefits of Far Infrared is that it’s well suited to treating certain skin disorders such as psoriasis, acne and boils.
Another advantage Far Infrared Light has is that it has properties that make it useful in fighting cancer.
In fact, many medical practitioners regard Far Infrared Light therapy as very beneficial for both healing and preventing certain types of cancer.
Far Infrared can be classified into seven different classes based on their wavelength.
These are far infrared rays, ultra-violet, visible, ultraviolet, x-rays, infrared-light, rebates and chemotes.
Depending on how your body absorbs Far Infrared Light, your skin will react to it in a particular manner.
For instance, those with fair skin will tend to respond to Far Infrared Light much better than others, while those with dark skin will become pale or tan in response to Far Infrared. The wavelength is therefore largely determined by genetics.
Far Infrared Rays have the capability to penetrate all layers of the skin and body and therefore it has an enormous therapeutic potential.
It can destroy the primary tumor cells as well as slow down the rate of cell division and improve blood flow.
Far Infrared has the ability to eliminate existing tumors as well as prevent the growth of new ones.
In addition to this, Far Infrared Therapy has been proven effective in helping to alleviate a wide variety of symptoms such as joint pain, headaches, migraines, sleep disorders and fatigue.
How We Are Not Perfectly Adapted to Far Infrared
Far Infrared comfort heating is certainly an attractive and effective way of heating your home in winter. We feel cold in the winter and so it’s very important to make ourselves comfortable.
Far Infrared, also known as FIR, is radiant heat energy, which means that it reaches our skin directly and is absorbed by the skin before it gets to the bloodstream. This makes it very efficient for a lot of applications.
FIR can heat your home or work place to a temperature of nearly two hundred and fifty degrees Fahrenheit, far more than any other type of heating system we use.
Far Infrared comfort heating systems work on the following principle. The outer surface of a Far Infrared comfort heating panel is heated from beneath using Far Infrared radiation.
A special glass sphere holds the radiation and this sphere is completely surrounded by an inner sphere of glass.
When the outer surface of the panel is heated, it glows with radiant heat energy and this heats up the inner sphere.
By installing a Far Infrared heating panel around your home you will be able to achieve a high, comfortable temperature, often up to sixty degrees Fahrenheit, and this will make you feel warm, cozy and enjoyably cool.
You will immediately notice the difference between a warm room and a cold one, your skin will feel smooth, warm and inviting, your hairs will be soft, and your muscles will ache less.
Far Infrared works much like traditional heating, but instead of radiating heat energy directly into the air, it sends radiant heat energy down through the glass of the panel, which warms the air instantly.
This is the perfect way to heat up your home, make it more comfortable and make it easier and cheaper to heat your home.
How Far Infrared Radiation Absorbs Water And How Is It Affected By Water Beads?
Body Fat The more body fat you have the less your skin will be able to absorb Far Infrared especially far-infrared rays.
As you lose body fat, your body will naturally reduce its ability to retain moisture.
This can result in sagging and wrinkled skin. So as soon as you begin to shed body fat you should start working towards keeping your skin hydrated and moisturized.
Exercise Our bodies produce sweat as part of our natural function.
Excessive sweating can cause dry skin and can also result in dehydration. However, as water is absorbed through the skin and into the blood circulation the body loses less water and therefore the skin is able to retain more water and thus retain its elasticity and smoothness.
Therefore, you should aim to keep your body as hydrated as possible and if sweating is a problem you should consult with your doctor about the best way to reduce excessive sweating and keep your skin hydrated.
Also, increasing the amount of exercise you do will help your body to retain water and will also improve your skin’s elasticity.
The Importance Of Hygiene If you think water beads are interesting, you should know that Far Infrared rays have been shown to kill cancer cells.
It is these far-infrared rays that are able to penetrate through the skin and enter the blood stream and this is the way that the Far Infrared radiation is able to destroy cancer cells.
How Does the Sun Generate Heat Energy?
Heat energy is one of the three fundamental types of electromagnetic radiation that can be emitted by any electrically conductive body or conductive substance.
There are many kinds of heat energy, all of which have different uses in different industries.
The type of heat energy most commonly found in industrial settings is radiation heat, which can be used for a variety of tasks.
Heat energy passes through a metal plate or through a layer of powdered metal.
When heat energy passes through any of these substances that it meets with, atoms of various wavelengths are excited by the interaction, and this excites molecules in the object which vibrate and gain heat energy as the energy passes through.
The process is similar to the way that light can be reflected from metal plates so that we can see the heat radiated from them.
This process only happens at very high temperatures, as the metal plates become very soft when they are heated to temperatures above approximately 1800 degrees Celsius (which is essentially what metal doors, cabinets and plates get when you are baking).
The difference between the reflective heat energy produced by a metal plate and the heat energy emitted by a coal can be found in the fact that the former is actually convective heat, and the latter is conductive heat.
It is because of this that glass plates cannot conduct heat but have very good reflectivity. Another surprising fact about the sun is that it is not hot, but rather cool, while it is much hotter than the earth’s average temperature.
Solar power has recently become very popular as a way to save energy and prevent global warming.
The solar panel works by converting solar heat energy into electricity, which can then be used to power various household items.
However, as yet there is no practical use for solar power on the grand scale.
Does Heat Energy Exist?
Comfortable and warm temperatures can be achieved by utilizing alternative energy sources such as heat energy.
This method is very similar to the process of convection, which is why it is so prevalent in air conditioning systems.
Heat energy is usually absorbed by objects when they are warmed up, which then passes through a cooling system and then back into our living spaces.
However, it can also be lost by objects even if they are heated up since heat energy is lost in thermodynamics.
In this case, a warm room or house is still comfortable because the air surrounding them is cooler than the air mass that surrounds it due to its lack of heat energy.
The way how heat energy is released has to do with a few factors including the characteristics of the building’s interior as well as the overall exterior temperature.
For buildings with a high internal temperature, the amount of heat energy released is substantially higher compared to those buildings with a lower temperature.
On the other hand, heat energy is also lost from cold air mass even if it is heated up.
The reason behind this is that heat can be absorbed only to a certain degree by objects, and once the heat is taken out of an object, this absorption stops.
Because of this, air-conditioning systems can only cool a small portion of a given area while a comfortable breeze can circulate around for hours at a time without moving air.
To solve this problem, comfort heating incorporating panels has been developed.
These panels are typically placed on the outer portion of the roof.
These are typically made out of a special material that allows heating energy to transfer only a limited amount of energy to the building’s core because heat energy is not a volume in relation to a unit of space.
In this way, heat energy is released regardless of the surrounding air temperature because a small change in the temperature will not affect its level too much.
As a result, heat energy is able to be used for a comfortable environment in many places in buildings.
Infrared Waves Travel Through the Air and Can Warm Up the Air in Your Home
Infrared waves travel through the air and they come into contact with objects to heat them.
This makes the objects retain heat long after the waves have disappeared from the surrounding area.
If you place a warm cloth on your abdomen after you have had a swim, the heat energy is still there and this can be comforting.
In order to get this comfort heating technology to work within your home, you need to place a panel surface in the middle of the room.
You will need an absorber plate and then the panel surface should have a thin metal layer.
The heat source for this panel surface is an electric heater.
To keep the heat source going all the time, you would need to use a constant voltage device. The heater could be constructed using aluminum foil, a glass jar or any other transparent material.
Another way to use the heat energy generated by the electric heater is to use it to warm up the air in the room.
For this to work properly, you will need a fan to blow air across the surface and this should be designed so that it can handle larger volumes of air pressure.
The heat generated by the infrared waves is very powerful and when this type of wave hits an air molecule, the molecule will absorb the heat energy.
Does Radiant Heat Really Makes the House Warmer in Winter?
Radiant heat is one of the latest buzzwords around the home design and construction world.
Most people feel that if they have a big fireplace in their living room, then it will help with heating up the entire house.
If the fireplace was to use radiant heat, it would certainly distribute warm air throughout the house, and that would make the rooms much cooler during the summer months.
This isn’t what happens though. When you look at the radiant heat, you see that it doesn’t heat air that holds little heat, but rather it helps to distribute heat that already exists.
You see, radiant heat is different from traditional heating methods, because it doesn’t work by spreading the heat around your house.
Traditional heating methods are more or less okay at making the entire house hot; radiant heat merely helps distribute that heat more evenly throughout the entire house.
With that said, you will find that when you put a fan in front of your fireplace and turn it on high, you’ll still get the warm air that’s distributed throughout the entire house.
