How to choose the heater for the house or apartment - a form of comparison and selection criteria
heaters are one of the most popular heaters.After all, they are the cheapest, and buy them during the autumn-winter season is possible in every store that sells household goods.But not everyone knows that not only the design and color of different data heaters - what is hidden inside the body, it is much more important.After all, it is "filling" determines how the device will last and how it will work reliably.Consider how to choose the heater, having studied all their types, as well as the most important pros and cons of each.

How does the heater and that he had inside
in each device of this type has an ordinary fan,
heater is good because it can create a comfortable temperature in the room fast enough.If the air flow generated by the fan, has a narrow directivity, it is possible to almost instantly warm air only where it is needed.In the summer, these heaters are easily converted into ordinary fans - this feature allows you to save money and space in the apartment, and the money in your pocket.
design any fan quite simple and includes only three items:
- heating element;
housing must be strong enough, it is made of plastic, able to withstand some bumps and knocks.Also, in case there are metal parts.Next, let's talk about what kinds of heating elements used in the heaters of this type, as well as about the design features used in their fans.
comparing existing types of heaters
1. Basically, the different heaters - this type of heating element.It can be a spiral type, and the ceramic tube.We characterize each of them to see which element should be equipped with the best heater.
spiral element is made, usually nichrome.It is a thin wire is wound around the ceramic base.Open design is no secure wire coils and closed - the same coils placed in a glass tank, inside of which there is no coolant.This wire is heated up to 1000 degrees, which is not safe - because rollover unprotected or poorly protected heating element can cause a fire.
Moreover, with time on the surface of nichrome wire accumulates dust which smolders and stinks when you turn on the heater.After all, it is due to structural features have to operate at high temperatures.Nevertheless, an open flame, where possible burning of oxygen, there will never - heating coil occurs under the influence of electricity.Therefore, the claim that this type of heater is still burning oxygen is obviously false.It is on hand vendors selling other models, so they spread rumors.
Glass-ceramic heating element works differently than nichrome.He warms no more than 150 degrees, so these heaters for home safer.Ceramic part manufactured in several ways, but most often used is as follows: the powder is pressed, and then fired in a furnace at high temperature.In the finished ceramic plate can be seen a large number of tiny holes through which the air is, driven by a fan.The air mass is heated faster than nichrome spiral - because the area of the ceramic plates is much more than the area of the spiral or tubular PETN.
however, have heaters with ceramic element and a significant negative cost.So, if you compare them with the device, air is heated by a spiral, it appears that the latter are cheaper by about three times.It should be noted that for the manufacture of heating elements used not only glass-ceramics and cermets.They have a similar structure and characteristics of the spiral elements.The difference is that the spiral of nichrome is inside the housing is not made of glass, and ceramics.Due to this increased fire safety.

Ten (tubular heating) - this is a tube made of metal or quartz, inside which there is a graphite rod, or wire.Between them is filled quartz sand and manganese oxide is added.Typically, the heating element has a filler quartz rod inside - of nichrome wire and the filler is silica sand.It is needed to heat produced by electricity is distributed uniformly over the entire area of the heating element.Through this structure, PETN is not heated to 1000 degrees, as the helical member, but only up to 500 degrees.Accordingly, the double and increase service life.Unfortunately, the price will rise.
Since the heating element is able to multiply the power heater, such devices are not longer applicable in the home and in the workplace, garages and outbuildings.There they are called "heat gun", having power of 2.5 watts and higher.
It looks like heat gun.
2. Differ heaters Heat fan type and the built-in fans that are made of plastic (for small devices), or made of metal.Fans are only two species.
Axial fan usually quite small, but noisy, it has a traditional type of blade.He put on a device that is supposed to move.
Tangential fan similar to the cone of oblong shape.This cone has twenty or thirty blades parallel to each other.This type of fan is characterized by good performance and quiet operation.Air at one time it spends more than the axial model.But due to the long length of the cone so the fan can only fit in the column-heaters that are designed for fixed mounting on the floor or on the wall.
3. 's just following difference heaters from each other is their performance - mobile or stationary.The latter, in turn, can be wall or floor.
portable or desktop, devices are rated from 400 watts to 2 kilowatts, small size and weight.To establish and collect them easily, but they have one drawback - noise.After all, these devices are always axial fan.
mobile, portable heater.
have heaters, made in the form of columns, tangential fan is standing upright.The power of these devices can vary from 1.8 to 2.5 kW, and the productivity is higher than that of mobile devices.Often, they built an automatic rotating device.These instruments can be used not only as heaters for the apartments, but as curtains in shops, offices and restaurants.And they cut off the cold air from the street at the entrance to the room.

4. management system at the heaters can be mechanical or electronic.Some models have a control panel, which creates some additional convenience of use of this device.

electronic system with remote control.
What should I consider when choosing
heater power required
If the ceiling of the apartment has a height of 270 centimeters, the power of the device is determined as follows: for every 10 square meters area needs 1 kilowatt.However, back to back is not worth taking - it is better to take the device with a power reserve of 1.3 or even 1.5.This is especially useful frosty winter.
Of course, it is best to choose the fan heater, which uses a heating element of the glass ceramic.He and dust will not burn, exuding an unpleasant odor and is much safer instruments of another type - spiral and heating element.
Just do not fall for the tricks of vendors.They are trying as quickly as possible to sell the goods, may be slightly slukavit and say that the heater is equipped with a ceramic heating element.Only umolchat thus, what is meant is not glass-ceramic, and cermet, that being said, two big differences.So simple advice before choosing a ceramic heater - carefully read the instructions.If the ceramic plate hardly heats up, the metal-ceramic element is only slightly better than the spiral.
number of modes heater should ideally be as much as possible.It is convenient - without using a thermostat, you can immediately adjust the temperature needed for the feeling of warmth and comfort.However, the maximum possible number of modes - three, in the current model is no longer given.
Very well, if heater contains the following functions and devices:
- rotating base will allow warm air to reach the far corners of the room;
- fan that little noise - ideally - a tangential;
- off sensors that trigger a rollover and overheating of the device;
- Ability to maintain the temperature at plus 5 degrees, almost without expending energy (antifreeze function or frost);
- housing with protection against splashes (handy in the bathroom);
- humidifier and filter allow to maintain a healthy environment;
Now that we are acquainted with the way the heater is chosen, it's time to list a few simple rules.They will remain intact as you and your home, and a device for heating and creating in it a comfortable temperature.So, it is necessary to know very little.
1. Remember heaters do not like being dropped or dragged by a cord.Especially good when the device is tilted in the ON state.
2. can not pour liquid instrument (even plain water) and to include it where too wet.
3. Putting heater should be no closer than two feet from any object.
4. If someone wants beauty and comfort, and he thinks of the heater cover with a cloth, it may happen that it will have to bitterly regret.Doing so may lead to overheating of the device, and even a fire!
