How to choose a heater with a fan

Today you can find a wide range of heaters designed for different needs of users. The electric heater with a fan won a good reputation among its "comrades". Such devices can easily raise the temperature to the desired degree in any room.The fact is that after switching on, the units begin to immediately blow warm air.

What are they

The working scheme of the heater with a fan looks like this. Inside the equipment there is a fan, the blades of which drive the cold air to the heated heating elements - the spirals.That, blowing spirals, heats up and rushes into the room, raising the air temperature in it.

Stationary models do a better job. They warm up the room more evenly due to the fact that they have a turning mechanism.

The advantage of the device is that it is able to quickly create a favorable temperature in the room. In the summer, similar devices can be used. as a fan, saving the family budget. You pay for one device, and you get two at once: a heater and a fan.

The device consists of:

• fan;
• enclosures;
• heating elements (spirals).

When buying, pay attention to the body of the product: it must be made of high-quality plastic that can withstand minor shocks and elevated temperatures.

Choosing a fan heater

All fan heaters differ in the following criteria:

1. According to the type of heating element.
2. By type of fan.
3. By design.
4. According to the control system.

Types of heating elements

All heaters equipped with a fan differ in the type of heating element. There are three of them:

• spiral;
• tubular;
• ceramic.

We will dwell on each type in more detail so that you can form your opinion.

Spiral

In most models, spirals are madefrom nichrome. Such an installation is a ceramic base wrapped with thin wire. You can find devices enclosed in a glass tank, but with an open heating element.

Devices in which the wire is not protected, are very dangerous. After all, a spiral can heat up to 1000 degrees in a matter of minutes, and in the event of equipment tipping to the floor, there is a possibility of fire.

Another disadvantage of an open spiral heater isunpleasant smell. It occurs due to the fact that the dust deposited on the surface of the nichrome wire begins to glow after turning on the device.

There is a myth that such models burn oxygen. Hurry to dispel it. The spirals are heated by electricity. No open flame capable of burning oxygen is observed. Therefore, we can conclude that this statement is nothing more than an advertising move in order to attract the attention of buyers to other types of devices.

Glass ceramic

Fan heaters equipped with a glass-ceramic heating element are much safer than spiral ones, since they only heat up up to 150 degrees.

The glass-ceramic element is produced by pressing the powder and further calcining it at very high temperatures. On the finished part, you can see a huge number of small holes through which air masses pass.

Such models heat the air much faster, due to the fact that the area of ​​the ceramic plate is much larger than nichrome plate.

A significant disadvantage of such models is in their valuewhich is three times higher than that of heaters with a spiral element.

Tubular

TEN is a tube of quartz or metal. Inside it there is a rod - wire or graphite. Quartz sand and manganese oxide are buried between these elements. In most cases, the heater filler is made of quartz, and the inner core is made of nichrome wire.

The quartz sand serving as a filler is responsible for the uniform distribution of heat over the surface of the heating element. This design heats the heating element. up to 500 degreesthat allows you to quickly warm the air in the room. However, the price of such a device is somewhat higher in comparison with spiral heating elements.

Heaters equipped with heating elements are called "Heat guns"it is most reasonable to use them in warehouses, construction sites, production, but not in everyday life.

Types of fans in the heating device

Fan heaters also differ in the type of fans with which they are equipped:

• plastic (they are equipped with small devices);
• metal (in large appliances).

There are two types of fans:

1. Axial. They equip small mobile devices. Its blades have a standard design. True, the operation of heaters equipped with axial fans, can not be called silent.
2. Tangential. It is a cone of oblong shape, equipped with about 30 blades mounted parallel to each other. Devices with a tangential fan are characterized by high performance and quiet operation. But since the length of the cone cannot be called small, only stationary electric heaters — columns — are equipped with this design.

Heaters design

Fan heaters are classified according to the method of execution. So, in stores you can find two types of devices:

1. Mobile.Equipped with an axial fan. Have a small capacity - up to 2 kW. The undoubted advantage of mobile devices can be called the ability to move to any part of the room, small size and weight.
2. Stationary. Power devices - from 1.8 to 2.6 kW. They are equipped with a tangential fan, which in column-type heaters is installed vertically. The performance of the devices is much higher. Quite often, such units are equipped with an automatic swivel mechanism. They use stationary electric heaters in stores, cafes, restaurants, often at the entrances - as a heat curtain, so that they cut off the cold outside air.

Control system

Fan heaters also differ in control method. It happens:

1. Mechanicalcontrol, which is most often equipped with mobile devices with an axial fan.
2. Electronic- heaters of this type are much more expensive than mechanical ones.

Modern models are often completed control panelthat is undoubtedly very convenient.

How to choose a good fan heater

Going to the store for shopping, check out some of the characteristics of fan heaters to choose a good and durable option.

When choosing a device, pay attention to the following points:

1. Power.
2. Type of heating element.
3. Mode of operation.
4. Rotating base.
5. Type of fan. Of course, the best is tangential.
6. Availability of automatic shutdown sensors. In case of overheating or overturning, the device will turn itself off.
7. Thermostat.
8. The case having protection against moisture and splashes.
9. The presence of a moisturizing filter. Positive effect on human health.
10. Remote Control. Adds ease of use.

Before you buy a device, calculate the power it should have. To do this, measure the desired room.

For every 10 m² with a ceiling height of not more than 3 meters, 1 kW of power is required.

Conclusion

There are many types of heaters. The fan heater perfectly copes with its main task both in apartments and non-residential premises, shops, hangars, garages. The main thing is to take into account all the characteristics that the heater has.

The best is fan heater, the heating element of which is made of glass-ceramic. He is the most secure. In addition, when the device is no smell.

Before buying, make sure that the fan heater is equipped with a glass-ceramic heating element, and not cermet. And remember about security measures. In no case do not dry things on electrical appliances of a similar purpose: it may end in fire.
