Fan Heater Classification
Fan heaters are classified by installation method, scope and heating element. By the type of regulation they can be divided into remote and mechanical.
Fan heaters with a remote control are more expensive, but they allow you to manage their work without getting up and without taking off a warm blanket.
Next, the features of the devices in the context of their classification are analyzed.
By scope of application, fan heaters are divided into:
Industrial models, unlike household ones, are designed for round-the-clock use without affecting the durability of the work.
The power of each category is also different due to the possibilities of home electrical networks.
Automation on apartment electric meters works even with long-term loads of 3.5-4 kW, so the power of domestic fan heaters rarely exceeds 2.5 kW.
Heaters for industrial use are not limited in power consumption and usually have the ability to connect to a network voltage of 380 V.
High-performance space heating systems are sometimes called heat guns.
By the nature of the installation
By the method of installation, fan heaters are classified into the following types: stationary and mobile.
Stationary, in turn, are divided into:
- wall mounted;
Mobile devices can be installed anywhere in the room and even hung on hooks. These include desktop heating systems.
Mobile fan heaters are compact, lightweight, and their power is usually limited to 2-2.5 kW.
Floor fan heaters often look like vertical columns. Compared to mobile devices, they produce less noise and are more productive.
Some floor models have a movable swivel housing that allows you to direct the flow of warm air in several directions. In the summer they can be used as simple fans.
Wall-mounted fan heaters are reminiscent of the indoor unit of an air conditioner, but they do not supply air flow to the side, but down. They are often used for a thermal curtain over the entrance doors to the room. Wall models are controlled using the control panel and mechanically.
Ceiling fan heaters direct the flow of warm air in all directions at the same time, therefore they are recommended for heating large rooms with high walls.
Stationary fan heaters are relevant in rooms with a constant need for heating. And if heat is needed for a couple of weeks or just for heating your legs, then the mobile option is the best choice.
By heating element
The heating element in the fan heater can be as follows:
- ceramic heater;
- water heat exchanger.
Devices with a water heat exchanger are usually hung on the walls and integrated into the room heating system. Their fan serves to accelerate the circulation of air in the room, if necessary, rapid heating.
A nichrome wire spiral is the oldest and cheapest heating element that has been used for over 100 years. Its surface is heated to 800 ° C, which leads to the burning of dust contained in the air and the appearance of a slight burning smell.
Burning out the spiral can lead to the ignition of the device, therefore this type of fan heaters is the most fire hazard.
Heating elements have the form of a tube that contains a nichrome wire inside and is filled with a heat-conducting substance. The temperature of its surface rarely exceeds 450 ° C, so the dust does not burn out upon contact with the tube.
This makes the heater more comfortable and safe compared to the spiral, no odors arise during its operation. The cost of fan heaters with heating elements is slightly higher than with spiral heaters.
Ceramic heaters have radiator grilles made of semiconductor material, the surface of which is made of heat-resistant glass ceramics. These products are obtained by spraying powder on a metal frame, followed by sintering in a furnace.
The surface temperature of ceramic heaters does not exceed 100-150 ° C, and high heat transfer is ensured due to the large area of contact of air with a hot coating. Such heaters are safe to operate, but require regular manual cleaning and are more expensive.
Device and principle of operation
A fan heater, by definition, must generate heat that is carried around the room by a fan.
Therefore, any such device consists of three required components:
- A heating element.
The housing of low-cost models is made of cheap plastic, which during long-term operation can be deformed and even fused. It is advisable to purchase fan heaters in a metal shell, which is able to limit ignition in case of overheating of the internal elements.
The fan can have different power. The higher it is, the faster air is blown through the heating element, lowering the temperature of its surface. The impeller rotation speed is often changed using the knob.
Fans can be of two types:
- axial (lobed);
Axial fans have 3-8 blades of the usual look, which are made of plastic or metal. Such impellers are mounted on portable models. Axial fans are noisy, but unpretentious in maintenance. They should be periodically lubricated with machine oil.
Tangential fans have the form of a cylinder with 20-30 blades in the form of longitudinally arranged strips. They are placed mainly in wall and vertical models.
The cylindrical design provides quiet operation and high performance. The disadvantage of tangential fans is the need for periodic cleaning.
The heating elements are located in front of the impellers, which allows them to cool evenly.The rear position of the fan also contributes to the capture of more air.
In addition to the main components, heaters can have additional equipment that extends their functionality.
Fan heater selection criteria
Choosing a fan heater is not an easy task. The product range is large, and prices for similar models can vary significantly.
Next, we will consider what characteristics of the heater to pay attention to when buying, in order to choose the most useful model and not overpay for unnecessary functions.
The main factors that determine the choice of fan heater are:
- power consumption;
- type of heating element;
- availability of additional functions;
- operating modes.
The influence of each of the listed factors on the choice of a heater should be considered in more detail.
Criterion # 1 - power consumption of the device
Only 10-12% of fan heaters on the market have a capacity of less than 2 kW, but they also have their own customers.
Heaters with a power of 1-1.5 kW are recommended to be purchased in such cases:
- The house has an old aluminum wiring, which can catch fire from high loads.
- Simultaneous inclusion of 2-3 fan heaters in one room or apartment is required.
- The size of the heated room does not exceed 10 sq.m.
- The device will be used for additional heating with the existing heating system.
The minimum power of the fan heater is calculated based on the norm of 1 kW per 25 cubic meters. premises.
It must be remembered that ordinary sockets are designed for a maximum current of 16A, which corresponds to a power of 3.5 kW equipment. Therefore, heaters with a consumption of more than 3 kW cannot be used for a long time at home.
Criterion # 2 - type of heating element
The most common are fan heaters with heating elements in the form of a heating element, a spiral and a ceramic lattice. Budget models of heaters are equipped with a nichrome spiral.
You can choose such a heater in such cases:
- There is no financial opportunity to buy a more expensive model.
- The device will be constantly in sight.
- Using a heater will not be around the clock.
- Fan noise is not critical.
Cheap fan heaters with a nichrome spiral are quite fire hazardous, so you need to buy them only under the listed conditions.
The best option for a heater is a device with a ceramic heating element.
They are more expensive than spiral ones by 20-50%, but have a number of advantages:
- They have high fire safety.
- They can be operated around the clock.
- Do not burn airborne dust.
Fan heaters with a heater are located in practicality between spiral and ceramic. You can choose them if you have good additional functionality and reasonable prices.
Criterion # 3 - fan and heater operating modes
The number of fan heater operating modes directly affects its resource and profitability.
Typically, heaters have three schemes for regulating their work:
- change in fan speed;
- temperature control of the heating element;
- automatic maintenance of the set room temperature by periodically turning the device on and off.
Changing these parameters can occur by discrete or smooth movement of the adjusting knob. A more precise setting allows you to create the desired temperature regime in the room, without wasting excess electricity.
To change the fan rotation speed, you can use a special device - a regulator, the device of which and the connection rules we reviewed here. The regulator can also be used in the assembly of a homemade heater.
Some models of the fan heater have a built-in timer that allows you to heat the room just before a person arrives.
Criterion # 4 - additional functionality of devices
The basic functionality of fan heaters usually involves the presence of knobs for controlling the power of the heating element and the speed of rotation of the impeller. But manufacturers equip heaters with other devices so that their products have advantages over competitors.
The presence of additional functions for the fan heater is an indisputable advantage, therefore, within the existing budget, it is recommended to buy a heater with the maximum number of them. But first you need to assess the real need for additional equipment.
Such additional equipment includes:
- Swivel mechanism that allows you to direct warm air in different directions.
- Low noise bearings.
- Protection sensors that turn off the device when capsizing or overheating. They are relevant for families with small children and pets.
- Splashproof housing.
- Remote Control
- Air filters.
Cold mode is also actively used (without turning on the heating element).
As for such a function as ionization, experts recommend buying a separate device designed for the ionization process for these purposes. Arguing that special devices designed to ionize the air do a better job of this.
Recommendations for choosing a household ionizer we gave in this article.
Each additional equipment adds a certain amount to the cost of the fan heater, so the heater’s functionality is limited only by the planned purchase budget.
