Ceramic heater: principle of operation, types, advantages and disadvantages
Unfortunately, the central heat sources are notthey can always fully fulfill the tasks assigned to them. Therefore, it is often necessary to resort to an additional method of heating. Solve the problem with heaters, which are on the market in the widest range. One such device is a ceramic heater.
Features of the design and principle of operation
The basis of heating technology of this type isceramic heating element. And it can be used in absolutely different heating devices, differing not only in appearance, but also in the principle of action.
Based on the method of heat supply, the devices are divided:
- On infrared ceramic heaters - heat objects by infrared radiation;
- Ceramic convectors - work on the principle of forced convection.
Ceramic IR heaters are equipped withheating ceramic tube with a nickel-chrome spiral inside. They can be hollow, bulky or gas. Such devices, although considered the best among the analogs, are not so active, because they are able to heat only a certain area located in the zone of infrared rays.
To date, great interest isceramic panels (plates), which allow to provide a considerable area with heat. The peculiarity of heating consists in the fact that the ceramic plate acts simultaneously in two directions: as a convector and as an infrared heater. Inside the structure there are small fans that run the air masses through the heat exchanger from the ceramic and evenly discharge into the premise a warmed-up air flow. The ceramic plate has a built-in thermostat, which allows to set the optimum temperature and protect the device itself.
Classification by source of energy
Heaters can work not only from electricity, but also on liquefied gas.
Depending on the energy carrier, ceramic heaters are:
• Electrical. The most practical and common. Because of the simplicity and ease of use, electric ceramic heaters are often used to heat children's rooms. They do not dry the air and do not consume oxygen. In addition, they can be used in places with high humidity.
• Gas. They work at the expense of energy obtained by burning high-caloric propane-butane and are inferior in performance to electric ones, although they are cheaper. The main component of the device is a ceramic panel, inside of which flameless combustion of fuel takes place. The gas ceramic air heater assumes the use of a gas cylinder from which the fuel flows through the hose to the burner. Most often, such units are used for heating verandas, summer cafes, garages and storage facilities.
Classification by type of placement
By type of installation ceramic heaters are:
• Desktops are compact devices that tend to have little power and are designed to quickly heat small rooms.
• Wall heaters on the outside resembleair conditioning and installed at any height. Such a ceramic heater does not occupy a useful space and is most suitable for warming up an average area.
• Floor versions are the most powerful and able to heat rooms with different squares.
Benefits
To the advantages of heaters with ceramic elementsit is possible to attribute high efficiency, safety and reliability of use, creation of an optimally comfortable microclimate, rapid warm-up of the room. In addition, compared to traditional oil heaters, they consume a third less electricity.
Ceramic heaters have a high levelfire safety. The built-in thermostat provides protection against overheating. Among other things, such heating devices are the only ones that can be used in rooms with high humidity. Many models are equipped with antibacterial protection and ionizer.
An additional advantage of ceramic heaters is the possibility of using them in the hot season as a fan.
disadvantages
Like all other heating appliances,ceramic heater has its drawbacks. These include the local effect of a number of models, as well as the rapid cooling of the room after the device is turned off. Many buyers are confused by the fact that the price of ceramic heaters is significantly higher than other heating appliances. In fact, with so many advantages, this is fully justified.
Recommendations for selection
Many people ask: in which cases is it worth buying ceramic heaters? The testimonials indicate that this climate technology is excellent for heating bedrooms and children's rooms, since it practically does not dry the air. Some prefer to use ceramic appliances in the bathroom because of their resistance to moisture.
However, it is important to understand that the ceramic heater can not completely replace the main heating system in view of its powerful characteristics. He is only able to supplement it.
When choosing a device for additional heating,first of all, it is necessary to consider the area of the room Proceeding from this, the optimal type of climatic equipment and its power are selected. So, the ideal option for a small room is a wall heater, which will save space and effectively warm it up. In addition, the degree of closeness of the room should be taken into account: electric ceramic devices are suitable for internal heating, and gas - for open areas.
