Autonomous or centralized stationary heating systems are not always able to provide adequate heating of the room. This applies to industrial and public premises, offices, retail outlets. Used developments of various industrial climatic equipment can improve this situation.
If we talk about residential premises, then the consumer needs a compact device, with low energy consumption and high efficiency - equipment that can heat the estimated volume of air inside the room and ensure uniform maintenance of the set and reached temperature. Safety during operation in all modes is also an important detail when choosing equipment.
What is a mycothermal heater
The main difference of the mycothermal heater is the design of the heating element. The substrate or base for mounting the heating element directly is made by pressing a mixture of micanite and a heat-resistant binder. The shape and configuration of the base may vary.
REFERENCE! Mikanite (mica paper) - thin, flat particles of mica. It acts as a dielectric, has high thermal conductivity and thermal conductivity.
A nichrome spiral, solid nickel plates with an external coating (oxidized alloy of tin, zinc, iron), with terminals for connection, can be attached to the substrate. The outer layer is a thin layer of micanite covering the heating elements, on which a concentrator and infrared reflector are attached, and another layer of mica paper is applied on top of them. To create additional structural rigidity and increase heat transfer efficiency, it is possible to install an additional element, an aluminum plate.
ATTENTION! Do not try to independently improve the design of the emitter. The slightest changes in the design of reflectors, the outer layers of micanite leads to failure of the device.
Each developer and manufacturer prefers not to disclose all the secrets of the production of these elements. But the studies show that most of the proposed models are both sources of infrared radiation and heating elements.
The heating function is based on the ability of infrared waves to penetrate to a certain depth (depending on the material) of the surface of objects encountered along the path of their propagation. Wave energy helps to increase the temperature of these objects, from which, according to physical laws, the surrounding air space is heated.
The metal case with diffusion holes is practically not an obstacle during the passage of waves. Inside the case has a heat-insulating coating. This is necessary due to the high temperature of the radiator of the heating element itself (up to 400ºC). Due to additional insulation, the temperature of the heater body does not exceed 50-60ºC, which prevents the possibility of accidental thermal burns. The case can have floor and wall options for construction.
Advantages and disadvantages
The advantage of using mycothermal heaters is:
- the ability to quickly achieve maximum power (operating mode);
- noiselessness;
- compactness;
- light weight.
In addition to this, the operation of the heater does not affect the humidity inside the room. The disadvantages include the appearance of a smell during operation - due to burning of dust that has fallen on the plates and a small heating area - the device heats only the area to which it is directed.
What is a convector
The principle of operation of this type of electric heaters is based on the properties of physics and aerodynamics. Warm air is lighter than cold air and its flow is always directed upwards. Sparse space is filled with cold air. The convector contributes to this process.
The convector design is an electric heating element (spiral, plates) mounted in the housing. The housing has intake openings or blinds of various configurations located at the bottom of the device, and output, for the exit of the heated air stream. The temperature of the air heating, when passing through the heating element or along the heating element, depends on the power of the used heating elements. Most modern heaters of this type are equipped with a fan. This is done to increase the speed of convection flows and at the same time protects the heating elements from overheating and failure.
Design options depend on the type and shape of the heater used. Convectors are available in floor and wall versions. All modern devices are equipped with additional controls and protection. Operation modes can be set manually or using electronics and automation.
Advantages and disadvantages
The main advantage of convector type heaters is the ability to evenly distribute warm air masses indoors. As you know, the main feeling of warmth and comfort gives the surrounding heat. Oil and infrared heaters that heat small volumes of air masses that are in direct contact with sources of thermal radiation can give such a sensation only during continuous operation.
The disadvantages of this equipment include only the ability of the heating element to “dry” the air.
What is better to choose depending on a specific task
If it is necessary to create a small cozy comfort zone in a short time, then the choice of a micathermic heater will be optimal. Moreover, in the process of further work, he will also warm up the entire room. If it is necessary to heat the room evenly, then the use of a convector in this case will be preferable. Another plus in favor of the convector, its lower cost.
