With the arrival of cold weather it is often so that the central heating does not cope with heating apartments, indoor temperature is too low, the residents suffer from cold, risk of catching cold. Not surprisingly, many go to the market or the store to buy a spiral heater. This device is widely known from Soviet times, it has proved quite effective and convenient in operation. But whether it is relevant in today's world, among the many competitors?
competent approach
The shops and the market offers a variety of devices in this group, and different specifications, and cost, and appearance. Unfortunately, the popularity of technology explains the large number of fake and low-quality products, which is not only inefficient operation, but also dangerous. Consequently, in the process of buying definitely need to make sure you have certificates of quality, product authentication. It is not superfluous to conduct a test run of the heater, heaters.
During operation, there should be no background noise, crackling and smell. Body parts and the cable must not be heated even when operating at maximum power, if the heating occurs, it is likely that the problem relates to the electrical part, and it is fraught with danger fire.
Design features: internal modules
So modern device consists of the following components:
- Spiral. Metal helix is inside a solid tube of quartz. If the device runs at maximum power, the spiral must not be heated too quickly, as this affects the durability. The slower heats up, the longer is the technique.
- Fan promotes even air distribution throughout the room, and also increases the rate of warming. The main requirement - the silence of work, in this case, even at higher speeds, this parameter should remain unchanged. If we talk about portable models, then they should work equally quietly, regardless of the angle. Mandatory requirement - the total absence of vibrations.
- humidification system. Studies show that even the most modern modifications reduce some content oxygen in the air and fall provoking humidity indoors becomes slightly stuffy and uncomfortable. To compensate for this phenomenon, the device put on Parts, artificially increasing the moisture content. Hydration takes place by ultrasound, and evaporation. Most often used the second method. In the context of the shop to accurately determine the effectiveness of the module is quite difficult, you can only visually assess how quickly and significantly decreases the level of water in the tank. Of course, it is important not only to the effectiveness of a supplement, but also ease of use. Evaluate how easily fill water into the reservoir. Most current models of heaters automatically block the work of the main element in the open neck, funnel equipped with special preventing splashing, ingress of liquid droplets on a hot spiral.
Design features: external modules
Outside there are the following elements:
- Directly to the housing. You should not be guided solely by appearance, although it should not be forgotten. Design patterns can be easily estimated from the photo. The heater should be complementary to the existing interior space, look at it organically and naturally. From the standpoint of design, the most important requirement - the presence on the body protective lattice that excludes direct access to the coil. Cell size should be about 5 millimeters. Materials for housings protrude plastics and metals. Plastic must be non-combustible, but it is rather difficult to verify, some producers cheat buyers using standard plastic, which quickly deform under high temperature. Thus, it is better to opt for the metal analog, it no additional testing is not needed.
- Toggle switches and switches. If we talk about the budget models, then they set the switches of the mechanical type. Check how smoothly rotate the handle as easily go the switches, how well they respond to your actions. If, during the start-up device causes interference for household appliances (TV or radio) to buy it is not necessary, it is likely that in a month will have to buy a new use instance. Furthermore, obstructing talks about the serious structural problems that could trigger a fire.
- Cable. The main parameter - the length of which should be sufficient for a free connection to the outlet. Unfortunately, on many models length is limited, so connection scheme of the modern spiral heater often can not do without the additional use of an extension cord. However, there is a perception that the short cord - a sign of low-quality products, so it is best to choose a model that has a cable length of about 180 centimeters.
additional elements
Additionally, the following parts are installed on a device:
- Limit switches. As a rule, mounted on legs emergency shut off device when dropped or unstable reaching a dangerous position.
- Air Filter need models with artificial blowing.
- Automatic protection against short circuits and excessive heat. This spare part can be attributed to the category of necessities, but, oddly enough, often it is not even on the expensive elite units.
- temperature sensor facilitates the operation, when the room given climate, the unit automatically turns off.
Thus, the choice of the spiral heater, which will be guaranteed to be safe and effective - is not easy. However, it is not necessary to invest time on shopping trips and study of specialized information. Competent selection, proper wiring diagram - it all contributes to the fact that even in the bitter cold in your home will be warm, cozy and comfortable!
