How to choose a fan heater
During the period of changing seasons with the arrival of cold weather, many people think about which electric heater to stock up on for the winter. Stationary heating in an apartment that functions reliably or a powerful autonomous boiler in a house is a guarantee of warmth and comfortable living in a dwelling. Well, if the temperature in the living room is maintained at +20? up to +22 ?, and the walls and windows of houses have sufficient frost resistance. At this temperature, an optimal microclimate is created for people to live. If you want to save on gas consumption by the boiler, then you can take care of an alternative source of heat. For these purposes, fan heaters are often used. This article will discuss how to choose a fan heater and what is important to consider.
It is known that many central heating networks of buildings have long since developed their resource, some literally, and some hold on to their word of honor. And heat supply organizations-operators are not able to provide additional heat supply to freezing consumers during periods of cold weather. Therefore, rely on the help of public utilities is not particularly necessary.
How not to freeze and save?
With a sharp decrease in temperature in winter, it is easier for owners of individual heating to get out of the situation than for apartment residents who depend on heat supply organizations-operators. Yes, and the owners of private houses know how expensive the venture of additional heating of the whole cubature of the house during periods when there is a bitter cold outside the window. Typical everyday experience: the consumer raised the temperature of the air in the house by an additional 2? –4? and got the consumption of energy on the meter 1.5 times more. Forced heated rooms in the house, which are rarely used. Have to warm up to 20? space of walk-through rooms, corridors, wall and stairways. And, without that, the main article of the communal expenses of the winter period is the payment for heat, private consumers are threatening to fly a pretty penny.
The way out, for those living with centralized heating, is to purchase electrical sources of additional heating for the apartment. For those who have installed adjustable heating systems, you can purchase mobile sources of local heating for the house. Place them in a residential area (hall, bedroom, children's room), at the same time, lowering the temperature of the batteries of the centralized heating system to "economy" level.
Allowed to reduce the temperature in the room to +6? - This is the so-called non-freezing temperature level of the heating system, at which it will not fail.
Types and types of devices
The most common among electric heaters are models of fan heaters.
Fan heater is a type of climatic equipment for heating the air flow, by passing an air jet through the heating element.
Devices with power up to 2 kW belong to the household group. With a capacity of more than 2 kW, are classified as industrial, and are called heat guns. When choosing the rated power of the fan heater, you should follow the simple rule: is 0.1 kW of heating element power enough to warm up 1 m? the floor space of the standard ceiling height, ranging from 2.4 to 3.1 m.
By installation and installation features, fan heaters are divided into types:
- Desktop portable.
- Floor speakers.
- Wall and ceiling suspended.
Structurally, the fan heater consists of parts: a case, a heating element and a fan.
Housing
Which is better to choose the body? The case of a heat vent type heater must be made of durable heat resistant plastic. Special attention should be paid to the level of dust and moisture protection of the fan heater casing according to the international two-digit scale IP. Thus, compliance with the IP24 level, most often indicated in the product specifications, means:
- Index "2" - protection against the contacts of human fingers and penetration into the device of objects larger than 12 mm. This allows you to safely use the device in children's rooms.
- Index "4" - protection from continuous splashing or pouring water from all directions. This means that such a fan heater can be used in the bathroom and shower rooms, pool areas.
The electrical safety of the device must correspond to a higher or higher (1 or 2) category.
The housing of a domestic fan heater is additionally equipped with a thermostat with a temperature regulator on 3 positions, a turning mechanism, an exit louvre grille and a built-in humidifier.
Type of heating element
What type of heating element to choose? 3 types are applied:
- Spiral open type is made of nichrome wire, t heat.= 1000? C.
- Tubular (TEH), graphite or metal rod in a glass capsule, t heat.= 500? C.
- Ceramic element, which is a spiral pressed into a ceramic bar or plate, t heat.= 150? C.
The most common and passed the test of time are heating elements of the type of heating elements. Give preference to fireproof structures with a ceramic heating element.
Fan
The fans used in the designs are of two types:
- Axial (axial) with traditional blades like "propeller".
- Tangential in the form of an elongated cylinder - “squirrel wheel” with side air intake blades.
The most common and less expensive are axial fans. Tangential less noisy, but have large dimensions, so they are used in column designs of fan-type heaters.
So, given the basic characteristics of fan heaters, you can choose the device that will best meet the requirements for operation. If you have questions on the topic, then write a comment on the article. Maybe you have already purchased a fan heater? Then share with us your observations.
