Which heater is better to choose: oil radiators, convectors, heat fans, infrared quartz heaters.
In cold winters, often there is not enough heat that gives us central heating or a stove. And country houses, in which heating is not provided, are often visited in the winter. To create comfortable conditions in a cool room and in an unheated cottage, heaters will help.

How to choose a heater
Heaters can conditionally be divided into four groups: oil radiators, convectors, fan heaters, infrared emitters.
To choose the right heater for specific conditions, you need to consult with specialists, they will help to calculate the required heater power.
And then, as in a joke - I went to buy a bag, and bought a pocket heater.
If no one can give advice, do the calculations yourself.
For example, for heating an unheated room with good thermal insulation, with a ceiling height of 2.7 meters, about 1 kW is needed. on 10 square meters.
For a living room in a house with central heating, an electric heater with a power of 1-1.5 kW is enough. on a living room up to 20 square meters.
Oil coolers
These radiators are most suitable for heating apartments and residential buildings.
In appearance, these are batteries filled with oil.
The oil, when heated, transfers heat to the metal surface of the radiator.
Oil radiators differ in the number of sections, the smaller the sections, the smaller the surface area of \u200b\u200bthe radiator, the more it will heat up.
On the contrary, the more sections it has, at the same power, the lower the temperature of the radiator walls.
On sale you can find oil radiators with a capacity of 250 watts or more. up to 2.5 kW.
Oil radiators work only in an upright position; it is forbidden to tilt or turn them over.
After buying and transporting, before turning on, the radiator must be kept upright for several minutes.
In no case can the radiator be used as a clothes dryer, this will lead to overheating or even a fire.
Although some models are equipped with special heated towel rails.
Modern radiators can be equipped with a humidifier (a small capacity where water is added as needed), a fan, and also a protective casing, it hides the radiator fins and gives a more stylish look.
At the same time, the casing increases traction and the speed of distribution of warm air, thereby accelerating the heating of the room.
In operation, oil radiators are silent, retain heat for a long time after being disconnected from the mains, and easily move on wheels.
Some models do not require disconnection from the mains, as they are equipped with a thermostat and a timer.
limitations
The room is heated for a relatively long time, the danger of burns, since the surface is very hot.
Due to fire safety, the radiator should be located at a distance of 50 cm from the wall and fusible surfaces.
Convectors
These are compact, flat or flattened devices, they are placed on the floor or mounted on a wall, best under a window.
The lower the device, the more efficient it is. Convectors are produced with power from 250 watts to 5 kW. Depending on the heat carrier, convectors are gas, electric or water.
Gas are used where there is no electricity.
These models can be connected to both bottled and main gas.
During the operation of devices, the smell of gas is not felt.
Electric convectors are mounted on the wall or mounted on the floor.
Water convectors, outwardly similar to electric, they serve as an element of a water heating system. Water convectors are baseboards (used to heat the air in the bathroom, on the balcony, i.e. in those rooms where it is not convenient to install conventional heaters).
In operation, these heaters are silent, fireproof, externally beautiful.
If several convectors are combined and equipped with a special control unit, then this system is suitable for greenhouses and winter gardens.
limitations
Heaters of this type, without a built-in fan, cannot quickly heat a cold room, but they are suitable for maintaining the required temperature in the house.
Heat fans
The most simple and affordable appliances for heating.
Used to quickly warm small rooms.
A heating element is inserted in them - this is a thin metal spiral, a heater, or a ceramic heating element.

A fan heater with a ceramic element does not burn dust and does not pollute the air with combustion products. Modern models are equipped with built-in filters, a humidifier and a timer.
Wall and floor models are produced, in the event of a fall, most of them automatically turn off.
On sale heaters with power from 600 watts to 3 kW.
heat guns
High-power heat fans (from 3 to 30 kW.) Are called heat guns.
Such fan heaters quickly heat the room, have protection against overheating, automatically turn off in the event of a fall.
Most modern models have a thermostat and special protection against accidental ingress of water.
limitations
Noise at work, unpleasant odor from dust burning on a heating element, a red-hot spiral burns out air, can cause a headache.
Infrared Quartz Heaters
Unlike other heaters, infrared heaters do not heat the air, but the surfaces of objects that are aimed at.
With the help of such heaters, it is possible to create zones with local heating, this allows you to save electricity, allows you to create a microclimate for individuals.
Infrared heater can be floor, wall and even ceiling.
Long-wave infrared heaters have a heating element - TEN, this metal plate heats up to 230 degrees.
They are installed so that from the surface of the device to the heated objects there is a minimum of 50 cm.
For short-wave infrared heaters, the spiral is in a glass tube and heats up to 600 degrees, they are installed no closer than 3 meters.
These devices have power from 300 watts to 4.2 kW.
There are models with a rotary reflector, but for safety reasons, a person should be at a certain distance from the device.
In operation, these devices are silent, installation in wet rooms is allowed.
limitations
It can not be placed close to a person and sent to a fusible surface.
