Winter cold evenings so nice to return to a cozy warm home! But sometimes the heating system can not cope with their duties, and then the electric heater becomes one of the most necessary appliances in the house. Manufacturers offer many models that differ from each other in power, work principles and appearance. In this case, all electric heaters must meet the following criteria: efficiency, safety, efficiency.
Many people are afraid of purchasing heaters, as they are afraid that electricity bills will increase significantly, but utility bills are so big. Perhaps once this was a problem, but not now, when there are economical energy-saving heaters.
Electric heaters, energy efficient, today is quite easy to find. Most manufacturers, including well-known brands, necessarily include similar devices in their product lines, and they invariably occupy top positions. Their main feature is the ability to convert electrical energy into heat.
Due to the variety of types of electric heaters, you can find an option that will be indispensable in the apartment, in the house or in the country. The most popular categories are:
- infrared heaters,
- oil radiators.
All of them are convenient in their own way, but the principle of heat generation is different for everyone. Also fan heaters, heat guns, electrofireplaces, heat curtains are in demand.

The most popular electric heaters
Oil radiators - the most common and familiar electrical heaters. Device consists of a sealed enclosurewhich looks like a regular battery of heating, inside which is filled with oil. When the radiator is turned on, the oil heats up, mixes and distributes heat over the entire area of the housing. Such a heater can be easily moved around the house, the only limitation is the length of the power cord from electricity.
In energy-saving radiators install a thermostat in order to protect against overheating and maintain the installed temperature (upon reaching this temperature, the thermostat turns off the heater and turns it on after cooling device). Another advantage of electric oil heaters - automatic shutdown when overturning. Therefore, it is not scary to leave it working for the night, besides electricity bills will not be frighteningly huge. By themselves, oil heaters are inexpensive, very well heat the house, but heat up slowly (up to 20 minutes), they can be installed only on the floor, the tightness of the case can be broken, then the oil can leak out.
Convectors, or heating panels, are great competitors to oil coolers. They heat the air around them and then spread it around the room using convection, in which warm air rises up, cold air descends and heats up, this cycle is continuously repeats. A thermostat is built into the energy-saving convectors, which allows you to maintain the desired temperature, and also protects the electric heater from overheating and burnout.
Convectors are made for every taste - you can choose the shape, size, even color, they may have different technical characteristics and price category. They are noiseless, usually have a nice appearance, a flat body, thanks to which they can be hung on the wall. Wall convectors consume much less electricity, than other types (for example, oil radiators), and some models work at gas or hot water. However, convectors dry the air, which is why many feel discomfort.
Infrared heaters transmit thermal energy through electromagnetic waves that the infrared emitter emits, thereby heating objects in the house, not air. This principle of heating is similar to solar and is completely safe for health. This is one of the most successful and economical options for heating your home. Of these, the most economic - carbonic. They are equipped with special lamps that consume little power and have a long service life. Among the shortcomings they note the limited effect of the device, since it heats objects only in the range of its radiation.
Fan heaters heat the room with a spiral element. They blow warm air and distribute it throughout the room. The disadvantage is a strong noise, due to which fan heaters are difficult to use for a long time. But at the same time, they have a high heating rate of the room and are therefore useful as an addition to the existing heating system (for example, if you need to heat the cottage very quickly). More sophisticated heaters of the latest models are equipped with a thermostat and an almost silent fan, so they can be used as an independent source of heat. After switching off the device, the room cools down quickly, so fan heaters, like heat guns, are best used in utility rooms or garages.
New in energy efficient heating appliances
A novelty in the field of energy-saving electric heaters - electric radiators. They are not as popular as the previous ones, but they have great chances to become popular. The electric radiator is able to heat up to 30 square meters in the shortest time. m, and the required temperature is accurate to a fraction of a degree integrated electronics. These devices are easy to install, have high fire safety.
Electric radiators are successfully used both in residential and commercial premises. Energy savings of up to 50% compared with conventional oil radiators and convectors. But due to the use of expensive materials and electronics in the manufacture of these devices, the cost of electric radiators is quite high, which makes them inaccessible for some buyers.
Another new electric heater for the consumer is the baseboard, based on the heating of the walls. It was designed specifically to reduce energy consumption with overall high efficiency. The walls heat up, form a kind of heat shield from the inside, preventing cold air from getting inside, and also radiate heat that spreads throughout the house. The plinth heater is characterized by fire safety, efficiency, is able to protect from dust, dirt, high humidity, but it does not dry the air. It is easy to install, and the service life is up to 20 years.
In order for the electric heater to serve for a long time and correctly, do not ignore the rules of operation. Firstly check the condition of the sockets. The basic principle: one outlet - one device. The power of the electric heater is too high, so if you plug another device into the socket, the wiring may not withstand the increased load and melt.
When choosing an electric heater for the home, pay attention to the following.
- The device must have a serial number - this will confirm the quality of the product.
- Ask the seller to show certificates of quality.
- If possible, check the reliability of the contacts - due to their circuit may cause a fire.
- Internal wires must be made of anti-inflammable material, then when the device ignites, they will burn no more than two minutes.
- Be sure to appreciate the quality of the heating element and plug. The plug must be grounded.
- Also make sure that the product is marked with the EU label - it will confirm European compliance with EU requirements, as well as safety for the health of consumers and the environment.
After purchasing an electric heater observe the following principles.
- Do not install a heater closer than 50 cm from any appliance.
- Do not place it in the window opening, as the curtains may catch fire.
- Do not leave the heater, not equipped with a thermostat, turned on at night.
- Do not use the appliance as a hanger or dryer - the heater may overheat and fail.
Be sure to follow the rules prescribed in the manual for the use and storage of the heater.
How to choose a heater
Which of the electric heaters fit exactly your home, only you can decide. The air heater heats up the fastest, convectors fit well into the interior, the cheapest oil radiators. But besides this, you need to take into account how often you use the room, how quickly and for a long time it is necessary to heat it, is there another source in it? heating... When there is no need to heat the air throughout the room, it is better to buy a heater with infrared radiation.
Determine what area you need to heat, given that to heat a square meter of space you need up to 100 watts of power. If you want to use the heater as an additional device, then a 800 thousand unit is enough. W. For ordinary apartments with ceilings of 2.5 m, the power of the device is calculated as 1 kW * 10 m3. For a room of 20-25 m3 An electric heater with a maximum power of 1.5 kW is required.
If you want to equip a bathroom with a heater, the infrared convector is the ideal choice, it is best suited for rooms where there is a lot of dust; an electric will perfectly fit into the room fireplace. But the children's room is well equipped with a wall or ceiling heater.
Don't forget that the miser pays twice. It is better to choose an expensive device than a cheap one - firstly, it will be made of better materials, therefore, there will be no unpleasant odors during operation, damage to the case, and secondly, it will be installed thermostat and overheat protection, resulting in reduced power consumption.
The best choice is the device that will create comfort in the house and at the same time save energy.
