Which heater is the most economical in terms of electricity: device rating

With the onset of cold weath­er, you want your apart­ment to be warm. But in the off-sea­son, bat­ter­ies are often bare­ly warm. An elec­tric heater can help warm the room. But the elec­tric­i­ty it needs to oper­ate is becom­ing more and more expen­sive every year. There­fore, before buy­ing, you should think about how ener­gy-effi­cient the new device is. We will fig­ure out how to find the most eco­nom­i­cal heater in the store.

Types of electric heaters

Before look­ing for the most ener­gy effi­cient heater, it is worth under­stand­ing how they work. There are four types of devices in stores. Let’s briefly char­ac­ter­ize each of them.

fan heater

In the case of such a device there is a heater in the form of a ceram­ic plate or a spi­ral and a fan. The cold air enter­ing inside quick­ly warms up and forcibly spreads through­out the room.

Fan heaters are com­pact and mobile, quick­ly warm up the room. At the same time, they make a lot of noise, burn out oxy­gen, raise dust and dry the air. Do not leave them unat­tend­ed, there is a risk of fire.

Oil radiator

In this device, the heat­ing ele­ment heats up the trans­former oil with which the body is filled. The device heats up, gives off heat to air cur­rents and emits infrared rays, which accu­mu­late in all near­by large objects. They, in turn, also begin to give off ther­mal radi­a­tion.

The advan­tages of oil­ers are con­sid­ered to be long-term heat trans­fer after turn­ing off the device, the absence of noise dur­ing oper­a­tion, the abil­i­ty to con­nect a ther­mo­stat. The main dis­ad­van­tages are the strong heat­ing of the case and the slow heat­ing of the equip­ment.

Convector

In his work, he uses the prin­ci­ple of nat­ur­al con­vec­tion. At the bot­tom of the device is a heat­ing ele­ment, which heats up the air flows that enter inside. The spe­cial shape of the body allows heat­ed jets to rise unhin­dered. Cold streams come from below in their place. Due to their change, con­vec­tive move­ment occurs, quick­ly rais­ing the tem­per­a­ture in the room.

The advan­tages of elec­tric con­vec­tors are silent oper­a­tion, high heat­ing rate, the abil­i­ty to install a ther­mo­stat, and a safe tem­per­a­ture of the case of a work­ing device. Cons — burn­ing out oxy­gen, dry­ing out the air, active dust trans­fer, rapid cool­ing.

infrared electric heater

The prin­ci­ple of oper­a­tion is sim­i­lar to the sun’s rays. IR devices are equipped with a gen­er­a­tor of infrared waves that are safe for humans. After turn­ing on the equip­ment, it emits waves that accu­mu­late in all large objects locat­ed next to it. They heat up and begin to give off ther­mal ener­gy, heat­ing the air around them. This is the safest and most effec­tive method. There are types of IR emit­ters. They can be car­bon, halo­gen, mikather­mic, quartz or ceram­ic.

The advan­tages of infrared devices with any type of heaters are com­mon. They do not burn out or dry the air, quick­ly and even­ly heat the room. They have one draw­back — the high price.

How to determine which heater is more economical

Elec­tri­cal appli­ances con­vert elec­tri­cal ener­gy into heat. And they do it in such a way that loss­es in the process are min­i­mal. How­ev­er, the effi­cien­cy of elec­tric heaters is dif­fer­ent. It depends on how the device works. The most ener­gy-con­sum­ing — fan heaters. They use the most elec­tric­i­ty. Oil cool­ers and elec­tric con­vec­tors are less expen­sive. The most ener­gy effi­cient infrared heaters.

These are gen­er­al val­ues, but there are some nuances that you should def­i­nite­ly get acquaint­ed with before choos­ing. So, for exam­ple, the oil pan heats up for a long time. All this time, it con­sumes elec­tric­i­ty, while the con­vec­tor starts to heat the room imme­di­ate­ly after switch­ing on. But at the same time, after the pow­er is turned off, the oil cool­er con­tin­ues to heat the room sta­bly, and the elec­tric con­vec­tor has to be turned on much more often.

The infrared heater is ener­gy effi­cient, but expen­sive. His acqui­si­tion will pay off soon. And if it is bought for a short peri­od of the off-sea­son, until the heat­ing is turned on, it will pay off even longer. Per­haps, in this case, an inex­pen­sive fan heater or elec­tric con­vec­tor will be the best solu­tion. It must be under­stood that heat­ing equip­ment of any type can be eco­nom­i­cal. You just need to choose the right one. We have pre­pared a list of char­ac­ter­is­tics that will tell you which heaters are the most eco­nom­i­cal and effi­cient.

  • The ratio between the heat­ing pow­er and the heat­ed area. The most impor­tant indi­ca­tor char­ac­ter­iz­ing the effi­cien­cy of equip­ment. If it is not spec­i­fied in the tech­ni­cal doc­u­men­ta­tion, it is easy to cal­cu­late it your­self. The first val­ue is divid­ed by the sec­ond. If the result­ing fig­ure is less than or equal to 100 W/sq. m, the heater is eco­nom­i­cal. Val­ues ​​from 150–200 W/sq. m say that elec­tric­i­ty is con­sumed inef­fi­cient­ly.
  • The pres­ence of a ther­mo­stat. It allows you to set the room tem­per­a­ture that the elec­tric heater will main­tain. The ele­ment mon­i­tors the heat­ing of the air in the room, and as soon as the tem­per­a­ture reach­es the set val­ues, the heater is turned off. When the tem­per­a­ture drops below the set point, the ther­mo­stat will turn on the heater. This allows you to main­tain a com­fort­able tem­per­a­ture regime and save resources. Devices with­out a ther­mo­stat, oth­er things being equal, con­sume more elec­tric­i­ty.
  • The pres­ence of a pow­er switch. Well, if it is pos­si­ble to choose one of two or three pow­er lev­els. So, depend­ing on the cir­cum­stances, you can choose the most eco­nom­i­cal mode. In any case, in order to choose an eco­nom­i­cal elec­tric heater for your home, you need to cor­rect­ly cal­cu­late the required pow­er. It is deter­mined based on the size of the heat­ed area, the height of the room, the num­ber of win­dows and doors, the lev­el of ther­mal insu­la­tion of the build­ing. It is bet­ter to entrust the cal­cu­la­tion to spe­cial­ists. A mis­take will lead to unnec­es­sary spend­ing on month­ly pay­ments for wast­ed elec­tric­i­ty.
