How to quickly heat a room?
So, on the long-awaited winter weekend, you came to the dacha to spend time in comfort. If you have taken care of the heating on duty, the house will be cool, but without a feeling of dampness - convectors dry the air well. There are several ways to quickly heat a room. The so-called high-power heat guns - electric or gas - are especially effective; they can warm up the air in a room in a matter of minutes. This is the best option for heating the house to a comfortable temperature, but it will not help maintain the conditions created in the premises for a long time. If you want to stay overnight in a country house, you should light a fireplace or brick oven. It will take a long time to warm up, but will also be able to maintain a comfortable temperature in the room for a long time.
Electric convector - calculation of kW consumption.
Agree, buying an electric convector is one thing, but how much we will have to pay for the heat received is quite another, that is the question. We emphasize that our calculation of consumption is based on personal operating experience, and not on manufacturers’ formulas. Let us also make it clear that we do not heat the house in the frosty winter, we raise the temperature in the room to a comfortable state. Let's consider an average room of 18 m2. The technical characteristics of any manufacturer for heating a room of such area regulate the purchase of a 1000 W convector.
Let us clarify that to start central heating, municipal authorities are guided by the Decree of the Government of the Russian Federation dated May 6, 2011 N 354, according to which the street temperature must drop below +8 ºС and not rise for 5 days. I think many will agree that usually, in the off-season, it can take a month to achieve this goal, and the temperature outside the window is + 12°C, already reducing the temperature in city apartments to + 16 – 17°C.
Consumption calculation
We plug in the electric convector and set it to a comfortable 22 °C. We will not go into calculations; everything has been tested many times experimentally. With the door closed and the window closed, in full power mode at +17 °C. up to +22 °C. , a 1000 W convector runs for about 25 minutes. You can always double-check this and write your result in the comments.
When the set value is reached, the temperature control system will work and the consumption of electrical energy will stop. As it cools down, noticeably after 20 minutes the temperature sensor is triggered and turns the convector back on. Considering that the next switching on does not require heating from 17 °C, but starts from 20 °C, then the time to reach the value is 22 °C. much less, no more than 10 minutes. Then the on/off cycle is repeated and the average heater operation does not exceed 20 minutes per hour.
Actually, based on the experimentally obtained data, we obtain the consumption of an electric convector. Divide 1000 W by 60 minutes and get 16 W - we determined the electricity consumption of one minute of operation. In our experiment, the convector worked for no more than 20 minutes. Now we multiply 16 W by 20 minutes and get the power that the convector consumed per hour of operation - 330 W. Thus, the convector “eats” 1 kW in three hours. The cost of one kilowatt at the beginning of 2021 is 4 rubles.
Gentlemen, per evening we will need no more than 9 hours of operation of an electric convector - 12 rubles. A month in the off-season will cost about 360 rubles. To be on the safe side, let’s add another 30% to this amount (for those who sit too long in front of the TV). The total cost of operating the convector will be 400 – 500 rubles for normal temperature conditions for a month. Let me ask you a question: is it worth saving this amount, exposing your body and your household to the risk of cooling? Sick leave and a bad mood are much more expensive; drops for a runny nose alone can offset this kind of savings.
Selecting the type of heater
The oil heater is convenient and practical to use and has several operating modes. Heating a cold room occurs rather slowly, but in economy mode the device successfully maintains the temperature from a heated stove and can heat a small room well all night.
An electric convector heats a room by circulating warm air passing through thin heating elements. An adjustable thermostat automatically maintains the set temperature. Convectors heat the room faster, but cool down quickly after switching off.
Fan heaters heat the air in a cold country house even faster. They should not be used for a long time, as they burn oxygen and dry out the air.
Modern infrared heaters are gaining popularity due to their ease of use and cost-effectiveness. They heat objects located within the reach of the rays, but it is not recommended to stay directly under such a panel for a long time. It is better to install such a device near the door or away from the bed and dining table.
Fan heaters
The main advantage of fan heaters is their compactness and the ability to quickly heat the room. An electric fan heater consists of a heating element and a fan.
Important! Fan heaters, depending on the power of the model, can be used to heat both residential premises and large industrial facilities of a large area, for example, warehouses or hangars.
Household fan heaters are easy to use and compact. Their cost and quality depend on the type of installed heating element, which is used:
- spiral;
- heating element;
- ceramic type heater.

The main disadvantages of spiral fan heaters are also the increased consumption of electricity and the high heating temperature of the spiral - when dust gets on the spiral, it burns, emitting an unpleasant and harmful odor to humans.
Important! Ignition of dust accumulation can cause a fire, so it is necessary to turn on the unit with visual control of the start of work.
The fan heater must be installed out of the reach of children; the device must not be left turned on unattended or children should be allowed to control its operation.
New types of heating element fan heaters are equipped with a heating element made of wire or graphite. They are safer to use than their spiral counterparts, but are more expensive.
The most advanced fan heaters are ceramic models, equipped with heating elements coated with a layer of porous ceramics. The ceramic coating is a kind of heat insulator that reduces the surface temperature of the heater, making it safer. However, this effective design feature also results in a higher price for such devices.
