It is winter now. This is the coldest season of the year and many people have a question of heating the dwelling. Many different heating systems are used for this purpose, but in today’s article we will focus our attention on how to choose such cozy home heaters, as electric convectors.
There is a lot of controversy about which heating systems are more beneficial and better – electric or gas. Each of these systems has its advantages and disadvantages. We will simply consider the properties of electric convectors – because they are considered one of the most economical and effective types of heating, especially for premises where there is no a gas supply.
What is a convector heater?
An electric portable convector heater is a household appliance designed to heat the premises with the use of electricity.
How does a convection heater work?
The main principle of operation of an electric convector is as follows: a warm air rises upwards and replaces by cold air as a result of heating from electric heating elements (the principle of air convection).
The main technical characteristics of the electric heaters are as follows:
1. Electric convector heater power.
The power of electric convectors is in the range from 500 to 3000 watts. This is roughly comparable to the power of irons.
The potential area of heating and, what is very important, the cost of heating depends on the power.
The required power of the convector-heater can be calculated approximately on the basis of the following ratio:
1 sq.m. of heating area = 100 watts of power.
Accordingly, a convector with a power of 1000 Watts can heat approximately 10 square meters.
How economical are home-based convector heaters?
In order to calculate the approximate cost of heating with an electric convector, its required power in Watts (kilowatts) multiplied by the time of use – so we will find out how much the convector consumes electricity in kilowatt-hours.
Then, this indicator in kW/h should be multiplied by the electricity tariff per 1 kW/h.
It is very good if the heater has a power regulation.
A regulation controller allows you to increase or decrease the power of the convector, depending on the user’s needs. Such economical electric convectors help reduce heating costs depending on the area size or temperature of outside air.
2. Method of placement.
Electric convectors can by such types by placement: floor, wall or universal.
- A floor electric convector heater is installed on the floor on special legs – stands.
- Wall mounted convectors are mounted on the walls using special brackets.
- A universal electric convector can be used both as a floor, and as a wall.
There are also built-in heaters, which are mounted on the floor of the room, but they are not very common.
To choose a room heat convector, like a gas range, you need to determine where you are going to put it first, and then select the model with the appropriate placement method.
3. Thermostat features.
A thermo-regulator (thermostat) is a device designed to regulate and maintain the heating temperature of the convector. Thanks to the special sensors, the thermostat helps to switch the appliance on and off depending on the set temperature of the heating.
Thermostats for electric convectors can be mechanical and electronic.
- A mechanical thermostat is more reliable and simple.
- An electronic thermostat is more functional, it allows you to more accurately regulate the temperature of the heating.
Personally, our opinion is that for cottages and districts with unstable power supply, it is possible to recommend models of convectors with a mechanical thermostat, in other cases it is possible to buy a convector with an electronic thermostat.
4. Safety issues.
Are convector heaters safe?
A household electric convector heater is an electric appliance of long time of use, so the safety features are very important for it. These basic characteristics include the protection against overheating and the class of electrical protection.
An electric convector overheating protection helps to turn off the appliance if it’s heating temperature reaches a critical value.
A class of electric protection indicates the degree of protection against electric shock.
Electric convection heaters should have at least II protection class with reliable insulation without the need of the device body grounding.
The parameters of the protection of an electric convector from dust and moisture can be attributed to the same characteristics.
The degree of dust/moisture protection is classified by the IP. For convectors this figure should be at the level of IP24, which helps protect the appliance from water spray and use it in very humid areas.
The above are the basic parameters of electric convection heaters, in addition to these main parameters, devices may have additional features in the form of programmable timer, LCD display and other.
For example, you can turn on/off heater with timer depending on your schedule of the day.
We wish you to buy the best electric convector heater and your house always will be warm and cozy.
