Oil electric heaters
are radiators mounted on wheels that make them easier to move. Can be supplied to any place where the length of the electric cord allows. To get it started, it’s enough to pull it out of the pack and turn it into the outlet. Such an instrument is a hollow metal body whose area is increased due to the ribbed surface. Inside it there is a special mineral oil and heating element — tenn. When switched on, the oil is gradually heated, and then the device only maintains the temperature set with the help of the thermoregulator. Oil has low thermal conductivity, so it keeps the temperature high well.
Initially, these were quite simple devices equipped with only overheating protection and disconnecting when a certain temperature is reached. New generations of oil heaters have built-in thermoregulators, allowing you to set the desired temperature value; timers that set the timing of the device on and off; sensors horizontal position, turning off the radiator in case of rollover. Some models are equipped with fans that significantly speed up the heating process. In addition, modern radiators have also a splashproof design that eliminates oil from the surrounding objects, in case of microcracks and failure of the device.
Damage to the hull during long service life is one of the disadvantages of oil electric heaters, but it is compensated by such advantages as ease of operation, mobility, $ silent work and acceptable cost.
The maximum possible temperature to which the device is heated is set within 70oC, this is related to the safety of operation and eliminates burns when touched, and in addition, when this temperature does not burn oxygen and does not dry the surrounding air, do not burn the smallest particles of dust, there are no specific odors.
For both oil and convector heaters, the rule is true: 1 kW of power for every 10 square meters of space to be heated.
Convector type electric heaters The design of
the convex heater is quite simple — it is a flat metal housing with holes in the bottom and top, inside which the heating elements are located. The method of attachment can be either floor or wall mounted. The sets of many such appliances include both wheels and devices that allow the convector to be installed on the wall, under the window. The principle of operation is based on natural convection — the circulation of warm air mass. Entering the lower openings, the air heats up, rises up to the ceiling and, as it cools down again. Such continuously circulating air flows can warm up the room quickly and evenly. Usually, the maximum heating temperature is limited to 60°C, which guarantees safety for children and pets.
The ability to program modes of operation allows to significantly reduce electricity consumption by a convector type heater.
The warming temperature is controlled by an integrated thermostat, which turns the instrument on and off as it reaches the set value. These are safe devices that operate silently and do not impair air quality in a heated room. Since the heating elements are not attached directly to the metal convector housing, there is no need to ground them, the device can be incorporated into a conventional household outlet. Installation of several convectors in rooms and other rooms of the country house allows you to get an autonomous heating system, which will be quite economical because it will work only time from time and it is not necessary to lay the communications system and buy a heating boiler.
What to choose
Judging by the many user reviews that can be read on forums on the Internet, both of these types of heaters find their supporters. Choose according to your needs and conditions of use and installation. If you need fast and efficient heating, install a convector or oil radiator with a fan. But it should be taken into account that convectors are safer, have an aesthetic design that fits into any interior, and have a longer lifespan — up to 10-15 years.
