Need of purchase of the electric heater is caused by lack of heat connected with interruptions of work of the centralized heating. Emergencies, shutdowns or just low temperature of the radiators established in the house are frequent. Besides, there are cases when long-distance heating in general is absent. That in your house it was always warm, cozy and comfortable, it is necessary to establish additional source of heat.
For installation in the apartment, owner-occupied dwelling or at the dacha the autonomous sources of heat working from current network are often used. Electric heaters which are offered by the industry happen several types: fan heaters reflectors, oil batteries radiators, convectors and infrared heaters. All of them are available at the price, are safe in work, are easy-to-work, but not all are equally demanded. Reflectors differ in high efficiency, but very much dry air, infrared have appeared recently and are still a little known to consumers. Oil heaters and electric convectors are in the greatest demand. To make the necessary choice, it is necessary to learn about merits and demerits of each of these two types of heaters.
Oil electric heaters
Represent the radiators established on the wheels facilitating their movement. Can be put to any place where length of electric cord allows. That it has begun work, it is enough to pull out of it from packing and to include in the socket. Such device is the hollow metal body which area is increased at the expense of ridge surface. In it there is special rock oil and heating coil – Teng. At inclusion, oil gradually heats up, and then temperature set by means of temperature regulator is only maintained in the device. Oil has low heat conductivity therefore well holds the gained temperature.
Initially, it were quite simple devices equipped only with protection against overheating and which are switched-off at achievement of certain temperature. New generations of oil heaters have the built-in temperature regulators allowing to establish the necessary value of temperature; timers which set time of inclusion and shutdown of the device; the sensors of horizontal position which are switching off radiator in case of capsizing. Some models are supplied with fans, significantly accelerating process of heating of rooms. Besides, modern radiators have also the drip-proof execution excluding hit of oil on surrounding objects in case of microcracks and the output of the device out of operation.
Damage of the body at long life cycle belongs to some of shortcomings of oil electric heaters, but it is compensated by such advantages as ease in operation, mobility, silent work and acceptable cost.
The greatest possible value of temperature up to which the device heats up, set within 70 wasps it is connected with safety of operation and excludes burns at touch, and, besides, at this temperature oxygen is not burned and surrounding air does not dry, the smallest parts of dust do not burn, there are no specific smells.
Both for oil, and for convector heaters ruled fairly: 1 kW of power on each 10 sq.m of the space of room which needs to be heated.
Electric heaters of convector type
The design of the heater of convector type is quite simple - it is the flat metal body with openings in the lower and upper part in which heating coils are located. The way of fastening can be both floor, and wall. Both wheels, and the devices allowing to install the convector on wall under window are included in the packages of many such devices. The principle of work is based on natural convection – circulation of warm air mass. Coming to the lower openings, air heats up, rises to ceiling up and, in process of cooling, falls down again. Such continuously circulating air streams are capable to warm up the room quickly enough and evenly. Usually, the maximum temperature of heating is limited 60 wasps that guarantees safety to children and pets.
Opportunity to program operating modes allows to cut significantly electric power consumption the heater of convector type.
Temperature of warming up is controlled by the built-in thermostat which switches on and off the device in process of achievement of the established value. These are the safe devices which are working silently and not worsening air quality in the heated room. As heating coils do not fasten directly to the metal body of the convector, there is no need to ground them, the device can be turned on in the normal household socket. Installation of several convectors in rooms and other rooms of the country house allows to receive autonomous heating services which will be rather economic as will work only from time to time and for it it is not necessary to lay the system of communications and to buy heating boiler.
What to choose
Judging by numerous responses of users which can be esteemed at forums on the Internet, both of these types of heaters find the supporters. It is necessary to choose taking into account the requirements and conditions of their use and installation. If fast and effective heating is necessary for you, install the convector or the oil heater with the fan. But it is necessary to consider that convectors are safer, have the esthetic design fitting into any interior and have bigger life cycle – up to 10-15 years.
