When choosing electric heaters raises the question about their efficiency - the cost of electricity per kilowatt of generated heat. Manufacturers, advertising their products, called the most efficient heaters of various types. Where is the truth?
efficiency heaters
The source of most of the heat is electric heaters TEN - tubular heater. It is a metal or a ceramic tube, inside which is located high resistance wire. Heater different from the conventional spiral and reliability in that the wire is not contacted with air or oxygen burns.
Efficiency of PETN as the helix is in the range 90 - 93%. This means that no matter how perfect the heating elements are not used, the savings in excess of 7 - 10% is not possible.
If the heating element is lit, both the infrared heater, some of the energy expended in luminescence efficiency and even less. Into the heating energy consumed in driving the impeller to rotate. From this it follows that the efficiency of heating devices of various types are about the same.
Ways to improve the heating efficiency
Notwithstanding the foregoing, the heating efficiency of heaters of different types varies. Manufacturers use a variety of ways to improve this parameter:
- oil Coolers - thanks to the considerable surface area in contact with it and is heated by a large quantity of air.
- Convectors, fan heaters - heat exchange with air is accelerated by increasing the air flow rate. The first method uses convection principle, in the second - the air flow generated by a fan.
- heaters, Infrared heaters - heating zone. Heat is directed to the place where it is needed.
- Automation - disable thermostats allow heating devices upon reaching a predetermined temperature, timers - turn on and off at a predetermined time.
Thus, the heating efficiency can be enhance by applying the most effective types of heaters for specific conditions. oil coolers suitable for continuous heating.
If you need to quickly raise the temperature in the room, you should buy the convector, even better - heater. If you want to zone heating, choose a heater or an infrared heater.
