As soon as autumn begins to speak openly about their rights in unheated apartments gets cold, especially at night.So people rush to the store for heaters designed to carry into the house of welcome warmth and comfort.To make it easier to choose, we offer a series of articles such as review of the different types of devices.So, before your eyes is the first article in this series.She devoted so popular at the moment oil heater.

Today we look at the principle of operation and design features electric heater oil type.Also, talk about how to choose the oil heater for domestic needs, what should be paid at the same time the most attention, and which moments of absolutely no importance.You will also learn how to unpleasant consequences may cause improper operation of the device, and how to escape safely.

design oil heater

most important part of the oil heater type is naturally cooler.The material of manufacture - ferrous metal, and the thickness - of 0.8 to 1 millimeter.Since the dimensions of all elements of the product must be very precise, it is used for the manufacture of laser cutting of metal, leaving behind a straight edge and a smooth surface.To create angles used sheet bending equipment, and the smallest details of the stamp.

Each section of the radiator should be sealed, so the details of which it is composed, are welded together (by spot welding) and pressed.Before this, they are performed openings, allowing the radiator to collect from the individual sections using the plug-in connection, characterized impermeability and reliability.The paint is applied to the heat sink is very strong - in fact it is applied by powder technology, and is polymerized by heating in a special oven.

When the radiator is fully assembled, it is filled transformer oil mineral type.In older models, for that there was a special valve, now the oil filling is carried out directly during the assembly of the heater.This device is installed inside the electric observing leaks and outside - panels made of plastic and metal, equipped with a thermostat, power control and protection device against overheating.Also at this time the power cord is attached.

castors for ease of use are attached to the bracket nuts already after the oil heater has won a permanent place in the room.

principle of operation of the oil heater type

turned on the heater in the network, you should first install the regulator desired temperature in the room.In this first heating element is heated (electric teplonagrevatel), and then the heat is transferred from a mineral oil.Then everything is simple: the hot oil radiator heats the body, and he, in turn, gives heat to the air of the apartment.The most that can happen to heating of the metal casing - 150 degrees.However, different models of various heaters that threshold - it may be lower, but above this temperature.

Process heating radiator

Do not believe the advertising ploy by the seller, who admiringly tell that oil heater can produce heat, like a fireplace.This, in principle, can not be - after all, according to the laws of physics, the warm air rises.So occurs convection.If we talk about the beam thermal radiation, it heats only the fins, the sections which are located opposite each other.

Choosing an oil heater in the parameters


First of all, pay attention to the power.From it depends what the area will be warm.Thus, at 15 square meters requires a heater with a capacity of not less than 1.5 kilowatts.This meant that the street winter and hard frost.However, for a long time at this mode, the instrument will not last - he will have to operate at maximum power.Therefore, heating the same 15 square meters still need a heater for 2 kilowatts.At the peak it will work only in the coldest days, and during the cooler - at half the power.If the room you plan to heat, a little, then do not buy heavy-duty models.So the device will continue to cool, and the air in the room will not meet the standards.

thickness radiator sections

second important parameter - the thickness of the section of the radiator.The narrow section and heated quickly, and electricity "eat" a little, but that's their total area is too small.So they heated air is not very fast.As for the wide sections, they will, too, quickly cool the air, so the savings of electricity there can be no question.What is a higher priority - fast heating facilities or savings - you decide.

mode switch power

When buying a device, be sure to check whether he has the power mode switch, adjustable thermostat and overheat protection.And also desirable to have such features as Auto power heating.

The air after prolonged use of any heater becomes extremely dry.Therefore, thinking about how to choose an oil heater for the apartment, it makes sense to stay on the models, which have a special container made of metal to evaporate the water.If desired, it can be easily removed.

internal fan

There is one way to quickly warm the air in the room.To this end, close to the oil heaters pose a fan, turning it on low power.In this heat quickly spread to all corners of the room.Some fan heaters already have - it is built, and it is very convenient as it is not necessary to attach additional devices.He pressed a button on the heater housing - and you're done, the air in the room warms up in no time.Therefore, when deciding which oil cooler better, give preference to models having a built-in fan.

Look at the security model

for children's rooms, for example, manufacturers offer heaters with a casing, which does not allow the child to get burned.Unfortunately, this hinders the process of enclosure movement of heated air, otherwise, convection.

It looks like a radiator guard.

Instrument weight

By choice the oil cooler, try it out on weight - is also important.And some manufacturers save material, and an impressive-looking device would be quite easy.Do not take this model.Then one of two things: either the heat sink is made of very thin metal, or oil is poured into it a little.And then, and another is not very good.

Weight Radiator

Do not fall for the bait cunning sales consultants

  • If you are told that the heater is a model does not dry the air, do not believe - any device that uses convection to air dry.
  • All oil heaters do not burn dust (their contact with the heating element is not room air), so that this property can not be a plus certain models.
  • If the seller claims that only "the heater" does not rustle up, allow yourself to doubt it.After convection causes the air, and with him and the dust moves, especially stagnant.
  • If you are told that the dark oil heater warms better than the light, it is again a lie.Most likely, the sellers have to sell the unsold goods.Think about it: for in the radiator heat is not sunlight (in this case, really dark surfaces are heated more strongly than light), and a very different way.
  • Do not believe the existence of the mythical wall heaters such as oil - they do not exist.To avoid overheating the device, put it on the wall two feet, not closer.

errors when usingOil heaters and their implications

error 1. In wet areas, such as in the bathroom, heater type of oil to use is extremely dangerous - can strike shock.

error 2. Do not touch the working device bare hand (of course, if he is not provided with housing) - burn.

error 3. From the walls of the heater does not place any closer than half a meter, or thermal relay will continuously switch off the device.Also, it does not cover the radiator with a cloth or other materials, to dry wet clothes on it.Things can be dried on a removable rack, which is located at some distance from the radiator.

error 4. Lying on his side, included oil heater starts to be dangerous.Hot oil can break the radiator and cause a fire.After all, it is not poured to the top, and in the lateral drains with PETN, which is exposed, is heated to 800 degrees.Result - a break radiator and unpredictable consequences.Hot oil can cause serious injury to anyone who happens to be close to this point.

error 5. If overheating sensor is faulty, the heater network will never turn on - it will also be dangerous.Indeed, in this case, the instrument will cease to be switched off, soaking indefinitely.As a result, there is again likely broken and the metal housing of the fire.

Error 6. If you decide to keep winter oil heater in unheated rooms, such as a garage, you can say goodbye to him forever - body radiator damaged and oil spilled.

error 7. Never red tape device across the room for the power cord - it is fraught with wire breakage or short circuit.

So, how to choose the right oil heater, we have told you.Of other types of radiators, read the following review.
