Oil radiator test. It all depends on how well you choose the oil radiator. Test method: Sergey Lippart

Centralized heating in Russia does not always satisfy the needs of residents. This is due not only to insufficient temperature of the carrier, but also to the low quality of the lines. Because of this, people in the winter have to look For example, most people disconnect from center line and installs autonomous heating. However, not everyone can afford it. If you need to heat a room and at the same time save your budget, you can purchase an oil radiator. Reviews about such heaters are not always clear.

Why is an oil cooler good?

Naturally, everyone wants to get a good and relatively inexpensive heat source. For some, the small dimensions of the product are important, for others, the cost of the heater is important. In any case, the oil radiator, reviews of which we will consider in this article, meets all the requirements for it. This is an economical and safe product, and at the same time very effective.

The difference between such a heater and a classic one is that oil is used as a coolant. The spiral heats a special liquid, which has a high heat transfer coefficient, after which the metal body of the product is heated. Some models have a fan that circulates hot air, spreading it around the room. It is worth noting that today there are a huge number of products on the market. Each product has its own design, different power and functionality. All this plays a big role, but first let's deal with the most important thing.

What consumers say about the advantages of oil heaters

As noted above, there are currently a huge number of models. Consumers say that the quality of a product largely depends on the manufacturer. If you buy a cheap Chinese model, you usually shouldn’t count on high quality heaters. At the same time, European oil radiators, reviews of which are mostly positive, are distinguished not only by their high quality, but also by their attractive design with a wide range of additional functions.

However, consumer feedback doesn't end there. Many people say that it is extremely important to correctly calculate the power of the device. In most cases it is recommended to take 10 square meters 1 kW. Accordingly, if you are going to heat a room of 20 square meters, you will need a 2 kW heater. Consumers note that if the building is insufficiently insulated, a power of 1 kW per 10 sq.m may not be enough. Therefore, it is always better to buy with a reserve. Now let's look at the principle of operation of the device.

Details about the design

Currently, all manufacturers make the case, that is, the radiator, from ferrous metal with a high zinc content. The presence of this element completely eliminates the possibility of corrosion, at least in the next few years of operation. The working element is manufactured at laser machine, smaller parts are stamped. Then the product goes spot welding, coloring and polymerization.

After this, mineral oil is poured into the radiator, a heating element is installed and the cable is connected. A thermostat switch, as well as an adjustable thermostat, must be provided. Please ensure that the heater is equipped with a water container. This is due to the fact that during operation the air dries out, and to solve this problem, place a container with water, which evaporates during operation of the unit. This is exactly what an electric oil radiator should be like. Consumer reviews indicate that models installed in a children's room must have a special casing that will protect the child from being burned by the body.

Electrolux oil radiator: consumer reviews

Heaters from this manufacturer are very popular. This is due to several factors. Firstly, this is a well-established company from Sweden. The build quality here is excellent, just like the durability of the product. Despite the fact that the manufacturer provides a 1-2 year warranty, users say that Electrolux oil radiators last 5 years or more during normal use.

The product body is made of stainless steel, which makes it resistant to mechanical damage. In addition, almost all models are equipped with rollover protection. This means that if the unit accidentally turns over, the protection will work and the device will turn off. There are several other significant advantages, because of which an Electrolux oil radiator is actively purchased. Reviews indicate that the company's employees have worked hard to improve security. Here you will find a shutdown sensor, tip-over protection, a reinforced sealed housing, etc. It all has great importance, especially if the device operates around the clock.

Brief review of Electrolux EOH/M-3157

This oil heater is considered one of the best. Firstly, it was developed quite recently, and includes all the latest solutions from engineers. The body is made of stainless steel, and a special apron protects the cylinder. This makes the device not only safer, but also more attractive from a design point of view. In addition, this model is also notable for the fact that the supports have a somewhat non-standard placement, which gives the radiator increased stability. The kit also includes a pair of removable casters for more comfortable movement of the heater. Electrolux EOH/M-3157 has a power regulator: minimum 600 and maximum 1,500 watts. The stated service life is 10 years, and the warranty is 1 year. We can say that the Electrolux oil radiator has extremely positive reviews, so experts recommend confidently purchasing this device for a room of no more than 15 square meters.

Heaters from this manufacturer are the golden mean for many. The fact is that Ballu units are considered to be of quite high quality, although there are flaws in the design, but the cost of such devices is usually low. Many consumers say that for only 2-2.5 thousand rubles you can buy a 9-section 2 kW heater. Experts, despite all the shortcomings of the product, recommend it to those who want to save on heating and not freeze. The fact is that the company uses an innovative coating that increases the total heat transfer by 20%. This means that you can save a lot by purchasing a Ballu oil radiator. Consumer reviews indicate that the effectiveness of this coating is somewhat lower than stated, however, “Ballu” is popular among users.

What they say about the Polaris technology

Despite the fact that this heater is from China, it is very popular among Russian consumers. There is a completely logical explanation for this. Firstly, the low price of the product, and secondly, a fairly high-quality assembly. But it is worth noting that consumers are advised to check the product passport, otherwise you can easily run into a fake. The main disadvantage is the lack of a water tank, although expensive models imply the presence of one. If you want to save a lot and not go wrong, then choose a Polaris oil cooler. The reviews are generally positive and say that you can dry things on a heater of this type. Almost all models have an attractive spring appearance.

About Thermia radiators

Heating appliances from Ukraine are of average quality and price. This makes them quite popular, since they rarely break down, and the service is more or less adequate in most cases. There are several significant advantages that make it worth buying Thermia oil radiators.

The onset of cold weather is inevitable, and many feel chilly at the mere thought of how central heating works, and anxious at the memory that it is cold in the “leeward” rooms, despite the insulated windows. And then this category of our fellow citizens has the happy idea of ​​purchasing an oil heater.

Test method: Sergey LIPPART

WHAT TO CHOOSE?

The question of choice is not an easy one. We sincerely hope that the test will help you find “your” heater. We booked the event in accredited testing laboratory TESTBET.

The selected devices belong to the same class, have the same rated power -2000 W (with the exception of PO-1123 from Aeronik, 2300 W), are similar in appearance, but behave differently when tested. The more interesting it is to get to know each other!

WE STUDY TECHNICAL DATA

1. Heating elements

The presented models have three heating stages:

• Maximum - two heating elements are turned on,
• medium - heating element for 1200 W,
• minimum - heating element for 800 W.

Aeronik has corresponding elements that are a little more powerful.

2. Frost protection

An original function meaning that the device can maintain a temperature of about 5? C. This is true for dachas: turn on the heater and leave it (if you simply leave the heater in an unheated house for the winter, the oil in it will thicken). For three models this option is indicated in the instructions, but for the rest you can set the minimum temperature manually.

3. Number of radiator sections

The number of fins directly depends on the power: the greater the power of the radiator, the more fins are needed to dissipate it. Heaters with a power of 2000 W are in greatest demand, as this is the optimal power for city apartments, allowing you to heat a room of 20 sq.m. Typically, heaters of this power have 9 sections. The heater presented by De’Longhi has eight sections, but has an external casing that promotes convective draft. And Aeronik provided a device with 11 sections, since it has higher power.

4. Timer, clock, remote control

A nice feature of the De’Longhi TRD0820ER and Vitek VT-1729 BK devices is the possibility of delayed start (De’Longhi can also be turned off) thanks to the presence of a timer. You leave for work, set your expected return time, and a comfortable temperature is guaranteed upon your arrival. De’Longhi TRD0820ER also has a remote control that allows you to adjust the room temperature without leaving the sofa.

WE MEASURE TECHNICAL PARAMETERS

This stage of the test was carried out at a network voltage of 220 V.

1. Power

Measuring the actual power consumption at a voltage of 220 V revealed a deviation from the nominal one declared by the manufacturer. The minimum difference in percentage was shown by the Beko BRZ-2009 and Vitek VT-1729 BK heaters (3.28% each), the maximum - Timberk TOR 21.2009 HA (-21.2%).

2. Heater warm-up time

At this stage, the time it took for the device to warm up to operating temperature was measured. The heating time depends on the design of the heaters, the location of the heating elements, the brand of oil and other features of the devices.

The initial temperature is room 23 +/-2°C.

This test is carried out at maximum heater power. The fastest was Beko BRZ-2009 (6 min 40 sec), the slowest was Scarlett SC-1167 (15 min 30 sec). The temperature was measured according to the standard, at the hottest point of the case (the hottest point is located for each heater, as a rule, at the bottom, closer to the heating element).

3. Heat radiation efficiency

This is a very tricky parameter. Due to convection, the radiation of oil heaters is predominantly directed upward, and only a small part is directed sideways. And this part, in fact, determines how warm we will be next to the device.

Radiated heat efficiency is the temperature difference in front of and behind a black plywood test bench located a meter to the side of the heater. The maximum efficiency is for Aeronik PO-1123M - 3.85? C, the minimum for Timberk TOR 21.2009 HA - 2.05? C.

WE MEASURE FUNCTIONAL PARAMETERS

This part of the test is one of the most interesting. We will find out how efficiently the devices heat, how the temperature will change while maintaining the set value, how many kilowatts we will use, and we will be able to understand how much additional heat will cost us.

Heating the room

How were the measurements taken? To correctly compare the heating capabilities of the heaters, they were placed in a test chamber: an unheated room with an area of ​​10 sq.m. Each device was tested separately. The heater had both heating elements turned on, i.e. it worked at the maximum heating level. The time it took to heat the room by 10°C and the energy consumption of this process were measured.

The conditions were as close as possible to real ones: after all, in winter there are constant heat leaks in the house both through the windows and through the walls. The more interesting!

The Scarlett SC-1167 heated the air the fastest (65 min), the slowest was the Beko BRZ-2009 (2 hours 51 min). Why is this happening?

For each heater, the thermostat is configured differently: for some, “overclocking” occurs with continuous operation of two heating elements, while for others, with periodic shutdown of one or two heating elements.

Keep the temperature

The second important task of any oil heater is to be able to maintain the temperature in the room while spending a minimum of energy. After the set temperature was reached, it was fixed by smoothly turning the thermostat knob until it clicked. After this, the devices worked, trying to maintain the set temperature.

The operating algorithm for different devices was different: some devices (Aeronik PO-1123M, Scarlett SC-1167, Timberk TOR 21/2009 HA, Unit UOR-920) worked for some time at maximum mode, turning off the heating for a short period of time (from 2 up to 5 min); De’Longhi TRD0820ER alternated operation in maximum and medium modes, and VitekVT-1729 BK - in maximum and minimum modes, Beko BRZ-2009 maintained the temperature, including only the middle heating stage.

Such on/off modes lead to some temperature fluctuations. The smaller this range, the better. The measured fluctuations turned out to be very small. After all, oil radiators are inert: after switching off, hot oil is in no hurry to cool down. The minimum range for De’Longhi TRD0820ER and Unit UOR-920 is only half a degree, the maximum is 1.33? C for Scarlett SC-1167. Such deviations are absolutely invisible without special measurements.

In addition, the temperature change was recorded while maintaining a given heating level - i.e. deviation from the set temperature after a long period of time (several hours of operation until a steady state when the temperature no longer changes). The fact is that heaters tend to slightly “overheat” the room over time. All models passed the test with dignity; the maximum increase of +1.83? C for the Scarlett SC-1167 is very small and imperceptible to humans.

Economical

How much energy will we spend to ensure that in a room of 10 sq.m. Has it gotten 10*C warmer? It turned out that the Vitek model (1.75 kW) spends the least amount of energy on heating, while the Beko BRZ-2009 (2.6 kW) and Aeronic PO-1123M (2.5 kW) are the most wasteful.

In addition, the energy consumption when maintaining the temperature in the room was also measured. The most economical heater turned out to be the Beko BRZ-200 (0.88 kW*h), and the most “expensive” were the De’Longhi TRD0820ER (1.56 kW*h) and Scarlett SC-1167 (1.43 kW*h).

Ease of use and ergonomics

It would seem that the oil radiator is conceptually simple: plug the plug into the socket, and it becomes warm. But this is only at first glance. There are a lot of little things that make working with the device pleasant, and vice versa. This part of the test is intended to introduce us to the ease of use of oil heaters.

Preparing for work

The first thing you have to do after removing the device from the box is installing the supports. A rare specimen does not require screwing on the legs and wheels. In our set, such an extraordinary device was the De’Longhi TRD0820 with its “Easy Wheel” system (see the instructions for the exact name). For other models, the roller bearings are attached to the body with U-shaped holders with wing nuts.

Switching on-switching heating stages

Heating levels are controlled primarily by keys. This is characteristic not only of the devices being tested, but reflects the situation on the market as a whole. In our seven heaters, the De’Longhi TRD0820 and Vitek VK-1729 BK turned out to have a more convenient and expensive design, electronic, which allows you to see on the display what exactly is being switched.

Thermostat control

What should be the adjustment? Smooth, with easy movement of the rotary wheel, if there is one, with a clear click. A click is produced by the bimetallic strip at a certain set temperature level when the heating stops. Aeronik PO-1123M and Scarlett SC-1167 turned out to be close to ideal.

The De’Longhi TRD0820 and Vitek VK-1729 BK were unrivaled with their electronics: both models allow you to set temperature values ​​accurate to a degree. The De’Longhi TRD0820 allows you to adjust the temperature using the remote control.

On the Timberk TOR 21.2009 heater, unfortunately, the handle touches the body when adjusting.

Operation indication

The indicator must be bright! Same as De’Longhi TRD0820 and Vitek VK-1729 BK. These heaters received the maximum score, the rest had a “good” rating.

Marking

What is required from labeling? Visibility, durability, contrast. In general, the devices performed well during testing, but no one earned maximum marks.

Moving the heater

Fortunately, our home heat carrier is not stationary. And if so, he must easily move around the room on rollers. The handle with which you will transport it should be comfortable. The Timberk TOR 21.2009 had the best rollers and handle - the heater received the highest score.

Power cord storage

To wind the cord, as a rule, a special reel is provided at the end. How should the cord be stored? For example, like the Unit, in which it is located on a wide, convenient device, and the plug is clearly attached to the top.

Cleaning and care

The issue of hygiene for a heating device is very, very relevant. A smooth body and a minimum of nooks and crannies where dirt and dust can hide distinguish four of the seven heaters. The De’Longhi TRD0820 protective cover, which added points to the model at other stages of testing, let it down here. There are plenty of hard-to-reach places to clean!

Instructions

Reading instructions is a fun and useful activity. Thanks to him, you can get closer to the acquired miracle of technology, find out what is necessary for it to serve faithfully. Well, or, at least, how to assemble this miracle. The description should be well illustrated, detailed, intelligible and logical, for example, like the De’Longhi TRD0820 and Aeronic PO-1123M. If the font, like the Beko BRZ-2009, is small, it becomes difficult to get to know the device. What can we say about the instructions for Vitek VK-1729 BK, whose font is pale blue and vanishingly small, and the paper is high-quality, glossy... and reflective?

GENERAL RESULTS

The overall assessment consisted of three indicators: functional tests (50%), assessment of technical parameters (30%) and assessment of ergonomics and ease of use (20%).

It's nice that all models received "good" ratings.

The best in terms of ergonomics was the De’Longhi TRD0820ER heater, the leader in technical parameters was the Aeronik PO-1123M, and the winner in the functional tests was the Vitek VT-1729 BK heater.

We also note the most economical (in temperature maintenance mode) oil heater among the tested models - Beko BRZ-2009.

Safety test: there will be no fire!

Fire is a terrible thing, and that is why it is so important that a device such as a heater is truly reliable and gives good warmth without turning it into an evil fire. The safety of heaters, like any electrical appliance, has two sides:

The device complies with all existing safety norms and standards.

Proper operation of the device, strict adherence to all instructions.

Markings and instructions

Tested according to section 7 of GOST R IEC 60335-2-30-99.

Russian safety standards and regulations are very strict, for example, they require that the heater have a “do not cover” inscription on it, especially for those who like to use the heater to dry things.

This inscription in Russian is present on three heaters - Beko BRZ-2009, Timberk TOR 21/2009 HA and Unit UOR-920.

The operating instructions must contain sufficient information for the safe use of the device. From it you should learn:

The device must not be placed close to a power outlet (if high temperatures if there is insufficient heat dissipation, the plastic of the socket may melt or the wallpaper may smoke),

on the procedure for carrying out repairs that require opening the oil container,

about the need to follow the instructions for disposal of oil from a used heater.

All these requirements are met by the instructions for the Beko BRZ-2009 and De’Longhi TRD0820ER heaters.

Protection against contact with live parts

Tested according to section 8 of GOST R IEC 600335-2-30-99.

The designs of all oil heaters provided for testing provide sufficient protection against accidental contact with live parts. It's gratifying!

Power consumption and current

Tested according to section 10 of GOST R IEC 60335-2-30-99.

Not all modern electrical appliances are designed to operate at a voltage of 220 V. There are 230 V, and 220-240 W, and 220-230 V. Therefore, in this test, the power of the heaters was tested strictly at the voltage that the manufacturer indicated in the instructions. Power deviation should not be more than +5%/-10%.

All heaters passed the test, except Timberk TOR 21.2009 ON. IN in this case The consumer was deceived: he bought a 2000 W heater, but they slipped him 1500 W.

Testing of external parts of heaters “Heating”

Tested according to section 11 of GOST R IEC 60335-2-30-99.

The test was carried out in this way - the heater worked for several hours in maximum heating mode. Then, using a test rod with a diameter of 75 mm, the temperature of the external parts of the housing was measured.

This test simulates an accidental touch of the heater with the knee. According to GOST, the temperature of the housing should not exceed the temperature environment 23 +/-2°С more than 85°С. The “coldest” heaters were Beko BRZ-2009 - the temperature of external surfaces did not exceed +71°С, De'Longhi TRD0820ER -+79°С, Unit UOR-920 -+80°C.

It is not recommended to touch other heaters with bare knees or other parts of the body.

Abnormal Operation Tests

Tested according to section 19 of GOST R IEC 60335-2-30-99.

“Abnormal” means operation in violation of operating conditions.

You decide to dry your outerwear on the radiator (during testing, clothes were replaced with special thick felt).

In this case, the device must be smarter than its owners and save them from fire. The temperature of the device body should not exceed +150ºС.

The heaters Aeronik PO-1123M, Beko BRZ-2009, De’Longhi TRD0820ER, Unit UOR-920, Vitek VT-1729 BK successfully completed the test.

A situation is simulated in which a heater operating for a long time overturns onto the floor.

What is the purpose of a rollover test? The oil in the cavity is not filled to capacity. Accordingly, when the heater lies on the floor, it flows into the voids, exposing the heating elements. If there is enough oil, then nothing will happen, since it will remove heat from the heating elements; if not, the elements will heat up, the temperature and pressure in the housing will increase, the oil will boil and fly out, breaking the shell of the housing. A third option is possible: a tip-over sensor installed in the heater simply turns off the device if it falls. The Vitek VT-1729 BK model has such a pendulum sensor.

Heaters Beko BRZ-2009, De’Longhi TRD0820ER, Scarlett SC-1167, Unit UOR-920 also successfully passed the test.

And for Aeronik PO-1123M and Timberk TOR 21.2009 HA the temperature exceeded the permissible value and continued to rise by inertia after the devices were turned off.

Stability and mechanical hazard

Tested according to section 20 of GOST R IEC 60335-2-30-99.

Do appliances tip over that easily? To check this, a simple test was carried out: first, the heaters were placed on an inclined surface (with a slope of 15º). Then a perpendicular blow with a force of 5 N was applied, simulating accidental contact with the device.

All presented models successfully passed the test.

Power Connection and External Flex Cords

Tested according to section 25 of GOST R IEC 60335-2-30-99.

Power cords for heaters can be rubberized or made of PVC.

Among the tested models, Beko BRZ-2009, Unit UOR-920, Vitek VT-1729 BK have rubberized cords, Aeronik PO-1123M, De’Longhi TRD0820ER, Scarlett SC-1167, Timberk TOR 21.2009 NA have PVC cords. Since the PVC cord melts at relatively low temperatures, then, according to GOST, under normal operating conditions it should be unlikely that it will come into contact with the external metal parts of the heater, the temperature of which exceeds 75ºC. Out of 4 heaters with PVC cords, only the De’Longhi TRD0820ER cord meets this standard, because he is wearing a casing.

conclusions

Only one heater passed all safety tests with flying colors - Beko BRZ-2009.

The De’Longhi TRD0820ER model received one remark regarding the labeling.

The instructions for Unit UOR-920 are missing one warning.

Otherwise, these models fully comply with all GOST requirements.

The Vitek VT-1729 BK heater has three caveats: markings, instructions, and excess temperature of external surfaces (“heating”).

Aeronik PO-1123M heater - notes on markings, instructions, excess temperature of external surfaces, did not pass the rollover test, there are problems with the power cord.

Scarlett SC-1167 received comments regarding labeling, instructions, exceeding the temperature of external surfaces, did not cope with “abnormal operation” (drying clothes), there are problems with the power cord.

The Timberk TOR 21.2009 NA heater has the largest number of non-compliances with GOST - in addition to comments on markings, instructions, problems with heating external surfaces, with the power cord, with drying clothes and tipping over (“abnormal operation”), there are also problems with power.

Our central heating is turned off at the wrong time and turned on late. Therefore, maintaining the optimal temperature in the house often falls on the shoulders of the residents themselves. In the most severe cold weather, batteries may remain barely warm. Therefore, purchasing a room heater becomes an urgent necessity. The traditional option is an oil cooler. The best oil heaters will be discussed in our rating.

The structure of the oil heater is simple: inside the steel body there is a heating element placed in oil. The oil warms up and conducts heat to the surface of the heater. In most cases, the surface of the reflector itself does not overheat, which means it does not dry out the air in the room. The heating element does not come into contact with air, so dust is not burned, that is, a favorable microclimate is maintained in the room.

How to choose a good oil heater?

The range of oil radiators on the market is so diverse that it is difficult to choose best model It's not always easy. But this is only at first glance. You just need to take into account some features and characteristics in which heaters differ from each other. And everything falls into place.

Power

The most important, or rather even the main, parameter. Selected based on the size of the room. The simplest generally accepted calculation method is 1 kW per 10 m². Relevant for standard (up to 3 m) ceiling heights. If higher, it is no longer the area (s), but the volume (s*h). We divide it by a special coefficient of 30, we get the required power value:

When using heaters (including oil heaters) in unheated rooms (dacha, garage, warehouse), the formula is slightly different:

where v is the cubic capacity of the room, ΔT is the difference between the desired inside and “outside” temperature, 860 is a constant value for converting kcal/hour to kW.

In addition, the thermal insulation coefficient (k) is applied:

• 0.6-0.9 - for well-insulated houses;
• 1-1.9 - for standard rooms with an average level of insulation;
• 2-2.9 - for buildings with single brickwork, simple roofing and window construction;
• 3-4 - for objects without thermal insulation (wooden or metal).

Device dimensions

For this parameter, in addition to a purely aesthetic one, there is also a practical component. The size of an oil heater is usually directly related to its power. The most common formats: models up to 1 kW have 3-5 sections, for 1.5 kW there are usually 5-7, for 2 kW - 9-10, and for the most powerful varieties for 2.5-3 kW - 11-13.

Another thing is that not only the number of ribs matters, but also their configuration. Small narrow and thick ones heat up more, while wide and flat ones provide better heat transfer and are safer. For families with small children, models with a protective casing on the body are relevant, but it’s a pity that they are not very convenient to wash.

Additional features

Auxiliary functions can be really useful for some, but others can do just fine without them and don’t consider it necessary to pay extra for it. A few examples:

• Drying stand. It is convenient when there is actually a need for it (it is strictly forbidden to place anything directly on the working surface of oil heaters). It's just that its size is small. Experienced housewives usually purchase a separate large folding dryer and place an oil heater under it or next to it.
• All kinds built-in humidifiers, ionizers and other marketing tricks Some manufacturers may have a place, but their effectiveness is rather questionable.
• Built-in fan. It really helps to quickly warm up a cold room of the calculated dimensions and, as an option, warm up limbs that are chilled from the cold. However, the cost increases noticeably, the background noise increases, plus this option “steals” some of the total power. It is also worth noting that faster reaching a comfortable temperature does not mean that the oil heater with a fan is designed for a large area.

Reliability and safety

Currently, almost all oil heaters sold in Russia are made in China. Sometimes you can find co-productions. Of course, radiators are manufactured under license from one of the European companies, but practice shows that this does not greatly affect the quality. Therefore, in the “reliability” criterion, it is worth taking into account not the company that will be written on the box with the new heater, but the functions that will increase safety when using the device.

Do they even allow heaters to be checked? I would like to turn it on, heat it up to peak temperature, then cool it down.
I want to check the maximum temperature, as well as the absence of clicks. But as I understand it, there is no guarantee that the heater will not crack; it’s too bad that such an important parameter is not indicated in the specifications.

11 Mar 2012, 20:28

Just turn it on, heat it up as you wrote, click the buttons and toggle switches, check the serviceability of all controls. The specifications usually don’t say anything about crackling, so it depends on your luck. I think the crackling is due to the weakening of the strengthening of the power electrical parts, the crackling is 50 Hz network. To insure against it, it is better to buy heaters in special stores and only from trusted companies. And when purchasing, be sure to ask the consultants, probably if there is a crackling sound, then someone before you has already complained about it.

How to test an oil heater when purchased in a store?

The cracking noise comes from improper assembly. If the parts are not assembled in accordance with the regulations, then you can expect any surprises from such a heater, including failure. First, turn on the heater immediately at full power and let it warm up. listen to how it works, if there are any sounds, etc. After 20 minutes, turn it off and listen too, if there are no clicks, a certificate and warranty are included, you can safely take it.

How to test an oil heater when purchased in a store?

It doesn't happen once at a time. It happens that you check, everything seems to be working, and you buy it. The warranty will be valid - there will be clicks, no matter what you do. And the warranty is already out. It happens that clicks start after the heater falls, and this is also possible. In general, it is impossible to protect yourself from them 100%.

Follow the tips above.

How to test an oil heater when purchased in a store?

The stores are full of these oil batteries, it’s just dizzying. I wonder who will buy them and whether all of them are of high quality? I think far from it, some woman came to me and returned the purchased goods, saying that either it doesn’t work for you, or she wanted something else. Her heater didn't seem to work. And then, if you bring back the heater and say that it kind of clicks, will they refund the money?

Is clicking considered an objective reason for a return?

How to test an oil heater when purchased in a store?

I recently learned that there is another interesting point. The store gives its own warranty on the heaters, and the manufacturer gives its own. Let’s say the store’s warranty is 2 months; if a breakdown occurs during this time, the product can be returned without any problems.

How to test an oil heater when purchased in a store?

If the breakdown occurs within a year, claims can only be made to the manufacturer; the store does not take part in this. Like this.

You are wrong. The factory warranty applies for the entire period specified in the technical passport (warranty card) and allows you to make claims regarding the quality of the product during this entire period to both the seller and the manufacturer of this product. That is, you can safely go to the store during the entire warranty period. In case of refusal to accept the goods, you should contact Rospotrebnadzor with a complaint.

I just had to face this situation...
According to the manufacturer's warranty, it is written in black and white that a warranty is given for a period of one year, and when sellers fill out the warranty card by hand, they write 6 months. In the event of a complaint investigation, employees who are supposed to protect the interests of buyers take the position of sellers 100%... What do you mean, you signed your own death sentence!!! They signed for 6 months, that’s all... And you can’t prove anything...

In addition, in a number of cases, the warranty workshop does not extend the warranty while the equipment is being repaired... This is a violation...

There are only violations all around, the Federal Service for Consumer Rights Protection and Human Welfare is not enough for them! The idea is that people are unlikely to complain and argue with them if the price of the issue is some inexpensive humidifier, for example, for 1000 rubles, or some heavy product that still needs to be finished, for example, a refrigerator. And if the problem arose with an already mounted gas stove- you understand - dismantling + new connection + delivery. In theory, all this will have to be “pinned” on the seller, but this is not easy.

• Buy heaters that will humidify the air and maintain the necessary microclimate.
• The higher the total area of ​​the sections, the longer the device will heat up. Sections that are too wide will cool quickly.
• It is not recommended to buy devices with light weight and large dimensions; this may indicate the use of thin metal or a small amount of mineral oil.
