Geyser "Oasis" - customer reviews, types and characteristics

The water heater is gradually becoming one of the indispensable things that are found not only in country houses, but also in comfortable apartments. Modern manufacturers supply high-quality products to the market, because competition is high. Oasis gas water heaters are very popular among consumers, reviews of which you can read below.

This equipment belongs to the middle class and skillfully combines reasonable cost and decent quality. In order to choose a suitable model, you need to pay attention to the characteristics of the models, their positive and negative sides.

The main types of speakers from

Water heaters are classified according to their operating principle. Products can be flow-through or storage. These units have different heating mechanisms. Flow columns are the most common today. With their help, you can get stable and constant heating of water, and pressure will not affect this.

Instantaneous water heaters are classified by performance. In one minute you can get from 6 to 13 liters of heated water. Gas water heaters "Oasis", reviews of which should help you make the right choice, also differ from each other in power.

Customer reviews about flow models

Among the positive aspects of flow equipment, buyers highlight:

• automatic switching on;
• the presence of a regulator that controls the water heating process;
• no dependence on electricity;
• opportunity to minimize costs.

As for the lack of dependence on electricity, it is ensured by operation, which is carried out using replaceable batteries. The design provides for a regulator with which you can control the heating process depending on the time of year. Consumers emphasize that flow-through models also have their disadvantages, which are expressed in the high cost of the devices. But buyers emphasize that such devices pay off in durability and practicality.

Reviews of storage columns

After reading customer reviews about Oasis geysers, you can understand that the principle of operation of storage devices is completely different. Water is heated in a special tank, which is well insulated. Consumers consider the advantages of such units to be:

• availability of a constant volume of hot water;
• comfortable operation;
• economical work.

Cumulative models, according to consumers, also have their disadvantages, they are expressed in the large size of the structures and high cost. If there is not much free space in the apartment, then placing a storage column will be quite difficult. Buyers emphasize that it is better to purchase such equipment for a spacious private house than for a small city apartment. In the latter case, some difficulties may arise with installing the device.

Despite some disadvantages, consumers quite often purchase Oasis brand products. Customer reviews of the Oasis gas water heater will allow you to verify this. According to consumer opinions, storage models can be quite compact. However, the volume of the water tank will not exceed 15 liters. For a modern small-sized kitchen, such equipment will be a real godsend.

Not enough charge

When you open the water, you observe a normal flow, when you turn it on, there is a characteristic click, a spark is formed and everything is generally visually good. But there is one noticeable point: the burner itself in the gas water heater does not ignite. If you look through the window, there is no flame. This is the reason why there is no hot water. The owner does not have hot water, which causes a lot of inconvenience. This reason must be eliminated as soon as possible.

The reason for the malfunction and lack of hot water lies in a completely simple phenomenon. When the batteries stop working, the speaker stops functioning. It does not heat up and therefore the hot water supply stops.

The battery charge in the final stages is only enough to produce a spark. Therefore, visually you observe a spark, and there is also a noticeable click. But the battery energy is not enough to ignite the burner itself.

Replacing the batteries yourself is not difficult. To do this, you need to open the box with the batteries and take them out. Next, you should replace it with new, high-quality, powerful batteries.

More about batteries

Polarity in batteries matters. If you insert batteries without taking into account their polarity, the column will not light up. Batteries can sometimes get stuck in the pack, so keep an eye on them.

Replacement with new functioning batteries is carried out if two main criteria are met:

• The polarity of the batteries must be taken into account;
• The box intended for batteries must be closed until it clicks.

The batteries used in geysers must be standard D (in other words, barrel batteries). Salt options are not suitable because they have the ability to quickly fail. In most cases, alkaline batteries are used for geysers. They are otherwise called alkaline batteries.

There are often cases when a person purchases batteries, but they do not light the column. Here, too, several questions arise as to why even new batteries cannot cope with their functions. At this stage, the owner may also become confused and look for a completely different reason. In order not to find yourself in such an unpleasant situation, you need to wisely choose batteries for the operation of the gas water heater. There are a few tips to keep in mind...

Tips for choosing batteries

It is not advisable to choose too cheap ones. In this case, it is recommended to choose more expensive batteries (normal ones cost about 200 rubles). If you buy cheap ones, they most likely will not work properly, which means that in the future you will need to overpay

Therefore, initially purchase good quality expensive batteries; Pay attention to the expiration date of the batteries; As for brands, Duracell and Energizer brands are preferred. The battery must be alkaline or lithium.

It will be more informative to use a specific multimeter tester that accurately determines the charge. Anyone can use such a tester; it won’t be difficult. This method is convenient and practical to use, and you can purchase a battery tester at any store.

Reviews of the Turbo W/TUR 20 speaker

Reviews about the Oasis gas water heater will allow you to understand whether you should opt for one model or another. W/TUR 20 is no exception. According to consumers, this instantaneous water heater is an ideal solution for providing an apartment or house with hot water.

The equipment can be installed in a room where there is no permanent chimney. You can install it autonomously, and the fundamental difference from automatic traditional models is expressed in the forced emission of combustion products.

Consumers like that there is no need to replace batteries, because the speaker runs on mains power. It is fully automatic and turns on/off when the tap is opened or closed.

Scale on the heat exchanger - how to fix it

The need to clean the heat exchanger is usually caused by the following reasons.

• The water takes a long time to heat up.
• Poor water pressure.
• The overheating sensor is triggered and the column turns off.

If the above happens to the column, this means that it is necessary to clean the heat exchanger, since a large amount of scale has formed in it.

Step-by-step instruction

Cleaning the heat exchanger consists of the following steps.

1. It is necessary to shut off the water supply to the heater with the valve and dismantle the heat exchanger, disconnecting it from the water pipes. If cleaning is carried out infrequently, it is recommended to use a lubricating spray for dismantling, which makes it easier to unscrew the oxidized nuts. After treating the nuts with a spray, you need to wait 15-20 minutes and start unscrewing them.
2. After dismantling the heat exchanger, you can begin cleaning it. To clean scale, you can use a solution prepared at the rate of 100 grams. citric acid per half liter of hot water. Using a watering can, the solution is poured into the heat exchanger and left there for 12 hours.
3. Afterwards, you need to drain the solution and rinse the part thoroughly with clean water. It is necessary to thoroughly clean the heat exchanger from any remaining scale, as it can clog the tubes, blocking the flow of water. This can be done using pressurized water or compressed air.
4. The final stage at which it is necessary to install the heat exchanger in place in the heater after first changing the sealing washers.

Specifications

Reviews about the Oasis Turbo gas water heater, which were presented above, should help you make the right choice. However, it is also important to pay attention to the technical characteristics, among them the rated thermal power, which is 18 kW. When operating the device, you should expect a flow rate of 10 l/min.

The white body can fit into any interior. The pressure of natural or liquefied gas is 1.3 kPa. The minimum water pressure is 20 kPa. The nominal gas flow rate is equivalent to 2.3 m3/hour. To connect this gas water heater "Oasis", the reviews of which are only positive, you will need to know the diameter of the chimney. It is 60 mm.

Before purchasing a product, it is important to pay attention to additional functions, namely mechanical control and the ability to adjust the flame, as well as water flow. The equipment has an auto-ignition function and a gas control option. The case has a built-in display and also has a temperature display. The structure is made of metal. The design has a modern design, is compact and works with forced emission of combustion products. Dimensions are 340x590x145 mm. The equipment weighs 9.5 kg.

Sources of accident

There are several reasons for burner failure, the main ones being the following factors:

1. Lack of traction.

For any model, be it Neva, Oasis or Vector, the flame goes out or does not light up due to the fact that the chimney is often clogged with dust, dirt and foreign objects. In modern equipment, in this case, a safety valve is activated, shutting off the fuel supply to the gas column automatically. This happens because combustion products are not removed in full and in accordance with technical requirements.

To verify the malfunction, you need to check the traction. To do this, open a window and bring a lit match or a sheet of paper to the pipe. If the chimney is clogged, the wind will not be felt, so the gas water heater will not light. Specialists are engaged in cleaning the combustion waste removal system

It is important not to miss this moment, as exhaust gas enters the room, which can lead to serious consequences

Sometimes the automation is triggered when a nearby hood is on, and the flame goes out or does not appear. If the device has high power, it interferes with the removal of waste, so you should never install two units in one place, especially in small rooms.

2. Sensor malfunction.

If the pilot flame goes out, it is necessary to inspect the device that controls the exhaust of gases. To do this, disconnect the wires and check the resistance using a special device. The indicator must be indicated in the passport; if it does not reach the optimal value, the sensor will have to be replaced. The burner goes out if the thermocouple breaks down. In this case, the geyser does not ignite due to low voltage, the optimal parameter of which is 10 mV.

3. Discharged batteries.

The main function of the batteries is to keep the valve open during operation. The service life of the elements is no more than a year, so manufacturers of gas units such as Neva recommend changing batteries on time. In addition, the reason that the burner does not ignite may be a malfunction of the piezoelectric element or the power cable. It is necessary to disconnect the wires and check them for internal and external breaks. If there is still no spark, the column does not turn on, then the source of the problem is different.

4. Interior clogged.

If dirt and soot get into the gas supply tunnel from the fittings to the burner, the flame goes out or does not ignite. The injectors need to be cleaned. If the fuel pressure is not adjusted, a characteristic whistle will be heard, the flame will come off, and then it will disappear. Also, a burner of the wrong diameter can create such a malfunction. In this case, you need to adjust the gas supply or replace the elements. When aired, the gas water heater ignites, but immediately goes out. To eliminate the defect, you need to unscrew the nut on the fitting and bleed the air, then return the mount to its place, fix it and check whether the burner goes out.

5. Deformation of elements.

If the water is too hard, scale appears in the pipes, which gradually clogs the filters, so the gas unit goes out or does not turn on. The grate is removed and thoroughly cleaned. If it has become damaged due to deposits, it is better to replace it.

The membrane of the water supply unit often breaks, so the column does not turn on. To determine its condition, remove the top cover of the case. The plate should not have cracks or breaks, have the correct shape, smooth and even. In case of the slightest deformation, it will have to be replaced. It is better to choose a part made of durable and elastic material that is resistant to temperature fluctuations and the influence of scale. The membrane must be installed carefully, pressing the fasteners around the perimeter.

6. Water pressure.

As in the situation with draft, the automation blocks the gas supply; if the supply is poor, the burner goes out immediately. It is worth contacting the utility services to find out the reasons and turn off the unit until then. You can use the column only if the water pressure is normal. In private homes, pressure is increased using a compact station and regulator. If the column turns on and works normally, but the water still comes out cold, the device may not have enough power, the parameters are noted in the passport.
