Turbocharged geyser without chimneyIgnition method

Pros and cons of a chimneyless geyser

Gas water heaters operating without a chimney have the following advantages:

• They can be installed in any room. For example, in a new house, where the presence of a chimney for a gas column is not provided for by the project. Or in a country house, in a country house where there is no specially erected chimney;
• Such a device does not dry the air inside the room, which is typical of a standard geyser;
• The air in the room does not heat up, which is especially noticeable during hot weather;
• The efficiency of the water heater is increased by the forced removal of exhaust air. Unlike this type of water heater, in a standard geyser, combustion products are discharged by gravity through a common pipe;
• The combustion chamber of the column is completely isolated, so there are no extraneous odors characteristic of combustion products in the room.

However, this equipment also has certain disadvantages:

• Installing a column of this type is more difficult than a conventional water heater. It is required to drill a hole in the wall, and then carefully close it up, leaving a special nozzle outside;
• Higher prices are set for gas turbocharged columns;
• The presence of a fan requires the device to be connected to the mains. If the electricity in the network disappears, the column cannot be used;
• It is required to coordinate the installation of gas equipment with the relevant authorities, since it will be impossible to hide the fact of the presence of such a column;
• A turbocharged speaker creates an increased noise effect due to a running fan and high-speed air flows. This is noticeable both indoors and outdoors;
• Your upstairs neighbors, if any, may not like such a device, because they will partially get the smell of exhaust gases, and it will also be noisy outside the windows from time to time.

Ignition of a chimneyless geyser

An important component of a gas water heater is the column ignition system. This element affects not only the usability of the device, but also the degree of its security.

In chimneyless gas water heaters, three types of ignition can be installed:

• Electronic;
• Piezo ignition;
• Ignition from a hydraulic turbine.

Devices equipped with an electronic ignition system have one important feature - they do not have to be in standby mode all the time. If it is necessary to ignite the device, a spark is created, the energy for which is taken from the batteries. Ignition is carried out at each opening of the tap, and the rest of the time the system is in an inactive state.

Piezo ignition works due to the piezoelectric effect, i.e. applied mechanical force creates a spark. Unlike the previous design, the operation of the piezoelectric ignition requires a constantly burning igniter, which ensures the operation of the water heater.

Advantages and disadvantages

For apartments where there are no chimney channels, there was previously only one solution for preparing water for the needs of domestic hot water - an electric storage water heater. With the advent of forced-air flow heaters, residents of such apartments have an alternative. This is one of the main advantages of columns with a closed combustion chamber. And here are the rest:

• it is not necessary to organize the flow of air for combustion into the house, the usual supply and exhaust ventilation required in accordance with the regulations is sufficient;
• high efficiency of work, and therefore - profitability;
• gas water heaters without a chimney are fully automated and create additional comfort during operation;
• tandem fan - burner successfully smooth out water temperature drops when several taps are opened within the available power;
• the entry of various combustion products into the room is practically excluded.

Like any other water heater, a closed-type chimney column has some disadvantages. One of them is the high cost of the product compared to conventional flow units. The reason is the presence in the design of additional expensive elements and parts. But look at the problem from a different angle in this situation: the installation of a heater is planned at the stage of building a house. And consider what will be cheaper: installing a traditional chimney and buying a conventional column, or installing a coaxial pipe and purchasing a turbocharged unit.

The heater, which uses a closed combustion chamber and a fan, creates some noise during operation. In addition, the device is completely dependent on the availability of electricity, so it cannot be used in areas with frequent blackouts. Or you will need an alternative source of electricity, such as a gasoline or diesel generator.

Due to the complexity of the design, do-it-yourself maintenance and cleaning of the water heater is excluded. If you decide to install a turbocharged column, be prepared to contact the service departments for troubleshooting. More information about the products can be found by watching the video:

Speaker types

Well, the last thing worth focusing on is the types of closed-type water heaters without a chimney. There are two of them:

• Variables. With automatic adjustment. The column itself reacts to the temperature of the incoming water and, depending on it, increases or decreases the intensity of combustion.
• Permanent. These models allow the user to independently regulate the temperature of the outlet water. Is it convenient? Not always. In an apartment connected to a central water supply system, such a question may not arise. But in a private house, the operation of the column can be affected by factors such as changing pressure when gas is supplied, an increase or decrease in the temperature of the water supplied to the column, and even atmospheric pressure.

So this factor also needs to be taken into account.

That, perhaps, is all that could be said on this issue. It remains to wish your water heater many years of service, and you convenience and comfort in your own home.

If it so happened that there is no hot water supply in your house, but there is gas, then you need a geyser to heat water. Specialists of "Expert Price" analyzed the models of gas water heaters that buyers were most interested in in 2017 and early 2018, and chose the 10 best ones. Now you will learn about them. But first, let's choose a manufacturer.

Ignition

Modern instantaneous water heaters that work without the use of a conventional chimney, have three types of ignition system
– hydroturbine ignition, piezo ignition and electric ignition. They create ease of use of the column and its safety.

Hydroturbine ignition is carried out from a hydrodynamic generator. Many modern appliances have built-in mini hydroelectric power plants, the generator of which is installed in the water heater pipeline. The incoming water passes through the turbine, rotating its blades, and the generator begins to generate the necessary electricity for the igniter. Such water heaters do not need to install additional energy sources necessary for ignition.

Piezo ignition has a special element that generates electrical potential from mechanical impact, as a result of which a spark appears, with which the burner is ignited. This ignition has one drawback - the igniter must be in a burning state in advance
so that when the water is turned on, the main burner ignites.

For electric ignition, it is necessary to connect the column to the electrical network or install batteries, such as accumulators or batteries. When the tap is opened, a water pressure sensor is activated, which gives a command to ignite the igniter using a spark gap.

The flame control of the burners can be variable or constant with stepped power.

The temperature is adjusted by turning the tap handle to either side. Don't over tighten it because can have the exact opposite effect.
- the instantaneous water heater can simply turn off. With this adjustment, it is forbidden to mix cold water from a tap and heated using a column.

Most people consider the operation of gas water heaters without chimneys to be absolutely safe, but it is still advisable to exercise some caution.
and rules for the safe use of the device. If one of the elements of the water heater system suddenly fails or the coolant overheats, the column will turn off automatically

This confirms the increased safety of the gas appliance only if it is installed correctly.

If one of the elements of the water heater system suddenly fails or the coolant overheats, the column will turn off automatically. This confirms the increased safety of the gas appliance only if it is installed correctly.

But if such a device is installed in an apartment of a multi-storey building, and several more floors are located above this apartment, then the exhaust products of combustion from the heater coaxial pipe can become very dangerous for residents
located on the upper floors. Carbon monoxide coming out of the pipe begins to rise and it can easily enter the open window of the apartment located above with a stream of air, which can create serious problems.

Therefore, before installing such equipment, it is best to consult with gas service workers. But in private houses or apartments, which are located on the top floor, such a column can be installed without any fear of harming anyone.

Before you buy an expensive gas water heater without a chimney, you should evaluate its advantages and disadvantages. In addition, you need to find a place where it will be placed.

If at least something raises doubts or difficulties, it is best to pay attention to other types of water heaters.

Convenient Horror. I will explain why everything is so, if there is no chimney and there is no desire to pay a lot for light, then Vector or Oasis, alas, there is no other

I put column 2ku. Because despite its price and ease of use, there are huge disadvantages: and this is that it is not eternal and if you buy for a family, it breaks down within a year.

BUT ACCORDING TO THE TEXT, I WILL REPEAT AGAIN: IF IT IS NOT POSSIBLE TO SUPPLY AN ELECTRIC WATER HEATER, YOU WILL HAVE TO PAY TOO MUCH FOR LIGHT, THERE IS NO CHIMNEY, THEN MAKE A SUPPLY FAN AND BUY! NOW INSTEAD OF VECTOR OASIS. INFA FOR 2017. WE HAVE AN OASIS FOR ABOUT HALF A YEAR, TFTF- EVERYTHING IS OK. BETTER THAN PAST VECTORS. YOU CANNOT READ THE REVIEW FURTHER. I SAID EVERYTHING IN THIS PARAGRAPH.

by the way, we even installed an instantaneous water heater, but I don’t remember the company, it costs about 2-3 thousand, it exploded (it’s good that there was no one in the kitchen, because the plaster fell off the wall from the impact. in the places of impacts. after that we bought an Oasis .

1. We and our friends bought a column. Also a family. The column pleased us for about 5-6 months. just worked for about 20-25 seconds and rotten.

I tried to repair it, they regulated the water pressure, and the gasmen were still turning something in the column. There was no sense anymore. They even smeared the wicks with alcohol. useless. Friends suffered for a couple of months, repaired the old one, threw this one away.

We tried to use it for a whole year. repaired, but all in vain. We decided to buy the same new one. It's good that it costs only 3500 rubles. a year is a penny.per month for 292 rubles. per day at 9.5. Installed today. I hope it will work. (Fuck sang there, sorry, but for half a year and the column just lit up when turned on, it worked for 30 seconds and went out. )

2. According to the project in our house, a waste-free gas column is laid. Or a water heater. But the water heater takes about 200 kW-350 per month. If you use it without straining. Wash dishes, wash, etc. And even more so. happens of course.

If the TV, refrigerator, hair dryer, computer, and water heater in the apartment consumption and 400-500 kW. who saves. not about that.

In general, such columns are harmful in that there is no chimney, and combustion waste is distributed throughout the apartment. you need a hole in the wall with a screw. in our city, people died from such speakers. There is also a lot of information on the Internet. It's good that the government banned them. BUT WHAT TO DO if there is no desire to pay for electricity, there is no chimney and there is no chimney, we are carefully looking for the Vector, but they are sooo hard to find, or the Oasis, which we now have, by the way, costs half a year. so far everything is ok. it is slightly better than the Vector.

the price is also 3000-5000 thousand rubles. who is selling.

Another minus: It turned out that the tube was leaky and began to dig. visible in the photo.

I listed the pros in the merits. But I would not recommend this particular column to anyone. Maybe we're not so lucky. If someone had the same problems with her .write. share your experience. What have you done with it.

The second time we put a column of the same company, after the first leak. There is no choice either a chimney or a boiler. but damn. in a house without grounding, thanks to our UK, krivorukov.

ok.set, used for almost a year, until it just began to go out. when the tap was turned on, it lit up, worked for a few seconds, 20-30 and went out. ppc..

They called Gorgaz to clean, repair, Chinese sensors simply work so well that they turn off the column, gas is supplied, but the water does not heat up, the fire does not burn, carbon dioxide appears in the apartment and there is a risk of poisoning and fainting, I worked for several years in housing and communal services in the sphere of light, water and gas, and now I know firsthand that such columns are VERY DANGEROUS!

We removed the column. But you need warm water. Anyway, we bought another one over the past 5 years, that we live in an apartment, this is already 4. but the Oasis company. similar to use, but tftf does not break.

Thank you for the time spent on my review. I hope it will be at least a little useful to you.

that you look for a more suitable and safe option so that you have hot water in the apartment.

But life is more precious than anything. I knew people who died from being burned out while the wife was washing in the bathroom, the husband watched TV and even the poor cat walked around the apartment. Found them 3 days later. IT IS A FACT!

The main reasons that the Oasis column does not ignite

Sometimes consumers wonder why the Oasis chimneyless gas column does not turn on. This failure could be caused by several factors. First of all, it is necessary to check whether the pipes are connected correctly. The water heater has a special design that will not work if the outlet and inlet pipes are connected incorrectly.

The most common and frequent reason for the failure of the geyser from work is the lack of traction. If there is clogging with foreign objects or dust, the burner will simply go out. The protection system will work, which will cut off the fuel supply. If the column still ignites, but goes out after a while, then a sensitive protective relay may become the reason for this. When the windows are closed, the relay overheats, its protection is triggered. In this case, it is necessary to open the window or window. This measure is temporary, because the relay in this case must be replaced.

Features of turbocharged geysers

We note right away that the units of this type still have a chimney.The term "flueless column" is used in the sense that a gas-using installation does not need a traditional natural draft chimney. This is one of the many features that distinguish gas water heaters with a closed combustion chamber. Natural draft is not needed, because the device has its own, forced, provided by a fan. A special double-walled (coaxial) chimney is used to supply air and exhaust gases.

Now let's collect all the technical solutions implemented in the turbocharged water heater into one list, and then consider each of them separately:

• automatic ignition system using electricity;
• forced removal of flue gases and suction of combustion air from the outside with the help of a turbine;
• sealed combustion chamber;
• modulating burner;
• electronic control unit;
• system preventing defrosting of the heat exchanger.

Since turbocharged geysers are always connected to the house electrical network, the ignition system in them is electrical. On many Internet resources, you can find information that piezo ignition or sparking from batteries is used in supercharged units. These data are not true, there is no point in embedding batteries in a device connected to a 220 V network. Not to mention manual piezo ignition, which is absolutely incompatible with the operation of automation equipment.

A fan installed in a turbocharged geyser performs 2 tasks: it pushes combustion products into the coaxial chimney and draws air from the street into the chamber, bypassing the room. In heater circuits from various manufacturers, the turbine can be implemented in different ways:

• as a blower - the fan is located at the beginning of the gas-air path, in front of the burner and blows air into the closed chamber;
• as a smoke exhauster - the turbine is located before the exit of flue gases, behind the heat exchanger, and operates in suction mode.

The combustion chambers of turbocharged columns are airtight only conditionally. This means that they are separated from the indoor air, but communicate with the street, so there is no significant overpressure in them. The bottom line is that the fan supplies exactly the amount of air that is required for combustion in one mode or another. The performance of the blower (or smoke exhauster) is controlled by the controller.

In tandem with the fan, the gas burner of the apparatus functions. According to the principle of operation, it is modulating, that is, it is capable of automatically changing the intensity of combustion in automatic mode. In this case, the gas burner device is guided by changes in water pressure that occur due to an increase or decrease in water intake.

All processes in the heater from the beginning to the end are controlled by an electronic unit - the controller. Focusing on the sensor signals, the latter regulates the burner power and fan performance, and in the event of an emergency, it gives a command to shut off the gas. However, the circuit is designed in such a way that in the event of a serious accident, the gas valve itself will turn off the fuel supply, without a command from the controller.

And the last innovation is a system that protects the heat exchanger from defrosting when the room temperature drops below 0 ºС. The anti-freeze geyser is equipped with a special electric heater that automatically turns on at a temperature of 0 ºС or lower in standby mode, when the water in the heat exchanger tubes does not move.

How to calculate power

First, why is it needed? To ensure that the temperature of the water does not suddenly drop during showering or washing dishes due to the fact that the appliance has not coped with heating the required amount of water.

Second, how to do it. And again, it's pretty simple.In the passport of the device, the manufacturer must indicate the performance of his product. And if it's simpler - how many liters of water it heats up in one minute.

A simple example: the passport indicates that the column is capable of heating 15 liters by 25 degrees per minute. That is, every minute 15 liters of hot water will flow into your water supply system. Temperature differences must be taken into account here. That is, the water will not be exactly 25 degrees. This value should be added to the initial temperature. So: water entered the column, having its own temperature of 7 degrees. I heated up another 25 and the output turned out to be 32. Here is such a simple formula.

But how much water is needed in liters? The calculation is also quite simple. It is based on the fact that approximately 5-5.5 liters per minute per one draw-off point. That is, if all your household members simultaneously take a shower, the second wash the dishes, and the third wash, then all together they will spend about 15 liters per minute. Agree, this rarely happens, so the power of the device given in this example is quite enough for an ordinary apartment in which a family of three or more people lives.

Ignition method

A factor that in most cases few people pay attention to

However, it is also important to know this in order to choose the right model correctly. There are three ways in total:

• Piezo ignition. What is a piezoelectric element is hardly worth explaining. But to mention that this is the most uneconomical option is necessary. This option implies a constant burning of the igniter, and hence a constant gas flow, albeit in very small quantities.
• Electronic. Powered by two AA batteries, it turns on automatically when the tap is opened and does not require constant operation of the burner.
• Ignition from a microturbine. Absolutely autonomous function, independent of the connection to the mains or the presence of batteries. A mini-hydroelectric power station is installed inside the device, which generates and accumulates enough energy to carry out automatic ignition.

The built-in methods of ignition have practically no effect on the price, but very much even on the ease of use and efficiency of the device.

The main advantages of the column brand Neva 4505

Chimneyless geysers "Neva" are one of the most popular on the market. Among others, it is worth highlighting the model that was mentioned above. It is a water heating device. The device can use liquefied or natural gas in operation. It is noteworthy that the unit can be connected to bottled gas.

As practice shows, 6 liters of water per minute can be obtained using this geyser. At the same time, harmful substances are emitted into the room 1.5 times less compared to a household gas stove. Among other things, this model is equipped with oxygen sensors and timers that are responsible for turning off the equipment if the level of combustion waste exceeds the norm. The power of the equipment is 9 kW. You will have to pay 4500 rubles for it.

Useful tips to ensure long and reliable operation of gas water heaters

1. Installation and connection must be carried out by qualified personnel. Often, the quality of its work depends on how the geyser is set up.
2. It is necessary to regularly clean the igniter and heat exchanger from combustion products (it is strange to blame the column for blockages). This will significantly extend the "life" of the device.
3. In old houses with too low water pressure in the system, it is better to install special pumps. With a stable water pressure, automatic start-up occurs without problems, and the heating temperature will be maintained more correctly.
4. It is necessary to follow the important recommendations from the manufacturer indicated in the user manual

If you often encounter problems with the supply of hot water, then you can take advantage of the excellent opportunity to sort out the operation of the hot water supply system. To do this, you need to purchase a gas column. However, not every house has the opportunity to install such equipment, because the column functions by removing combustion products through the chimney.

In this case, a turbocharged model that does not have a chimney and is also known as a drawless column can help out. If you decide to purchase such a device, it is recommended to first familiarize yourself with the pros and cons of such equipment. This recommendation is due to the fact that some consumers refuse to purchase chimneyless gas water heaters for several reasons, among which the complexity of installation should be highlighted.

2 Types of columns without a chimney and their differences, prices

First of all, geysers without a chimney vary by manufacturer. There are enough models on the market both from representatives of foreign brands (geyser power without a chimney) and domestic brands (geyser Vector 11n without a chimney). The main difference between the representatives of these two groups is the cost and quality of products. According to generally accepted stereotypes, imported models are of higher quality than ours. Sometimes this is so, but not always. Moreover, if we take into account the prices for gas water heaters without a closed chimney of foreign manufacturers, and compare them with Russian models, the difference can reach 30%.

If you pay attention to reviews of a gas water heater without a national-made chimney, you can trace the trend according to which people are increasingly supporting just such models, due to the improvement in the quality of the latter, against the backdrop of rapidly growing competition.
The next criterion that differentiates gas water heaters without a chimney is the location of key mechanisms. This classification affects the ease of operation and installation of the device.

Geysers without a chimney can have a horizontal arrangement, as well as a vertical one.
Next, you should decide on the type of gas column: storage or flow. Storage water heaters without a chimney are less common, as they are more expensive, usually take up a lot of space and are less versatile. Whereas flow-through gas water heaters without a chimney (Neva gas water heaters without a chimney) are the leaders in the segment, and they heat water immediately after the latter passes through the system.
Most gas water heaters are designed to function when assisted with natural gas. At the same time, sometimes it is advisable to use a liquefied gas water heater without a chimney. Such a device can use as fuel not only gas from the system, but also liquefied gas from special cylinders, which is very convenient and relevant for regions and districts where, for certain reasons, there is no access to a gas pipeline (dacha, in a remote area, etc.) .

The price of a geyser without a chimney is approximately on the same level as water heaters that have an open combustion chamber. Speaking specifically, medium-power models have a cost of 8 thousand rubles (domestic manufacturer) and 10 thousand for imported models.

Gas column device without chimney

2.1 Tips for choosing columns without a chimney, their pros and cons

In order to buy a gas water heater without a chimney, you should know some features of choosing the right model:

• First of all, you should decide on the budget, calculating not only the cost of the device, but also all associated costs (transportation, installation);
• Selection of a place in your premises;
• Measuring the size of free space (using this, you can choose a model based on the maximum allowable dimensions, specifically at your premises);
• Be sure to find a reliable supplier (seller) who can provide you with a product warranty;
• Make sure the kit is complete: factory box, fasteners, instructions, and related documentation (technical data sheet);
• Calculate the required power of the device, taking into account the declared gas consumption.
