The presence of heated water in a house or apartment has become the norm for people to live. The only question is which device will be most effective for heating water for apartments in urban areas or houses located outside the city. A geyser without a chimney should be easy to use and meet the needs in the heated water of all residents who will use it. In some cases, an effective option would be a gas water heater with a storage system, and in others - Tankless water heaters work great.
Geyser without chimney
A practical and convenient solution, especially for apartments located in multi-storey buildings, will be a column that runs on gas and does not need chimney pipe — her more often referred to as turbocharged.

Device chimneyless geyser
This column works for check the released energy of the burning gas, which heats the water, and does not require the construction of an additional chimney. For her natural or liquefied gas from the domestic network or from cylinders can be used.
General scheme of the column device
Such a column does not need the usual vertical chimney pipes - it differs in the principle of removal of combustion products.The combustion chamber of this water heater is hermetically sealed, and a coaxial type of chimney, which through the wall immediately displayed on the street. A hole is made in one of the walls immediately upon installation chimneyless columns. A special fan is built into the column, which directs the products of combustion in the right direction.
Approximate scheme of the output of combustion products
The coaxial pipe is designed in such a way that internal her part of the exhaust gases are removed to the street, and the clean air necessary for the combustion process, served through an external channel.
Coaxial flue pipe
The convenience of such a device is more and that the column does not dry the air in the room, and it does not need to arrange an additional air supply to support combustion. Due to the fact that there is no need to make a separate vertical chimney, there is the possibility of significant financial savings on the purchase of materials and installation work.

Selena SE 3 can also run on propane, but for this you need to spend a little more money and equip the column with special technical devices that will make it “omnivorous” and especially unpretentious to gas quality!
Water heater parameters
An approximate diagram of the operation of a gas column
Choosing chimneyless column, it is necessary to take into account some characteristics, such as power, device performance, safety level, types of ignition and types of burners. The moment of horizontal or vertical arrangement of the device is also important, since the systems for removing combustion products are arranged differently in the columns.
Power
From the correctly selected power of the water heater will depend her performance. Power can be safely called the main parameter that needs to be taken into account. at atgetting a water heater. High power level gives opportunity to receive more volume water heated in flow heating mode.
Performance
On the packaging or in the instructions for use, the performance of the device must be indicated, those. volume hot water produced by an instantaneous water heater in one minute of operation, taking into account definite climb water temperature.
For example, the instructions indicate that by setting the temperature to 25 degrees, the consumer will receive 14 liters of hot water in one minute. If at the inlet to the heating column, the water has a temperature of 8 degrees, then it goes up check instrument operation more at 25 degrees, those. at the exit it will be warmed up to 33 degrees.
If desired, you can make calculation on one's own — for this, the indicator of the power indicated by the manufacturer is divided by two. result fairly accurate counting will be the value of the water dispensed by the column, heated by 26—32 degrees. For example, a water heater rated at 14 liters per minute would have a capacity of 28—30 kW.
When choosing a water heater, you need to take into account the fact that 5.5 is enough for taking a shower, washing or washing dishes. — 6 liters dispensed per minute for each tap used.
Ignition chimneyless water heater
On modern water heaters operating without a traditional chimney, three types of ignition systems are installed — These are piezo ignition, electric ignition and hydroturbine ignition. They provide ease of use of the column and her safety.
- Hydroturbine ignition comes from a hydrodynamic generator. Some modern gas water heaters are equipped with mini hydroelectric power plants, the generator of which is built into pipeline water heater. When water is supplied, it passes through impeller, rotates her blades, and the generator generates the required electrical potential for the igniter. These water heaters do not need additional energy sources for ignition.
- Piezo ignition has a special element, which the issues electrical potential from mechanical impact, at which a spark appears, igniting the burner. With such ignition, there is one inconvenience that will not allow you to save on gas fuel — the igniter must be in a burning state in advance so that when the water is turned on, the main burner lights up.
- Electric ignition requires connecting the column to the mains or installing batteries (batteries or accumulators). The water pressure sensor is activated when the faucet is opened and gives command to ignite the igniter for check spark gap.
Control system chimneyless columns
Burners can be open or closed
The flame control of the burners of these water heaters can be variable (automatic) or constant with stepped power.
- Columns with burners that are automatically controlled, after setting the temperature regime, will work stably, giving out water of a specific outlet temperature, regardless of external influences. As a rule, this is an electronic push-button system with a digital display.
- Water heaters with burners with stepped output make it possible to regulate the flame of the burner, and means, and water temperature, independently. But once done installation is not gives confidence that the column will continue to work in this mode, since on onheating water can be affected by gas pressure, incoming cold water temperature and even changes in barometric pressure.
The temperature is adjusted through turning the faucet handle to one or the other side. Do not twist the handle too much, otherwise you can get the opposite effect. — the water heater may turn off completely. With such an adjustment, it is highly undesirable to mix heated with a column and cold tap water.
Safety chimneyless water heaters
Most consumers think chimneyless speakers are completely safe during operation, but is it? Any appliances that use gas fuel require caution and rules for their safe use.
If one of the elements of the water heater system fails or the coolant overheats, the column automatically turns off. This argument can speak for the increased safety of the device, provided that it is correctly installed qualified.
However, if chimneyless the column is installed in a high-rise apartment, and above this apartment is located more several floors, then the coaxial pipe that removes combustion products from the water heater can become dangerous for residents of the upper floors. Carbon monoxide, after leaving the pipe, rises up, and by the movement of air it can easily be thrown into an open window or even into the window of the upper apartments, and this can cause serious effects.
It looks like the exit of the coaxial pipe on the street
That is why before installing such water heating equipment, it is imperative to consult with gas service specialists. In a private house or with an apartment located on the top floor, you can safely arrange chimneyless column, because it is not will bring no harm to people living nearby.
chimneyless column looks great in the interior
I would like to say a few words about the location of the column without a chimney in the interior of the apartment. She may be locatedon on kitchen or bathroom, if at least one wall of the room borders on the street, since in it and have to arrange a hole for the coaxial pipe. If there is such an opportunity, then there will be no problems with installing a water heater. The advantage of such columns is the absence of unsightly chimney pipes, which rarely adorn the walls.
The column should not violate the harmony of the interior
A water heater mounted on the wall looks neat and does not spoil, and sometimes even complements the interior with its presence.
Before acquiring this necessary and expensive instrument, necessarily weigh the pros and cons, and also calculate its location. If there is at least one condition that may cause doubt, think about other types of water heaters.
