The principle of operation of a turbocharged gas column without a chimney – selection criteria

Two of the most important factors when it comes to heating our homes are safety and efficiency. The turbocharged gas column without a chimney is one of the many options we now have thanks to technological advancements. This cutting-edge heating solution provides flexibility and convenience, but it’s important to grasp how it works and choose the best one for your house.

Thus, what precisely is a gas column that is turbocharged but lacks a chimney? In short, it’s a heating appliance that produces heat for your house using gas as its fuel source. These turbocharged models can be used in a range of housing situations because they use an alternative method to expel combustion gases, unlike traditional gas heaters that need a chimney for ventilation.

These devices work on the basis of a combustion process that releases heat through the burning of gas. However, turbocharged gas columns use a fan-assisted system to safely expel these gases outdoors, rather than depending on a chimney to do so. This not only makes a chimney unnecessary but also gives you more options for installation inside your house.

Choosing the appropriate turbocharged gas column for your house requires careful consideration of a number of important factors. To begin with, efficiency is crucial. To make sure you’re getting the most out of your fuel consumption while controlling your energy bills, look for models with high energy efficiency ratings.

To make sure the unit sufficiently heats the area in which it is installed, take into account the unit’s size and heating capacity as well. To prevent inefficiencies and discomfort caused by under- or oversizing, proper sizing is essential.

Furthermore, while selecting any heating appliance, safety should always come first. Ascertain that the model you choose conforms to all applicable safety standards and laws in order to reduce the possibility of mishaps or malfunctions.

You can choose the ideal turbocharged gas column without a chimney with confidence to heat your house effectively and safely if you comprehend the basic principles of operation and take these selection factors into account.

Criteria Explanation
Efficiency Turbocharged gas columns without chimneys are designed to efficiently heat water without the need for a traditional chimney. Look for models that offer high efficiency ratings to ensure effective heating while minimizing energy waste.
Safety Features Since these systems don"t have a chimney, it"s crucial to prioritize safety features such as automatic shut-off mechanisms in case of malfunction or gas leaks. Choose a unit with robust safety features to protect your home and family.
Ventilation Requirements Consider the ventilation requirements of the turbocharged gas column. While they don"t require a chimney, they still need adequate ventilation to ensure proper combustion and prevent the buildup of harmful gases like carbon monoxide. Ensure your home has sufficient ventilation or install additional ventilation if necessary.
Size and Capacity Choose a turbocharged gas column that suits the size and hot water demands of your household. Consider factors such as the number of bathrooms and occupants to select a unit with the appropriate size and capacity.

How is a turbocharged gas column

The principles governing the operation of the old and new water heaters are the same. Water circulates through a heat exchanger that is heated by a gas burner with turbocharger.

The device’s dimensions have remained essentially unchanged, as has the amount of water and heating intensity. The design of the combustion chamber, the process for supplying air for burning gas, and the elimination of combustion products have all undergone significant modifications.

A contemporary gas column that is turbocharged is installed to heat water instead of using a traditional chimney. The same kind of smoke pipe is no longer required. This implies that the water heater can be mounted anywhere along the apartment or private home’s exterior capital wall.

The device’s design has grown increasingly intricate, encompassing:

  • Dymosos fan;
  • A new -sample heat exchanger;
  • Closed turbocharged combustion chamber;
  • a burned device of a modulated or non -dummy type;
  • ignition unit;
  • control system system;
  • pneumohydraulic and gas valves.

The case has smaller dimensions. Medium measurements: 50–60 cm tall, 35–40 cm wide, and 10–15 cm deep. The old sample chimney has been replaced with a coaxial chimney. A turbocharged column can produce 8–20 kW of power. Water usage: 6 to 12 liters per minute.

The gas water heater has two separate sensor systems. A turbocharged column cannot function without the first, which offers sustainable work. For instance, the thermocardor fixes the presence of the combustion front, and the press-steaming determines whether traction exists in the air removal system. The pneumatic hydraulic valve’s micro-circuit breaker only turns on the power supply when there is water pressure at the heat exchanger’s inlet and gas in front of the nozzle.

The security group comprises the second set of sensors. For instance, a sensor for overheating and water boiling in the heat exchanger is present in different models. The thawing sensor of the gas column’s water circuit is another option for installation. Even a valve to prevent excessive pressure from the water circuit in the event that the mixer’s column boils with the GV cranes closed is included in less expensive models.

Typically, brand-name gas water heaters have an electronic component that controls the operating modes through a microprocessor. There is a screen on the front surface that displays the temperature of the water. You can adjust using the remote control or by turning the handle.

Principle of operation

A turbocharged column’s mechanism is similar to that of a contemporary non-diving heating boiler. The heating apparatus differs only in that the gas in the burning device is periodically burned for brief periods of time, ensuring that the water in the heat exchanger is heated.

The hot water crane is open, but the combustion front in the gas column remains constant. Maintaining a gas burner in a burning state is more manageable than turning it on and off several times per minute. Consequently, a non-dummy column with turbocharging is simpler and more dependable. A device called an electric carbon is used to draw air into the combustion chamber. The only device that draws air is the fan, which does so via the coaxial chimney pipe rather than the kitchen area.

It is commonly acknowledged that the noise produced by the smoke exhaust fan in gas speakers without a chimney and closed chamber is extremely loud. The noise level is actually no louder than that of a gas wall boiler.

Furthermore, practically any room with at least one outer wall can accommodate a gas column thanks to the chimney’s coaxial design. As a result, the issue with the curious turbocharged column is overstated.

Coaxial chimney

The absence of a chimney pipe or new circuit will prevent a turbocharged gas column from operating. For a long time, there was the notion to exhaust gas combustion products through a wall-mounted chimney. In actuality, the pipe was extremely heated—even with thermal insulation—which resulted in seal burnout and wall material degradation.

The efficiency of a turbocharged gas column is lower because it creates chimneys that are much hotter than those of a double-circuit boiler.

The coaxial scheme’s chimney is made up of two 90- and 60-mm-diameter stainless steel pipes that are inserted into one another. Hot combustion products are blasted out into the street on the internal insert.

The turbocharged column’s inner and outer walls separate, allowing fresh air to enter the closed combustion chamber. The coaxial chimney’s outer surface is cooled by the air flow to a temperature of 30 to 40 °C, allowing the pipe to be cut into the wall using standard mounting foam.

Since the output flange of most turbocharged gas stems is situated on the upper plane, the chimney is connected to a rotating knee of the same structure. Generally speaking, the chimney can be removed from the column with the kit at a distance of 60 cm.

Inserts up to 150 cm in length can be used to extend the chimney if needed. This implies that only the outer wall needs to have a turbocharged column hung from it. The water device can be moved to the internal partition if needed.

Closed combustion chamber

The way that gas is burned has changed in the new turbocharged gas column. The heat exchanger was positioned above the gas burner in the earliest models of hot water devices, and the burning front had fractures. The burning device’s body is set inside a metal box in a turbocharged column, and a heat exchanger is securely placed on top of it. The turbocharged column consequently revealed a totally closed combustion chamber.

The design is tightly packed, but the firebox is not sealed. There is almost no air leakage from the kitchen area because the outer casing is connected to the coaxial chimney’s supply part. This is a huge benefit because cooking on a gas stove does not clog the heat exchanger with water-fat condensate.

The appearance of the heat exchanger in a turbocharged column and the gas boiler’s heat-expenditure apparatus are different. A traditional plate model that is both efficient and compact is mounted on the heating apparatus. Steel makes up the combustion chamber’s walls, which are covered in a material that can withstand heat.

This component on a turbocharged gas column is divided into two parts:

  1. A plate heat exchanger for the selection of heat and gas combustion products using convection (similar to a boiler room).
  2. The lower part is a box made of thin-leaf copper with a glue pipe on top. In fact, this is the body of the furnace chamber. He absorbs radiant heat from hot smoke gases.

Usually, the overheating sensor/boiling water is installed on the pipe at the intersection of two sections of the heat-expenditure apparatus.

Thermal insulation does not protect copper cases. The gas column warms up quickly during operation and can transfer some of the heat to the front panel. As a result, the paint on the facade of inexpensive turbocharged column models typically darkens and the copper acquires an oleum-like brown layer.

Our basic premise in this guide to heating and insulation for your home is straightforward: efficient heating systems and appropriate insulation work together to create a cozy and energy-efficient living environment. It is essential to comprehend the principles underlying turbocharged gas columns without chimneys, regardless of your climate preference—warm or cool. These systems provide a practical and economical means of heating your house, but selecting the best one requires taking size, effectiveness, and safety features into account. Choose a turbocharged gas column that satisfies safety regulations and meets your needs to experience dependable heating without having to deal with the inconveniences of a conventional chimney.

How to calculate power

You need to know the temperature and hot water consumption in addition to possessing a passport on the model of a turbocharged column in order to compute the necessary thermal power of the hotel apparatus.

First, you must select a specific kind of gas heater from a single manufacturer. The second requires certification—a turbocharged column. The company reports the productivity of a specific type of type in thermal power with a given water flow and the heating of the water flow to 25 o in a passport or quality certificate.

It is vital to factor in the proportion of a drop or increase in power for its flow rate and fever in order to calculate the intended heat production.

For instance, the "ATON VPG-20 Turbo" gas turbocharged column has a thermal power of 20 kW and performs at 10 l/min. 2.25 m 3 of gas can be used at most per hour.

2.25 cubes of gas per hour are needed to heat the house’s water, which is excessive even though this model ranks highly for energy efficiency. 90% efficiency is 2% higher than that of the Chinese Ariston.

There is enough hot water volume at a level of 6 l/min, a maximum of 10 l/min, optimally – 8 l/min, when heated from 15 ° C to 40 ° C, for household needs, dishwashing, washing, and the soul. It turns out that a minimum of 16 kW of power is required for 8 liters. However, the result is 18 kW when the well water is heated from 9 °C to 40 °C.

Types of columns

Generally, there are two types of turbocharged columns available: automatic and semiautomatic. In the first example, automation modulates the flame in a closed burner to maintain a constant water temperature at the tap’s exit. The electronic control board and sensor system measure the water consumption (pipe pressure) and modify the burner device’s thermal power accordingly.

Consequently, the smoke exhaust’s productivity. This is handy because, unlike many old Soviet water heaters, the turbocharged column will never boil and won’t drive cold water.

Unlike the machine gun, the semiautomatic device requires manual temperature control by turning the controller handle or using a special crane to adjust the water consumption at the column’s output.

Another category of gas nonsense columns consists of models that combine a boiler and a standard water heater. Here, a turbocharged burner warms the water instead of the gluttonous heater.

This is useful, for instance, if just ten to fifteen liters of hot water are required. It makes no sense to launch a gas column for the sake of work in under 1.5 minutes. The heat exchanger’s metal components will receive the majority of the heat. Water from the boiler is easier to obtain.

The operation of the turbocharged boiler column differs from that of a standard flow water heater. The gas burner and the valves stay blocked when the DHW crane is opened on the Moika or the washing machine until two thirds of the boiler’s hot water volume is used. The automation won’t open the gas valve, activate the turbocharged air leak, or light a burning device until after that. The water heater will automatically shut off once the boiler’s 70–100 l hot water supply has been replenished.

What should you pay attention to when choosing

The majority of turbocharged column models across various manufacturers share a similar operating principle and order. The only things that differ are in the assembly quality and individual component designs.


The gas burner’s flames are ignited in all models by an electric discharge onto the candle. This could be a tiny transformer with a tiny board for the generator or a fully functional electronic module with extra features like combustion front monitoring.

Usually running on two "finger" batteries, the first option is independent of the presence of a power grid. The vast majority of Chinese-made gas water heaters in the budget class use this inexpensive ignition scheme. Thus, even for models manufactured under license, Chinese masters transferred a straightforward solution to a new turbocharged column.

It is not surprising that the Chinese version of the turbocharged column Ariston, such as the "Marco Polo M1 10L FF," has a battery-operated ignition system in addition to the main 230V network power supply for the smoke exhaust.

A relatively high-quality turbocharged column has a separate 230 V power source that powers the ignition module, burner modulation system, and all critical sensors.


The majority of manufacturers provide efficiency data from the passport or the certificate of conformance. Official dealers or service centers can provide information about how energy-efficient a turbocharged column is.

While water heaters from the EU consistently display an efficiency of 90%, Turkish and Chinese turbocharged columns typically have an efficiency of 88–90%. With a 93% rating, the Polish Termet Aqua Comfort Turbo performs admirably.

Certain gas water heaters are not as efficient as they should be; the Ross VPG-21/10 MT device, for instance, only displays 84% efficiency. However, this does not imply that the design of this turbocharged column is flawed. Despite having a lower efficiency, it can heat water to 75 °C and above while using just 6 liters of water per minute.

The turbocharged gas heater’s diagram included design solutions to guarantee the heat exchanger’s "survival" when operating in challenging circumstances.

It goes without saying that efficiency must be considered when selecting a water heater, but it’s important to keep in mind that the quality and composition of gas have a significant impact on test results for energy efficiency. Additionally, some lesser-known manufacturers might exaggerate the qualities a little bit.

Safety system

Only two sensors are present in low-cost turbocharged gas water heater models: one for temperature (which also prevents boiling) and the other for press-start operation, which regulates the amount of air traction in the combustion chamber.

The third safety component is referred to as a gas sensor, which remains closed until a three-way valve experiences pressure from both gas and water. This set is sufficient for a turbocharged water heater to function normally in the kitchen or bathroom of a small apartment.

Additionally, more costly turbocharged speakers come with separate water freezing and boiling sensors. The first is mounted in the heat exchanger’s output pipe’s hotter location. At the signal, the gas supply is cut off when the smoke clears. The heat exchanger’s work can be increased by 20–25% thanks to the straightforward system.

When installing water heaters in rooms without heat, the freezing sensor is required. The heat exchanger and the water pipes begin to heat up when the outside temperature falls below +5 o.

Heat exchanger and body

An extra safety feature on certain models is an air sash valve or sash mounted on the coaxial chimney mount flange. They enclose the pipe’s exhaust aperture. The wings are made in a way that allows the gas-air mixture’s combustion products to rise when the pressure of the outlet gases causes them to do so. The valve shuts, stopping the turbocharged column and obstructing the furnace’s exit.

A useful tool in every way. The petal valve keeps cold street air out of the combustion chamber’s interior. Sales managers frequently inform clients that the heat exchanger cannot be defrosted by cold winter air because of the closed valve. This is accurate, but only for turbocharged models that are placed in rooms without heat.

In actuality, the petals are necessary to prevent the body from being exposed to cold air from the street, which would cause water to condense on the metal exchanger metal. Moisture traces can occasionally be discovered on wiring, terminals, and—most importantly—the water heater’s electronic boards.

Certain manufacturers produce copper exchangers with an outer surface tinned. Tin’s protective coating stops oxidation, increasing the resource.

A turbocharged column can get very hot while working. As a result, many producers cover the interior surface of the box with a thin layer of mineral wool. This is sufficient to prevent heating and to block noise.

Selecting the ideal non-chimney turbocharged gas column for your home’s insulation and heating is essential for your family’s safety and comfort. Making an informed decision starts with comprehending the fundamentals of these systems’ operation.

Think about things like the size of your living area, the amount of insulation, and the climate where you live when choosing a turbocharged gas column. An appropriately sized unit minimizes energy waste and guarantees effective heating.

Furthermore, keep an eye out for safety features like automatic shut-off mechanisms and integrated sensors that can detect carbon monoxide levels. These features assist in protecting your family members and your house from possible threats.

To guarantee your turbocharged gas column operates at its best and lasts a long time, regular maintenance and expert installation are essential. To ensure safe operation, adhere to manufacturer maintenance guidelines and hire qualified technicians for installation.

In conclusion, a turbocharged gas column without a chimney works on the basis of effective heat exchange and combustion, which makes it a practical choice for insulation and heating. You can choose the ideal unit for your house that prioritizes safety while still offering warmth and comfort by taking into account aspects like size, safety features, and maintenance needs.
