Types of ignition modern geysers
The classification of gas water heaters by type of ignition divides these devices into three groups:
- manual;
- piezo ignition;
- electronic.
The first option has long been considered a thing of the past and is not manufactured today on a production scale.Piezo ignition works like a lighter, creating a spark through mechanical force. Geysers with this type of ignition start working after pressing the button and triggering the piezoelectric element that ignites the igniter. As a rule, a temperature regulator is located on the front panel of such devices. Setting the required level of water heating allows you to carry out water procedures within a few seconds after pressing the corresponding key. At the same time, gas consumption in such models is noted to be an order of magnitude higher than in electronic counterparts. This fact is argued by the fact that even after ignition, the igniter does not stop burning.
Devices, the design of which involves electronic ignition, are able to automatically operate after turning the handle by the consumer. The burner responds to the turn of the valve on the tap. Gas is consumed in this case only if a column is used. Models are representatives of the latest developments of technologists of this subject of production. Ignition of the electronic type is also divided into two subspecies: battery-powered (functions due to a convenient, replaceable and affordable source); hydro turbine (works due to the power of an electric generator, is the best option for households, the water pressure in the pipes of which is at least 0.35 atm).
1 BOSCH WTD 27 AME
The best power indicator among instantaneous gas heaters is the Bosch WTD 27 AME model. The column differs in the compact sizes, stylish design and big productivity. In addition to being used in large houses and apartments, the unit is also suitable for providing hot water to sports clubs, hotels, cafes, car washes, etc.Thanks to the electronic control system and backlit LCD monitor, it is convenient to set up the device and monitor its readings. The device has an overheating sensor that allows you to save gas. The water valve is equipped with an electric drive. The geyser is suitable for providing hot water to several points of water intake, this allows you to make a modulating burner.
In the reviews, ordinary inhabitants and experts agree that the model is best gas stove flow type. It can be set up once and not approach the device for a long time. Of the shortcomings, only the high price stands out.
Acoustic Energy 301
When developing the 300 series, the designers sought visual minimalism. All small details such as screws, grill mounts are excluded from the appearance. The front wall of the speaker is finished with a black rubber-like coating that blends in color with the cones of the emitters. The finish of the speakers is also minimalist - black or white lacquer. The 301 features a signature 28mm fabric dome tweeter and a traditional, well recognizable mid/bass driver with a 110mm bent, heavily anodized aluminum cone. This speaker is a distant legacy of the legendary AE1 monitors.
Bookshelf acoustics Acoustic Energy 301
Curiously, the company decided to use a slotted bass-reflex port placed on the front panel. It was possible to save the size of the column with the convenience of its placement near the wall.
Sound The absence of any noticeable sound color allows the column to turn around and, even playing rather restrainedly, present musical compositions in an interesting way. The smallest details are clearly distinguishable, and the timbres are very close to natural.The entire frequency scale is well balanced both in terms of level and dynamics - the sound is holistic.
The intelligibility of the upper register is not bad, but it is a bit lacking for an open sound with enough air. On complex compositions, the intelligibility of musical material is reduced. At low volume, the character of the sound almost does not change.
measurements
The frequency response is very flat. The decline in the low-frequency region is uniform. Bass of medium depth. THD is quite low up to the lowest limit and practically does not depend on the volume level. The impedance is unstable.
Device and principle of operation
A classic gas water heater is a wall-mounted instantaneous water heater that runs on the energy released by burning natural gas. In the simplest configuration, such a device consists of several basic elements:
- steel body;
- Burners;
- igniter;
- Supply pipes and fittings;
- gas valve.
Scheme of a classic geyser
Before choosing a specific model of a geyser, consider the principle of operation of this unit.
When the tap is opened, water begins to circulate around the water heater circuit. Upon reaching a certain pressure in the system, the gas valve is activated, which opens the fuel supply to the gas burner. The igniter starts the process of gas combustion. Hot combustion products pass through a heat exchanger through which water circulates from the plumbing system.
As a result of this process, the water is heated and enters the water intake system, and the combustion products are discharged through the chimney into the atmosphere.
Basic selection options
To consider which gas burner to choose for a room, let's get acquainted with the main distinguishing features of heating appliances.They differ in appearance, type of combustion chamber, power, type of ignition, gas pressure in the system, different removal of combustion products and additional functional characteristics.
Types of combustion chambers
The geyser can have an open and closed combustion chamber. In the first types of equipment, the flame burns out with the air that comes from the room. For this, a fence is provided below. Combustion products are removed through a special chimney, which is in any apartment.
Columns with closed chambers use oxygen from the street to support the fire. A coaxial chimney is mounted with a water heater. As a result, the products of combustion are removed using the built-in fan. The devices are complex and expensive.
Water heater power
The next important parameter that the user should pay attention to when choosing a gas water heater is power. It depends on the performance of the device.
This characteristic shows the amount of water that the device can heat in a certain period of time.
There are three categories of units with power:
- low - 17-17 kW;
- medium - 22-24 kW;
- high - 28-31 kW.
Depending on the tasks that the device must solve, the technical characteristics of the water heating device are selected. A powerful geyser will be needed to operate several water points, models with low power, as a rule, provide hot water for a sink in the kitchen or a shower room.
Ignition type
Depending on the way the gas column is turned on, there is electronic, manual ignition and piezo ignition.Gone are the days when the wick was lit with matches. Now you can light the burners automatically or using the buttons. Let's consider each of the options.
- Battery ignition. It turns on automatically after the tap opens. Batteries are the source of energy. Their resource is enough for 3-4 months.
- Ignition from a hydraulic turbine. This type of igniter is used in expensive models. The source of energy is an electric generator. This option is suitable for those whose water pressure is more than 0.35-0.5 bar.
- Piezo ignition. With the help of a special button with a piezoelectric element, the wick is lit. Since the location of the button is inconveniently located, it is difficult for owners to use the pier ignition.

Device management
A gas water heater should be not only functional, but also convenient to use. It can be regulated, in addition to the level of gas supply, its pressure. In this case, the column will work at reduced water pressure in the tap. The presence of a liquid crystal display will make it possible to see the main parameters of the device:
- outlet water temperature;
- flame modulation;
- error codes in case of device malfunction and other parameters.
Column safety
Despite technological progress, this parameter must be taken into account when buying a geyser. How to choose a gas water heater that is safe to use? Some mandatory requirements apply to the device:
- in the event of interruptions in the supply of gas or water, the unit should automatically turn off;
- if the gas supply is resumed, there should be no leakage;
- in case of weak draft, the unit is automatically switched off.
To meet these requirements, manufacturers equip the device with special sensors.
- Ionization sensor.If the flame goes out, the system itself turns off the gas supply.
- Flame sensor. It performs the same functions as the previous device, if the ionization sensor does not work.
- The relief safety valve is designed to control the pressure of water through the pipes.
- Flow sensor. The purpose of this function is to automatically turn off the device if the tap is closed and vice versa.
- Traction sensor. Prevents people from carbon monoxide poisoning in the absence of traction.
- Low pressure sensor. Thanks to this protection system, the column will not turn on if the water pressure is low.
- Overheat sensor. The main task is to control the temperature of the water: if it rises, the equipment turns off. This additional safety feature prevents pipes from bursting.
When buying, consider the presence of all these sensors. If any of the listed devices is not present, then the column cannot be called safe.
Varieties of geysers and their device
Modern manufacturers provide the widest choice of devices with various technical and operational characteristics. All gas water heaters can be divided into two types:
- flowing;
- cumulative.
Flowing geyser (schematic diagram).
1. Traction detector; 2. Overheating detector;3. Gas burner; 4. Gas supply regulator; 5. hot water outlet;
6. Chimney outlet; 7. Collector for combustion products; 8. Heat exchanger; 9. Gas pipe; 10. Regulator of water intake; 11. Cold water outlet.
The flow geyser has a compact size due to the small gas burner and the lack of a hot water tank. It can be installed in a small room with good natural ventilation.However, such devices have a low capacity; to connect several points of hot water intake to the DHW system, you need to purchase a high-power device. These speakers are best suited for city apartments.
Accumulative gas water heaters (principal diagram)
1. Gas check valve; 2. Gas supply adjustment knob; 3. Adjustment of water temperature; 4. Gas burner; 5. Igniter gas wick; 6. Thermocouple; 7. Nozzle of the main gas burner; 8. Internal protective coating; 9. Thermal insulation of the water tank; 10. External protective casing; 11. damper;
12. Anode to prevent scale and corrosion; 13. Drain cock; 14. Cable from the draft detector; 15. Chimney base; 16. Divider; 17. Cold water supply pipe; 18. Swirl of water streams to intensify mixing; 19. Emergency relief valve socket; 20. Outlet pipe for hot water; 21. Traction stabilizer.
Storage devices are large. The volume of the tank ranges from 50-500 liters. To use hot water, it is not necessary to turn on the device every time. Effective thermal insulation of the container allows you to keep warm for a long period. The heat exchangers of the apparatus are more efficient.
Of the main disadvantages, significant dimensions should be noted, which force the installation of devices in special boiler rooms, basements or attics. In addition, the significant weight of large-volume water tanks requires additional reinforcement of floors and preparation of a concrete base. It is advisable to use such gas water heaters in cottages and private houses, where there are many points of use.

Types of geysers
With open chamber
When the firebox is open, the air that supports combustion comes from inside the room where the water heater is installed.
For example, from the bathroom, where installation is not always allowed, or from the kitchen. In private houses, as a rule, specially adapted non-residential premises with 3-fold air exchange are allocated for the column.
An apparatus of this type is equipped with an atmospheric burner and an outlet to a vertical (2 turns of 90 ° are allowed) chimney through which exhaust gases are removed using natural draft.
For apartment buildings, based on regulatory documents, it is prohibited to use the ventilation duct as a smoke duct.
Advantages:
- comparative simplicity of design;
- energy independence of a significant part of the models;
- noiselessness of work;
- big choice;
- price availability.
Flaws:
- air intake from the inside;
- the need for a chimney.
Appliances with an open combustion chamber are installed both in apartments and in private houses. For the latter, they are more suitable. At least for the reason that technical issues are easier to solve and there are fewer problems with the gas or fire service.
Closed camera
The requirements for the installation of devices with a closed firebox are relatively not so stringent - their working compartment is hermetically “sewn up”, so the air is consumed not from the interior, but from the street.
Instead of a standard vertical chimney, a coaxial horizontal chimney is used - it consists of an inner pipe through which combustion products are removed using an electric fan, and an external one designed to supply oxygen from the outside.
In such devices, the atmospheric burner is replaced by a turbocharged one. Since the air for the operation of the column is taken outside the home, such a water heater can be installed in almost any room.
Advantages:
- increased operational safety;
- possibility of installation in any room;
- high efficiency and environmental friendliness of work;
- comfort of use;
- comparative ease of installation.
Flaws:
- volatility: the fan is connected to the network;
- noise during operation;
- relatively high price.
Devices with a closed combustion chamber are installed in virtually any building. In high-rise residential buildings in some regions, a coaxial pipe is prohibited - only its separate version is allowed only with air flow through the wall.
With piezometric ignition
In devices with a semi-automatic ignition mode, there are 2 burners: one is a pilot, which operates continuously; the other is the main one, working only in the interval between turning on and turning off the tap.
When starting the water heater: the corresponding button is pressed on the front panel; candles give caviar; pilot wick ignites. After opening the DHW tap, the fire spreads to the main burner.
During the operation of the device, both heaters function, after the hot water is shut off, only the pilot one burns. This ignition option is far from economical, but in places with frequent power outages it is popular with the population.
Advantages:
- cheaper water heaters;
- energy independence;
- ease of use.
Flaws:
additional, albeit insignificant, gas consumption.
Devices with piezometric ignition are non-volatile, therefore they are installed in houses, apartments and cottages, in which power outages are a frequent occurrence. In addition, the financial losses from a constantly burning wick are insignificant.
With electric ignition
Gas in columns operating in automatic mode is supplied and ignited only after turning the tap - the rest of the time it is not consumed.
Functioning is carried out using an electronic unit that controls the ignition and combustion process.2 batteries are directly involved in igniting the gas, which need to be changed about once a year - it is with their help that the sparks necessary to form a fire are created.
Models are also produced that are switched on from the mains 220 V - in this case, an additional electronic stabilizer is purchased, which extends the life of the water heater, in particular imported.
Advantages:
- use in more modern models;
- fuel consumption is the minimum required;
- increased operating comfort.
Flaws:
dependence on electricity.
It is advisable to install devices with electric ignition in cottages and apartments, the supply of energy to which is carried out without interruptions and power surges. Battery-powered appliances are suitable for homes, regardless of the mode of electricity supply.
