AEG gas water heater - products belonging to one of the most famous German brands. All modifications have one circuit diagram, which for today, the developers considered as close to perfection as possible. The devices are designed to meet any household needs of the owner associated with the production of hot water. And most importantly, German water heaters, unlike their Chinese counterparts, not only heat water: they are able to maintain its temperature constant - without this, using the services of a column cannot be comfortable.
About company
Allgemeine Elektrizitats-Gesellschaft is abbreviated as AEG, a company founded by German engineer E. Rothenau in 1833. The logo design was coined in 1896. Since 1909, the company was headed by Russian inventor M. Dolivo-Dobrovolsky, who created a three-phase transformer. Since 1994, the AEG home appliance department has been merged with Electrolux. Today, the headquarters of the concern is located in Germany, and its wholesale base is in Belgium. Representative offices are available worldwide. This is the largest German brand selling household appliances in the world market.
Advantages of AEG columns
The manufacturer does not need to praise the goods - AEG products have long been known in Europe and beyond. The equipment of this brand is an example of safety, quality and profitability. Plus an elegant, stylish design that competitors can envy. Features and advantages of a technical nature:
- Thanks to the modeling burners, there are no temperature differences at the outlet - they change the flame intensity depending on the pressure in the water pipes.
- Reliable security system. The developers have provided several levels that exclude the occurrence of dangerous situations. Avoid dangerous situations:
- traction sensor (from overheating of the upper part of the apparatus);
- thermocouple (from the spread of gas in case of accidental extinction of the flame);
- hydraulic valve (from overheating of the device).
The equipment is equipped with special safety valves - if the burner goes out during operation, they, when triggered, cut off the fuel supply.
- Fuel consumption regulation. It works without reconfiguration in the gas pressure range of 13-20 mbar.
- Combined fittings. This unusual design solution allows you to solve the most common malfunction that happens with such devices - to leak at the pipe connection.
- The formation of scale in the tubes of the heat exchanger is prevented due to special turbulators. The absence of scale allows you to not lose the heating rate.
- Automatic ignition, ensuring the completeness of combustion of the incoming fuel.
- Temperature controls are provided.
- Gas-fired water heaters are more economical than boilers. Blue fuel is the most profitable energy resource today.
- Compactness. Easy to place in the cramped kitchen.
Types of geysers
There are two designs of AEG water heaters:
- Flowing. Low cost price. Compactness, simplicity of the device.
- Cumulative. The principle of their action is similar to flow-through analogues, the difference is the storage capacity. They cost a little more flow.
By type of combustion chamber there are:
- With open. It works when connected to the chimney. Combustion products are diverted by natural draft.
- With closed. A ventilation turbine is installed that removes exhaust emissions.
Models can also differ in power, color, design.
How to choose power?
The main parameter when choosing a water heater is its heat output. The volume of heated water depends on this indicator. The smaller it is, the fewer points of water intake can serve the device. For modest consumption, 18-19 kW is enough. Based on the use of several points of water consumption, you need to choose a model from 24 kW.

Principle of Operation and Design
Structurally, AEG water heaters are no different from their competitors. When the user opens the valve, the reducer acts on the valve, gas enters the burner and ignites it. Heating starts. She moves along the coil. The output is a hot stream. When the water supply tap is closed, the valve takes its initial position, the flame goes out. Devices with an open combustion chamber are called atmospheric. They consist of:
- metal case;
- burners;
- pilot light;
- heat exchanger;
- copper coil;
- auto gas valve;
- water gear;
- piezo ignition systems;
- branch pipes for gas and water supply pipes;
- chimney and exhaust systems.
The turbocharged models - with exhaust exhaust, have design features:
- Modulation type of burner - can change the flame power automatically.
- A fan controlled by an electronic unit blows air.
- Auto-ignition - is provided by batteries, a hydrogenerator or an electrical network.
- A sensor that controls the heating of water. The maximum value is 60-70⁰С and depends on the model.
Classical malfunctions and their elimination
Do-it-yourself gas equipment repair is possible only if the damage is insignificant. Before any intervention in the device, you must familiarize yourself with the instructions - it is not enough to be able to use it, you need to understand the operating principle and design. If the malfunction is serious, entrust it to the service center. The most common problems:
- The column does not light. The probable cause is a breakdown in the ignition system or a clogging of the igniter. Here you need disassembly, followed by repair or cleaning. It is better to entrust a specialist. Independently, you can eliminate the lack of draft associated with clogging of the chimney.
- Burner attenuation. Likely causes are a temperature sensor or an emergency shutdown system. What is the reason for this? Perhaps - a factory defect or a violation of the operating rules that provoked the breakdown. Another option is poor cooling due to improper installation of the device. In any situation, the intervention of specialists is required.
- No hot water or bad pressure. Reasons - the burner is idling, causing the heat exchanger to overheat. It must be cleaned or replaced. Details about the heat exchanger on the page "Heat exchanger for gas water heaters, repair, cleaning".
Self-disassembling and cleaning of equipment is strictly not recommended by the manufacturer and specialists in its repair and commissioning. Unless you can change the battery without the help of specialists, entrust everything else to a service center.
If the auto-ignition column is off?
- Start by checking the performance of the batteries from which the device is fired.
- Open the gas valve.
- Set the power control relay to maximum.
- Open one of the hot water taps. Doesn't turn on? Reopen the valve after 20 seconds. Check for flame.
How to adjust the parameters?
- Power. Using the relay located on the control panel (marked with a “flame” icon), the gas flow is regulated. To increase the fuel supply, you need to turn the knob counterclockwise, to decrease - on the contrary.
- Temperature. It is set with the regulator with the corresponding mark - “thermometer”. To increase heating and reduce pressure, the regulator is turned clockwise.
Important! The valve on the cold water riser must always be in the position - it is 100% open. It is forbidden to adjust the fluid pressure by turning this valve.
If the device is not in use?
- Block the gas.
- Remove the batteries from the compartment.
- Close the cold water shutoff valve.
- Set the temperature control relay to the “minimum” position.
- Open the gas valve.
- Drain the fluid from the heat exchanger.
Maintenance
In order for the equipment to work flawlessly, it is necessary to clean it annually, and if necessary, to replace parts that have failed. For replacement it is recommended to use original spare parts, otherwise you may lose the warranty. During preventive maintenance, check and perform:
- How does the exhaust system work?
- Burner cleaning. The nozzles are brushed.
- Heat exchanger cleaning.
- The state of the electrodes - pilot and control.
- Tightness of gas joints with a soap solution.
How to turn on the piezo ignition column?
Switching on starts with turning the gas supply regulator - drowning it and turning it clockwise to the “asterisk” mark. Putting the handle in this position, press the piezo ignition button with a hold of 7-8 seconds until a steady flame appears.
The first time you turn it on or after a long period of inactivity with the fuel supply turned off, they act differently: turn the relay to the minimum position until it clicks — so that the entire pipe fills with the gas mixture. You need to wait 20-25 seconds. Then put the regulator in the “star” position and turn on the piezo ignition. After waiting 15 seconds - so that the protective valve works, set the desired mode by adjusting the gas supply.
Reviews
GWH 11 ERN: Gleb Yu., Naberezhnye Chelny
Thing is not for a long time. Five years later, flowed simultaneously in two places. If the pressure is small, this model will not work - it will not light up. I had to change the pipes, only then could wash normally. Cons - it makes noise, even expensive batteries have to be changed very often. Cheap sit in a couple of days. When you turn it on, a crack sounds and a couple of minutes boiling water flows - you have to stand and wait for normal. Not designed for two points - low power. From the pros - it looks good and the control knobs are comfortable.
GWH 14 RN: Alina R., Samara
Connected after three years of downtime in the package. But ignited without any problems. It works flawlessly. Heats well. There are 2 modes - maximum and economy. In an ordinary apartment there is even a lot of it - quite enough for several consumers. If there is one bath and a kitchen, then even in economy mode its power is too much. Plus - automatic temperature. If you open one more tap, water practically does not lose heating. Easy ignition. Cons - the wick burns all the time. There is no heating indicator. Plus - it is not afraid of splashes, humidity, it can be installed in the bathroom.
Gas water heaters from AEG are simple and reliable, easy to operate. These are worthy representatives of European quality. Safe and inexpensive equipment is ideal for everyday use. The appearance of problems is usually associated with a violation of the operating rules and physical wear of parts. Due to the presence of an extensive service network, the maintenance, commissioning and repair of AEG speakers does not cause any difficulties.
