Geysers AEG: reviews, overview of models, specifications

The AEG gas water heater is a product belonging to one of the most famous German brands. All modifications have one circuit diagram, which today the developers considered as close to perfection as possible. The devices are designed to meet any household needs of the owner associated with obtaining hot water. And most importantly, German water heaters, unlike 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 Us

Allgemeine Elektrizitats-Gesellschaft – AEG for short, a company founded by the German engineer E. Rothenau in 1833. The logo design was invented in 1896. Since 1909, the company was headed by the Russian inventor M. Dolivo-Dobrovolsky, who created a three-phase transformer. Since 1994, AEG’s home appliances department has been merged with Electrolux. Today the concern’s headquarters is located in Germany, and its wholesale base is in Belgium. The company has offices all over the world. This is the largest German brand that sells household appliances on the world market.

Advantages of AEG columns

The manufacturer does not need to praise the product – AEG products have long been known in Europe and beyond. The equipment of this brand is an example of safety, quality and economy. Plus an elegant stylish design that competitors can envy. Features and benefits of a technical nature:

• Thanks to modeling burners, there are no temperature fluctuations at the outlet – they change the intensity of the flame depending on the pressure in the water supply pipes.
• Reliable security system. The developers have provided several levels that exclude the occurrence of dangerous situations. Help to avoid dangerous situations:

– draft sensor (from overheating of the upper part of the device);

– 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 activated, cut off the fuel supply.

• Fuel consumption regulation. Operates without reconfiguration in the gas pressure range of 13-20 mbar.
• Combined armature. This unusual design solution allows you to solve the most common malfunction that occurs with such devices – a 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 not to lose the heating rate.
• Automatic ignition, ensuring the completeness of combustion of the incoming fuel.
• Temperature controllers 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. Compactness, simplicity of the device.
• Cumulative. The principle of their operation is similar to flow analogs, the difference is the storage capacity. They cost a little more than flow ones.

By type of combustion chamber are:

• With open. Works when connected to a chimney. Combustion products are discharged by natural draft.
• With closed. A ventilation turbine is installed that removes exhaust to the outside.

Models may 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 water intake points the device can serve. For modest consumption, 18-19 kW is enough. Based on the involvement of several points of water consumption, you need to choose a model from 24 kW.

Principle of operation and design

Structurally, AEG water heaters do not differ from their competitors. When the user opens the tap, the reducer acts on the valve, gas flows to the burner and ignites it. Heating starts. She moves along the serpentine. The output is a hot stream. When the water supply tap is closed, the valve assumes its original position, the flame goes out. Devices with an open combustion chamber are called atmospheric. They consist of:

• metal housing;
• burners;
• lighter;
• heat exchanger;
• copper coil;
• automatic gas supply valve;
• water reducer;
• piezo ignition systems;
• branch pipes supplying pipes for gas and water supply;
• chimney and flue system.

Turbocharged models – with forced exhaust exhaust, have design features:

• Modulating type of burner – can change the strength of the flame automatically.
• The fan, controlled by the electronic unit, pumps air.
• Auto-ignition – provided by batteries, hydro generator or mains.
• A sensor that controls water heating. The maximum value is 60-70⁰С and depends on the model.

Classic malfunctions and their elimination

Do-it-yourself repair of gas equipment is possible only if the breakdown is insignificant. Before any intervention in the apparatus, it is necessary to familiarize yourself with the instructions – it is not enough to be able to use it, you need to delve into the principle of operation and design. If the malfunction is serious, entrust its elimination to the service center. The most common problems:

• Column does not light up. The probable cause is a breakdown of the ignition system or a clogged igniter. It needs to be dismantled and repaired or cleaned. It is better to entrust this to a specialist. You can independently eliminate the lack of traction associated with a clogged chimney.
• Burner damping. Probable causes – the temperature sensor or the emergency shutdown system is faulty. What is it connected with? Perhaps – a factory defect or a violation of the operating rules that provoked a 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 poor pressure. Causes – the burner runs idle, causing the heat exchanger to overheat. It needs to be cleaned or replaced. Details about the heat exchanger on the page “Heat exchanger for geysers, repair, cleaning«.

Independent disassembly and cleaning of the equipment is strictly not recommended by the manufacturer and specialists in its repair and adjustment. Unless you can change the battery without the help of specialists, entrust the rest to the service center.

If the auto-ignition column does not light up?

• Start by checking the performance of the batteries from which the device is ignited.
• 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 settings?

• Power. The relay located on the control panel (marked with the “flame” icon) regulates the gas flow. To increase the fuel supply, you need to turn the knob counterclockwise, to decrease – vice versa.
• Temperature. It is adjusted with a regulator marked accordingly – “thermometer”. To increase heat and decrease pressure, turn the regulator clockwise.

Important! The valve on the cold water riser must always be in the 100% open position. It is forbidden to adjust the fluid pressure by turning this valve.

If the device is not in use?

• Shut off the gas.
• Take the batteries out of the compartment.
• Close the cold water shut-off valve.
• Set the temperature control relay to the “minimum” position.
• Open the gas valve.
• Drain the liquid from the heat exchanger.

Maintenance

In order for the equipment to work flawlessly, it is necessary to clean it annually, and if necessary, change parts that have failed. We recommend that you use original spare parts for replacement, otherwise you may void the warranty. During preventive maintenance, check and perform:

• How does the exhaust system work.
• Burner cleaning. Nozzles are cleaned with a brush.
• Cleaning the heat exchanger.
• The condition of the electrodes – ignition and control.
• Tightness of gas joints with a soapy solution.

How to turn on a column with piezo ignition?

Turning on begins with turning the gas supply regulator – drowning it, and turning it clockwise to the “asterisk” mark. Having put the handle in this position, press the piezo ignition button with a hold of 7-8 seconds – until a steady flame appears.

When you turn it on for the first time or after a long idle time with the fuel supply turned off, they act differently: the relay is turned to the minimum position until it clicks – so that the entire pipe is filled with the gas mixture. You need to wait 20-25 seconds. Then put the regulator in the “asterisk” position and turn on the piezo ignition. After waiting 15 seconds – for the protective valve to work, set the desired mode by adjusting the gas supply.

Reviews

GWH 11 ERN: Gleb Yu., Naberezhnye Chelny

The thing is not for a long time. Five years later, it leaked in two places at the same time. If the pressure is small, this model will not work – it does not light up. I had to change the pipes, only then they were able to wash normally. Cons – noisy, even expensive batteries have to be changed very often. Cheap ones sit in a couple of days. When you turn it on, there is a crackling sound and boiling water flows for a couple of minutes – you have to stand and wait for a normal one. Not designed for two points – low-power. On the plus side, it looks good and the controls are comfortable.

GWH 14 RN: Alina R., Samara

Connected after three years of inactivity in the package. But fired up with no problem. 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 control. If you open another tap, the water practically does not lose heat. Light ignition. Cons – the wick burns all the time. There is no heating indicator. Plus – not afraid of splashes, moisture, 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 ideal for everyday use. The appearance of problems is usually associated with a violation of the rules of operation and physical wear of parts. Due to the presence of an extensive service network, maintenance, adjustment and repair of AEG speakers does not cause any difficulties.
