The battery in a gas water heater is used for the sole purpose of igniting gas using a spark. Despite the low voltage and power of the batteries, the formation of a spark is carried out by the electrical system, in which the voltage increases to such values that the air is pierced by a discharge.
Considering the relatively large energy consumption during ignition, only products with certain parameters can be used for installation in water heating geysers.
The principle of operation of a battery-powered speaker
All water heaters work the same way - in a short time they need to heat running water in a heat exchanger to a given temperature. Differences appear in the ignition and protection systems.
In battery-powered dispensers, a spark is created automatically when the hot water valve is opened. The energy to create a spark is taken from two D-type batteries.
The wick in a gas water heater does not burn constantly - it goes out immediately after turning on the main burner. The column has a water flow sensor. When the tap is opened, it is triggered and closes the electrical circuit, supplying voltage to the actuators.
As a result, the gas supply valve to the main burner opens and a spark is formed. The gas begins to burn and heats the running water. When you close the tap, the water flow stops. The water flow sensor cuts off the gas supply.
All speakers must be equipped with the following sensors:
- determination of chimney draft;
- pressure control in the supply pipe;
- presence of flame.
Additionally, a maximum flow water temperature sensor and an overpressure safety valve can be installed.
Error E8 - no traction
The column turns off after 2..5 minutes of operation. Restarting becomes possible only after cooling down - 2..3 minutes.
Reason #1.
Lack of draft in the chimney. Clean the chimney.
Reason #2.
Soot on the heat exchanger. Increased accumulation of soot on the heat exchanger, which prevents the passage of carbon monoxide into the chimney. To resolve the problem, the column must be serviced.
Reason #3.
The traction sensor is faulty. The traction sensor works to break. Over time, the sensor becomes very sensitive to vibrations and may turn off the column during heating. Therefore, if this error occurs, the sensor will be checked for functionality.
What batteries are used in speakers
For full operation, the gas water heater requires power sources with a total voltage of 3 volts. Therefore, batteries for water heaters stand out from the more familiar finger and mini-finger modifications. These are thicker Class D “barrels” that produce a voltage of 1.5 V each.
In fact, there are two types of batteries on the market: D-LR20 and D-R20. They differ from each other in price and “filling”: inside the battery there may be salt or alkali.
D-R20 salt batteries are confidently losing ground, which is more of a plus than a minus. Cheaper power supplies are notorious for extremely fast discharge rates. Therefore, even the low attractive price does not make the purchase of the D-R20 worthwhile.
Alkaline alkaline batteries D-LR20 are more expensive, but do not require as frequent replacement, working properly for up to six months. A salt power source will last a couple of weeks at best.
To save as much money as possible on routine battery replacements, you should purchase rechargeable batteries. Used batteries and accumulators should not be disposed of with household waste, as power sources require special disposal.
Comparison of the appearance of batteries of different classes.
Class D batteries look really impressive compared to power sources of other categories. For gas water heaters, nickel-metal hydride battery versions - NiMH D/HR20 - are best suited. However, before installation, you should make sure that the voltage in each battery is 1.5 V.
If operating standards are observed, such batteries will last 5-6 years, gradually losing their capacity. But it is worth remembering that you will have to buy a battery charger separately.
How to choose power supplies
The safest option to avoid making a mistake in choosing a product is to go to a store with old batteries and buy batteries with similar parameters.
When choosing, be sure to take into account the manufacturer’s recommendations and pay attention to the appearance of the product when purchasing it. However, this approach may not protect you from purchasing low-quality units.
Additionally, you should pay attention to the following nuances:
- compliance with the expiration date;
- packaging integrity;
- absence of abrasions and mechanical damage on the case;
- correct shape of the power source.
The abundance of counterfeits on the market and storage of products in inappropriate conditions without maintaining the correct temperature conditions significantly affect the service life of batteries and accumulators.
Power supplies purchased at the nearest crossing are unlikely to be certified and reliable products. Therefore, purchase batteries from official offline and online stores. After all, the use of any damaged battery is fraught with fires and damage to equipment.
Why do they sit down quickly?
If we talk about why batteries in a geyser are quickly consumed, the main reason is usually not very high-quality batteries. Speakers produced today usually use two D-type batteries with a voltage of one and a half volts. If cheap batteries made in China are installed there, they can last two or three weeks maximum.
The principle of operation of batteries in the case of using such equipment is simple and consists in the fact that when the device is turned on, the batteries are activated and send current to the control unit. And now he gives a signal to the incendiary candle, which produces a spark in the ignition block. Under pressure, the valve opens and gas begins to flow into the burner. Ignition is carried out in a similar way.
If the batteries run out, the spark will begin to produce unstably or the column will stop turning on. In a number of models, this can be understood by flashing a special LED, which is designed specifically for this.
But there can be several reasons for the rapid discharge of batteries:
- high humidity;
- incorrect operation of the ionization sensor;
- displacement of the electrode responsible for ignition;
- problems with the control unit;
- low quality batteries.
Now let's talk about each reason in as much detail as possible. Increased humidity can be observed when installing the speaker in the bathroom. Moisture and steam simply begin to settle on the spare parts, which prevent normal ignition from occurring. Contacts begin to oxidize, and corrosion appears on parts. The room should be cleaned and ventilated more often, and a good ventilation system should be installed.
If we talk about the incorrect operation of the ionization sensor, then such a sensor is responsible for the presence of a flame in the burner. If it has moved too far to the side, then the spark will take a long time to be produced, and the charge energy will simply be wasted. In this case, you should look at where the sensor is located and correct its location if necessary. It may also simply become clogged due to soot. When gas enters, the spark should immediately ignite and transform into fire. If this does not happen, we are talking about the displacement of the ignition electrode, then you can try to move the electrode closer to the burner.
Speaking about problems with the control panel, we note that the batteries are responsible for the stable operation of the electronic module. If it has any problems, it will require more energy to operate than usual. If this is the problem, then you should remove the cover and inspect the unit. After this, we disconnect the wires leading to it, open it and check all the parts for scorch marks. If there are no visual problems, then you should call a specialist.
We have already written about low-quality batteries above. If we talk about what batteries are needed, then it is better to follow the recommendations given by the manufacturer in the instructions for the gas water heater. It is best to use the alkaline version of LR20 from manufacturers such as Energizer and Duracell.

How to change batteries in a speaker
In instantaneous gas boilers, a special place is provided for batteries. This is usually a plastic container located at the bottom of the case. There is a hinged lid with a locking lock. The batteries should be inserted into the speaker after it is turned off. To this end:
- open the lid;
- carefully pull out the barrels, slightly bending the plastic clips;
- install new batteries, observing +/- polarity;
- close the lid and do a test run.
To extend the life of the batteries, if you do not plan to use the speaker, you can turn it off using a special switch at the bottom of the case. The button disconnects the ignition unit from the batteries.
Installation of new parts
Here is the sequence of replacement steps for columns. The work is carried out almost the same for all brands of equipment.
First, turn off the gas and water supplies. You will find a plastic block at the bottom of the case. Open its lid by turning the handle counterclockwise.
However, not all models are so simple. There are different types of boxes:
- On latches. When you open the lid you will find vertically arranged elements. They are held in place by an L-shaped latch. Move them aside and replace them. Then close the lid and turn the handle.
- Pull-out box. This is found in the Neva Transit model. Only the outer wall of the box is visible from below, the rest is hidden in the body. To dismantle, press the wall until you hear a click and the contents will slide out into your hand. Make a replacement and put the block back. It is important not to confuse the installation side and polarity.
Is it possible to transfer the speaker to a power supply?
To convert a battery-powered speaker, you need:
- Purchase a power supply with parameters 220V/3V/500 mA.
- Buy two female-male connectors.
- Lead the two wires located inside the compartment for the battery box downwards from the device body. On them you will see the “mother” halves and markings.
- If the wires are not marked with different colors, mark which one belongs to “+” and which one belongs to “-”.
- Cut off the plug from the power supply, separate the wires and solder the male halves to each.
- Connect the halves of the connectors taking into account the polarity.
- Plug the unit into a power outlet.
