Why does the geyser pop when the water is turned on? Main reasons - Setafi

You can’t find a real master during the day with fire, and the gas column, as it turns on with cotton, never stops. Unfortunately, the problem is widespread and simply does not interest experienced professionals - they have more important things to do. But what are we to do? That's right - fix the problem yourself. In this article, we will explain why the geyser pops loudly when turned on and how to deal with it.

Why the geyser pops - it's all about the design

Now we will analyze the principle of operation of the installation and its spare parts, so that it is clear: what to turn, where to turn and how to do everything right.

Inside each gas burner there is: a thermal heater (or copper coil), a gas boiler and several sensors to adjust the temperature, degree of superheat and other functions. Also, 2 water pipes are connected to the column: one for cold water (at the inlet) and the other for hot water (at the outlet to the mixers). The principle of operation of all columns on gas is as follows:

• after the cold liquid enters the boiler, the safety valve is activated and the gas is released outside;
• the igniter (electronic, mechanical, etc.) is activated and the burner ignites;
• as the fuel burns, the copper coil heats up. The whole procedure is controlled by sensors.

This is how water is heated in the coolant. The processed gas and steam are sent through a separate ventilation system, and the operating temperature is adjusted using a special thermostat located on the control box of the unit.

Why does the gas water heater turn on with cotton - the most popular problems and their possible solutions

The reason for pops when turning on the gas column almost always stops at one thing - an excessive amount of gas accumulates before ignition. But there are a lot of problems why this happens. Let's deal with individual situations, why the geyser bangs when turned on.

Lack of traction

It's simple, the main thing is to know basic physics (at the school level). When a gas boiler heats up its fuel for water, its residue or excess is discharged through the vent nozzle. Usually this is not difficult, and the column itself copes with the task.

In cold weather, everything seems different - the decomposition products of gas and oxygen are already cold, not yet reaching ventilation. When cooling, they remain below, right in the column body, and the combustion products (in the form of soot and burning) actively settle on the chimney.

Also, an active accumulation of garbage from the street can become a problem. You can clean it yourself or call a utility service. Therefore, the geyser pops when turned on and this does not stop.

We offer you a great way to check the draft in your boiler yourself: light a match and bring it to the chimney. When the thrust is normal, the flame of the match deviates to the side or it may go out. The fire stands straight, like a soldier on a parade ground - there is no traction at all, and an inspection must be carried out.

Very often, the geyser ignites with cotton when an active hood and compressor are placed nearby. When the column is in operation, it can accidentally "grab" the exhaust gas. In this case, always turn off the hood while the calorifier is in operation.

Also, weak draft is affected by the lack of ventilation of the room (all windows are closed), especially for metal-plastic inserts. The room simply does not get enough oxygen, which is so necessary for the combustion of gas. Open the window or make a small ventilation near the column - the device will work like clockwork.

Reason 2 why the geyser pops when the water is turned on - the batteries are corny

If you have been using an electronic ignition column for a long time, then you should definitely know that batteries are used for the igniter. This is much more profitable than leading to combustion with mechanical toggle switches. It is enough to replace the batteries often - and everything will be in chocolate.

If the battery is new, then it has enough energy for a quick ignition. Over time, the duration of the plant of the system increases, but you can’t say anything to the gas - it is already carried out to the copper coil. In just a couple of seconds, so much gas is accumulated that when it is ignited, it bangs.

If you open the hot water faucet and the boiler does not work, you need to change the batteries. After that, in 90% of cases, the column continues to work actively and does not give problems.

We recommend getting rid of cheap batteries, as they do not hold their charge at all. It is better to buy batteries that can be recharged and from a more expensive segment. You will be surprised how much the productivity of your device will change.

The holes of the burner itself are clogged - reason number 3

This is another favorite problem, why the geyser pops when water is connected. If you definitely notice uncharacteristic noises or if the water almost does not warm up, disassemble the column and clean the burner holes with a thin wire. Nothing needs to be dismantled.

It will also be easy to clean the base of the burner - take a soft brush and wipe the part. After that, the boiler will work like clockwork. This is what late maintenance of the device does. And it doesn’t matter if it’s a burner or a TV, you always need to take care of the equipment.

It is also worth remembering that without proper knowledge, experience and tools, it is better to do nothing at all. Entrust the task to a professional. Well, if it is not there, follow our instructions and do everything very carefully and step by step.

Why does the geyser boom loudly at startup - less common moments

We are done with the highlights. But there are others that will be found in one person out of ten - they, too, are worth touching on a little. Of course, this situation needs to be resolved as soon as possible, the better:

• The spark plug is in the wrong place. When the burner is running for a long time, the spark may be knocked down a little, and it will not reach the fuel. Solution - open the case of the device, find the candle, unscrew it and place it closer to the burner.
• Poor fuel quality. This problem happens regularly when gas with impurities is passed through pipes. You can't do without cotton. You can ask your neighbors if they use gas appliances: if the problems are identical, then your work ends there. Well, you have to wait for the supply of normal fuel.

Deformation of the device case. The steel case is sometimes not as strong as we would like. Especially when exposed to a burner. You can fix the bends yourself, just do not overdo it by arching the dents.
