Recommendations for choosing a unit
When choosing a column, you need to take into account many parameters; let’s outline the main ones.
Performance, i.e. the ability of the device to produce a certain volume of hot water prepared for supply for tapping in a specific unit of time.
Some owners encountered an unpleasant phenomenon. When two taps were opened at the same time, for example in the kitchen and in the bathroom, there was not enough water.
This occurs due to insufficient performance. For the situation described, a device that produces about 10 l/min is suitable.Most of the geysers from the presented reliability and quality ratings correspond to this level in terms of performance.
Camera type. Devices equipped with a closed chamber are usually several times more expensive than conventional devices with an open chamber. The latter can only be installed in houses where a chimney is already provided for this purpose.
In closed chambers, exhaust gases are forced out thanks to a built-in turbine. It makes sense to spend money on such an expensive purchase only when there is nothing else left, because it is most convenient to use gas to heat water.
Method for regulating gas consumption. The most convenient devices in this regard are those equipped with a device for simulating a burner flame. In such a model, it is enough to set the appropriate settings once, and the water temperature will remain comfortable, regardless of the pressure or changes in the temperature of the cold water in the system.
But devices with this function are quite expensive. Those on a budget will have to choose from models with smooth or stepped adjustment.
You will need to set the settings almost every time you use hot water. Typically the temperature is raised and then adjusted by adding cold water to the flow.
Device dimensions and installation method. The most popular models are usually small, wall-mounted and vertical. If the location for the column has already been selected, you should familiarize yourself with the manufacturer's requirements. Perhaps the device cannot be installed close to a cabinet, wall or other objects; a certain clearance must be provided.
Additional factors. It is necessary to remember such points as the compatibility of the selected model with existing communications to which it will be connected, as well as the availability of service centers and features of warranty obligations.
Problems with installation and warranty are typical for some imported devices.
Additional recommendations for choosing a geyser are described in this article.
Effective use of the device
When operating gas units, two serious dangers must be taken into account, such as the possibility of poisoning by gas fuel processing products and explosion. That is why you should never neglect to carefully study the operating instructions and comply with all its requirements.
To ensure sufficient draft for the normal functioning of the column, care should be taken to ensure a constant supply of air to the room equipped with the device. Plastic windows reliably block the path of air flow.
For the column to work properly, it makes sense to arrange a suitable option supply ventilation. Before turning on the column, it is mandatory to check the traction.
It is best to use thin paper for this rather than matches or a lighter. If gas accumulates inside the housing due to a breakdown, it may explode.
It is important to understand that unauthorized geyser installation is fraught not only with fines, but also with much more serious consequences.
You cannot repair a broken speaker yourself or make your own changes to the design. This may lead to a possible gas leak and subsequent explosion.
Over time, the heat exchanger becomes clogged with scale and has to be clean periodically.
In order for this process to occur as slowly as possible, you need to set the heating temperature correctly. The higher it is, the more scale there is. The maximum recommended value is 55°C.
Some speakers do not turn on immediately because there is no water inside. First, open the water tap to fill the circuit, and then light the gas.
It doesn’t hurt to drain some water first and remove any accumulated air.

Tips for choosing the right model:
The range of speakers from different manufacturers is quite wide. You can always choose a productive unit at a suitable price. If the rules established by the manufacturer are followed, the heater will operate for more than ten years without breakdowns or problems.
Share your personal experience in choosing and operating a gas water heater. You can ask questions, leave comments and add photos in the form below.
Gas water heaters are very convenient; after all, their operation is much more economical than using electric boilers. We've had the Mora Vega 16E for about a year; overall it's not bad, but, of course, not without its drawbacks. For example, in the evening, when the water pressure is not as strong as during the day, it may not turn on. Perhaps it's a matter of old communications. I had to tinker with the connection due to the inconvenient, ill-conceived design. Well, and the most important thing for me, which the manufacturer did not mention, is that you cannot add cold water when hot water is running in order to achieve the desired temperature.
There are a lot of negative reviews on the Internet about your Mora Vega.They complain about low reliability - two or three years and problems begin with the heat exchanger, then with something else. And it's not cheap.
We have a Vaillant gas water heater in our apartment. It was installed a long time ago, since the house is old and there is no provision for hot water. Now we want to connect the boiler because it will cost less. We have electric ignition in the column; it turns on in 2 movements. Just to save money, you have to turn it off and turn it on again if necessary. There is a water temperature regulator, but poor pressure in the tap is a significant disadvantage.
