Unit recommendations
Choosing a column, you need to take into account many parameters, we denote the main ones.
Performance, i.e. the ability of the device to deliver a certain amount of hot water prepared for supply to a water intake for a specific unit of time.
Some owners are faced with 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.
The compact wall model of a geyser is the most popular version of such a heater. It is small in size and fits well in almost any interior
This is due to poor performance. For the described situation, a device issuing about 10 l / min is suitable. Most geysers from the presented reliability and quality rating for productivity correspond to this level.
The small size makes it easy to find the right place for installing a gas heater. Most often, such devices are placed in the kitchen or in the bathroom
Camera type. Devices equipped with a closed-type camera are usually several times more expensive than conventional devices with an open camera. The latter can be installed only in houses where a chimney is already provided for this.
In closed chambers, forced exhaust gas removal is performed thanks to the integrated turbine. Spending money on such an expensive purchase makes sense only when nothing else is left, because it is most convenient to use gas to heat water.
The compact coaxial chimney can be mounted very simply, it helps to solve the problem of removal of combustion products and oxygen supply to the boiler of an independent heating system and hot water treatment
The method of regulating gas consumption. The most convenient in this regard are devices equipped with a device for modeling the flame of a burner. 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 change in the temperature of cold water in the system.
But devices with this feature are quite expensive. Those with a limited budget will have to choose from models with stepless or step adjustment.
You will need to set the settings almost before each use of hot water. Typically, the temperature is raised, and then regulate it, mixing cold water with the stream.
The connection of a flowing gas water heater is best done directly, and not through adapters. Before buying, you need to check the diameter of the connecting elements and compare them with the dimensions of gas and water pipes
Instrument dimensions and installation method. The most popular models are usually small, wall-mounted and vertical. If a speaker location has already been selected, you should familiarize yourself with the manufacturer's requirements. Perhaps the device can not be installed close to the cabinet, wall and other objects, you need to provide a certain clearance.
The presence of a display that reflects the state of the column and the temperature of the water flow is very desirable, but not necessary for the normal operation of the device
Additional factors. It is necessary to remember such moments 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 the specifics of fulfilling warranty obligations.
Problems with installation and warranty are typical for some imported devices.
Additional recommendations for choosing a gas column are described in this article.
Efficient use of the appliance
When operating gas units, two serious hazards must be considered, such as the likelihood of poisoning by gas fuel processing products and an explosion. That is why you should never neglect the scrupulous study of the operating instructions and the fulfillment of all its requirements.
Modern speakers with a mechanical control system are usually very simple to operate, if the settings are set correctly, the device will supply a stable stream of enough hot water
To ensure sufficient traction 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 movement of air flows.
The installation and connection of the column, its maintenance and necessary repair procedures must be carried out by a gas industry employee; acting on these issues can seriously harm
In order for the column to work normally, it makes sense to arrange a suitable version of the supply ventilation. Before turning on the column, a traction check is mandatory.
It is best to use tissue paper for this, rather than matches or a lighter. If gas has accumulated inside the case due to a breakdown, it may explode.
The presence of sufficient draft can be judged by the flame on the igniter: if the tongue deviates towards the chimney channel, then there is draft. But it’s safer to use thin paper instead of fire.
It is important to understand that the unauthorized installation of a geyser is fraught not only with penalties, but also with much more serious consequences.
You cannot repair a broken column yourself or make your own design changes. This can lead to a potential gas leak and subsequent explosion.
The heat exchanger becomes clogged with scale over time and has to be cleaned periodically.
Improper use of the geyser can lead to its pollution. To restore the unit to normal operation, clean it.
To make this process as slow as possible, you need to set the heating temperature correctly. The higher it is, the more limescale. The maximum recommended rate is 55 ° C.
If the column does not light up due to low water pressure, it may be time to clean or replace the water pipes. It’s best to take care of this before purchasing and installing the appliance.
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 does not hurt to first drain a certain amount of water and remove the accumulated air.
How reliable and safe are modern speakers:
Tips for choosing the right model:
The range of speakers from different manufacturers is quite wide. You can always choose a productive unit for the right price. Subject to the rules established by the manufacturer, the heater will work for more than ten years without breakdowns or problems.
