Without hot water, comfort in the house is unthinkable. Even the presence of a separate bathhouse in private estates is not a sufficient basis for refusing an internal water supply. If only because the bathhouse does not replace a hot shower or bath in the hot season, when you have to wash several times a day.
And the dishes require hot water. It is not surprising that for many the real painful place is the question of how to choose a gas column. This can be explained quite simply: if before a
gas-fired flow-type
water heater was actually a tank with an atmospheric burner and a crane system, now many columns have acquired an intelligent flame control system (modulation), various ignition solutions, etc. Since there are problems with where to buy a gas column, now does not arise, because they are in every household appliance store, then we will consider some basic selection criteria. Since it is impossible to cover all the nuances in one article, we will dwell on only some key points.
Some recommendations
Before sorting out the question of how to choose a gas column, we will point out a number of general features. Before you go to the store for a purchase, you should decide on the necessary shape, dimensions and installation location of a new household appliance. Otherwise, you may encounter a situation where the purchased column will not be possible to place in the planned place or you will need a change in the interior and related structures, which, although feasible, is unlikely to please anyone. The classic coloring of this group of devices is white, but recently the market has offered other options. Also, many are interested in the question of how to install a gas column. The answer to it is simple: this is a job for representatives of the gas economy of the village. If installation and connection to the water supply system can be done on their own, then connection to the gas system is allowed only to gas workers. They also give permission to organize a system for the removal of combustion products.
Power
So how to choose a gas water heater? One of the key characteristics that consultants pay attention to is the power in kilowatts. It has nothing to do with the electric parameter of the same name, just indicating how quickly a certain amount of water will be heated per unit time. In other words, if you plan to use the column at one time for several water outlets, then you need to consider options with a power of 20 kW or more, but for a bath alone or even more a shower, 17 kW is enough. It is difficult to name exact values, since it all depends on a person’s preferences: one bucket of warm water is enough for one, and the boiling water will not seem enough to the other.
Ignition
The most common devices with one of three ignition options. The simplest is a manual piezo. In such solutions, a system with a button is installed inside, when pressed, a spark arises and ignites the igniter flame. Then, when the hot water tap is opened, the main burner ignites. Although the ignitor can be left burning, its constant use leads to an excessive consumption of gas.
Two other solutions allow you to automate the process. In the first, a spark from batteries is used for ignition (it is necessary to periodically change), and in the second, from a small hydrogenerator, the blades of which are rotated by the water flowing through the pipes (when the tap is opened).
Adjustment
Few people know that the temperature of the water should be adjusted so that it does not require dilution of the cold. Three solutions are used for control: stepwise and smooth adjustment, as well as automatic modulation of the burner fire. In the first two cases, the desired heating level is pre-set (depending on the pressure), but in the second, the column itself controls the flame intensity, maintaining the desired temperature.
In how to choose a gas column, there is nothing complicated. Everything determines the budget and the desired characteristics.
