How to choose a gas column: the recommendations of professionals

Do you think that the gas boiler is a relic of the past and today nobody installs it? You are mistaken, it is still a necessary household appliance, without which it is sometimes impossible to do. Do you have lukewarm water in the tap or even hot water in general comes according to someone’s invented schedule? The boiler, of course, is a good way out, but not always the electrical networks of the house allow it to be installed. And in this case, the gas column is an indispensable option. About,how to choose a gas column, today we will tell.

Modern gas water heater

How to choose a gas column: market review

To begin with, what geysers are offered today. They can be chimney and turbocharged (without chimney).

Chimney geysersIt should be installed in the old houses like "Khrushchev" and "Stalinok", where the columns already stood and there is a chimney channel. It is into it that the combustion products are discharged through a coaxial pipe. For high rises - this is the best option.

Chimney

Turbocharged gas water heatersit is preferable to put in private homes, as the products of combustion are brought out directly through the wall. In a column of this type, fresh air is taken along one pipe, and gases go outside through another.

The principle of operation of the gas column

Geysers differ as well as inclusion type. They come with manual ignition, with electronic ignition, as well as piezo ignition.

Columns of the first type remember, probably, everything. I had to bring a match and wait for the fire to flash in the column. The size of such a unit was practically with a refrigerator, it is not necessary to speak about convenience. And although they are no longer being released, in many apartments you can still find these "prehistoric mammoths", to which it is even scary to approach.

Old gas boiler

A more modern version is a piezo-ignition column, when it is enough to press a button to turn it on. When it is pressed, the piezoelectric element acts, which gives a spark for ignition of the burner.

The most modern and easy to use option is a column with electronic (automatic) ignition. It does not need to press anything, the column starts to work when you open the tap with hot water. For ignition the battery which gives a spark is used.How to choose a gas column - read on.

How to choose a gas column: how much power is needed

Productivity on hot water - the main parameter of a gas column to which it is necessary to pay attention at the choice. It is measured in liters per minute and is related to such a value as “delta T”, which is denoted as ΔТ. This is the value by which the temperature of the tap water increases when it is heated in the column heat exchanger.

That is, if the column capacity is 10 l / min at ΔТ = 25◦, then the water temperature after heating will be 40 будетС, if at the entrance it was + 15◦С (15◦ + 25◦).

Pezorozhzhig column

If you count on the family that washing the dishes requires a flow rate of 3-4 l / min, and in order to take a shower - 5-6 l / min at a temperature of about 40 ° C, then a gas column with a capacity of hot water 10 l / min.

This is the average for a family of three or a couple with an animal. Based on this, it is possible to calculate the power for families with a larger or smaller composition. For one person, a performance of 7 l / min will be quite enough. For 4-5 people choose a column with a capacity of 12 l / min.

How to choose a gas column: check all the items

A beautiful body is not the most important thing to pay attention to.But the individual elements should be considered more closely.

Heat exchanger. Since this is one of the main component parts, check it carefully. It must be copper, weigh at least 2 kilograms. The most important thing is to check the quality of the soldering in the place of its connection with the “skirt”, otherwise you will be tortured to deal with leaks.

Water blockshould be brass. Pay attention to the diameter of the membrane. For a diameter of 54 mm, the indicated capacity should be 7-8 liters, and for a capacity of 9 to 12 liters, the membrane should be 73 mm in diameter. We recommend to check the validity.

Heat exchangers

Safety sensors. In any modern column there should be at least three of them - a sensor for thrust, flame ionization and overheating. In case of violation of at least one parameter, the column will be securely locked, which will protect your apartment.

DisplayIt should contain information about the main elements - the operation of the thrust sensor, water temperature, battery charge.

Before you choose a gas column, also pay attention to the type of burner. For a constant power burner, manual adjustment is necessary, which is not very convenient, since the water pressure in the system is constantly changing.It will be more practical to choose a burner with modulating power: it will adjust to the pressure of the water flow, while the water temperature will be stable.

The best manufacturers of gas dispensers

Today, geysers of several manufacturers based on various parameters are especially in demand on the market:

Ariston - good quality for reasonable money. They have high efficiency and have a function to maintain the set temperature.

Termaxi - column Chinese manufacturer of good quality. Their main advantage is the presence of a modulation burner.

Column in the interior

Vaillant - German quality does not need comments. Differ in long service life at the expense of the good copper heat exchanger.

Beretta is another Italian brand that enjoys constant success with consumers due to its beautiful design, wide range of models and good quality components.
