Types of gas storage and instantaneous boilers for water heating

Like models that run on electricity, gas water heaters are divided into the following types:

  1. Cumulative - the water is heated to the required temperature in a special tank, which also serves as a storage facility. Subsequently, the owner can use the stored volume of hot liquid at any time.
     Due to their impressive dimensions, such " titans" need separate spacious rooms.

  2. Flowing - the flow of water passes through the device, heating up and immediately getting to the owner through the mixer.
Oh, how many women are grateful to the inventors of the gas water heater for the opportunity to quickly put themselves in order.

However, such a division is too extensive and superficial. We suggest you consider a more detailed classification of the heroes of our review.

Gas storage water heater with an open combustion chamber - an imaginary benefit

Budgetary in terms of cost, but costly in terms of additional work. For full functioning boiler an air supply is required, which is taken directly from the room. The whole complexity of the installation lies in the fact that you have to make a separate chimney for the removal of combustion products, as well as ventilation - this is an extra waste of money, time and effort.

It is certainly possible to buy a gas storage water heater, but only if you have ready-made communications or if you have a very limited budget.

In addition to the hassle of installing communications, you will have to periodically check the device for fire safety and monitor it

Gas storage water heater with a closed combustion chamber - a safe and economical option

The next stage in the development of gas technology for heating water is storage models with a closed combustion chamber. Unlike their predecessors, they have no access to air inside the room, and exhaust gases are removed by a special pump. These characteristics have a positive effect on both the reliability and health of the residents. In fact, such a version can be safely considered a gas water heater without a chimney - you need to make a small hole in the wall and, during installation, combine the outlet in the water heater in the wall. The rest is the work of the fan.

In addition to the described advantages, such a system is also simpler in design. No wonder they say "Everything ingenious is simple"

Despite the fact that a coaxial flue gas outlet is necessary for full-fledged operation of water heaters with a closed combustion chamber, their use will be more profitable in all respects. And for owners of private houses, such a solution will be almost ideal.

Accumulative gas water heater with piezo ignition or electronic automation - will save tens of precious minutes

To start budget and obsolete devices, you must use matches or specialized lighters. More modern and progressive products have simplified the lives of their owners by the presence of a piezoelectric element or automatic electronic start-up and shutdown.

The motto of the first modification is the famous expression “Press the button - you will get the result!”. To turn on such a heater, you just need to make one press, a spark is created - and now a bright flame heats up the water so necessary for domestic needs.

For the functioning of the piezo igniter, you do not even need an electrical network - everything works on batteries

But even this advantage seems insufficient to some owners. Especially for such people, there are products equipped with electronic automation. In this case, operation is even simpler and more convenient - to use you just open the hot water tap in the mixer. The system itself activates heating, and when the valve is closed, it extinguishes the flame.

Automation is a complex electronic system with wires sensitive to damage - beware of accidental breakdowns!

NOTE!

Despite the convenience and practicality of automatic gas on / off, such designs also have a drawback - they are less stable than manually controlled devices. In this regard, water heaters with electronic automation require regular maintenance and checking the functionality of the device's elements.

A flow-through gas water heater is the "little sister" of a storage boiler

Unfortunately, it is not always possible to buy a storage-type gas water heater. In such a situation, the best choice would be to purchase a gas water heater. It also has a tank, but more compact. The heated liquid in this modification, passing through the container, goes directly to the owner. It will not work to store water in a flow column, but the service life and efficiency are at a very high level.

Another important advantage of the gas water heater is the ability to harmoniously fit it not only into the bathroom interior, but also the kitchen

Important parameters of a storage gas water heater - what to look for

The first important point of our little research has been passed. But, asking the question "How to choose a gas water heater?", One cannot ignore such a section as technical and operational characteristics. Let's take a closer look at the most important parameters:

Power and performance

For almost any household appliance, the most important indicator that unlocks its full potential is the nominal power. As in the case of an electric water heater, the hero of our review has the value measured in kilowatts.

In practice, another important characteristic depends on power - performance. For a more visual confirmation of these words, we suggest that you familiarize yourself with the table of dependence of the two characteristics.

Power value, kWMaximum volume of water heated up to 30 ºС, l / min.Maximum volume of water heated up to 50 ºС, l / min.

26168
30189

NOTE!

Performance also has its own important parameter, and its name is the size of the drive. After studying the instructions, you can notice a direct relationship between how many liters the heater can hold and how long the water will be heated to a certain temperature.

Materials used + type of tank lining

Today, there are two most common materials for the manufacture of the internal tank of the device - ordinary steel, covered with a layer of enamel, or "stainless steel". The first option is cheaper and more durable, but is subject to rapid destruction due to corrosion. The second variation has good durability, but it is more destroyed by pressure drops in the system, and also has a high cost.

 For gas water heaters, the most common variant of the tank body material is copper.

For the inner coating of the container, either the previously mentioned enamel is used (models with glass porcelain are also found), or spraying from various corrosion-resistant metals (titanium, molybdenum). Each version has its own useful life, and depends primarily on the intensity of operation and heating temperature.

Unfortunately, enameled tanks quickly fail due to periodic water loads - anti-corrosion coatings are much more effective

Combustion chamber type

As we said earlier, there are units with an open and a closed combustion chamber, and each has its own strengths and weaknesses. The wrong choice of the device will entail unnecessary costs, and may also completely not meet your goals and expectations. In the absence of complete confidence, it is better to give preference to the classic flow-through gas column - the risk will be minimal.

It is not so difficult to visually distinguish the types of combustion chambers, the principle is laid down in the name itself

Ignition start method

If you have only a modest amount of money or you want to completely control the work process water heater - it is better to take a model in which the gas is ignited with matches, a lighter or piezoelectric element. If you want to save time and energy costs, then you should take a closer look at models with automatic start / stop.

Presence of a protective anode

To extend the life of the device and improve its resistance to corrosion, many manufacturers equip their "offspring" with a zinc or magnesium anode. During use, this element gradually "evaporates", dissolving and preventing damage to the integrity of the tank. It is better to check with the seller or on the manufacturer's website about the presence of such "bells and whistles".

In the presence of hard water and very active operation of the boiler, the anode will quickly fail, and its replacement will require the services of qualified specialists

Features of installing a gas water heater

As with any specific technique, gas boilers have their own nuances associated with the preparation and installation. To better navigate this issue, we suggest you watch a short video from which you can glean a lot of useful and necessary information:
