Types of gas and flow accumulation boilers for heating water
As a model, running on electricity, gas water heaters are divided into the following types:
- savings - the water is heated to the required temperature in a special tank, which also bears the storage function. Subsequently, the owner may at any time use The stored volume of hot liquid.
Due to the impressive size such "titans" separate spacious accommodations needed
- flow - water flow passes through the apparatus, heating and immediately getting to the host through the mixer.
Oh, how many women are grateful to the inventors of the gas column for the opportunity to quickly put himself in order
However, such a division is too broad and superficial. We offer you to consider a more detailed classification of the heroes of our review.
A gas water heater with open combustion chamber - imaginary benefit
Budget at a cost, but expensive for additional work look. For full operation boiler required air flow, which is taken directly from the room. All installation difficulty lies in the fact that you will have to make a separate chimney for flue exhaust and ventilation - it is a waste of money, time and effort.
Buy a gas water heater is certainly possible, but only if there are ready-made communications or if there is a very limited budget.
Aside from the hassle of installation of communications, you will have to periodically check the appliance on fire safety and monitor it
A gas water heater with closed combustion chamber - a safe and economical way
The next stage of development of gas appliances for heating water are accumulative pattern with closed combustion chamber. Unlike the precursors have no access to the air inside the room, and a discharge line for the exhaust gases is carried out at the expense of a special pump. These characteristics have a positive impact both on the reliability and on the health of residents. In fact, this version can safely assume that the gas water heater without a chimney - you need to make a small hole in the wall and for mounting to combine access to the water heater in the wall. The rest - the fan operation.
In addition to these advantages, the system is more and simpler in its design. No wonder they say "All ingenious - is simple"
Despite the fact that in order to complete the work cylinder with a closed combustion chamber requires coaxial chimney, their application will be more favorable in all respects. But such a solution would be almost ideal for owners of private houses.
Accumulative gas water heater with automatic pezorozzhigom e - keep strong tens precious minutes
To start you need to use matches or lighters dedicated budget and legacy devices. More modern and innovative products have simplified the lives of their owners by the presence of the piezoelectric element or automatic electronic start-up and shutdown.
The motto of the first modification is a famous expression "press the button - get the result!". To enable this heater only need to make one-touch, creates a spark - and that's already a bright flame heats the much-needed water for household needs.
For the functioning of pezopodzhigom not even need a mains - all works on batteries
But even this advantage seems to be insufficient by some masters. For such people, there are products equipped with electronic automation. In this case, the operation easier and more convenient - for you just open the faucet for hot water in a blender. The system itself will activate heating, and when closing the valve extinguish flame.
Automation is a sophisticated electronic system susceptible to damage wires - beware of random failures!
NOTE!(Click to see)
Despite the convenience and practicality of the automatic on / off gas from these structures also have a drawback - they are less stable than a manually operated device. In this regard, water heaters with electronic automation need regular maintenance and functional testing apparatus elements.
Flowing gas column - the "younger sister" storage heater
Unfortunately, not always possible to buy a gas water heater storage type. In this situation, the best choice would be the acquisition of the gas column. It is also present tank, but more compact. The heated liquid in such a modification, passing through the tank is supplied directly to the owner. Keep the water flowing in the column will fail, but the service life and efficiency are at a very high level.
Another important advantage of the gas column is the ability to harmoniously fit it, not only in the bathroom interior but also the kitchen
Important parameters of capacitive gas water heater - what to look for
It passed the first important point of our small study. But, wondering "How to choose a gas water heater?", One can not ignore this section as the technical and operational characteristics. Let's take a closer look at the most important parameters:
Power and Performance
Almost any household appliances the most important indicator, revealing the full potential is the nominal power. As is the case with an electric water heater, the hero of our review of the value measured in kilowatts.
In practice, the power depends on another important characteristic - productivity. For visual confirmation of these words suggest to familiarize with the table according to two characteristics.
| The value of power in kW | The maximum amount of water, heated to 30 ° C, l. / Min. | The maximum amount of water, heated to 50 ° C, l. / Min. |
| 20 | 13 | 6 |
| 26 | 16 | 8 |
| 30 | 18 | 9 |
NOTE!(Click to see)
We also have a performance is an important parameter, and his name - storage volume. Read the instructions, you can see a direct relationship between how many liters can accommodate the heater and how long the water will be heated up to a certain temperature.
Wrong selection of boiler volume will lead to a queue in the bathroom and conflicts in the family. Avoid like, use the table!
Materials used subcoating + type tank
Today, the two most common material for manufacturing the internal structure of the tank - an ordinary steel coated with a layer of enamel or "stainless". The first option is more cheap and durable, but susceptible to rapid degradation due to corrosion. The second variation has good durability, but more degraded by the system, as well as the high cost of different pressure drops.
For the most common gas columns one tank casing material is copper
For an inner coating or containers used previously referred enamel (also occur model with glass porcelain), or sputtering from various corrosion resistant metals (titanium, molybdenum). Each version has its useful life, and depend primarily on the intensity of use and the heating temperature.
Unfortunately, the enamelled pots are easily damaged due to the periodic load water - antikorroziruyuschie cover much more effective
Type combustion chamber
As we have been told, there are units with open and closed combustion chamber, and each has its own strengths and weaknesses. Wrong choice of instrument would entail extra costs and can completely meet your goals and expectations. In the absence of certainty is better to give preference to the classical flow of the gas column - the risk would be minimal.
Visually distinguish types of combustion chambers is not so difficult, the principle laid down in the title
Method startup ignition
If you have only a modest amount of money, or you want full control over the work process water heater - it is better to take a model, in which the gas is ignited with matches, lighters or piezo. If we want to save time and energy costs, you should look for models with automatic start / stop.
For manual "ignition" is characterized by a direct ignition circuit, for automated - igniter
The presence of a sacrificial anode
To prolong the life of the device and to improve its corrosion resistance, many manufacturers equip their "child" zinc or magnesium anode. In use, this element is gradually "evaporate", dissolving and preventing the violation of the integrity of the tank. The presence of this "bloat" is better to check with the seller or the manufacturer's website.
In the presence of hard water and very active operation of the boiler plate quickly fail, and his replacement will require skilled professionals
gas water heater installation Features
As with any particular technology, in gas boiler has its own nuances associated with the preparation and installation. To better focus on this issue, we invite you to look a little video from which you can gather a lot of useful information:
