Water heaters how to choose a good model - species description

bothered to adapt to the schedule of the hot water or warm water at all in the pots and bowls?Then it's time to buy a water heater!Today, manufacturers offer a huge range of boilers distinguished by the method of heating the water, the source of energy and a number of technical and operational characteristics.The following information will help you understand the intricacies of selection vodogreyki and come to the most successful solution.

boilers Classification according to the method of heating water

In accordance with the method of heating water all the existing boilers can be classified on the storage and flow.

Cumulative vodogreyki

design of the storage water heater is a sealed tank.First container is filled with liquid, and then only it begins heating.The main characteristic of the boiler is accumulating its scope.

electricity consumption average.All current models of water heaters can operate in standard and high speed.Standard mode is suitable for regular use, fast, specially designed for those situations when suddenly there was a need for a small amount of warm water.

Among the important advantages of the storage tank should include ease of installation and connection to the water supply, ease of use, the possibility of including in the common electricity grid.

The main drawback of this kind of units is their size.Thus, the larger the volume of the tank, the heavier it.We'll have to not only figure out where to put the barrel, but also to make sure that the wall can support its weight.

storage water heaters are best suited for installation in apartments and houses that are used for permanent residence.

Flowing water heaters

Such units are deprived of keyshortcomings their accumulative "brothers".Instantaneous water heater - is a compact unit that provides almost instant hot water.The liquid is heated in the process of passing through the boiler, which eliminates the need for its accumulation and saving the space required to install the device.

main disadvantages instantaneous water heater - this is a high energy consumption and heavy loads on the network.At the same time this kind of units demanding wiring - simply fix the device on the wall and turn it into a power outlet in most cases impossible.

Flow models are best suited for kitchens, villas and houses not used for permanent residence.

The inlet heater

For areas without running water (garden, garden, etc.) is perfect for a bulk water heater.The structure is made as an average volume capacity of 15-20 liters.The product has a light weight, which allows to hang it almost anywhere.

principle of using this heater the following:

• in a container filled with water;
• heater is included in the grid;
• after a while (depending on the power installed heating element), you can open the tap and use heated water at its discretion.

If necessary vodogreyke connected hose showerhead.

Classification of boilers according to the source producing

energy When choosing a water heater should pay attention not only to the liquid heating method, but also the source of energy.There vodogreyki able to get energy from:

• firewood;
  

  wood heater

• electricity;
• gas;
• sunlight.

Wood boilers

The principle of wood vodogreyki largely similar to the mechanism of action of the stove - to generate heat burned wood.Such heaters are mainly used in country houses, in public and private swimming pools, trains, etc.

plant consists of three main elements: a. The furnace tank and a mixer.In the furnace the solid fuel combustion occurs.The heated air flows into the pipe, which was started through the tank and its heat to the fluid.

Such a water heater has many drawbacks.Chief among them is the need for regular laying the fuel manually, which is not particularly convenient.Also disadvantage of this design is the relatively long time of heating water.

Electric boilers

most popular modification of the water heater.Heating water by means of powerful heaters installed inside the structure.The advantages of electric heating are the following factors:

• ease of installation and connection;
• economical operation;
• high efficiency;
• ability to use virtually anywhere there is access to electricity.

Gas vodogreyki

Such installations are widely used in a private household.They can connect to both a stationary pipeline and to cylinders of liquefied fuel.

gas installation is very easy to use, but in terms of economics, they lose much their electric counterparts.

Solar Heaters

rapidly gaining popularity kind of equipment for the heating of water.The basis of design - special collectors.They accumulate the solar energy and use it to heat the liquid in the storage tank.

main advantage of solar water heaters - economical operation.Such devices do not require the application of external sources of supply.

Disadvantages:

• relatively high price;
• long heating time;
• depending on the light level.
  

  Solar water heaters

For continuous use of solar water heaters do not fit.

Main technical and operational characteristics of boilers

selecting the optimal method of heating and the most convenient source of heat, you can proceed to the consideration of the key characteristics of the water heater.When choosing vodogreyki pay attention to the following points:

• power unit;
• material coating the inner tank and its volume, if the selected model is cumulative;
• reliability and safety of operation.

Power

From this index directly depends on the duration of operation of the device and the intensity of water heating.Among all of the models of water heaters are considered to be the best electric and gas, with the gas equipment, ceteris paribus, on average 2 times superior to the performance of units operating on electricity.

Gas unit operates at constant power and warm water as soon as possible.Device capacity of 3.2 kW for 4.3 hours can heat 150 liters of water by an average of 50 degrees.

The electrical models for fluid heating heating elements meet.Typically, boilers are equipped with 2-3 heating elements with a total capacity of 2-3 kW.If you need a large volume of hot water is not available, part of the heaters can be switched off to save energy and

Thus, for a family of 3-4 people is enough water heater capacity of 2-3 kW.For the rest, be guided by your requests.

tank coating

From the inner coating material accumulating boiler service life of the unit depends on many things.Total use 3 types of coatings: deposition of titanium-based, glass porcelain, stainless plating.

best option - coating on a titanium or stainless basis.Such spraying calm will last 7-10 years or more.Stainless steel and titanium endure temperature swings and normally are resistant to all sorts of impurities present in the composition of the water.

glass porcelain - a budget option.However, for long life vodogreyki with internal coating can not count - manufacturers give them a maximum of 1-3-year warranty.Glass porcelain does not tolerate aggressive exposure and high temperatures.In such circumstances the material quickly covered with microcracks and begins to rapidly deteriorate.

To extend the life of the internal coating manufacturers bundle their products with special magnesium anode.In vodogreyke with stainless steel or titanium coated anodes, such change is usually not necessary.If the inner walls of the tank are covered with enamel, replacing the magnesium anodes have to spend at least annually.

reservoir volume

Capacity is a key parameter storage vodogreek.In determining the optimal amount of thought of everything so that water is not just enough, and it was with a small margin.

Tank Capacity Pick up according to their needs.So, for washing dishes and enough tank to 10-20 liters.If the boiler will heat water for showering, bathing and other household needs, pay attention to the model of not less than 80-100 liters.

Important!Tank capacity is directly linked to a number of other parameters.The capacious boiler, the more time will be spent on water heating.And place a large barrel takes a lot.

points of consumption	Shower / kitchen sink	Shower / kitchen sink	Shower / kitchen sink / bath	Shower / kitchen sink / bath
Number of users	1	2	3 (2 adults + 1 child)	5 (2 adults + 3 children)
consumption volume of hot water	10-30 liters	50-820 liters	80-100 liters	150-200 liters
Recommended cylinder capacity of 50 liters		100 liters to 150 liters		300 liters

Safety and reliability

When choosing a water heater should pay attention to a number of additional parameters.First of all, get in the technical description of the model the maximum heating temperature.The best option - 60-65 degrees.

Well, if the boiler is equipped with a temperature sensor and thermostat.

Equally important is the quality of the interior tank insulation.The more effective it will be, the lower the result, you have to spend money to pay the bills.

Selecting heater - not such a difficult task.Now, you own all the necessary information for this purpose.Determine the most suitable option for you to heating, the most convenient source of energy, optimum power and other relevant characteristics, and go for a new water heater.
