Before answering the question of how to choose a water heater, let's see what tools are available on the market.According to the principle of work they are flowing and cumulative.Flow - is such that there is no storage tank.The water is heated when opening the tap with running water.Accumulating - those having tank, and heats only the water that is poured there.For more information about how to choose a water heater on the basis of his work, consider the following.
By type power supply there are devices running on electricity, gas, liquid (diesel oil, fuel oil) and solid (coal, peat, wood) fuel.The latter include boilers that are installed in some of the boiler, in country houses or in the private sector.But because of some technical characteristics, fuel prices and standards setting, they are rarely used.Here's how to choose a water heater between the gas and electric.
Gas has several important advantages.First of all, they have a high capacity, the range of which varies from 4-6 and up to 30 kW, while the electrical performance as little as 1.5 to 12 (in rare cases and only flow) kW.Of course, it will heat the water several times faster.
How to choose a water heater power?We consider useful power, that is, one that provides heating of the liquid.The higher it is, the greater the volume per minute will be heated.But as you need hot water, each defines for himself.It depends primarily on the number of people in the house, as well as the needs of the family.
second significant advantage of gas water heaters - lower gas prices and higher electricity.There are such devices more expensive, but after a short period of time these costs are fully recouped, and then the owner of the unit is the winner.The brands of gas water heaters, there are many.Here are some of them: VAILLANT, ARISTON, DEMIR DOKUM, BERETTA, ELECTROLUX, JUNKERS, MORA, SAUNIER DUVAL.Producing countries - Italy, Germany, Turkey, Czech Republic, Sweden, France.
Unfortunately, gas water heaters have one unpleasant drawback - the difficulty in installation.Here it is necessary to comply with many rules imposed GOST and gas services, build the chimney, to provide the required cubic capacity of the room in which the appliance is installed, and if it is an open burner, ensure ventilation of the room, and so on.If you can do it all - great.If not, stop the choice on electric water heaters, which are installed much easier.
How to choose a water heater Electric storage?There is an important parameter is the volume of the tank and its inner cover.In our market offers devices with a capacity of up to 200 liters.It is clear that for a small family units are not needed.When heated, the excess water will spend the extra electricity you have to pay for.On average, one person, taking into account the fact that he will bathe, wash dishes, do laundry and so on, need 50 to 80 liters of hot water.3 family members will approach the water heater tank with a volume of 100-150 liters.
By releasing the inner cover instruments with a titanium-coated, coated glass porcelain and stainless steel.The most resistant to corrosion - tanks with a titanium coating.They are also the most expensive.Tanks coated stainless steel is also quite persistent.Their term of office is set to 10 years.In addition, they give a magnesium anode helps fight corrosion.As the destruction of his need to change to a new, but with stainless steel tanks it is rarely done.
tanks with a porcelain coating the cheapest, but the magnesium anode in these changes about once every year or two.The second disadvantage - porcelain coating "does not like" the high temperature of the heated water, and can be covered with cracks.
The market has a brand of electrical appliances: ARISTON, IDROPI, ISEA, BAXI, EUROBOILER, THERMEX, AUSTRIA EMAIL, DEMIR DOKUM, DRAZICE and MORA, ELECTROLUX, AUSTRIA EMAIL, SIEMENS and many others.Producing countries - Turkey, Czech Republic, Slovakia, England, Italy, Sweden, Germany.
How to choose a water-heater?Here we must note that this unit gives unlimited amount of hot water quickly, but can not provide multiple points of consumption simultaneously.Power flow is much higher storage heaters.Given the time, because the power is activated only when the heater, the flow obtained economical, but not in each apartment is possible to set the desired power unit.Often this requires eyeliner stronger electrical wires.Consumers who have the ability to install a flow water heater, get a lot of advantages, chief of which is the lack of replacement of the magnesium anode, because these units do not.The second advantage - compactness.Third - unlimited instant hot water at the right time.Fourth - the price.
main criterion for selecting instantaneous water heater, in addition to power, it is the kind of heating element.If this heating elements, it is placed in a sealed vessel and the copper is not in contact with water.Such devices are very reliable in operation and not on the air pockets in the water.But they give outlet water temperature less than 45 degrees.If the heating element is formed as an open helix, it will be in contact with water, but the temperature at the outlet is up to 60 degrees.Most such devices are suitable for hard water.
Marks instantaneous water heaters a lot.Basically, they are produced by the same company as the accumulation type.In addition to these, we note the Israeli and Polish brand ATMOR KOSPEL.
