Every summer, many citizens trying to solve the problem of lack of hot water, which is almost a month disconnected for prevention.Rural residents and the owners of country cottages familiar with this problem is even better: after the heating season comes to an end, it is necessary for the whole summer to look for a way to heat water for household and domestic use.Not surprisingly, many are beginning to think about how to choose a water heater, and we consider one of the most popular types - accumulative.

Features storage water heaters Water heaters

are flowing and cumulative.Work flow heater based on the fact that the water passing through the hot heating element is heated to the desired temperature (read about it here).Such devices are compact and easy to use, but if you need a lot of hot water, to get it, they are required more power (up to 8 kW), which is able to withstand not any wiring.

device such unit is quite simple: in the tank, which is filled with cold water, the heating element is installed which heats the water to the desired temperature (from 35 ° to 85 °), then turned off automatically.When the cooling water in the storage ring by half a degree heating element is switched on again and bring it to a predetermined temperature.(Of a solid foam often) water to cool down slowly between the storage tank and the outer wall is laid a layer of insulation.

average power of about 2 kW of devices (in the range of 0.9 - 6 kW).So the main thing - to calculate the right amount of power and your tank.For example, if you need to heat 50 liters as soon as possible, suitable boiler 2 kW, if the heating rate is not important, you can purchase a unit of the same volume capacity of 1.2 kW.

Types

Savings (capacitive) water heaters are gas and electric.

electrical capacitance heaters have a simple device they consist of an inner tank, a heating element (PETN), the magnesium anode (to prevent occurrence of corrosion on the inner tank), the thermal insulation of the outer shell, a thermostat (to set the desired temperature), safety valve (overpressure pits).

distinguish these devices not only in volume (5 liters to 550 liters) capacity PETN, and material thermal insulation (polyurethane, polyurethane foam, mineral wool), tank cover type (stainless steel, enamel, glass porcelain), location (vertical or horizontalover or under the sink).

Gas DHW cylinders in Russia are less popular than power, though often much more economical and profitable to them, because gas is cheaper than electricity several times.

Gas heaters storage type can be open or closed combustion chamber (with natural or forced draft).Last expensive, but their installation does not require a traditional chimney and an additional air intake for combustion.

storage water heaters: brands and prices

price of storage water heaters depends on the manufacturer, the quality of steel or enamel, which is made from a tank, some design features.For example, the Italian unit per 100 liters of Isea costs only $ 175, and the German of the same volume of Stiebel Eltron - more than $ 500.While the device of the same, but the German boilers have a slightly larger amount, as they took the great insulation.As a result of this construction, water per day only cools to 5 °, which leads to considerable energy savings.

heaters with enamelled tank are cheaper such as a stainless steel tank (from 30% to 100%), but also serve as such tanks are much longer.

Tips for Choosing a water heater

to choose the right amount of water heater.you need to consider how many people in the family, how many points will be served by the unit and individual needs in hot water.For example, one person is required for bathing an average of 150 liters of water for a shower - 70 L, washbasin - 10 liters, to kitchen sinks - 25 liters.

installing electric water heaters, do not forget to take care of security: be sure to make grounding for devices with capacity of more than 2 kW set a good wiring with automatic cut-off, do not place the boiler next to a radiator and suspension models are mounted on load-bearing walls with powerful hooks.

Storage water heater - this is really simple, convenient and cost-effective solution for producing hot water.The main thing - the right of his choice.
