Choosing a water heater

Gas and electric water heaters - the advantages and disadvantages. Comfort in an apartment depends on hot water. Unfortunately, local utilities do not always provide this comfort. Gas instantaneous water heaters ("geyser") gas column, perhaps the most famous in our country, a device for individual hot water supply. Nevertheless, it is understood that between the gas pumps, which ustavlivalis in "Stalin" and "Khrushchev," and advanced gas instantaneous water heaters there is a huge difference. Leader in the manufacture of gas instantaneous water heaters (geysers) is a Swedish concern Electrolux. These water heaters are completely safe in operation: safety valve thermocouple override the gas supply if the burner goes off accidentally. Ignition System Heater is fully automated and requires no adjustments, while ensuring complete combustion of natural gas during start-up. Electrolux gas water heater is made from high quality materials (stainless steel, pure electrolytic copper). In these gas water heaters can smoothly adjust the water temperature, and the automation will ensure its permanence, regardless of water pressure drops. The main advantage of the gas cylinder before the electric - it cost (electricity tariffs are higher than for gas). The rest of the gas-flow water heater is virtually identical to the electric consumer properties. Gas water heaters vary in power. If you do not need to use both a shower and, for example, washing dishes in the kitchen is quite suitable heater power 18-19 kW, but if you'd like to use the shower and sink in the kitchen at the same time, it is necessary to power the water heater is 24 kW. Electric water heater: flow or storage? First and foremost, you need to decide what kind of water heater will suit you best - running or savings, and then pick a suitable container and power. Electric water heater (boiler) heats the water to 55-75 degrees, after which maintains its temperature in an automatic mode. Since the heating takes place gradually, boilers do not require much electrical power and in most cases can be plugged into a standard electrical outlet. Even a 150-liter water heaters consume mostly no more than 1,5-2 kW. It is a small power consumption, allowing water heater installed in virtually any room, providing a high demand for these devices. A second advantage of storage water heaters is that hot water may consume more water-points simultaneously, ie at the same time you can turn on a shower and wash dishes in the kitchen. On the other hand, the shortcomings of water heaters include heater dimensions, as well as the need for periodic maintenance: replacing the magnesium anode, cleaning of the heating elements of the scale. It should also be borne in mind that the volume of hot water heater to limited capacity, and for the next heating "portion" will take time. Capacity of the water heater can vary from 10 to 500 liters. To pick up the required volume should be aware that in order for one person to take a shower, you need 25-30 liters of hot water. If someone else wants to just take a shower then, the volume of the water heater must be at least 50 liters. To the third man was able to take a shower or to increase the volume again, or wait until it heats water in a small water heater. So for example for the fact that heat water from cold to hot conditions in the boiler capacity of 30 liters to 45 minutes to 1 hour. So if you want to install a 30 liter water heater and one person takes a shower, the other will have to wait about an hour until the water warms up. There is a perception that taking a shower is enough 10-liter tank. Unfortunately, it is not. Shower should be at least 4 liters of warm water per minute. This 10-liter water heater, mixing with cold water at the outlet of the shower will give approximately 20 liters of warm water. That's enough for a maximum of 5 minutes of showering. Then he would go only cold water. Therefore, the volume of 10-15 liters of water heaters used for washing dishes or to wash hands, wash. Assumed that water heaters take up much space, which is not entirely untrue. There is also a compact water heaters, which can be located even under the sink. Well, if you want to live in comfort the whole family, regardless of the vagaries of public services or do not wish to abandon the benefits of civilization in the country (take a bath, shower, etc.), the need really big boilers with a capacity of 100 liters or more. In order to heat the water in this device from 12 to 70 degrees, take about 3,5-4,5 hours. Water in storage water heaters cools very slowly, like a thermos. In qualitative boilers drop in temperature does not exceed 0,25-0,5 degrees per hour. Therefore, in the cities where night preferential electricity tariff, it makes sense to heat water in advance - at night. There are storage water heaters that run on multiple sources of energy. Such a heater will be useful to the country or a country house, where there is a heating system, a centralized or autonomous (from his boiler). During the heating season, heating the water will come from the coil connected to the heating system, and in the warm season, from the electric heater. In electric instantaneous water heaters heat water directly, passing through the heating element of high power (capacity from 6 to 27 kW), so the heaters of this type immediately removed from the network more, compared with boilers, the amount of electricity. On the other hand, instantaneous water heaters can produce an unlimited amount of hot water and does not require regular maintenance. However, unlike storage water heaters, they give out warm water, not hot and can not provide hot water several points simultaneously. By virtue of greater power consumption, require separate connections for electrical cable from the electrical panel to the heater. If you want to install flow-through water heater is necessary that the cooker was always electric and not gas. Only in this case, the power wiring, which is fed into the apartment and located in the entrance enough to install this type of water heater. In that case if you want to install flow water heater in a country house or cottage, be sure to consult an electrician if you have enough network capacity to install this type of water heater. Depending on the purpose for which you want to use an electric instantaneous water heaters, you will need different amounts of warm water. So, to wash the dishes require about 4.6 kW is 2-3 liters per minute shower requires a minimum of 8 kW is 4 l / min. If you want to take the bathroom, then you need water heater having a capacity of not less than 13 kW power supply for it already need food for three phase voltage of 380 V. The majority of apartments with electric cooker power 380 is not supplied, so if you want to buy a water heater with a voltage 380, then the first must find out whether supplied to you such stress, and if not, whether you take it.
