gas and electric water heater



Gas water heaters (or geysers) are connected to the main water supply and pipeline.Due to the combustion gas heat exchanger is heated and the water flowing through the tubes, receives heat.Electric water heaters operate from the network (single - or three-phase 220 V - 380 V).

Once the decision to purchase a water heater is accepted, the question of what type to choose - electric or gas, usually solved quickly enough.If the house held the pipeline and allow its design features, therefore, better to buy the gas, since this type of cheaper electrical devices.If the gas is excluded because of the lack of gas, it should give preference to the electric water heater.

Cumulative and instanta
neous water heater



If you have decided on a source of energy for water heating devices, you can go to a choice between instantaneous or storage water heaters.Its advantages and disadvantages are those and others, there should be chosen based on the specific characteristics of your apartment or house in the country, as well as your individual needs.

Storage water heater is also called boiler.There the water is heated to a certain temperature (typically 60-70 °), then the device automatically maintains it.If the heated water is used partially or completely, from the water topped new.She then reheated.Since water heating in the boilers going quite smoothly, their power consumption is relatively low. boilers consist of a vessel that may have a volume of from 30 to 500 liters.

Install a water heater can be in any home or apartment, it is not too resource demanding wiring.In addition, one of its main advantages is that it can provide hot water once the whole apartment.Carry out the water from the boiler and can be in the kitchen and in the bathroom and other rooms, where it may be needed.

main drawback of storage water heaters - their size.If you have a bathroom in the apartment is relatively small, with a defined volume of the boiler should be based on its size.For example, in a standard bathroom Khrushchev unit volume of more than 100 liters, is not fit.Even if it can be set to turn around with a bulky water heater will be problematic.

Therefore, choosing a storage type water heater, first of all need to determine its volume.It depends on various factors:
- the availability of space in your house or apartment;
- the number of your family members as well as their love for washing dishes or water procedures.

one person on showering you need 30-40 liters of hot water.Therefore, even for a small family, which consists of 3 persons, the most convenient would be big enough boiler - a volume of 100 liters.These giants are heated for a long time - at least 3 hours.If the family you have not got, we can give preference to small boiler of 40-50 liters.In the heat it takes only 30 minutes, the hot water will be enough to take a shower.Furthermore, the energy it consumes much less.

It should also be borne in mind that about 1 every 2 years would be necessary to invite the master, so he cleared an additional heating element (TEN) from the scale, otherwise the device memory type will last a long time.

flow-type water heaters for their work require a lot more electricity.Besides, they are critical to the state of the wiring in the building.Before you opt for a flow-through embodiment, it is advisable to consult a specialist, whether stand wiring in your home that "the consumer." water temperature in the flow device is enhanced by passing through a heat exchanger.It depends on the power and pressure of the water heater.

Quite often old wiring not withstand the strong current that takes a water heater.Its isolation melts and a short circuit.To resolve this problem may help to separate cabling directly from the board, but this is possible only after prior consultation with an electrician and in its execution.Another disadvantage instantaneous water heater is the fact that it can provide water only one room - or the kitchen or the bathroom, you have to choose.

course, flow models also has its advantages;
- unlimited amount of water;
- instant hot water;
- due to the absence of the tank, they take up little space;
- usually, these devices do not require regular cleaning and periodic maintenance.
