have heaters that use natural gas for work, a lot of advantages.This small size, and speed of the water heating and durability, and economic benefits. Modern speakers offer high performance and safe operation, but they have a number of technical characteristics, so choose the appropriate option is sometimes difficult.

Types

All heaters are cumulative or wetted.The first option is less common, is more expensive and is used only in case of severe water shortages.

Running geyser Flow geyser

Most heaters, gas-fired, currently represent just flow model.

Classification by type of ignition

  • automatically.She lights up when the water is turned on.
  • Semiautomatic.It is lit pilot light.

Types of columns depending on the power

  • High power.In these models, the power will be greater than 25 kW.
  • moderately.Their power range is represented by figures 20-24 kW.
  • Low power.power parameters in such devices does not exceed 19-20 kW.
High Power geyser High Power geyser

speakers also classified by the method of combustion.They are divided into units with open and closed chamber.In the first case, the air for supporting combustion device takes the room.The second embodiment presented turbo heaters, which has a blower and a combustion chamber are closed.

ignition types

main burner in modern speakers can burn from:

  • electrical impulses that create a piezoelectric element after pressing.Such an ignition is quite expensive, because inside the heater is lit the wick.The gas flow in such a device is increased by 25%.
  • under the impulse of the batteries.A spark in this column is produced during switching devices, and as soon as the device is switched off, the burner goes out, too.
  • Because of momentum caused by the work of the hydro generator.This method of ignition occurs in models from Bosch.For it is necessary to switch the electric generator, the operation of which is activated by the flow of water.
  • mains.This method of ignition used very rarely and depending on the availability of electrical sockets close to the column.

Also, there is a manual type ignition with a match or lighter, but in most models of heaters sold now it is not used because it is considered obsolete.

exchanger types

Most speakers that are presented now on sale, the heat exchanger is made of copper. The quality of such a heat exchanger affects the percentage of impurities in the copper (low-quality metal gray color will be different) and features spikes (dark spots indicate the manual soldering, is less quality).It is best to choose a model with an ultrasonic soldering copper heat exchanger.

Performance

this option for most manufacturers is measured in liters per minute, and is directly connected to the power unit. He indicated either on the back of the column or in the documentation on it.According to this indicator, you can determine how much water can be heated chosen model within one minute.

Schedule performance geyser

to correlate this data to your needs, keep in mind that an average of one faucet runs for 1 minute is about 7 liters of water.So if you need the same time to get hot water from two taps, pick equipment with a capacity of 13 l / min and higher.

water pressure

The technical characteristics of the column indicates the minimum water pressure at which the unit will operate. This option is especially important for residents of old buildings, where water pressure is low.

problem of water supply in Russian homes also advocates periodic occurrence of water hammer.Devices that can withstand 12 bar, is well tolerated, such short-term increase in pressure.

power modulation

Due to the water pressure drops Work column may be broken, but no differences will not prevent the operation of a model in which there is a modulation option. In this column at a water pressure drop equipment will continue to operate, maintaining a stable temperature of water coming from the tap.

This modulation is possible only in a certain range - it does not exceed the upper limit of the maximum capacity of the column, and the lower impact sensitivity of the internal elements of the device.If such a range would be 40-100% of the capacity of the column, this modulation will be comfortable.

presence of security sensors

safety of using the column depends on such sensors:

  • Burning. It will shut off the flow of gas if the flame attenuation.
  • ionization. This sensor will also block the flow of gas in a situation where the fire was extinguished.
  • Stream. Provides switch column after opening the tap on and off when the tap is closed.
  • overheating. With this sensor the water can not scald, but in the heat exchanger will not be collected scum.
  • water temperatures. This sensor detects, cold or hot water, resulting in a regulated flame power.
  • Traction .The column will stop working when there is no draft.
  • Protective reset .Fires at excessively high pressure water.
  • reduced pressure.Do not give include column when there is insufficient water pressure.

What options are ideal for apartments?

Choosing a column for a city apartment, the main thing is not to hurry, but to consider all important to choose the right nuances:

  • Decide on the power of the heater.Conventionally column with a capacity of less than 20 kW is suitable only for a water intake point.It is suitable if you only look for a model for the kitchen or bathroom only.If you need a device to supply water to two points, keep an eye model with a capacity of not less than 20-24 kW.
  • Choose ignition device type and version of removal of products of combustion.It should be considered whether there is a chimney in your home, as many output devices combustion products through it.However, there are also models, ejection of combustion products in which there is a right on the street.
  • Ensure the safe use of the column.
