How to choose a water heater for the house - optionally instructions

Household water heaters according to the process of creation of warm water is classified as:

- boilers for electricity;

- Gas heaters.

Electric "vodogreek" models work as well as tea, eating from a single-phase or three-phase network.Water heaters that use gas energy, connected to the backbone.Burning, the gas heats the heat exchangers, where the water, or warm fluid tank.

Global manufacturers produce a lot of water heater models.Among them, Bosch and AEGHaustechnik, Electrolux and Timberk, Ariston Thermex and many others.How to understand this diversity and to select the right heater for the house?

second classification - according to the process water circulation.All water heaters are divided into: a system with holding tank and flow devices, pressure and non-pressure.Parameters of the equipment and capabilities vary, being directly dependent on the type of unit.

1) Accumulative gas water heaters

water is heated in a water heater tank with the help of gas - the most economical way.But to put this unit can only be, if the apartment has gas main pipe.Durability and ease of use water heater storage type, it compensates for this relative lack as low pressure liquid.The only significant drawback referred to the fact that the room is required chimney lining.

2) Flowing water heaters Gas

Most often, they are called in one word - column.When there is a possibility of gas supply, it is the most convenient way to heat water.This type of "vodogreek" may differ from each other by firing.

• pezorozzhigom - column mounted piezo element, which creates a spark, inciting igniter.This is a good way to ignition: convenient and economical.
• Electronic ignition - the device ignites, taking the energy in batteries (batteries), change that requires no more than a pair of times a year.
• hydrogenerator ignition - means that the device takes energy from miniturbiny, which is driven by the activity of the flow of fluid passing.Speakers Work begins immediately with a tap opening.

choosing the gas flow "vodogreyku" should pay attention to its security.Necessarily should be a system that blocks the flow of gas if the pressure is low, damped burner or chimney suddenly discovered the problem.

Cumulative electric water

a device representing a tank capacity of 150 liters with tubular heaters.They are more commonly called boilers.The tank water is heated gradually, depending on the power of the device, the set temperature and tank capacity.On average,

total duration of heating is approximately 2 hours.If the water in the tank is used up, it will have to wait until it warms up.If you buy a water heater for the kitchen, it is sufficient capacity from 30 to 50 liters.For a family of 3 people is enough water heater capacity of up to 100 liters.And for a country house with some hot water analysis points required water heater capacity of around 200 liters.

least of the fact that an electric heater or heater should be easily replaceable in case of failure of the old.In operation very convenient, if the model is equipped with an electronic scoreboard with a temperature controller, specifying that one day you can no longer return to this question.

The device must be safe to operate.For this purpose it is equipped with a function of the RCD.Very convenient, if the model has a function to prevent boiling water and protection from the inclusion without water.

storage water heaters are ideal for home, they are economical and reliable enough.However, a serious disadvantage of these heaters is their bulkiness.Much smaller in size flow-through water heater.

Instantaneous electric water

Their operating principle is as follows: in a flask with mounted therein a heating element water flows, where it is heated.The volume of the flask about 1.5 liters.Choose a water heater for the house should be, depending on the power of the device.

To heat water for the kitchen appliance with the required capacity from 2.5 to 3.5 kW.To heat water for a shower with little pressure - Power 8-9 kW.For the soul with an average pressure of the device is required power from 9 kW.In winter, due to the very low temperature of the incoming water, the water heater performance is greatly reduced.The main drawback of such devices - it is their high power, sometimes require a standalone connection instantaneous water heater.The device consumes large amounts of electricity.

When buying instantaneous water heater for the house pay attention to the material of the heating element.Bare wire helix works without scale, even in hard water.The device must be reliably protected from moisture.

Pressure boilers

These devices are capable of withstanding pressures up to 1 MPa.Pressure water heaters should be equipped with reverse and bleed valves.These devices operate in combination with standard mixers.

Free-flow water heaters

Such devices are intended only for a single point of intake.They can not work together with standard mixers, and an en suite shower watering can and own crane.
