Hot tap water has become almost symbolic concept, determining the level of civilization. Not everywhere, but, have access to the public network. A natural solution to this situation are boilers for the home. Proven in buildings where access to the public network is difficult. To select the right heater for water, should familiarize themselves with the, you have to choose from.
Kinds
Main concerns a method for the separation of water heating. Hence, two types of water heaters:
- capacitive
- flow

The choice should be limited by several factors. In the case of capacitive heaters water is heated in the tanks, and is stored in them. Depending on the volume, online store Allo, you can buy a boiler of hot water which can satisfy the needs of a large family, and a person who lives alone.
The main advantage of this type of device is a high comfort of use. Boiler (tank) It has an insulating layer, which allows to maintain the set through an oven for many hours.
They are divided into:
- under pressure
- without
For the first type, you can connect the taps around the house or apartment (multi system). Unconfined designed for a single point of water consumption (odnotochechnaya system).
Water heaters under pressure have a much greater capacity - up 200 liters. Free-flow often have small tanks - 10 – 15 liters.
The disadvantage of capacitive heaters is the need to allocate space in the boiler (some very large). Therefore, in very small apartments of their installation is not always justified.
Водонагреватели проточные
Flowing water heaters heated running water, typically tap in one place, eg, bathroom. If you want to have hot water in the kitchen, you will need to install a second heater. Their biggest advantage is the ability to install in a small space. Next to the crane or under the sink in the kitchen. Besides, instantaneous water heater installation costs are much lower.
Unfortunately, in the case of such a device, горячую воду нужно подождать некоторое время. Water heater stops working in the moment, when no water is flowing. After opening the tap, it shall, after closing – disconnected.
Another difference is the type of food. In this way, you can buy a device:
- gas
- power
gas
Gas fuel is relatively cheap, and to heat water on it through modern device is perfectly safe. Of course, if the heater is operated and maintained according to manufacturer's recommendations.
Heaters may be natural gas or liquid on nutrition. Each device is best suited for one type of fuel. However, there are models, which can be connected to both types of gas.
Combustion gas may be carried out in two ways - in open or closed chambers. Hence, two types - with cameras open and closed.
Some gas water heaters have the exhaust sensor. At that moment, when the air is too high concentration of carbon monoxide, cease to work. If you buy a water heater without encoder, such a device should be purchased separately.
Older articles brought into disrepute such devices. Quite often it came to the fumes poisoning, and even gas explosions. In the case of modern devices, in theory, таких ситуаций не должно произойти. But for this to be met certain requirements - in the first place, housing:
- Do not install in a room where people stay longer than two hours;
- Minimal cubage for gas cylinder with open combustion chamber 8 m3, с закрытой камерой – 6,5 m3;
- Minimum room height 2,2 m.
electrical
As the name implies, powered electricity, which more combustion gas obtained from. there is, but, one big advantage - there is no threat of poisoning by fumes.
As well, as well as gas, may be capacitive and flow. Deciding to buy an electric heater, you must know, they are divided into:
- Single-phase;
- three phase.
Single phase is most often used for houses and flats, weaker than the three-phase. The three-phase needed where there is a high demand for hot water. We need access to three-phase power supply.
Options
When choosing a water heater must take into account the following parameters:
- power;
- maximum / minimum pressure of water;
- capacity;
- maximum working temperature;
- Dimensions / weight.
Power
Here everything is clear - higher power, быстрее нагрет воду. Мощность может быть от 1,5 kw to 50 kw.
- Electric instantaneous water heaters from 2 kw to 25 kw. For houses and apartments enough 3 – 4,5 kw. If you use a lot of hot water, buy power from device 5 to 6 kw. Very high demand requires water heaters designed for three-phase power from 19do 25 kw.
- Capacitive pressure-free electric heaters – power from. 1,5 kw to 4 kw. Electric heaters capacitive pressure – power from. 1,5 kw to 2,5 kw.
- Gas instantaneous water heaters – power up 50 kw.
- Capacitive gas water heaters – power from 5 kw to 10 kw.
The maximum / minimum pressure of water
Parameter, basically,for instantaneous water heaters, which operate in a certain pressure range, refer to the instructions in the device.
Capacity
Option for water heaters Capacitive. Choosing capacity refer to the table below:
Maximum Operating Temperature
80WITH.
Dimensions / weight
When choosing the size and weight of the water heater should be considered a placement.
Manufacturers and prices
If you decide to buy electric devices check the offer of the following companies:
- Ariston
- Thermex
- Biawar
- Elektromet
- Siemens
If the choice falls on the gas heaters, should take into account the brand:
- Ariston
- Yunkyers
- Valiant
note! Подогревание воды газом выходит дешевле и более эффективно.
