Owners of country houses, cottages and just suffering in periods of hot water to disconnect people can appreciate the advantages of a home water heater. Thanks to this device, you can protect yourself from a sudden disconnection of warm water and use it in those moments when it is necessary, without waiting for the completion of the repair work. In country houses such an acquisition turns out to be completely indispensable! If you decide to join the number of happy owners of cumulative water heaters, you first need to clarify a few questions. What suitable size of the heater to choose? After all, it is precisely that it depends whether you can comfortably enjoy hot water without excessive costs of excessive volumes of water.
Before buying a boiler, you need to decide on its volume.
The required amount of boiler is depending on the number of simultaneous or taking place through very short intervals of water consumption.
You can select 3 factors for which you should pay attention to when determining how the heater is to select:
The volume of boilers primarily depends on the premises where it will be installed.
- The purpose of using hot water. Hot water can be used for different needs. If you plan, for example, only wash the dishes, then the flow will be very small, and a blank size boiler is required to receive baths. Also, the cumulative water heater is installed in case of a sudden disconnection of hot water, for this prefer to choose a small scaber.
- Consumers of hot water are those devices that are connected to the water heater. It can be: a faucet in the kitchen, a shower cabin, a bath, a tap in the bathroom, a jacuzzi, etc. For each device there is an approximate water consumption on the use session, the numbers will be shown slightly below.
- The number of people at the same time living in a house or apartment where a boiler is installed. This is, of course, the main factor affecting the number of hot water consumed. Regular bathing and soul taking, washing dishes, multiplied by the number of tenants, will give a general idea of the necessary amount of hot water.

How to determine the consumption of hot water?
Boiler installation scheme.
To solve this issue, you need to take the most active period of consumption of hot water per day and calculate how much water was used. Usually, this period is the morning hours when adults are rushing to work, and children are going to school, because everyone needs to take a shower, clean your teeth and eat, and maybe even, after this, wash the dishes. Consumption for such a period of active, almost continuous use of hot water and it will be the most necessary heater volume . In addition, it is worth a small supply to this figure. Consider some common calculations.
For one person, which uses the shower and kitchen sink for washing dishes, it is enough to choose a small heater for 30 liters. This option is also suitable for installing a boiler to "every case". For a family of 2 people hosting every morning of the shower, the amount of accumulative water heater is required of 50 liters. And for 3-5 tenants in the same conditions it will be necessary to choose a boiler with a water margin of 100 liters. You need to take carefully to the adoption of baths, as this is the most consuming moment in all water use and one-time bath adoption can turn into 100 liters of hot water.
More accurately indicates hot water flow indicators in the following table.
| Consumer of water | Water consumption (l) | Average temperature (degrees Celsius) | Water consumption 60 degrees (L) |
| Sink | 10 - 20 | fifty | 8 - 16. |
| Bath | 150 - 180. | 40. | 90 - 108. |
| Shower | 30 - 50 | 37. | 16 - 27 |
| Sink | 10 - 15 | 37. | 5 - 8. |
| Sink for hand | 2 - 5. | 37. | 13 |
Water Heater Installation Instructions
List of tools and materials:
(Carefully inspect the package of your boiler. Some materials can already be included.)
The sequence of fastening an anchor bolt.
- Perfederator or shock drill;
- anchor bolts;
- Pliers or key screwing bolts;
- level;
- Cumulative water heater;
- 2 ball valves;
- explosive reverse filter;
- pressure regulator;
- pipes or flexible hoses for connecting to hot and cold water supply;
- UZO (protective shutdown device).

First you need to select a place under the water heater. Usually it is a wall of a bathroom or toilet, since such a location allows without excessive work to connect a boiler to the water supply system. Less often, the accumulative water heater is installed in the kitchen. It is necessary to place on the wall in such a way that it is separated from the ceiling at least 10-15 cm. The wall should be overhaul. It is forbidden to mount the water heater on plasterboard walls and partitions, due to the rather large weight of the filled boiler, especially if its volume is close to 100 liters.
Accordingly, the calculations are noted the places of the upper fasteners. The horizontal fastening line is evoked by the level. In the places of fasteners, the holes are drilled by a perforator or a shock drill where the anchor bolts are screwed.

Now you can make a trial installation of the heater. If the boiler got up smoothly and in the desired place, it is removed and drilled by the rest of the fasteners (amount 1 or 2), located at the bottom, followed by screwing the anchors. After that, the boiler is again mounted on the mounts.
A mounted accumulative water heater must be connected to water sources. For these purposes, it is best to use pipes (metal or plastic). If this option is not suitable for any reason, flexible hoses come down, but due to their low bandwidth, it will be difficult to use hot water for 2 consumers at the same time, for example, to take a shower and wash the dishes.
A boiler connection with hot and cold water pipes must be made through ball valves. This is necessary in order to disconnect the boiler from the water supply system when necessary.
To the cold water pipe, the heater is connected via the reverse explosive valve and pressure regulator. The check valve is needed to regulate water pressure in the boiler. If you do not do this, the boiler can explode from high pressure inside the tank that appears when heated cold water. In addition, the reverse explosive valve prevents the heated water from entering the pipe with cold water. The pressure regulator serves to reduce the pressure of cold water entering the boiler. This value should not exceed 6 kg per square cm. If the pressure in the cold water pipe exceeds this threshold, then the installation of the regulator is required. The order of connecting devices to the cold water supply in the direction from the pipe to the boiler is as follows: the pressure regulator, then the ball crane, after which the explosive reverse filter, the pipe from which will lead to the heater.

After connecting the heater to the water pipe, the boiler must be connected to the power supply. Due to the high electricity consumption by heating elements inside the boiler, it should be connected to a good wiring. If the heater is not equipped with a built-in Uzo (protective shutdown device), then it will be necessary to put it in the electrical switch on the power line to which the water heater is connected. Also be sure to connect the heater to the outlet protected from moisture.
Features of water heaters
In appearance, accumulative water heaters are divided into 2 types:
- Vertical. The boiler of this type is stretched vertically and is also vertically installed. The heating element (TEN) is at the bottom of the tank, which provides the highest water heating. It saves on electricity and win time.
- Horizontal. The horizontal boiler has a horizontal housing with a tan, located on the side, which significantly reduces the heating rate of water.
The material from which the tank is performed is important. The enameled tank copes well with water with a high content of iron, since they have large protective anodes. When operating a boiler with a tank made of stainless steel in such conditions, you should use special cleaning filters.
Water heaters, depending on the number of Tannes, vary by power consumption. If it allows power supply, then water heaters with two heating elements can be used.
