If there is no hot water in the house, you can not wait for it to appear, but resolutely take matters into your own hands. Manufacturers offer a whole range of water-heating appliances, designed for a variety of requirements for them, their operating conditions and the financial capabilities of consumers. Moreover, this technique is so functional not only in the process of use, but also during the installation, that this operation is completely within the power of the home master.
Choice of water heater
Heaters of two types are most demanded today: flowing and accumulative. They are adjoined by less used ones: of the hybrid type, of flow-accumulative and mainly of the dacha-type, of bulk.
In addition, these types of heaters are also divided by the method of heating. Some use electricity for this, while others use gas.
Which of them is better and which is worse is impossible to say right away, because much depends on the need of a family for hot water (that is, its volume and frequency of use of the device), on heating methods, on the state of electrical wiring and gas communications, even from the fortress walls on which water heaters are mounted. And, of course, from the financial possibilities of the consumer.
Did you know? The first water heaters, which had a remote resemblance to the current ones, appeared in the 13th century, and the first electric water heater was invented in Germany in 1885.
Accumulative electric
Electric storage heater, also referred to as a boiler, is also of relatively modest size with a volume of 30 liters, and very impressive volumes of 300 liters. Inside the boiler there is an electric heater in the form of a heating element, that is, a tubular electric heater, or in the form of a spiral heating element. 
The principle of operation of the boiler is quite simple. It contains a certain amount of water, which, under the control of the thermostat, is constantly in a state heated to a pre-set temperature.
High-quality thermal insulation around the boiler tank reliably retains heat, allowing it to lose only 0.5-1 ° C per hour. When over time, or when using hot water from a boiler and compensating it with cold water from a connected water supply, the temperature in the boiler drops one degree, immediately the thermostat turns on the heater, which heats the contents to a temperature one degree higher than the set one.
As a result, the storage water heater allows you to always have on hand hot water of the required temperature at any time of the day. The advantages of boilers include the ability to include them in a simple electrical outlet without laying special wiring. 
It is also important economical cumulative heater, which per hour uses as much electricity as it consumes an average vacuum cleaner.
The possibility of distributing hot water from the boiler installed in the bathroom to the kitchen is also useful in the household.
To arrange your home, familiarize yourself with how to remove old paint from the walls, pokleit different types of wallpaper, put the light switch and socket.And the lack of a boiler is only one, but very visible. Its awesome dimensions do not always fit harmoniously into the cubature of the bathroom. Trying to solve this problem, designers of accumulative water heaters resort to different solutions, the most popular of which now is a flat boiler.

Flow electric
Unlike accumulative, a flowing water heater does not accumulate water and does not store heat, but reports it to water directly from the water supply system. Therefore, its size is small.
The principle of operation is the passage of tap water through a small tank with a spiral-like heater, in which it is heated to the temperature set on the thermostat. And the whole process is controlled by a flow sensor, which, when opening a water faucet, records the beginning of the movement of the fluid and immediately turns on the heating element. When the valve is closed, the heater naturally turns off immediately.
Consider in more detail how to install the instantaneous water heater yourself.The main advantages of flow heaters usually include their small size and fast heating. If, when connecting a boiler, one has to wait for a long time before water accumulates there and heats up, hot water starts running from the flow heater in half a minute, in a maximum of a minute.
In some cases, a serious advantage of this type of heater may be their ability to produce hot water in unlimited quantities, whereas in boilers this quantity is limited by the volume of the tank.
The rather low price of the instantaneous water heater also refers to its advantages, which, however, are quickly leveled during operation due to increased electricity consumption. So here the initial plus is quickly absorbed by the subsequent minus.
The relatively high power of such heaters requires separate wiring equipment, which complicates their installation. 
Gas flow
This type of heater is familiar to many and is popularly referred to as a gas column. When the valve is opened, the gas in the burners of the apparatus automatically lights up, which heats the liquid passing through it.
In the gas column installed thermostat, with which it is possible to adjust the desired water temperature at the outlet of the apparatus. Automatic adjustment of the force of the flame occurs depending on the pressure of the water passing through the apparatus at any given moment. 
The geyser does not take a lot of place and is compactly mounted everywhere where there is a gas eyeliner. Its great advantage is the very rapid production of hot water immediately after turning on the tap.
However, a serious disadvantage of this device is its dependence on gas pressure of at least 12 mbar.
Did you know? The first device, known to us today as a gas column, was invented in England as early as 1868, and in 1889, the first accumulative automatic water heater working on gas was created in the USA.
Gas storage
Gas boiler on the basis of its work is similar to an electric one. In his tank - as a rule, a large volume - water also accumulates, which heats up to the temperature set on the power regulator. Thanks to high-quality multi-layer thermal insulation, the boiler is able to retain the accumulated heat for up to a week, not including the gas burner.
It will be useful for owners of country houses, summer cottages, as well as residents of the private sector in cities how to make a path from wood cuts, concrete paths, build a formwork for the foundation of the fence, make a fence from gabions, fence from a chain-link grid and build a veranda with your own hands.Unlike the instantaneous water heater, the gas boiler is capable of operating at low gas pressure.
On the other hand, the amount of hot water produced by a boiler at one time is limited by the volume of its tank. If, for example, someone has spent on their needs all heated in the tank, then wait until the next batch warms up, will have at least an hour. The flow heater has no such problem.
Another significant drawback of a gas boiler is its large dimensions, which require both sufficient space for its installation and sufficient strength of the wall on which it is installed. 
Bulk electric
This type of heater is designed for places where there is no water supply. Most often it is successfully used in country houses. The principle of its operation is extremely simple. Water is poured into the tank through the hole on top of the lid. Inside the tank there is a heater with a thermostat, and outside - thermal insulation.
When the water inside the tank heats up to the set temperature, the heating element turns off. It turns off even if the liquid in the tank drops below the minimum mark. 
The advantages of this type of water heaters should include their simplicity, compactness, the ability to work in the absence of plumbing.
A small volume of the tank and the need to frequently add water by hand, of course, should be attributed to the shortcomings.
One of the main elements of the improvement of a private house is water supply. Read how to make water from a well in a private house.Usually, for example, for taking a shower, this heater is located above the head of a person, and water flows into the shower hose by gravity. But there are models where a special pump is mounted, which increases the pressure. However, this requires a tank of substantially larger volume.
Choosing a location and location
If the transportation of flow and bulk heaters is not very difficult due to their relatively modest dimensions, the transportation of large-sized boilers requires some caution. The manufacturer’s instructions require them to be transported in a vertical position, because, despite the high-quality original packaging, in a horizontal position, the boiler during transportation can damage the outer casing or the temperature indicator.
The choice of location in the house where the heater will be located depends largely on the type of apparatus and the location of water and gas sources. However, in any case, there are general rules that recommend placing the heating equipment as close as possible to the places of maximum hot water consumption. In addition, the devices should be positioned so as not to interfere with the movement of people inside the room and at the same time be available for maintenance. 
Special requirements for the place of their installation impose cumbersome and heavy boilers. The walls to which they are attached must be capital and withstand a weight equal to twice the weight of the apparatus filled with water.
In addition, the cumulative water heater should have on both sides a quarter of a meter and at least 10 cm from the ceiling free space for air circulation. Also, in order to avoid collecting condensate leading to corrosion, it is recommended to warm the supporting wall. 
Installation of filters
Any water, be it tap or well, inevitably contains impurities which, over time, are capable of causing significant damage to the internal elements of the water heating equipment. Therefore, it is strongly recommended to put a deep cleaning filter on the water inlet system. Its installation will be much cheaper than repairing or replacing the entire heating system in a couple of years.
Purchasing the necessary tools
For installation of a boiler or other water heaters tools will be required:
- perforator with drills not less than 10 mm in diameter;
- adjustable wrench;
- roulette;
- cutting pliers;
- pliers;
- screwdriver.
In addition, the following materials will be required:
- tow;
- sealant;
- FUM tape, commonly referred to as silicone;
- two shut-off valves for flow or three for storage heater;
- two or three tees respectively.
Tow 
SealantIn the absence of the supplied flexible hoses, they will also have to be purchased in the amount of two pieces.
Installation of fastening systems and fixing the water heater
Due to its solid dimensions and heavy weight in a state filled with water, which both the wall and the fastening system must withstand, the installation of the boiler is the most difficult.
Each unit is equipped with a support plate welded to the rear of the case with mounting holes. In order for these holes to coincide as accurately as possible with the anchor bolts or plastic dowels to be installed in the wall, it is necessary for the two to attach a strictly horizontally empty boiler to the wall and mark on it where the holes will be drilled. If the installation has to be done alone, you need to use a tape measure. Measurements must be made extremely carefully, with an accuracy of a couple of millimeters. 
Installation of fastening systems
When the future holes are marked, the wall should be drilled to a depth of at least 12 cm. For anchor bolts, the depth can reach 15 cm. Then, anchors or dowels are inserted into the holes, respectively, into which bolts or hooks are screwed. The bolts are screwed through the holes in the boiler support plate, and the hook is simply hung on the hooks.
Important! It is not necessary to use plastic dowels for fixing a boiler with a volume of over 50 liters, for this purpose it is necessary to use only anchor bolts.
You can screw in between the two screws already screwed in and lower them another additional screw on which the lower part of the plank will rest. This will prevent its deflection. 
Screw the additional screw
Hose connection
To connect the water heater to the water supply system, it is necessary to screw the adapter in the bottom hole with a thread marked in blue into the adapter, which is popularly called "American", on which a tee should be attached. It is necessary to fasten a drain valve to the side of it, which will be required if for some reason you have to empty the heater tank.
To the bottom of the tee is necessary to attach a safety valve that protects the device from excessive pressure or overheating. Then a tap is connected below that blocks the access of tap water to the unit. 
Safety valve
To another hole of the heater, marked in red, connects a tap that opens or closes the hot water outlet from the apparatus.
After that, the faucet for cold water is connected to the water supply system using a flexible hose, and the faucet for hot water is connected to the wiring supplying hot water to all the necessary points in the house with a high-temperature hose.
Pipe liner
In the absence of the connection points to the plumbing and domestic heating plants, they should be created. If the system consists of metal-plastic pipes, then the pipe is cut at the required place and a tee is installed on it with the help of a corresponding fitting, to which a water heater with a safety system already mounted on it is connected with the help of a flexible hose. 
Tee
Due to a not very presentable appearance and a short service life, plastic pipes are losing their former popularity today.
When the system is equipped with polypropylene pipes, the connection to them occurs by cutting a small section out of the pipe and plunging it in return with a special soldering iron with a tee adapter. This method of tapping into the system is considered the most reliable.
Harder to crash into a system consisting of metal pipes. A small area should be cut in the pipe, then a thread is cut at both ends and a tee is inserted with the help of a sanitary coupling or sgon. 
We insert tee
Drainage tube connection
On the safety valve, which should be installed on the boiler, there is a small pipe through which water is discharged in an emergency. During normal operation of the apparatus from the nozzle, water slightly leaks, which indicates a good condition of the valve.
To prevent water from dripping onto the floor, a drainage tube is put on the branch pipe, which often uses a tube from a medical dropper. The end of this tube can be diverted to a bathtub, a nearby sink or to the toilet flush cistern if the boiler is installed in the toilet. 
Drain tube
Checking system connections
Когда бойлер подключён в полном соответствии со схемой, приведённой в заводской инструкции, следует проверить качество всех подключений. Резьбовые соединения, осуществлённые с применением либо пакли со специальной уплотнительной пастой, либо с помощью ленты ФУМ, должны обеспечить высокую степень герметичности.
With the onset of cold weather, the thermal preservation of the room begins to trouble us. Learn how to insulate the window frames for the winter with their own hands.How well this turned out in practice can be seen by filling the boiler with water. To do this, on one of the mixers connected to the home water system, turn on the "hot water" position. Then it is necessary to open the cold water tap, as a result of which water will start to flow into the boiler's tank, and air will be forced out of the open mixer from the open mixer. After the air is replaced by water, the mixer must be closed.
If there are no leaks in the joints, then the installed device is ready for full-fledged work. 
First start
Connecting the device to the electrical network and turning it on, you need to put on it the indicators of the heating mode and fix the initial indicators of the temperature indicator. After a quarter of an hour you should check these figures. If they grow, then the heating element is working normally.
System prevention
As practice shows, the optimal heating lies in the range of 55-60 ° C. At this temperature, scale builds up more slowly on the heating element and prevents the appearance of mold. It is also recommended to raise the heating temperature to 90 ° C for 1-2 hours weekly to prevent the appearance of bacteria in the storage tank.
Important! It is not recommended to set the temperature in the boiler at 30-40 ° C, since it contributes to the rapid development of bacteria inside the apparatus..
Before each start of the boiler it is necessary to check the presence of water in it. Every year should be removed from the boiler tank scale. You also need to constantly monitor the normal operation of the anode, which sometimes has to be replaced if necessary.
So, with some skills in handling tools and the availability of the tools themselves, as well as with due care and patience, installing water heaters on your own, including cumbersome boilers, is not something that cannot be solved. More and more house craftsmen prove it in practice.
