Installing the storage water heater with your own hands: a step-by-step guide to those.norms
For owners of suburban property organization of an autonomous water heating system is almost a necessity. After all, agree, what kind of comfort can we talk about if the house has no hot water? Electric devices for water heating are extremely popular in the organization of autonomous water supply of a private home.
Such devices can also be used in apartments so that there are no problems with hot water. They cost a lot, so installing a storage water heater with their own hands will allow you to significantly reduce costs.
In this material we will talk about the rules of installation of these devices. We will tell you how they work and what you need to know before starting the installation. Also in the article you will find diagrams that allow you to properly perform the installation of the storage water heater. For clarity, the article contains videos with tips on installing heaters.
Choosing a boiler. how many liters you need
We decided to address this topic because of the volume of the water heater depends on the normal provision of a house with hot water (in short. DHW). Buying a tank with a large supply of water also makes no sense:
- Increases the time of heating to a comfortable temperature;
- The price of the equipment rises;
- Complicated installation of the storage water heater because of the large weight of the device a decent volume of water.
Advice. If the heater is needed only for washing dishes, it is better to buy an electric flow model of low power, which is placed under the kitchen sink or instead of the faucet. How to choose the right electric water heater for dacha, read in a separate publication.
Capacity of the storage tank is chosen according to the flow rate of mixed (warm) water per resident per day. 20 liters for hygienic needs and another 12 liters. for domestic needs. How many liters of boiler are needed in the end:
- In the economic consumption of the family of 2 persons enough 50 liters, comfortable. 80 liters;
- 3 people 80100 л;
- 4 members of the family. 100 120 liters;
- 5 or more tenants who actively use hot water. 120 150 l.
Discharge via safety non-return valve
This method is recommended to use all the well-known manufacturers of water heating tanks. Ariston, Thermex, Gorenje, Electrolux and so on. Household appliance is connected to the water supply according to the diagram (shown above) from the instruction manual:
- A safety group for boilers is installed on the inlet connection;
- In front of the group is placed shut-off valve;
- Valves at the outlet pipe are not provided or a ball valve is installed.
Explanation. Safety Group. it is an automatic element 3 in 1, it includes a valve reverse safety drain valve with a plastic lever.
Sometimes there are valves without a lever. you can not drain water through it
- We block the water main inlet in the apartment, turn off the heater from the mains.
- Let out through the closest faucet 1-2 liters, opening the valve DHW to the end. Leave the plumbing device in the open position to allow air to fill the void in the tank.
- We put a bucket under the “spout” of the valve, turn the lever and slowly empty the tank.
You do not need to disassemble the heating device before emptying it and wait for the water to cool down. Disadvantages of the method:
- Because of the small cross section of the spout (5 8 mm) water runs out too slowly, the boiler for 80-100 liters will empty in about 2 hours;
- The valve is often clogged, poorly flowing liquid;
- Sometimes the safety group gets jammed, the drain does not work at all.
The method is suitable for small water heaters 25-50 liters, provided that the valve valve is functioning normally. It will take too long to drain large volumes.

How to install a flow-through non-pressurized water heater
Choose a place to install
Unpressurized flow heaters, as a rule, can provide only one point of water extraction, so there is no question about the choice of location. Install the appliance in place of the faucet on the washbasin in the bathroom or kitchen, as well as next to the tap in the shower.
Drilling and Installation of Vertical Geothermal Loops
Secure the water heater
The faucet form factor appliance is the easiest to install. To do this, turn off the water at the faucet and remove the flexible hoses from the faucet. Unscrew the faucet mounting bracket and remove from the sink.
Assemble the water heater according to the instructions: attach the spout, screw in the inlet fitting and insert it into the hole in the sink. Screw on the mounting nut and tighten it to secure the flow cell.
Wall-mounted models have to be mounted on wall plugs or screws, depending on the type of wall. Using a template or by measuring the distance between the brackets, make a mark and drill the holes. Secure the water heater with dowels or screws.
Make a connection to the water supply
This one’s easy, too. Connection is reduced to the connection of flexible hose, which you removed from the faucet, on nipple of the water heater. Put a rubber gasket under the coupling nut and tighten it first by hand and then with a little effort using a wrench.
You can power a wall-mounted flow heater from the same flexible connection of a faucet or a shower. To do this, unscrew the shower head from the hose and connect the free end to the heater inlet.
Important point! There must not be any shutoff valves after the water heater. The water is only shut off by the flowmaker itself or by the faucet to which it is connected. Otherwise, due to the lack of flow, the heating element can overheat and fail.
Connect to the mains
Compact non-pressure models usually have a pre-wired plug, so the connection is simply a matter of inserting the plug into a grounded socket. Since the water heater refers to powerful devices, do not connect it through tees and extension cords. Because of the high current contacts in them can overheat, melt and cause a fire.
Carry out a test run
Turn off the tap on the hot water riser pipe. Open the faucet and run water through the appliance. Wait a few seconds for a steady stream of water. Turn the device in heating mode by turning the lever or by pressing the button. Check that the water heats up.
In fact, there are not many reasons to buy a water heater, but they are all valid and have a direct impact on the comfort of living. Take a strong-willed decision and equip your home boiler will make the annual “hello” from utility companies in the form of two-week preventive maintenance, or the lack of hot water in the cottage or country house.
A new trend in recent years, actively gaining popularity online and taking hold in people’s minds is the DIY (Do It Yourself) movement, which literally means “do it yourself”. The “consumer society” is gradually outliving itself, which pushes people to do the work they didn’t do before. And, paradoxically, many of them successfully achieve their goal. After all, the motto of a true craftsman is: “If you want something done well, do it yourself!”
Installing the water heater does not imply any insurmountable difficulties, so you can do all the work yourself. Why not prove to yourself and your environment that you can work not only with your head, but also with your hands? We will begin, as usual, with the theory, but the practical part the reader will have to do yourself. according to our instructions.
The purpose of the boiler is to heat water. By design they can be divided into:
Can a vertical water heater be installed horizontally
In summer without a water heater can not do. In city apartments the hot water is turned off, and in the country house it is not at all. Accumulation water heater installation over or under the faucet. Can the boiler be placed below the kitchen floor??. Home and garden. Daily updates, fresh and interesting information about modern technology.
Can the boiler be installed lower than the faucet.
At the moment there are a large number of ways to organize hot water supply in the country.
Installation. It is necessary to securely fasten the tank with water to 100- or 200?A liter tank full of water does not fall on your head. Water should always cover the heating element, if any, to avoid at least its burning out, and in the worst case. human electrocution or fire.The subtleties of choice.
Advantages. Easy installation, relatively low cost and in the case of heating the tank by the sun is also complete independence of any energy sources, well, of course, except the sun.
Disadvantages. The water temperature is usually low, it takes a long time to heat up, and in cloudy weather and in the absence of electricity. it is impossible to heat water at all. In addition, the contents of the tank cools down quickly (the result of lack of thermal insulation).
Apparatuses called storage electric water heaters retain heat well. They’re also called boilers. The essence of the idea that the heated water tank is encased in a good insulation, which allows you to keep the water heated for up to several days (cooling rate for different models is approximately 0.5-1 degrees per hour). These devices require not only electricity, but also the water supply. True, it should be noted that their installation is also allowed where there is no water supply, but then it must be simulated by yourself. install a container of 200 liters or more above the water heater at least half a meter to create the water pressure needed to operate the heater. Storage water heaters are constructed as follows: a container of ten to several hundred liters, made of stainless steel and coated inside with corrosion-resistant coating. Heating element, thermostat and special magnesium rod are inserted into the tank from below on the flange, which during operation of the heater is gradually dissolved in water, additionally protecting the tank walls from corrosion (by filling microcracks in the enamel). And also in the tank from below are two tubes. a short one for the cold water supply and a long one for the heated water outlet. Cold water is not just led to the water heater, but through a special reducer, which has several valves to protect the water heater from overpressure in the water supply, from water hammer, etc. п. As a rule, storage heaters have water heating regulators, allowing you to set the desired temperature precisely. The service life of the storage heater. up to 7 years and more, and
Choice subtleties. When choosing a model, pay attention to whether it is possible to replace the magnesium anode separately, without removing the flange with a heating element, which makes this periodic procedure much easier (replacement takes about 6 months to 4 years, depending on the model of the heater).
place the water heater strictly according to the manufacturer’s recommendations: horizontally or vertically; install it as close as possible to the place of hot water use in order to reduce heat loss in the pipes; do not install a check valve at the water heater inlet without a safety-draining valve; leave room for electric water heater maintenance. the distance from the protective cover to the nearest surface in the direction of the axis of the removable flange must be at least 30 cm. for models for 5-80 liters, and 50 cm. for 100-200 liters;try to find out whether the water supplied to the heater meets the standard for tap water, and if not, you must install a filter at the water heater inlet, which type and parameters can be selected by a service technician.during installation, do not apply excessive force to connectors, so as not to damage them and damage the fan coating of the inner tank; it is imperative to provide for disconnection of the heater from the mains for maintenance and in case of prolonged interruptions in its use; it is necessary to use the wires and connectors designed for the parameters of the power consumption of the device. Connect the power supply according to the phasing specified in the heater’s instructions.
Safety precautions. Categorically not recommended to use the services of unqualified installer who has no idea about the generally accepted rules of installation of water heating equipment. If the water heater is hung on the wall, be sure to commensurate with its strength with the total weight of the heater with water, so as not to collapse the wall. Make sure the electric water heater is filled with water before turning on the power.
Advantages. You can make it so that hot water will flow to several points at once (in the kitchen and in the shower). Low power consumption, consuming on average 1.2-2.5 kW per hour. Able to keep water heated for a relatively long time.
Disadvantages. Water is not heated immediately. for example, even a 10-liter unit with a capacity of 1.6 kW heats water from 15 to 77 ° C for 30 minutes. And the models with a volume of 100 or 150 liters requires from 5 to 8 hours to bring the water to such a temperature.
Boiler Working Animation
Where there is electricity, but no piped water is quite suitable electric water heater. It is a container, usually made of stainless steel (but there are also small models made of plastic), with a capacity of 10 to 120 liters, in which a heating element (1.25-1.5 KW) is installed, equipped with a thermostat (which allows you to maintain a predetermined temperature of water) and an outlet valve. Water in it is heated to a temperature set at the thermostat (ranging from 20-70 degrees), and this temperature is kept by thermostat. The time of water heating in such heaters, for example to a temperature of 65 degrees, is about one hour. Depending on their capacity, material and manufacturer.
Disadvantages. Dependent on the electric grid. Thermal insulation of the tank is usually missing, which leads to a rapid cooling of water after power off.
The height of the water heater for 50 liters
A relatively small 50-liter water heater is placed in the bathroom or toilet above the toilet. In cramped conditions withstand at least 0.5 meter from the bottom nozzles to the floor surface, so you can connect a hose, put a bucket, take out the heating element or a magnesium rod. In the toilet the recommended distance from the toilet bowl lid to the bottom of the boiler is at least 1 meter.
80 liter vertical storage heaters are mounted on two bracket supports fixed in a solid wall made of concrete or bricks. Location level is chosen by location, taking into account the height of the ceiling and the boiler. As a standard tank is located so that the distance from its top plane to the ceiling was 10-15 cm, and the bottom was elevated above the floor at 1,5-1,8 meters. It is convenient for maintenance, adjustment and cleaning.
Conclusions and useful video
On the correct installation of water heating devices depend on the work of DHW and heating system, so it is important to consider all the installation nuances. A few practical tips are presented in the videos.
Recommendations for self-assembly:
It is always advisable to monitor the installation carefully, referring in parallel to the documentation accompanying the installation of a specific boiler model.
Often users install the system without bothering to look at the enclosed diagram. Connect the two water pipes and insert the plug into the socket. such actions seem to be commonplace for them. But technology does not forgive mistakes.
