How to install the boiler with your own hands: photo and video instructions and step by step instructions
First of all, when installing a wall-mounted water heater, you need to make sure that the wall will withstand the additional load. Equipment manufacturers recommend taking four times the weight of the boiler filled with water in the calculations. But since few people can properly perform the calculation of the loads of building structures, you should be guided by the following rules:
- The supporting wall is capable of supporting the weight of almost any household water heater.
- When installing a boiler on the walls, especially in “Khrushchev”, or hollow brick walls, small-capacity tanks can still be hung simply on the anchors. or less capacious storage tanks are better to install on a wall, reinforced stanchions or mounted on through bolts, fixed for security by the coupler.
Mounting a storage water heater on the wall
Types of water heaters to install under the sink
Since the space under the sink is still limited, you can install it or a small-capacity storage water heater of 10-25 liters or flow-through. They heat up with electric heaters of open type or with heating elements. Gas boilers, as a rule, higher capacity and are made only for standard wall mounting.
They differ in the way the pipes are connected under the sink. on the top of the sink. When buying a heater you need to pay attention to this, otherwise the device for installation over the sink, installed under the sink will work badly and for a short time.
So what water heater is better. storage (capacitive) or flow (pressure)
Accumulation heaters take more space and cost more, but their power consumption is lower than in flow-through (up to 3 kW), and they can provide a larger volume of hot water per minute.
Accumulation water heater
Since the flow-through water heater has a relatively high for household consumption. up to 8 kW, you need to make sure that the electrical network in the apartment or house is able to provide it without constantly “knocking out” automatic machines. If the heater is designed only for the time of heating network pressure test when in summer the hot water is turned off for 2 weeks, the heating of 2 liters per minute will require a capacity of no more than 3.6 kW. Cold “winter” water will not get heated in this volume even to 30 ° C. For year-round consumption, either a tank water heater or a high-capacity flow heater is more suitable.
At the initial inclusion of the storage device will need some time to heat water, flow-through at once can heat from 1.8 to 4 liters per minute. They heat the entire flow of water at once, the storage tanks also heat the incoming cold water, which is mixed in the tank with the hot water when it is consumed, and after a while the water temperature in the faucet begins to decrease.
Flow-through water heater
That is, both types of water heaters have both advantages and disadvantages, and the choice in favor of one of them. only a matter of consumer preference.
But for a summer cottage, in the absence of mains water supply, non-pressurized water heater, which is equipped with a special mixer of small diameter to obtain a stronger jet is indispensable. It is equipped with a hydraulic pressure switch to create the head. If you do not use the cottage in the winter, you can even remove it, and then re-install it in the spring. it is so easy to install.
Boiler mounted on the wall
This version of the installation of the water heater is considered a classic. The boiler may only be attached to a load-bearing wall, and so that it is as close to the water intake point as possible.
Height of the device can be any. The main thing that it was convenient to use. Consider the step-by-step instructions on how to mount the water heater:
Additional storage tank
A frequent occurrence in dachas is the lack of a permanent water supply. This problem is solved by creating an additional tank to implement the water supply at a head and create the possibility of uninterrupted operation of the device for heating. This somewhat complicates the installation work, as well as increases the final cost of the heating system, but this output is the most effective way to replace the central water supply.
How an indirect hot water tank works
Additional tank, the number of liters, which exceeds the boiler itself, is suspended slightly above the device. The main requirements for the tank:
- Availability from the water channel, which is designed to prevent water spilling over the top of the additional vessel.
- Pressure relief valve.
- The float system of automatic water supply for filling.
- A valve designed to drain the liquid if necessary.
- Valve to cut off the flow of water in the boiler.
Important! When connecting the container is used metal-plastic pipes, which additionally installed a valve that blocks the water in the boiler, as well as a T-piece, which withdraws the circuit to the tap for cold water.
Tools and materials for installation
At independent installation of the water heater can not do without the use of various tools and materials. To perform this work you may need:
- An impact drill or a rotary tool with drills for concrete.
- A set of wrenches.
- Silicone sealant.
- Construction level.
- Fittings or adaptors of other designs (depending on the material of the pipes).
Attention! If before installing the water heater you need to reinforce the wall, you can’t do without cement or a special mortar, as well as tools for applying and leveling the mortar.
Features of fixing the water heater on a thin wall
Ideally, the water heater should be mounted on solid brick, concrete or block walls, because the device together with the water has a fairly large weight. But sometimes you need to hang the device on a thin plasterboard, frame, wood, gas concrete or foam concrete base. In this case, you will need to reinforce the wall and use special fasteners.
Directly on a wooden wall to mount the water heater can not be for fire safety reasons. First it must be well insulated from the heat, for example, profile iron, which is used for roofing.
In other cases, special fasteners are used:
If you plan to hang the water heater on the wall of foam concrete blocks, you will need metal dowels or special chemical (glue) anchors for foam concrete. A chemical anchor is a universal fixture that can withstand heavy loads. Environmentally friendly and resistant to low temperatures.
The expanding dowel is held in the wall by frictional forces in the expansion joint, and the chemical anchor. by the adhesion of a special adhesive
Fixing to the adhesive anchor is done as follows:
- Drill a hole with the expansion channel by turning the drill at an angle in different directions.
- Concrete dust is extracted from the hole.
- The hole is filled with a quick-hardening mortar, into which a fastening sleeve or threaded rod is inserted.
The resulting cone-shaped plug provides a fairly high strength fixing.
For installation in hollow constructions an anchor sleeve is inserted into the hole and the stud is screwed into it
Step by step instructions for installing the water heater
It is better to work with two people, if there is no such possibility, then call for an assistant, at least just for hanging the water heater.
Decide on the place of installation of the storage boiler, make a diagram of the arrangement of pipes. You will need to do a cold water inlet and hot water outlet.
The water heater will be installed here. Room dimensions according to the size of the boiler
We recommend the easiest and safest connection. At the inlet of cold water shutoff valve, followed by a safety valve complete with return flow. At the outlet of hot water valve is not necessary, for repair is enough to shut off one. If you want, you can put valves on every bend and on every pipe, but the result of such work will only be negative. In addition that will have to buy unnecessary items, will increase the time of installation and increase the number of places of possible leaks. Practice shows that all the other stop valves are never used, blocking is always only one inlet.
Important. Try to install the unit at a maximum distance from the shower or bathtub. In these places, it will fog up, making it uncomfortable during water procedures.

If you have new construction and in the wall are already made sockets of piping, the work is much simpler. And if the boiler is installed in an already operating bathroom? The water supply is best taken from the sink. Disassemble the connection at the cold water inlet and put a tee there. Connect the hot water to the existing faucet with a shower. You can perform these works quickly by using external laying of pipelines and flexible hoses, and you can drilled through the walls and hide the communications. The second option is much better, but requires additional effort. In addition, it is not always possible to restore the wall tiling in its original form. It is up to you to decide which option to choose.
Unpack the water heater and check for completeness. What must be in the supply is specified in the manufacturer’s instructions. There is also a rough installation diagram, too. From this scheme for you is important only one point. how to connect the safety valve. We already mentioned that it is located in the same housing as the return.
Materials must be purchased according to your connection diagram. Count their number and nomenclature, including the corners and ends. Use FUM tape to seal the connections. Not only does it perform its task perfectly, but it also prevents breakage of nuts or threaded nipples of flexible hoses. Keep in mind that these elements are made of a beautiful but very weak silumin alloy, at the slightest excess of allowable forces it gives cracks.
Prepare the tools. You will need a drill with a torch, a set of wrenches or one adjustable wrench, screwdriver, pliers, tape measure, level and a pencil. Most apartment owners have this tool at home, there’s no need to buy anything.
Important. If you fix the water heater to a solid load-bearing wall made of brick or concrete. excellent, their physical indicators of strength allow you to hang such heavy devices. And if for some reason the boiler must be hung on an interior partition wall of foam concrete, then there are certain difficulties. How to solve them, we in this article will tell a little below.
If there is an assistant. lift the heater with him and lean it against the wall in the place of installation, mark the location of dowels with a pencil or marker. Take it away and check the level. Drill holes and install the fasteners in place. Hanging the heater will have to several times, the first time it is difficult to guess the length of the fasteners. Once the device is fixed on the wall, you can let the assistant go, all further work without problems are done alone. Be sure to check the reliability of the attachment. To do this, hold on to the upper part of the body, it must be able to support your weight. No wobbling or large distances from the wall are allowed. Adjusting the distance from the wall is done by tightening the fasteners.
If you do not have an assistant, you need to mark the center of the bar (bracket) fixation. On the wall under the level of the horizontal line for the trimmer and on it put the distance between the technological holes. You will have to lift the water heater alone, and this is quite difficult.
Measure on the wall. Find and mark the center
Remove the plastic plugs from the connections. Pay attention that on the cold water inlet pipe it is blue, and on the hot water pipe it is red.
Start with the cold water connection. Wrap about 6-8 turns of FUM-tape on the threaded part of the outgoing pipe, carefully press it with your fingers around the thread. Wind it clockwise, otherwise during the screwing of the faucet, the tape will slip and the thread will leak. Make sure that the tape does not cover the inlet opening.
Connecting the water heater to the mains
Since the water heater requires a connection to the network of 220V and compulsory grounding, the best option would be to connect to an available outlet for the washing machine. through the plug (of course, provided that this outlet is held on a separate line with the rules).
If the apartment is missing such a socket, it is best to contact electricians for qualified assistance in laying electrical wiring. There are several reasons for this.
First, work with electrical wiring requires certain skills and knowledge, and in the case of non-compliance with certain moments of installation, there is a risk of electric shock or failure of electric devices.
The second, you will be someone to ask for substandard work. Of course, if you have signed a contract with a contractor.
And finally, there will be no problems with the fact what wire to choose, what automatic devices to put.
Perhaps this will encourage you to conduct an audit of electrical wiring in the entire apartment.
And in conclusion, I would like to wish you a pleasant water treatment.
Peculiarities of connecting a floor standing water heater
Since this heater is installed on the floor, all connections to it are not located on the bottom panel, but at the bottom of the side or rear vertical wall. At home, such storage boilers are rarely used, because the smallest of them have a tank volume of 100-150 liters. In addition, they occupy a lot of space and have a high power, which makes serious demands on electrical wiring and safety automation.
Floor standing heaters have water connection similar to wall mounted models. Connection to the mains, due to the relatively high power, must be made only through a separate switchboard.
