Storage water heaters are best suited as a primary or secondary source of hot water. This equipment is very popular, the reason is the intensive increase in prices for utilities. Let's see how the water heater is connected.
Can I install it myself?
Ancestors said that it is necessary to measure seven and cut only once. This wisdom can be applied to the selection of technology for mounting storage heaters. If there is no minimum set of knowledge and skills related to the installation of plumbing equipment, then it is better to entrust the connection of the water heater to experienced professionals. This is more about apartments in cities. If you make even a minor mistake, the consequences can be very unpleasant. It is especially unpleasant to flood the neighbors.
So, self-assembly of these units is associated with serious risks. However, if you follow all the recommendations andadvice, everything will turn out well. Even more - self-assembly and connection allows you to save a lot and gain new skills.
Materials and tools
To connect the water heater with your own hands, you will need a set of tools. This is an ordinary plumbing tool that any home craftsman must have. You need a building level, adjustable wrenches, a marker, pliers, a puncher, screwdrivers and tape measures. You should also purchase PVC pipes and FUM tape, although it is perfectly replaced with linen threads.
Mount the heater on the wall
This is the standard solution used in most apartments. The device is most often installed in kitchens or bathrooms. It must be remembered that the unit is quite heavy and the walls must be load-bearing for its installation. It is also important to choose a location in such a way that the tank is as close as possible to the hot water tap, because hot liquid quickly loses its temperature.
Also, professionals advise to pay attention to the next point. The mounting height depends only on the comfort of use. During operation, you will have to switch various thermal operating modes - it should be convenient to do this.
Installation technology is divided into several stages. Let's consider each in detail. After studying this manual, connecting the Termex water heater and other models will not cause difficulties.
Getting Started
First of all, you need to choose a site. Above weconsidered the nuances of choosing a place. The place where the installation will be performed must meet certain requirements. So, access to the device during the entire period of operation should be unhindered. Pipes, as well as risers, must be in normal, or better, in excellent condition. It happened that instead of installing and connecting the water heater, the master had to deal with the unexpected replacement of parts of the pipeline due to the fact that it was simply impossible to tie into the system - the pipes were very old.
The wall on which the equipment will be mounted must be able to support the weight of the water heater. The load can be from 160 kilograms or more. Also, before installation, it is necessary to check the electrical wiring - it must be in proper condition and withstand heavy loads.
Wiring
Any storage heaters are equipped with powerful heating elements - heating elements. The water heats up fairly quickly. Therefore, there are certain requirements for electrical wiring. The requirements themselves depend on the manufacturer of the heater. In general, the cable section should be 4-6mm2. But it is also necessary to find out the capabilities of the meter, the maximum current for which the meter is designed. If the maximum allowable current is 40 A, then this meter will not withstand the load. It is replaced with a new one. To connect an electric water heater, you will need a switch that can withstand a certain current, as well as cable products 3 x 8 or 3 x 6.
Measurements
When the place is chosen, and problems withwiring solved, you can go directly to the installation work. Using a marker, make a mark on the wall - this will be the lowest point of the water heater. Next, measure the distance between the point and the place where the mounting plate will be attached, which is welded to the top of the unit. Holes are drilled in the marked places.
It is worth paying attention to an important point. There are no holes on the mounting plate. The tank is hung for special fasteners - hook anchors.
If the wall is made of brick or concrete, then conventional hammer drills will be powerless. We need winning products. For a wooden wall, you can use a regular drill. The diameter should be slightly larger than the fastener itself.
Then the dowel is hammered into the hole made under it. Experts recommend hammering the dowel directly with a hammer. Next, a special anchor in the form of a hook is screwed into the hole. A heater will be hung on it. The anchor should be wrapped as far as it will go - this is about 10-12 centimeters. The tank is fixed by clinging the bar to the installed anchors.
This completes the installation work. As you can see, there is nothing complicated in this procedure. However, you still need to connect the device.
Connect water
At this stage, the water heater must be connected to the water supply. The scheme depends on the characteristics of a particular apartment. To connect, you will need hoses, which can be made of plastic or polypropylene. Consider typical optionsheater connections. Having studied them, it will be easy to connect Ariston water heaters and heaters from other manufacturers.
Connection features
The process has two stages. At the first, the heater is connected to the water supply. At the second stage, work is underway to connect the tank to the electric line. And to the water supply, and to electricity, the heater is connected easily. Usually everything is described in detail in the instructions.
Sequence of work
First of all, the scheme for connecting the water heater to the water supply provides for the installation of a cold water filter. It is mounted at the entrance. There is no special need to install a cleaning element on hot water, since the heater will only be connected to the cold water supply system.
If it is planned that the hot liquid will be used only from the boiler, then you can completely block or cut off the hot water supply branch in the apartment. If the heater will be a backup option for preparing hot liquid, then you should first make sure that the installed screen is tight.
The storage water heater connection diagram also provides that the inlet pipe should be located as close as possible to the water inlet to the apartment. No other elements in the wiring and splitters should reduce the pressure. The pipe that connects to the heater must only be used to supply cold water to the tank. It should not be used for anything else.
Specialistsrecommend choosing this PVC pipe. It must also have a reinforcing layer. But it is forbidden to use metal products with these tanks - they do not meet the operating requirements for these units. Brass adapters and taps are used to connect the pipe to the tank. The faucets are very easy to use. They are easy to open and just as easy to close.
The crane is soldered onto the input pipe. When this work is completed, you can proceed to the installation of the adapter. Next, install the check valve. It is needed to completely eliminate overflow from the boiler if the pressure in the system rises. This is the main rule for connecting a water heater to a water supply. Don't forget about the non-return valve.
It should be noted that the faucet also provides a return flow of water if there is increased pressure inside the heater or in the pipes. The adapter nut is installed at the outlet of the device. It is connected to a faucet. This is how the wiring is done and this is how the standard connection diagram for an electric water heater in most apartments and houses looks like.
Installation to metal pipes
You don't even need to use welding equipment to connect. Connections are made using tees - the masters call them "vampires". By design, the tee is an ordinary tightening clamp. On the sides there are nozzles. The ends of the pipes are already threaded.
To install such a tee, first it is mounted in the right place and tightened with the supplied screws. Between the pipe and the metal part of the product putgasket - it is complete. It is very important that the gaps in the tee and in the gasket are exactly in the right places.
Next, using a drill, a hole is drilled in the pipe through the clearance in the pipe and gasket. Next, either a thread is screwed onto the hole or a hose is attached. Through the last water will go to the heater. Such a scheme for connecting a storage water heater is quite applicable in city apartments.
A very important point is the strict sealing of each connection. FUM tape, flax thread or other sealing materials are used to seal threaded connections.
Connect to the mains
Here, too, there are no particular difficulties. However, there are still points that you need to know and consider. The most basic nuance is power. It must strictly correspond to the type of cable that is used in the process of connecting the storage water heater. For greater reliability, it is recommended to purchase copper wires. Their cross section can vary from 2.2 to 2.5 mm2.
So that the heater does not cause any problems to its owner in the future, works properly and reliably, you should pull a separate line for it from the electric meter. In this case, the tank will be completely safe for further operation.
When installing the device in city apartments, do not forget about the need for grounding. It would seem that in city apartments with the connection of a storage heater there can be no problems with grounding, but sometimes they happen.– due to insufficient grounding, the device shocks the user. If the apartment has grounding, it is better to connect it.
Instantaneous water heaters
This is another kind of water heater. Unlike storage devices, there is no tank in which water accumulates. According to the principle of operation, the heater resembles a gas column. But in this case, the coil through which the code passes is heated by electricity. Let's see how an instantaneous water heater is connected.
Checking the mains
The first step is to check the electrical wiring and determine if it can withstand significant loads from the flow heater. The modern market offers products with a power of up to 10 kW. Storage heaters are easily plugged into a regular electrical outlet, but flow heaters have a higher power. When enabled, certain problems may occur. Sometimes, after switching on, the wiring burns out and it is necessary to change it all.
They also change the wiring if it is simply old or there is no grounding in it. This is often found in country houses. If repairs have recently been made and the electric line has changed, then for a reliable connection of the flow heater, it is enough to stretch a separate new cable. It should be pulled straight from the junction box.
Fastening
At this stage, you need to fix the body of the flow heater to the wall. To do this, you need to choose any suitable place anddrill holes. Most often, special mounting brackets or hinges are included with the device. One important condition - you need to fasten so that all planes are perfect. Even if there is a slight skew, the heating element of the flow heater may fail. The element will not be completely covered with water, which means it will not cool enough. This will cause the heater to burn out.
Heaters of this kind are installed in the kitchen or in the bathrooms. Due to the small overall dimensions, the device is perfectly installed under sinks, in the bath - under the sinks. This will allow you to use hot water and save space.
Connecting electricity
This step is to connect to the electrical network. The water heater connection diagram is quite simple. Remove the protective screen and lead three wires into the appropriate block. There is a special color marking on the block and in the instructions - it is extremely difficult to confuse the wires. It is imperative to organize grounding - it is forbidden to operate the device without it.
Connect water
Everything is very simple here - there are two exits on the case. The first is needed to supply cold water, the second - to exit the device is already hot water. The scheme for connecting an electric heater to the system is the connection of the corresponding hoses. If the heater is needed temporarily, then it is connected in place of the shower hose.
If you need it all the time, then you can directlyjoin the plumbing. To do this, use a tee and a stopcock.
Conclusion
Thus, a storage and instantaneous water heater is connected. In fact, there is nothing complicated here. Everything can be done by hand. No special tools are required for installation and connection.
