Install the heater with your hands seems like a daunting task? I know how to do it, I can help to understand and then explain in detail how to install the water heater on their own and you need to do.
With the water boiler in your home will always be hot water.
types of heaters
In private houses and city apartments set 3 kinds of water heaters:
- gas heaters - column;
- Electric heaters accumulative type - boilers, the Titans;
- Electric instantaneous devices.
|Illustration||Brief description of household water heaters|
Following a flow method, where water passing through the radiator heated by the gas burner.
Installation of gas columns with their own hands is strictly prohibited. Installation may only be carried out specialists. Plus you need to obtain official permission for the installation of the column.
Represent the reservoir volume from 20 to 150 liters in which an electric heater. After filling the heater heats the water tank gradually.
The installation of the boiler or used to be called titanium, permissions are required.
On the device are similar to savings. Only the working capacity in them is much smaller, and the heating elements is several times more powerful. As a result, the flow of water is heated for 30-60 seconds.
Installing the flow-through heater does not require any permits.
Subtleties of self-installation storage boilers
Installing the storage-type water heaters is advantageous economically. The average power consumption of heating element in them is 2-3 kW, while the flow-through unit consumes a minimum of 6 kW.
If you have a home water meters are installed, you do know your needs and will be able to more accurately select the desired amount of water heater.
Tools and materials
- Drill or punch with the best set of drills;
- Measuring tape, pencil, level;
- Adjustable wrench and carob desirable set of keys;
- Die half an inch ratchet;
- Screwdriver Set;
This set of tools is required if all the household work is done on their own.
If the wiring plan on doing polypropylene tubes, then they need a soldering iron. Buy it for a one-time work does not make sense, it is easier to rent.
Soldering for polypropylene pipes having at desirable, but not required.
- Anchor bolts or hooks with plastic dowels. On the container 50 l take-section of 10 mm, a volume of 100-150 liters bins are suspended on hooks or anchor section of 12-14 mm. The working length of the anchor 100 mm (depth at which it enters the wall);
Inexpensive and reliable hanging hook with plastic plugs that can withstand the boiler.
- Sealing fum-tape or tow a sealing paste;
- brass tee half an inch - 1 pc .;
- Ball semi-turning valves ½ inch - 3 pcs .;
- Adapter "American" - 2 pcs.;
Without the "American" adapter, you may not be able to collect the wiring for a storage heater.
- Reverse the blast valve - 1 PC. (Supplied with boiler);
- Machine 16 amp double pole - 1pc .;
- Copper three-core wire of at least 2.5 mm2. Better to take with solid conductors, stranded because you need to be propaivat or compressing.
On the majority of heaters are mounted ball valves are one-half inch.
Installing the water heater takes place in 3 stages:
- Marking and fixing the boiler to the wall;
- Cold water connection and assembly output to a hot water tap;
- Connecting the device to the mains.
Weight boiler is large and it must be suspended on main wall thickness of at least 20 cm. On partition in half-brick mounted even dangerous capacity of 20 liters, no mention of 100 and 150 liters.
Scheme installation mounts for the water heater.
Capacity need to hang as close as possible to the mixer, so you will have less work with the laying of pipes and water on the way to the tap will not cool down. In the model homes is better to mount the tank on the toilet. In a small bathroom or over the sink in the kitchen boiler will stop.
Installation of the heater starts to measure distance from the fastenings, which is suspended to the top of tank capacity.
The markup for the suspension strap.
If you plan to hang the container on a special harness bar, the mark and hang the boiler can be close to the ceiling.
To avoid scratching the tank top, leave a gap of 10-20 mm.
Marking for anchors or hooks.
If you hang boiler anchors or hooks, the distance from the ceiling to the suspension points must be equal to the distance from the anchorage capacity to the tank dome, plus 50-70 mm.
Otherwise you will not be able to put on a container on the hook will prevent the ceiling.
Installation of hangers.
Take perforator drill insert into it and drilled holes of Markings applied depth of not less than 100 mm.
If the boiler is suspended on the anchor, then select the drill diameter of the anchor.
When the suspension in the hooks with plastic auger anchors selected by 1-2 mm thicker hook to the plastic anchor into the hole tightly.
Suspension for 2 and 4 points.
If the container 1 is provided hanging strap, then you are screwed into the wall 2 of the anchor and suspended.
For a tank with two mounting straps you will need to measure the distance between the slats, transfer marks on the wall and below the screw has 2 anchor.
Empty the tank on the anchors or hooks can hang any adult male.
Installing the storage heater on the mounting plate may require the participation of 2 persons.
Once you put in the tank bolts, one person will be slightly fix the tank on the wall, and the other to tighten the nuts.
If the bearing capacity of the wall is weak, then every point of fixation is not mounted on the 1 and 2 on the anchor bolt, with the use of a special outboard corner.
Heaters large capacity can be mounted on a reinforced suspension.
Mounting of pipework
With pipes for hot and cold water in the boiler is difficult to make a mistake, they are designated plastic cuffs. Under hot water cuffs will be red under cool, blue.
Control group: the tee, the drain valve, check valve and an explosive valve overlapping water, we install to introductory pipe for cold water, it is always on the right.
Such a scheme is the fact that water is drained from the container only through the cold pipe. Inside the container the nozzle is substantially at the level of the bottom, and a tube for intake of hot water rises almost to the vault, respectively drain therethrough impossible.
|Illustration||Connecting to the water heater and the hot water tap.|
Fitting tee ½ inch.
Brass tee needed to install the crane under the emergency discharge of water from the tank.
First try it just to wind, 90% of it comes by 1-1.5 turns. As a general rule, and without short thread filled with paint.
What we need at least 3.5 turns, or tee it will be broken eventually.
You take a half-inch plate, insert it into the ratchet and drive off the threads on both connections.
It takes you a maximum of 5 minutes, but the tee, "sit" reliably.
Sealing is wound on the thread sealing compounds.
Simply wind the coils 3-4 fum-tape and compress it with your fingers.
Professionals prefer to wind hemp and sealing paste to lubricate it. Both options are correct.
The drain valve is needed for emergency drain water from the boiler.
Without the tee and drain cock can do, but if you want to clean or repair the boiler, the empty tank will be problematic.
Setting the reset valve.
Reverse resetting (explosive) valve is needed for normalization of pressure in the tank. It has an arrow indicating the direction of the water flow.
Plus, if the water is shut off in the building, the valve will not allow water to escape from the tank back to an empty tube.
The valve must be precisely explosive, i.e. with the possibility of pressure relief. If you put a simple non-return valve, then you squeeze the gasket and the tank will start to flow.
Installing the stopcock.
Shut-off valve is needed in order to block the flow of water into the boiler.
We use semi-turning ball valve and connect it through the "American" type adapter.
Installing the adapter.
Solder adapter is already part of the pipeline, it will be soldered polypropylene tube.
Often conclusion that the stationary conduit is located directly beside the boiler.
In this case, there is no point to solder an adapter polypropylene, it's easier to install a flexible hose.
Put hot tap water.
To be able to close the hot water is put on the output is exactly the same valve as in cold.
Mounted crane through the "American woman" and the bottom solder screwed clutch for polypropylene wiring.
When soldered pipework, it is advisable to check the tightness of all connections, this system needs to be filled with water. everything is simple here:
- hot water tap open to the boiler and to the mixer in the bathroom or in the kitchen (depending on where you are summed water);
- Then open the cold water into the tank;
- For a time, from the hot tap will poison the air. When the tank is full, it can go rust and debris. After the clean water will overlap all the taps and scans the system for leaks.
Schematic diagram of the connection of the boiler pipework.
heaters are often put in apartments with hot water as insurance if you disable the hot water. In this case, before turning on the boiler, you will be sure to block the opening valve hotline, or the pressure in the pipes squeeze seals in the tank.
Capacity will start to flow if the seals squeeze or they will be ruined.
Boiler connection to the network
Installation of the water heater is completed by wiring it to the network. When you remove the protective cover, there are 3 connection points - phase and ground zero. They can distinguish color or letters on the terminal box:
- L - phase (generally colored in brown);
- N - neutral conductor (blue or blue);
- Grounding is marked by a triangle of several parallel strips, and often colored yellow, although sometimes there are other colors.
connecting point lived in the cable can be determined by color.
Heaters for household machine enough to 16 A. And remember, this is not the case that the more the better, when a short circuit or the occurrence of a machine should switch off the appliance. If you take the machine, for example, 25 A or more, then you and the house burns down and the machine did not knock out.
Electric desirably connected through pole machine 16 A.
Automatic is better to put a two-pole, and immediately on the phase and zero, if you purchased a single-pole, then put it on the stage. After entering the machine or in the house, it is desirable to set the line RCD (residual current device). This device will duplicate machine in case of emergency.
Passing through the machine and the RCD, the phase and zero are connected to the terminals on the boiler. Grounding bypassing machine directly connected to a special terminal on the tank.
Electrical wiring diagram of the boiler.
Grounding must be reliable and proven. Some bolted wire to the battery or metallic water pipe, and believe that this is sufficient. So you do not need to do.
In high-rise buildings have quality grounding at the distribution board, and if you live in a private home, the hammer land 3 in two-meter metal pin at a distance of 1 m from each other, connect them in series and receive ground.
According to this scheme you can arrange grounding in a private house with his own hands.
After switching on the instrument panel will light network. Tank capacity is 100 liters is heated for about 2 hours heating rate can be controlled by temperature sensor which is installed on the tank or on the dashboard.
The temperature in the reservoir can be monitored by the sensor on a casing.
- Prohibited network does not include a water-filled boiler;
- Prohibited drained without disconnecting from the network apparatus;
- Prohibited without explosive return valve storage heater connected to the water mains with a pressure of 6 atmospheres;
- Prohibited use ungrounded or poorly grounded electric storage heater;
- Broken or burnt parts should be changed to similar, the differences in performance can lead to an accident;
- If you use ordinary tap water (without further purification), the interior of the tank from scale and debris should be cleaned about 1 once a year.
Descaling and debris - a mandatory procedure for any storage water heater.
There is another important point: in Moscow and St. Petersburg, the price of the installation of the water heater is around 3000 rubles, the same is the dismantling of the old unit. Self installing water heater will take you about 2 hours and the cost is free.
Installation of the instantaneous water heater
In technical terms, the instantaneous water heater installation is easier than installing water heater. It will not need to install a protecting group (tee, valve and dropping explosive return valve).
Instantaneous water heaters can come in various models.
The stationary models put a ball valve at the input and the second output and the device is started. As for the portable models, then I met devices, which is set on the input hose, you it is necessary to pull the hose to the faucet spout cold water, connect the heater to the network and can be taken shower.
If a fixed connection only ball valves are installed on the flow heater.
Electrical connection is the same as in the storage apparatus. But beware, not every entry can withstand this load. Copper wiring must have a section of 2.5 mm2, 3.5 mm2 aluminum.
Dear Modern heaters are equipped with a reliable automatic and able to work autonomously. The available models protect weak and the water in the container does not boil or PETN are not fused, such a flow machine is turned on with a certain sequence:
- Open the valve for supplying cold water;
- Open the hot water tap and wait until it goes out of the cold water;
- Now it is possible to include a network switch, and within a minute you have to get hot water.
Turn off the water-heater is necessary in reverse order.
The dimensions of the flow-through heater are small, which allows to install it on the wall of a bathroom or kitchen.
Installation of the heater described scheme I tested in practice. The photo and video in this article the main stages of installation are shown graphically. If there are any unclear points, write questions in the comments, I'll try to help you.
Storage-type heaters can be connected via flexible hoses.
