How to install water heater with your hands

How to install water heater

1. Prepare tools and materials

• water heater;
• Hammer or percussion drill;
• concrete drill bit;
• level;
• hammer;
• wrench and pliers;
• screwdriver;
• roulette;
• pencil;
• anchor bolts or hooks;
• FUM tape;
• safety valve;
• 2 flexible hoses;
• 3 ½ inch tee diameter;
• 3 DN15 crane;
• PVA cable 3 × 2,5;
• Emergency circuit breakers 16 A.

2. Choose a location

Savings Water heater are better placed closer to the risers of hot and cold water to reduce the length of the feed pipes and to ensure good pressure. Boilers of small volume can be mounted on any wall for models with capacity of over 80 liters only suitable carriers walls of brick and concrete: on their own water heaters weigh a bit, but with the load of water is obtained considerable.

With this in mind, not so many suitable places in the apartment. As a rule, the choice boils down to four options:

• over the toilet in the bathroom - next to the risers, it does not take place in the bathroom, you can hide behind falshstenu in a box with communications;
• of Bath - bathroom and small bathrooms, almost does not interfere with the length of 160 cm from the bath;
  instagram viewer
• under the sink in the kitchen - only for small models to 10-15 liters;
• the ceiling in the hallway or corridor - is mostly used with horizontal boiler and to save space, but requires additional piping.

3. Secure water heater

Installation is carried out by means of hooks that are attached to the wall, they put on the drive. Either a special strap, it is mounted to a surface by anchor bolts, and the boiler is already fixed to it.

By measuring the size of the tank, think the location on the wall so that the corners and edges of the niche there is a gap of 2-3 cm, and the cover can be removed for repair and maintenance. The ceiling is necessary to make a gap of at least 5-7 cm in order to hang on the hooks of the tank or the bar.

Using the template, mark and drill holes for hooks or anchor bolts. If there is a lining tiles, First go through its special drill for ceramics. Then the main part of drill hammer or impact wall drill with drill concrete.

Install the dowels into the holes and screw in the hooks. Either insert the anchor bolts through the mounting plate holes in the wall and screw them key.

Hang the boiler on the fasteners. The spirit level, check if there are any deviations and horizontally vertically. Otherwise, the risk of air pockets and the failure of the heating element.

Important! Water heaters with a vertical arrangement in any case must not be mounted horizontally to save space.

4. Connect to the water supply

Hydraulic assembly is carried out as follows. Compounds themselves can be made as via flexibles and with plastic or polypropylene tubes. The first option is easier, therefore, consider it.

Screw on the cold water pipe boiler, designated blue tee ½ inch diameter. To connect the lower tap valve (arrow towards the cylinder), and to the side - the ball valve. He will come in handy when you want to drain the water. All threaded connections tighten FUM-tape.

On input of cold water faucet riser tee set and connect the ball valve previously podmotav in FUM-thread tape. Connect a new tap with safety valve for a boiler with a flexible liner. Place the rubber gasket under the union nut and tighten the key.

Screw hot water pipe boiler ball valve and the valve on the inlet of hot water riser - tee. Seal all thread FUM-tape and connect a new valve with T-piece using a flexible liner with established under gaskets nuts. Tighten first by hand and then key.

If you can not install tees riser hot and cold water, then connect the boiler to the nearest faucet. In this case the tee nipples are installed on the hot and cold water faucet, and then connected to a tee flexible liner mixer and heater.

At the tip of the safety valve, wear hose, and bring down the drain. Through it sometimes will drip water during heating and expansion - this is normal. If the boiler is over the bath, the tube can not print: just a drop fall into the drain.

5. Connect to power

If the heater is already ready-made cable with a plug, it is enough just to insert a grounded socket. Extension cords can not be used at the same time as the load on the network is high enough: all additional contacts will be very hot, which could result in a fire.

In other cases, the cable will have to be connected independently. If he does not go in the complete set - use trohzhilny wire cross sections of 1.5, and preferably 2.5 mm². It is desirable to connect directly from the switchboard.

Before starting work, unplug the electricity supply by turning off the switch in the hallway. Route cable 3 × 2,5 mm² from apartment and connect the panel to the boiler through the differential circuit breaker 16 A. Then connect the wires to the terminal block on the water heater: phase - concluded L, neutral - to the N, and the ground - to pin PE or on the body.

6. Take a test run

Before turning on the boiler it is necessary to fill the tank with water. For this shut off valve on the hot water riser pipe, and then open the valves at the inlet and outlet of the heater. Turn on the hot water at the next mixer and wait a few minutes until the tap will not go flat jet of air and without interruptions.

Close the mixer. Carefully inspect all connections to the boiler and check for leaks. Turn on the heater at the outlet or via Emergency circuit breakers and start heating by a button or the temperature regulator.

How to install free-flow water heater flow

1. Prepare tools and materials

• water heater;
• spanners;
• Hammer or percussion drill;
• drill on concrete or wood;
• dowels or screws.

2. Choose a location

Unconfined protochniki usually able to provide only one point of water pumping, so the question of choice is not worth a place. The device is installed in place of the mixer on the washstand in the bathroom or in the kitchen, as well as next to the tap in the shower.

3. Secure water heater

The device is in the form factor of the crane mount easier. For this purpose, turn off the water to the mixer and remove the flexible liner. Unscrew the fixing bracket and remove the crane from the sink.

Assemble the heater according to the instructions, attach the spout, screw the inlet nozzle and insert into the hole in the sink. Screw the nut and tighten it to secure the protochnik.

Wall-mounted models have to be mounted on the dowels or screws, depending on the type of wall. Using a template, or by measuring the distance between the brackets, make the layout and drill holes. Secure water heater dowels or screws.

4. Connect to the water supply

Here, too, everything is simple. Connection is reduced to joining the flexible liner, which you have removed from the mixer to the water heater fitting. Install rubber seal under the cap nut and tighten it by hand first, then with little effort using the key.

Wall protochnik can be powered from the same flexible liner from the shower or faucet. To do this, remove the hose from the watering can, and connect to the input of the freed end of the heater.

The important point! After the water heater should be no shut-off valves. Water is covered exclusively by protochnikom or crane, to which it is connected. Otherwise, due to lack of duct heater may overheat and fail.

5. Connect to power

Compact non-pressure models usually have a ready cable with a plug, so the connection is to ensure that the need to insert the plug into socket grounding. As relates to a heater power devices, to connect it through tees and extenders prohibited. Due to the high current contacts in them can overheat, melt and cause a fire.

6. Take a test run

Shut off valve on the hot water riser. Open the mixer and let the water through the device. Wait a few seconds until it goes flat jet. Put the appliance in heating mode by turning the lever or pressing. Check that the water is heated.

How to install the flow pressure water heater

1. Prepare tools and materials

• water heater;
• Hammer or percussion drill;
• concrete drill bit;
• ceramic drill bit;
• level;
• hammer;
• spanners;
• screwdriver;
• roulette;
• pencil;
• screws or dowels;
• FUM tape;
• 2 flexible hoses;
• 2 tees ½ inch diameter;
• 2 DN15 crane;
• PVA cable 3 × 4;
• Emergency circuit breakers 25 A.

2. Choose a location

Unlike compact pressureless models pressure protochniki able to provide hot water several points. They can be installed in any location, based on the possibility to connect to the water supply, but it is better closer to the device, where the hot water will be used more often.

In the conditions of the apartment for that is the space under the sink in an alcove with communications in the bathroom or just on one of the walls next to the pipes of cold and hot water. The main thing - to eliminate splashes on the body and provide free access to it in the case of repairs.

3. Secure water heater

Using the template from the kit, mark and drill a hole punch for mounting the cylinder. Insert the dowels and fasten securely protochnik on the wall with screws. Check the level of the appliance is level horizontally and vertically.

In some models, you will first need to remove the front panel to set the water heater on the mounting plate. After connecting to the water supply and the electricity it needs to be put back into place.

4. Connect to the water supply

As the boiler, the discharge flow-through water heater must be applied to the cold water input directly from the riser or any place the flat wiring, and connected to the output of a flexible hose for connection to a hot water tap line for the riser DHW.

Replace fittings protochnika ball valves to turn off the unit if necessary. Seal thread via FCM tapes. Pipes of hot and cold water deliver tees and connect their outputs with respective valves on flexible cylinder liner.

5. Connect to power

First, make sure that the power allocated to the apartment sufficient for the selected heater. It should be enough with a stock, or by heating the water will be disconnected machines.

Due to the large capacity pressure protochniki not normally connected to the socket, and immediately to the electrical through Emergency circuit breakers respective nominal current. This uses trohzhilny cable section 4 or 6 mm².

6. Take a test run

Close the valve on the hot water riser open and the stop valves on the cylinder. Turn on the hot water at the next mixer and wait for a few seconds until it will flow stable flow without jerks.

Apply power to the heater circuit breaker and activate heating. Open the hot water and make sure that everything works.
