What is a household heater?- Its types and operating principle

A domestic water heater provides an apartment or a separate house with hot water. They differ according to the principle of work and the source of power. In the first case, they are flowing and accumulative, and in the second - electric and gas.

DHW cylinder

This device for heating water is the most common. This is explained by the lack of special requirements for electrical wiring and attractive price. It is a reservoir in which water is heated.

Flowing water heater

The water in this kind of appliance is heated when delivered through a special flask - in its design there is an electric heating element. This device is installed on the faucet with water. Thus, the water is heated to 30 degrees. As a heating element, a spiral or heating element can act.

Important! In the case of hard water, it is better to choose a device with a spiral heating element.

Essential disadvantages of the flow-through type of the device for water heating is a large power consumption. Therefore, it is not always suitable for old buildings to install this type of device. Before installation, always check the condition of the wiring.

Important! Devices with a heating element in the form of TETs consume 10-20% less electrical energy than devices with a spiral.

Also, the device for the performance of its functions requires a high water pressure in the system. If the pressure is low, then there is a possibility that the device will burn.

Important! In connection with the requirements for water pressure, such a water heater can not be used on the upper floors of multi-storey buildings.

Installing a flow-through water heater with your own hands. General advice

First of all, it is necessary to determine the installation site and the conditions for the further operation of the device:

• The device must be freely accessible during the entire service life.
• Choose a wall for fixing, taking into account the requirement: the wall must withstand twice the load greater than the weight of the heating device.
• Check the condition of the wiring if you plan to install an electric water heater. It must withstand the power of the heating element. If necessary, the wiring should be replaced.
• Check the condition of pipes and risers in the apartment. In some cases, it is necessary to replace the pipes for installing a device for heating water.
• Prepare all the necessary tools in advance.

Important! All work must be carried out in accordance with the general safety rules. It should also take into account the manufacturer's requirements for the installation and operation of a particular device.

Work equipment:

• Rotary hammer with required nozzle;
• Roulette;
• Wrench and adjustable wrench;
• Screwdrivers of two types;
• Pliers;
• Combination pliers;
• Pasta or ribbon of a fum;
• Fittings;
• Flax thread;
• Metal-plastic pipe, the length of which depends on the conditions and the place of connection;
• Two connecting hoses;
• Stopcocks;
• Tees.

Important! Shut-off valves and tees in the case of connecting an electric flow-through water heater with their own hands will require 2 pieces, and for installation of a storage device - 3 pieces each.

Water heater fixing:

1. Mark the place for fixing the appliance on the selected wall.
2. Measure with roulette the distance between the holes of the anchors of the device. Put a hole on the wall of the hole.

Important! When making measurements and markings on the wall, be aware that there must be some distance between the device and the ceiling.

1. Drill holes with a perforator. There will be two or four - depending on the model of the device.
2. Insert the dowels and tighten or hammer the hooks.

Installation of the storage heater

After the device has been fixed to the wall, it is possible to start its connection to the water supply and power supply system.

Step 1. Water connection:

1. In the case where the connection points are withdrawn, you only need to connect them to the input and output of the device via flexible hoses or pipes. The tightness of the connection when using flexible hoses is provided with a rubber seal.

Important! In the heating device, the hot water inlet is indicated in red and the cold one in blue. At the latter install a special valve, which relieves the excess pressure.

1. For convenient maintenance before the shut-off valve it is recommended to install and connect an additional tee. It will allow to drain water from the reservoir.
2. Tightness of all joints should be ensured by winding a PCM tape or thread with paste on them.

Step 2. Power supply connection

The method of connecting the device to the power supply is determined, by and large, by the preferences of the owner of the device.

The terminals are marked on the terminals as follows:

• A - phase. Brown wire.
• N is zero. The blue wire.
• Grounding. Yellow wire or any other color in a three-core cable.

When installing an electric flow-through water heater with your own hands, follow these recommendations:

1. After connecting, apply power. The device should light up.
2. Adjust the temperature according to the instructions of the water heater.

After performing all these manipulations, the storage device is considered ready for use.

Installing an electric flow-through water heater with your own hands

If you have a small family, you live in an apartment on the lower floors or there is no place to install a bulky storage device for heating water, then an electric water heater of the flow type will be your best option.

Important! Compact dimensions and light weight allow to install such a heating device in a place with a limited space, for example, under the kitchen sink.

The water is heated up by the device quickly enough, therefore, special requirements are put to the electricity meter and wiring:

• The cable must be 4 to 6 square millimeters;
• Counter from 40 A;
• Circuit-breaker from 32 to 40 A.

The installation of a flow-through water heater can be done by one's own hands in two ways: stationary and temporary.

Temporary connection

For this connection you will need a shower hose. When the centralized hot water supply resumes, the hose is simply closed and not used.

Procedure:

1. This type of installation of an electric flow-through water heater requires the supply of cold water. To do this, a tee cuts into the cold water supply pipe, a stop valve is installed, and a flexible hose is connected to the water heater input.
2. After such manipulations, open the cold water valve and the outlet valve for the heated water.
3. Connect the appliance to the mains.
4. After half a minute, hot water will come in.

Fixed connection

This connection provides the intake and supply of hot water simultaneously with the operation of centralized hot water supply.

Procedure:

1. Shut off the cold water supply to the apartment.
2. Install the branch adapter in the intended location using a PCM tape.
3. Activate the electric actuator according to the wiring instructions.

Important! The consumed heating power should not exceed the possibilities of electrical wiring, otherwise - the inclusion of a water heater in the network can lead to knocking out plugs or a fire.

1. Screw the water heater to the wall in a pre-prepared place.
2. Connect the valve to the inlet pipe of the device, and to it - a flexible hose or a metal-ceramic tube.

Important! The hose or pipe is connected to a specially prepared adapter.

1. Install the faucet or shower mixer that comes with the heater.
2. Turn on the weak water pressure and power supply of the device. After 10-15 seconds, hot or hot water will flow from the tap.

Important! The heat and pressure of water is regulated by the valve.

1. If the water heater is far from the washbasin, the mixer should be connected using a flexible hose and secured to the additional bracket near the sink in a place where the additional gander-gander does not cause any inconvenience.

2. Screw the faucet to the tee.
3. The tee cuts into the water pipe. It is fixed by the same principle, as in the case of connection to a gas pipe.
4. Mount the Maevsky cock, which will adjust the water pressure.
5. Install salt and magnesium filters near the column.

Important! The installation of filters will greatly increase the service life of the gas flow-through water heater. They are best mounted on a pipeline with cold water and at the outlet of hot water.

After such actions it is considered that the flow-through gas water heater has been safely installed by its own hands.
