What is a household heater? - Its types and principle of action

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

Accumulative water heater

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

Instantaneous water heater

Water in this type of device is heated when it is supplied through a special flask - there is an electric heating element in its design. This device is installed on a tap with water. Thus, the water is heated to 30 degrees. A spiral or a heating element can act as a heating element.

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

Significant disadvantages of the flow-through type of a device for heating water is its high energy consumption. Therefore, the installation of this type of device is not always suitable for old buildings. Before installation, be sure to check the condition of the wiring.

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

To perform its functions, the device also needs a high water pressure in the system. If the pressure is low, then there is a chance that the device will burn out.

Important! Due to the requirements regarding water pressure, such a water heater cannot be used on the upper floors of multi-storey buildings.

Installation of a storage water heater

After the device is mounted on the wall, you can begin to connect it to the water supply and power system.

Stage 1. Connection to the water supply:

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 In the case where the connection points are withdrawn, you only need to connect them to the input and output of the device using flexible hoses or pipes.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

Important! In the heating device, the hot water inlet is marked in red and the cold one in blue. A special valve is installed on the latter, which relieves excess pressure.

2. For convenient maintenance, an additional tee is recommended to be installed and connected in front of the stopcock. It will allow to lower water from the reservoir in the future.
3. Ensure tightness of all compounds by winding FUM tape or thread with paste on them.

Stage 2. Power supply

The way the device is connected to power is determined, by and large, by the preferences of the device owner.

The terminals are labeled as follows:

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

When installing an electric instantaneous water heater with your own hands, follow these recommendations:

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

Having done all these manipulations, the storage device is considered ready for use.

DIY electric instantaneous water heater installation

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 a flow-type electric water heater will be your best option.

Important! The compact size and light weight make it possible to install such a heating device in a place with limited space, for example, under a kitchen sink.

Water is heated by the device quickly enough, therefore, special requirements are put forward to the electricity meter and wiring:

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

Do-it-yourself installation of a flowing water heater can be carried out in two ways: stationary and temporary.

Temporary connection

For such a 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 instantaneous water heater requires the supply of cold water. To do this, a tee cuts into the cold water supply pipe, a shut-off valve is mounted, a flexible hose is connected to the input of the water heater.
2. After such manipulations, open the cold water valve and the outlet valve for heated water.
3. Plug in the appliance.
4. After half a minute, hot water will flow.

Fixed connection

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

Procedure:

1. Turn off the cold water supply to the apartment.
2. Install the tap adapter in the intended location using the FUM tape.
3. Install the electric drive according to the wiring instructions.

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

4. Screw the water heater to the wall in a previously prepared place.
5. Attach a valve to the inlet pipe of the device, and a flexible hose or ceramic-metal pipe to it.

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

6. Install a faucet or shower faucet that comes with the heater.
7. Turn on low water pressure and power to the unit. After 10-15 seconds, warm or hot water will pour from the tap.

Important! Heat and water pressure are regulated by a valve.

8. If the water heater is far from the sink, the mixer should be connected using a flexible hose, and fixed on an additional bracket near the sink in a place where the additional gantry crane does not cause inconvenience.

How to install a gas instantaneous water heater?

An excellent alternative to an electric appliance for heating water is a gas heater, which works according to the flow principle. Such a device can be installed in your apartment only if you already have a gas column. If there is no column, then self-assembly of the heating device is against the law.

Important! The installation of a gas water heater must be agreed with the gas services.

The water heater is installed either in the kitchen or in the bathroom.

Important! A hood must be installed in the room. Do not install the heater over a gas stove.

The wall on which the gas column is planned to be installed should be fire resistant, and the water pressure should be at least 0.1 amt.

Important! Before installing a gas water heater with your own hands, you must take care of the hood. It must be assembled from non-combustible material.

Procedure:

1. Using screws, screw the column to the wall. Use a flexible corrugation to connect the appliance to the chimney.

Important! It is advisable that the gas water heater be placed at such a height that children cannot reach it.

2. Insert the tee into the gas pipe. To do this, use gas welding if your parts do not have a threaded connection.
3. Screw the tap to the tee.
4. A tee crashes into a water pipe. It is mounted on the same principle as in the case of connecting to a gas pipe.
5. Mount the Mayevsky crane, which will regulate the water pressure.
6. Install salt and magnesium filters near the column.

Important! Installing filters will significantly increase the life of a gas instantaneous water heater. They are best installed both on the cold water pipeline and on the hot water outlet.

After such actions, it is believed that a do-it-yourself gas water heater is safely installed.
