- Operating Rules:
If there is no hot water in the house or centralized hot water supply is prevented, you can use a domestic hot water heater. The installation of a storage electric water heater makes it possible to use it everywhere. Many different models are produced, with different shapes, capacity and capacity.
to contents ↑Water heater types
There are a number of water heaters that are used in country houses. They can use gas, firewood or other materials as fuel.
Important! Old apartment buildings are most often equipped with gas water heaters. But, on the other hand, they do not turn off hot water, as there is no connection to hot water supply.
We will talk about more universal water heaters - electric. They are suitable for almost any apartment or house.
The heating method divides all such appliances into two types. They happen to be:
- Cumulative;
- Flowing.
Differences:
- Dimensions that are much smaller in the flow unit;
- The price that the savings is often higher;
- Principle of operation.
How is the storage electric heater arranged?
Despite the fact that the device of a flowing electric water heater is quite simple, this device is very reliable and economical.
Important! The saving is that the water is heated gradually, which does not require high power. It is quite enough ordinary voltage 220 V.
Basic equipment
In general, the device of the storage electric water heater consists of:
- Enclosures;
- Baka;
- Thermal insulation layer;
- TEN;
- Magnesium anode;
- Thermostat;
- Control unit;
- Security Systems;
- Indicator;
- Electrical cable.
Function of the
For proper operation of the water heater, you should familiarize yourself with the principle of its operation:
- Inside the heater housing there is a container, which is usually used for the production of corrosion-resistant steel.
- On the surface of the outer shell is usually applied high-quality enamel.
- For the insulation between the tank and the body, polyurethane foam is used.
- For the treatment of the inner surface of the container, a glass pane is used. Such material does not exfoliate, therefore the water remains pure, which is of no small importance.
- The location of the tank can be both horizontal and vertical. This is important, if we take into account the limited area of the room for the location of the device.
- The heater, located inside the tank, heats the water.
Important! It should be understood that tanks with different volumes are heated for different periods of time.
Device of protection system
In addition to TEN, a magnesium anode is located inside the tank. It is of great importance for the life of the entire device, since it does not form rust. The entire surface of the tank is covered with an anti-corrosion coating, but corrosion is susceptible to existing welds.
Important! Requires periodic replacement of the anode. Depending on the manufacturer, it will serve a different period. Manufacturers do not disclose the secrets of production.
In addition, the storage water heater is also equipped with an integrated protection system, which includes a non-return valve, reducer and safety valve. Thanks to all of them, the boiler does not freeze and does not overheat, which allows it to work longer:
- With the help of a pressure reducing valve, the pressure in the unit itself is controlled, it is reduced to the required level.
- The purpose of the non-return valve is to pass water only in one direction, preventing its spontaneous discharge when the feed stops unexpectedly.
- The safety valve opens when the water is heated and a significant pressure increase occurs. In this case, excess liquid is drained into the sewer.
Important nuances
Some valve configurations do not, therefore, a separate purchase of a safety group is required. The materials from which the valve is made are of great importance. They must be of high quality. Installing this part is not so simple, so it's better to trust it to a professional.
After the safety system is installed, before starting the heater and starting its operation, the equipment is started in the test mode and each valve is checked.
Important! In order for the equipment to work safely, a protective shutdown device must be installed on the electrical cable, presented as a small unit with buttons and indicator lamps.
to the contents ↑Operating instructions:
- When using a storage water heater, you can select the operating mode that will be most convenient. With periodic use of hot water it makes sense to periodically turn off the device. If the water is used continuously, there is no sense in permanently switching on and off the boiler.
Important! If the capacity is long without water, there is more chance that it will be covered with rust inside.
- The room temperature should not be below five degrees. That is, the water heater can not be left for the winter in the country.
- When installing the device, it is absolutely essential to ground. In this way you can protect yourself from an accident.
- The device can only be connected to a network with a water tank filled with water. Otherwise - you can immediately lose it.
- To prevent fungi and bacteria from multiplying in the liquid, the temperature is recommended to be set at least 55 degrees.
As you can see, there is nothing particularly complicated in the device or operation of a water heater. It is important only to comply with the main points that we described in this article, and if you need repair or cleaning, clearly imagine the layout of the parts to do everything competently. Be sure to check with the manufacturer's instructions in this case.
