Why clean the boiler?

Before cleaning the water heater from scale at home - Ariston or any other similar, you need to understand why.

If a heater is used for a long time and its heating element and internal surface are not cleaned, various kinds of breakage are possible. But all of them will arise because of the accumulation of salt deposits in the water on the surface of the TEN.

Important! The boiler must be cleaned at least once every 3 years, or if it already signals an impending disaster. With hard water, it is recommended to clean it once a year.

Signals:

• Water began to heat up more slowly.
• The water temperature has changed.
• Boiler increased power consumption.
• The storage tank began to overheat.
• If the device is frequently turned on and off.
• If there is a hiss when you heat up the water.

Cleaning options

In order to clean the boiler, it is necessary to know how to clean it. In general, there are two of them: chemical and mechanical:

1. The mechanical variant is more complicated, since it requires more manual work, and if the removal of the heating element is not careful, it will be necessary to change the heater. Also, if improperly connected, a short circuit is possible.
2. The chemical method is easier, it involves the use of special compounds. In this case, it is not necessary to remove the heating element.

Consider these methods in more detail.

Important! The very first thing you need to do before you clean the water heater from scale at home is to prepare: turn off the boiler from the mains and drain the remaining water.

Drain the water:

1. If the boiler is located above the bathroom - you are lucky, the water can be easily drained directly into it.
2. If not, you'll have to stock up with a large capacity. In this way, you can save a lot of time and drain the water just before cleaning.
3. If the boiler is positioned so that it can not be replaced with a container, you will have to work hard.

Procedure:

1. Disconnect the current supply, shut off the tap, through which water enters the accumulator.
2. Close to the heater close the cold water tap, turn on the mixer hot water, wait until it spills.
3. Find a short tube - drain fitting, attach a hose to it, first putting it into a container or a drain hole.
4. Open the valve on the boiler, drain the water.
5. If there are no taps and drainage pipes, it is possible to drain the water using a safety valve. But then the process can take more than 10 hours. Therefore, it is easier to wait for the liquid to cool and drain the water according to the listed items.
6. The only difference in the absence of a fitting - it is necessary to disconnect the hot water hose, and substitute any volumetric capacity. In order for the liquid to start leaving the TEN, it is necessary to unscrew the fuse valve carefully. As soon as air gets inside the heater, water will flow from the nozzle. The valve can be disconnected, and adjust the water flow by plugging a cold water connection with a finger.

After draining the water, you can start cleaning the heater. How to clean the water heater, find out later.

Dry TEN differs from submerged( wet) in that it is enclosed in a flask and contacts the water not directly but through it. The essence of cleaning of this type of heaters does not differ from the traditional method.

The only difference is that mechanically remove the scum is not worth it, because the risk of damaging the protection of the bulb is very high. An excellent option for cleaning this heater is to simply dip it into a solution of citric acid, vinegar or a special cleaner.

Magnesium anode

When parsing the heater, it is important to pay attention to another key element necessary for its operation. It is a magnesium anode, which is located next to the TEN.The anode protects the device from rust, and gradually breaks down when the boiler is running.

Replacement is simple enough: the anode is twisted, and a new one is put in its place. In order not to disassemble the device several times a year, it is convenient to replace the element together with cleaning the heater.

Important! If the tank starts leaking earlier than cleaning is required, it is a signal to immediately replace the element.
