How to drain water from a water heater ariston

Many city dwellers face the problem of the lack of hot water in the summer due to repairs of boiler rooms or the fact that there is water in the tap, but it is barely warm. The latter phenomenon is often observed in residents of the upper floors. You do not want to pay for a non-existent service, and people use electric water heaters to provide themselves with hot water. One of the most popular brands of such devices is Ariston. It is a reliable and easy to use device. With timely preventive maintenance, it will serve for many years. For example, you need to know how to drain the water from the water heater Ariston, which will be discussed in this article.

How does the boiler work?

In order to understand how to properly operate and maintain the device, consider its internal structure. Most water heaters consist of the following components:

• Accumulative tank in which there is a water heating. To increase the time of cooling water tank is placed in a heat-insulated housing.
• Delivery tube Through it cold water enters the storage tank.
• Discharge tube. It serves to supply hot water to the water supply system.
• Safety valve. It is installed on the cold water pipeline. This valve prevents water from leaking back into the system and allows you to relieve excess water pressure in the boiler. Thanks to this device, the permissible pressure is always maintained in the storage tank.

For ease of use of the device on cold and hot water pipelines, install shut-off valves or an air suction valve on a hot pipeline and a drain valve on a cold pipeline.

Reasons for needing to drain

During use of the electric water heater there is a need to drain water from it. This procedure will have to be done if the device fails, for example, the heating element deteriorates. Often, boilers are installed at cottages or in homes that the owners use periodically. The rest of the time, the boiler stays in an unheated room. In the first case, water drainage is necessary, since all the equipment requiring repair is located at the bottom of the device. When the heating element, the anode is changed, or the accumulated dirt is cleaned, the case is depressurized. If the water is not drained, then it will all pour out on the floor. In the second case, the water is drained in order to prevent water from freezing inside the storage tank. One of the properties of water - when freezing to increase in volume. Naturally, it can break the tank. In all other cases, the water heater must be filled with water. This will save the tank from damage.

Process

If you have problems with the boiler, you may be asked how to drain the water from the Ariston water heater? To drain water from the water heater, it is necessary to depressurize the boiler and run air into it so that no vacuum is created in it. This is very easy to do:

1. Turn off the appliance from the network. It is impossible to drain the water from the included boiler for two reasons. Firstly, for security reasons. If there is no grounding, if the electrical part is damaged, the current can pierce the body and injure a person. Fatal outcome is not excluded. Secondly, without water, the included heating element will quickly blow. It is not designed to heat the air.
2. If the water in the boiler is hot, then first drain it through the mixer, pushing it with cold water, and then begin the procedure of draining the water.
3. Shut off the supply shut-off valve. This will not allow cold water to replenish the boiler, because with the faucet open, how much hot water you drain, as much cold water will flow into it.
4. Relieve pressure from the nearest mixer by draining hot water. This is done in order to remove heated water from the boiler, which will shorten the discharge time.
5. Open the valve on the hot water pipe, thus triggering air into the boiler. Depressurization of the device through the start of air will fill the vacated space, and displace water.
6. Attach the hose to the valve for discharge in cold water and lower it into the sewer or another large enough capacity. Do not forget that the water is very hot and can burn. If time allows, it is better to wait until it cools down.
7. Open the drain valve, through which the water from the boiler will pour out.

Now you need to wait until the water from the boiler stops flowing. After that, the valves can be closed. But it must be remembered that in this way it is impossible to drain all the water.

Some liquid and dirt at the bottom of the boiler will still remain, so when opening the device, make sure that there is a bucket nearby. The residuals are drained into it.
