How to drain the water from the boiler

In apartments, private houses and cottages often install storage water heaters, through which tenants can be provided with hot water. If we talk about apartments, then the use of a boiler in them is in demand only in the summer period, when hot water is turned off for seasonal communications repair work. As a rule, centralized provision of hot water is not provided in the houses, so boilers are used regardless of the season. There are several reasons when you need to drain water from the drive. Therefore, it is very important to know how to drain the water from the boiler. This will be discussed in the article.

The reasons for which you need to drain water

Before draining the water from the water heater, make sure to hold this event is really necessary. There are situations when it is undesirable to do it. About situations in which you need and do not need to drain the water and talk further.

When need

If you need to leave the boiler for the winter in an unheated room, then the water from the boiler must be drained. The fact is that water already at a temperature of +5? C begins to crystallize. If ice forms in the storage tank of the water heater, then the device is likely to break.

Independently drain the water, repair the boiler or replace any spare parts only after the warranty period. You can do this work only if you drain the water from the tank.

Before cleaning the scale, the tank must also be freed from water. This procedure should be repeated at least once every 5 years. But, if the quality of the heated water is below average, then the heater should be cleaned more often.

In a tank with sediment, the water heats up much more slowly. And this means that you will pay more money for electricity due to the increase in energy costs. The same principle works in the operation of any equipment for heating water.

When not needed

If you need to turn off the device for the summer, that is, for the warm season, not involving low temperatures, then there is no need to drain water from it. It is not even advisable, because the water tank without water is more susceptible to corrosion. Moreover, if after a vacation it happens that you forget about the lack of contents in the tank and turn it on, it will simply burn.

Suppose you had a boiler off for some time and the water in it stagnated. In this case, it is not necessary to merge it. Simply pass cold water through the tank several times.

It is recommended to rinse the tank once every 2-3 months. This can be done by passing about 100 liters of cold water through it.

If the water heater is still under warranty, then it is better not to pour water from it yourself. The fact is that if in the future you will need the maintenance of the device by service workers, then after your initiative, they will not take into account the validity of the warranty card. And for the service you have to pay. If you need to fix the damage, then contact the service center, and do not be wise how to do everything yourself.

If you wanted to disassemble the boiler out of curiosity, then perhaps not worth it. Remember, household appliances and adventure concepts are incompatible.

Differences plum depending on the design

Manufacturers of boilers launch devices with their own design features. It is worth noting that the instructions for use of the heater has instructions for draining water. Next, we consider the nuances in the implementation of the drain on the example of popular models of boilers.

Thermostat

Перед осуществлением слива воды с водонагревателя Thermostat ознакомьтесь к приложенной к устройству инструкции, если, конечно, вы не приобрели Б/У устройство. Даже если и так, то не отчаивайтесь. Ниже описано как осуществить слив воды с бойлера Thermostat:

• If the water is already glass, close the mixer tap.
• Unscrew the nuts at the water supply point at the bottom of the check valve. The easiest way to do this is with an adjustable wrench.
• Then to the vacant pipe should be connected to a hose with which you can drain the remaining water into the sewer.
• After unscrewing the nut from the nozzle, air enters the tank and water flows out through the hose.

If the water from the tank is already glass, turn on the cold water, and then rinse the tank.

Ariston

Gorenje

The principle of draining the boiler water from the gorenje company is similar to the cases described above. As well as believes first you need to de-energize the device. Then open the valve on the hot water mixer.

After the hot water is drained, connect the hose to the cold water tap. At the same time, send its opposite end to the nearest sewer drain or to a suitable container.

After opening the drain valve and supplying air to the tank, the water heater will begin to empty. All this will take you about 10 minutes.

Another option for draining water from a Gorenje boiler is through a safety valve. This, of course, is an easy way, but if time is more expensive to you, it is better to drain the water as described above. Since the water flows through the safety valve for a very long time.

Some models of water heaters are not equipped with a special flag on the safety valve. If this is the case in your case, then find a spring inside the valve and squeeze it out with a tube. Do not unscrew the valve.
