Cleaning the boiler

All those who live in a holiday village or in a village of urban type, or simply in country or private houses,such an adaptation as a boiler. Like all objects and aggregates, it clogs. Therefore it is extremely important to know how the boiler is cleaned. In fact, this is a fairly simple procedure, and we give you a chance to make sure of this yourself, just by reading this article.

How can I drain water from the boiler?

Sufficiently convenient when the water heater is located above the bathroom or in another place where a large capacity can be placed under this boiler without interference. Then you can not waste time on this procedure - drain the water directly before cleaning the boiler. You can do this simultaneously with the removal of the heater. But you should be aware that the installation of some storage units can create difficulties for you during such emptying.

Important! Drain at the same time with the removal of the heater is very convenient in those water heaters in which it is screwed straight into the tank. In other models it is necessary to unscrew a pair of nuts that hold the flange with TEN - in this case it is better to empty the container in advance.

If the boiler is connected correctly to the water supply, there will be no problems with the extraction of water for further cleaning. The algorithm for emptying the tank is as follows:

1. Disconnect the boiler from the electrical network, close the common tap, which is responsible for the water supply.
2. Close the cold water tap near the heater, then open the hot tap on the nearest mixer and wait until all water has drained out.
3. Connect a pipe to the drain pipe that is directed to the sewer, open the tap and drain the water.

Important! When there are no spouts, no taps, you can try to empty the tank with a safety valve. But in this case, cleaning the water heater can take a whole day. Therefore, it is better to wait until the water cools down, and then follow the above algorithm.

When there is no connection:

1. Disconnect the hot water supply pipe from the boiler, and then replace the bucket. In order for the water to flow, carefully unscrew the safety valve. At the very moment when the air starts to pass inside the tank, water will run out of the nozzle.
2. The valve can be completely removed and adjusted the intensity of the jet, overlapping the nipple with a finger.

Important! In this way, you will empty the tank relatively quickly. Under no circumstances, do not forget in the process of reverse assembly as it is supposed to withstand the scheme, so as not to waste your time next time.

Some recommendations for descaling and disassembling

By and large, the whole process of cleaning the boiler is considered to be quite simple, so it can easily be done with your own hands:

1. But first you need to disassemble and remove the heater, It is necessary to remove the decorative cover that covers its fastening, as well as the contacts from below.

Important! As a rule, it is fixed with a screw, while in some boiler models they are covered with a plastic panel.

1. When the screws are unscrewed and the cover is removed, the contacts and fastenings will open before you. In order not to remember the whole scheme of connection, just take a picture of it from several angles.
2. Next, disconnect the wires and the access to the thermostat opens before you. Usually it can simply be removed from the housing of TEN, in other models - you have to shoot them together. After unscrewing the fastening nuts or the tubular heater itself, carefully remove it from the tank.

Important! It is necessary to extract the heater from the heater very carefully, because the accumulated scum in the boiler often does not allow it to be done easily. In devices that have not been cleaned for a long time, one even has to pick up mud deposits, otherwise the element will not be able to be obtained.

Directly cleaning the

The main volume of the scale is concentrated near the heating element, but there is not much of it in the tank itself:

• If the contamination is very severe, when the walls of the tank are covered, try to eliminate the scale by hand. But remember that using abrasives to remove this scale from the enamel surface is not recommended.
• When this did not help, there is nowhere to go: remove the water heater and clean it with a variety of chemicals.

Important! Using the case, pay attention to the state of the magnesium anode, and if there is such a need, then replace it.

The usual algorithm for cleaning the boiler looks like this:

1. Remove the thick layer of scale from the surface of the heater, using a mechanical method, for example, with a knife.
2. After that cut off the neck of the plastic bottle, fill it with a warm mixture of citric acid and water, the proportion is 2 packets of acid per 2 liters of ordinary water.
3. Immerse the element inside the solution bottle and leave for a day. Upon passing this time, the heater will be both from the factory.
4. After this, collect the boiler, fill it with water and calmly operate it further.

Descaling agents in water heaters

In some cases, boiler cleaning for a variety of reasons requires a lot of labor, for example, for indirect heating boilers. Getting a copper heat exchanger out of it is not so easy. And with ordinary heaters of large capacity of adventure you will not be taken. In such situations, you can clean without disassembling and removing the device - using chemical means to eliminate dirt and plaque.

A few words about how to eliminate the scum inside the boiler:

• We have already told you about citric acid, only in this case it is necessary to increase the concentration of the solution.
• In addition to citric acid, a variety of chemical products are available for sale, which are intended for this purpose. One of these tools is the Master Boiler, which has proved itself quite well in the market of means for removing dirt and scale inside boilers.

But after purchasing a special solution, the question always arises - how to fill it inside the tank? It turns out that everything is simple enough. True, the boiler must necessarily be connected to the water pipe correctly, according to the scheme. Then:

1. Through the hot water tap, empty the container by one-third.
2. Then connect the hose to the drain fitting.
3. Through it, pour the chemical agent you have chosen into the tank.

Important! Make sure that the end of the hose with the watering can is raised above the water heater.

We clean the boiler with dry heaters

Simply put, the procedure for cleaning the water heater, which is equipped with a so-called dry TEN, does not differ from the usual one in any way. If you have decided to disassemble the device for this procedure, the ceramic element should not be mechanically scrubbed, because it must be treated with extreme caution. It is better to simply immerse it in a concentrated solution of acetic or citric acid and wait until the scum dissolves. You can also use the industrial chemistry from the store.

In this article we have told you how to properly disassemble a water heater for cleaning a boiler and the better this process is performed. Do this regularly, and then you will not have interruptions with hot water for a very long time.
