The water heater, or as it is also called, the boiler - is a large enough capacity, designed to heat water. But, nevertheless, do not forget that all appliances need care and the boiler is no exception. However, do not worry, the maintenance of the water heater is not so difficult, so you can repair and clean it yourself, without the help of experts. It is worth noting that, despite the fact that there are a lot of boilers of different price categories and modifications on sale, their design is almost the same. Therefore, the damage and the way of care, therefore, do not differ in principle. This article will discuss how to clean a water heater from scale.
Sequence of work
Cleaning the boiler is a necessary process that should be performed at least once a year. The thing is that the more impurities in the water, the more often scale is formed. Check it out easily, just take a look at your kettle, in which you warm water. How often does scaling form in it? The same happens with the water heater.
The execution of cleaning is divided into the following stages:
- Disconnection of the boiler from the power supply.
- Draining.
- Cleaning the boiler.
- Assembly and connection.
Disassembly and cleaning
Take, for example, the water heater company Termeks. To begin, de-energize the boiler - simply unplug the power cord and disconnect the wires from the thermostat. After that you can start to drain. To start, shut off the cold water supply to the unit. Then put a hose over the drain valve and put it into the toilet, sink or basin and open the water supply valve. Wait for all the water to drain, then you can remove the cover.
To drain the water is a special faucet, open it, and the water will flow out itself.
Then you need to unscrew the fastening screw located in the center or behind the sticker. Now the cover can be removed. Before you control board. Disconnect the wiring further (phase, ground and zero).
In order not to confuse where to install which wire after cleaning, they can be pre-photographed.
Finally, unscrew the pan and take out the heater. If you have not been cleaning for many years, then you need to replace it by buying a new one. Do not be surprised if the scale will be very much. To start, put it in a bucket or trash can. After that, wash the boiler from the inside. If the scale is cleaned poorly, you can use special tools, after which the boiler must always be washed with water. Abrasive detergents can not be used, as they severely damage the anti-corrosion coating. At home you can use citric acid.
Prepare such cleaning tools in advance:
- flat screwdriver;
- brush;
- rag;
- key;
- hose;
- cleaning agent;
- liquid container.
Having made such cleaning, you increase the term of operation of the device. Moreover, the water in it will heat up much faster, which will reduce your energy costs. Note that the water in it will also be somewhat more, since the scale that was inside has been removed.
Boiler assembly
After the end of the work, the assembly should be carried out in reverse order Before filling the tank, do not forget to open the hot water tap on the mixer. After a short time, water will flow out of it - this means that the container is full.
Upon completion of the work and after the boiler is filled with water, wait 2–3 hours, as a flow in the area of the flange mounting is possible. If the water does not leak, then you can turn on the power supply.
According to this scheme, you can clean any boiler, regardless of the manufacturer. This could be Termex, Ariston, Bosch and others. This scheme is universal and does not require a special approach to each boiler.
If you are accustomed to do everything with your own hands, then remember that you do not need to pay someone money. It is also possible to clean the boiler by yourself, just a little time and effort is enough. Do not forget that if other people can do it, so can you!
