Checking the water
The frequency of cleaning the water heater - usually once a year or even two. Understand that it's time to clean the water heater will help the following. To do this, you need to drain from the boiler about half-liters and check its color. The reddish tint indicates the presence of a rust on the internal parts, a darker shade indicates the presence of slags. In both cases, anticorrosion treatment is necessary.
You can arrange a water test in another way. Fill with water two glass vessels with a screw cap. In one, pour water from the boiler, in the other - from the tap. In each vasodopustite several steel nails. After a few days, the nails in the water will be covered with rust. In the water from the boiler, if it contains a sufficient amount of anti-corrosion agent, they should remain shiny. If you had to watch another outcome of the events, an anticorrosive agent must be added to the system. It is important to use exactly the composition that is already present in the system. If, for some reason, you do not know this compound, it is better to completely dry the system and refill with water and an inhibitor.
Removal of scale from the heating element
Periodically it is necessary to clean the water heater from scale. Than it is caused? Scum on the TENe exerts its influence on overheating, on increasing the consumed electric power and thermal insulation of the thermostat iTEN.
The algorithm of actions is as follows:
- we disconnect the boiler from the mains;
- block the supply of cold water;
- open the hot water tap;
- open the safety valve (if the handle is not supposed to be drained, it should be dismantled);
- open the nuts that hold the flange;
- take out the flange;
- carefully remove scale from TEN manually or by using cleaning agents;
- you can remove the scum from the tank, but only slightly. Why lightly? The scale on the surface of the tank acts as an additional protection against corrosion.
Other indications for cleaning the water heater
- During operation, the water heater generates a loud sound.
- The water from the water heater has a specific hydrogen sulphide smell.
- The water heater heats the water for a long time or chastovklyuchaetsya / disconnects.
To prolong the life of the water heater, do not heat water in it for more than 60-70 degrees. If the water heater is used intensively at maximum power, be prepared for the fact that the build-up and scale on the heating element and the tank will be much larger.
