Using a water heater makes life easier for residents of apartments and houses. You can get hot water around the clock in the kitchen or in the bathroom. But what if there is an unpleasant smell of water from the boiler? Why does the contents of the tank stink? This does not mean that the boiler is bad, the reason may be in the water itself. Consider the possible options and ways to address them.
Why water smells bad
It happens that users complain about the smell of hydrogen sulfide from the boiler. It seems that the water is rotten. Before you begin to search for the causes and eliminate them, think:
- What temperature regime are you using.
- How often the boiler is operated.
- How long has the filling of the filter changed.
- Was the water tested for bacteria.
Conclusions will help determine the cause of unpleasant phenomena. Here are the main ones:
- Chemical reaction. Tap water contains sulfides. Once in the tank where the magnesium anode is installed, they react. As a result, hydrogen sulfide is produced and the water goes dry.
- Rare use of a water heater. If the device is installed in a country house or in another room where it is rarely used, the liquid stagnates, bacteria - Legionella begin to develop. In the process of their life, an unpleasant odor appears.
- Poor content warming up. If you set the temperature to less than 30-40 degrees to get hot water, microorganisms develop even more actively.
- The initial content of hydrogen sulfide in water. You can check this at home. Turn on the tap and let flow a few minutes. Fill the bottle with water, shake and smell. Hydrogen sulfide gives rotten eggs.
If you get water from a well and a well, try deepening the hole to get away from the gas layer. If a similar problem arose in the apartment, you need to write a complaint to the communal institution.
- Excessive scale formation also contributes to the development of microorganisms.
The problem area may be not only an indirect or electric boiler, but also pipes.
How to fix the problem
If you rarely use the device, then drain water from the tank during the absence - it will not stagnate. How to drain water from a boiler, read in a separate article.
Periodically set the highest temperature, let the contents warm up well. Heat will destroy the bacteria.
If the contents still decay, you need to clean the inner walls and body parts from scale. For this:
- Unplug the appliance.
- Drain the liquid.
- Unscrew the fasteners of the heating element flange (at the lower location).
- Pull out the heater. If the coating is strong, clean it with a knife, then dip it into a solution of citric acid until it is completely clean.
- How to rinse the case? The walls of the tank are washed with a soft sponge and cleaned with a shower. In advanced cases, you need to buy a special anti-scale agent. Pour it in the indicated ratio with the tank for a while. Then rinse off.
It is important to replace the magnesium anode in a timely manner. In modern models, there are indicators that indicate when it is time to replace. Otherwise, once every six months you should look under the cover and check the condition of the rod.
For hard water with a high content of impurities, install a filter. How to choose a filter for a boiler, read in a separate publication. They come in different types and principles of action. Periodically, the contents of the flask are replaced.
To completely disinfect the system, an anti-mildew agent is added to the filter flask. This cleans both the heater and the pipes. After such cleaning, rinse the device several times with warm water.
Proper operation of the equipment avoids many problems. Therefore, do not be lazy to look at the instructions before turning on the heater. The video will help you maintain the instrument in order:
