Water Heater making noise
- In any, even new and serviceable storage water heater, water is buzzing due to the process of the convention. The heating element, installed at the bottom of the tank, heats the water. It forms bubbles that rise upward and clap when they enter the upper, colder layers. The same happens when the kettle is boiling. This process is natural, it is impossible to fight against it.
- A thick layer of scale has formed on the heater. At the same time salt deposits are heated first, and water is already heated from them. At the same time, part of the liquid falls under the scale layer, and whistles when it boils and exits.
- Too much pressure in the water supply. At the same time, pipes can make noise. This increases the load on the water heater and reduces the life of the heater. It is necessary to install a pressure reducer, which will reduce it if necessary.
- The check valve is noisy. It is necessary that the water from the boiler does not go back to the water supply. But over time, the valve wears out, becomes covered with scum and begins to flow a little, which is accompanied by a buzz. You need to replace it with a new one or clean it.
- Whistle bypass valve. When heated, the water expands. To prevent tank rupture, each water heater has a bypass valve, which, under excessive pressure, discharges water into the sewer, which is sometimes accompanied by a whistle. It must be replaced.
- The raised noise can be, if the boiler air, that is in it together with water air gets. Usually this is of a short duration and takes place when the water supply is restored. The same effect occurs if a large amount of oxygen is initially dissolved in water.
