If you have installed a gas water heater in your apartment, then you are already used to the fact that hot water flows from the taps. But what if the flow reaches the temperature of boiling water? Why does the appliance heat the water so much? Do not rush to call the master. Having understood the causes of the problem, you can fix it yourself.
Why does the geyser get very hot
The use of a flow heater, as the column is also called, is quite advantageous. Gas is the cheapest type of fuel, so the operation of the device is cheaper than centralized water supply.
Regulators are located on the body of some models. One of them regulates the force of water pressure, the other – the gas supply. This sets the heating temperature. Experts recommend setting comfortable indicators no more than 42-50 degrees. At elevated temperatures, active deposition of salts on the heater parts begins.
Why is there very hot water coming out of a faucet? There are several reasons.
“Winter” function on
It’s all about how the column works. Keep in mind that the quality of heating is affected by the temperature of the liquid at the inlet. For example, the technical data sheet states that the device heats up to 35 degrees. In summer it can be +15°C at the entrance. This means that the liquid at the outlet will be 50 degrees. In the winter season, the figures are reduced.
Manufacturers have provided for this outcome by installing the Winter-Summer regulator on some columns. If you did not turn off the winter mode in the summer, then the heating temperature will exceed the specified norms – boiling water will flow from the tap.
Weak pressure
If either hot or cold water flows from the tap, the reason may be the insufficient pressure of the cold stream, poor pressure in the line. If this happens rarely, it can be attributed to temporary problems or simultaneous use by several residents. But if the pressure disappears regularly, contact the water utility or install a circulation pump.
blockages
Filter. Since the quality of the water in the water supply is poor, a cleaning filter is installed at the inlet to the system. It traps small debris, softens, cleanses of impurities. If the contents of the filter or its cartridge have not been changed for a long time, a liquid filled with potassium and magnesium salts enters the column. Settling on the details, scale leads to their breakage. Replace filter or cartridge.
Heat exchanger. Over time, the radiator becomes clogged with deposits, which leads to excessive heat. The part must be removed for cleaning. You can use special anti-scale products, or you can immerse the heat exchanger in a metal basin with a lemon solution. Warm it up on the stove for about half an hour.
How to clean a gas column, we wrote in one of the previous articles.
Plumbing system. It is necessary to check all connections, flexible hoses for clogging. If they have poor throughput, you need to clean the elements. The hoses are washed under running water. Pipes can be cleaned with reverse current or call the master.
Incorrectly installed regulator
Check if the gas supply knob is set to the maximum mark. Because of this, the water gets very hot. Return it to its normal position and see what has changed.
The mixer skips a little. Perhaps the mixer is not suitable for the power of the equipment, the shower head has too little capacity. In this case, it is impossible to adjust the temperature, you need to replace the nozzle.
Experts do not recommend diluting a hot stream with a cold one. So scale forms on the parts faster, the equipment fails.
We have considered the possible causes of such problems. When you turn on the equipment, follow the instructions: it clearly indicates which parameters you need to set.
