Solutions For Gas Water Heaters Not Hot

The most common thing about gas water heaters is that the water is not hot. What causes overheating and how to fix it?

1. Too much scale in the water tank

Too much scale in the water tank is one of the reasons why the temperature of the water heater does not go up. Too thick water and alkali will affect the heat conduction. However, in general, the water tank is fouled, and the temperature is usually lowered slowly, rather than a sudden poor circulation.

Solution: Open the water tank and clean the scale.

2. Gas battery power is too low

If the gas water heater at home uses batteries, the water heater will not work properly when the power is insufficient, and the water temperature will naturally not reach the temperature that needs to be used.

Solution: Replace the battery with a new one.

3. Excessive water output

When the pipeline pressure is too large and the diameter of the pipeline is too large, when the heating rate of the water heater cannot keep up with the water outlet rate, the supply of hot water to the water heater will be insufficient and the water will not be hot.

Solution: adjust the rotary switch button of the water heater, close the valve of the water inlet pipe and increase the set temperature of the water heater.

4. The temperature sensor is out of order or damaged

Once the thermostat is broken or malfunctioning, the accurate temperature cannot be detected, and the system will think that the temperature has been reached, resulting in no heating.

Solution: replace the thermostat directly.

5. There are foreign objects in the gas pipe

There is a foreign body in the gas pipeline, and the water heater cannot push the micro switch. At this time, the water temperature needs to be adjusted to a high level to promote the ignition, and the water temperature cannot go up.

Solution: Remove the water inlet pipe, remove the filter at the water inlet interface, clean it, and then reinstall it.

6. Low gas pressure

The air source is insufficient, the flame is too small, and the water temperature is not easy to rise. The gas pipeline is blocked and the gas pipeline pressure is low. This situation is especially obvious in winter. You can check the integrated stove in your home to see if there is any abnormality in the gas pressure.

Solution: The low gas pressure is sometimes caused by the peak period of gas consumption and the insufficient supply of pipeline gas. It is enough to stagger the peak period. If the gas pipeline is blocked, ask the gas company to check the gas pipeline pressure.

7. Improper settings

There are generally three water temperature adjustment switches for gas water heaters: water volume adjustment switch, fire power adjustment switch, and winter and summer switches.

Solution: Adjust in time according to seasonal changes and temperature needs to ensure normal water temperature.
