Geyser Thermostat Setting – Problems & Solutions

Updated by

Do you want to lower or increase the temperature in your water heater? Well, that is possible by tweaking the thermostat. If you have an old conventional type of geyser, it can be hard to find, but tweaking the thermostat may not be a problem if you have the latest model.

Do you know what a thermostat is? If you don’t, you will, after reading this article. Here you’ll learn where to find a thermostat and how to change settings in a different type of geysers. If you’re interested, let’s dive right in.

What is a Thermostat?

A Thermostat in a water heater is a simple device that maintains the water heater temperature. If you set the temperature in your thermostat at 100 degrees, it will automatically turn off the water heater when the above temperature is achieved.

And when the water’s temperature becomes less than 60 degrees, it automatically turns on and lets the geyser heat the water until it reaches 60 degrees. All in all, it’s a device that helps you heat water at the set temperature. And once that level is achieved, it turns off automatically.

How do I Find a Thermostat in my Water Heater?

It depends on the kind of water heater you have at home. Usually, there are two types of water heaters available: –

Visible Thermostat: In this kind of water heaters, the thermostat is placed on the outside. It means you can use the knob to rotate and set the temperature.

Invisible Thermostat: Here, invisible means not visible from the outside. Such water heaters have a thermostat on the inside. You cannot change its setting on your own. However, it’s set at 55-60 degrees and has a green and red light to indicate whether the water is hot enough or not.

What is the Ideal Temperature for a Water Heater?

Although you can tweak the temperature anywhere between 40-75 degrees, 50 degrees is considered an ideal temperature. You can increase the temperature to get hotter water from the water heater, but it’s not advised. More heat increases the risk of you getting burnt and raises the energy bills too.

You can also use a solar water heater, which will act as the backup to minimize energy consumption. However, it can create a problem on cloudy days. It’s because solar water heaters require direct sunlight to heat the water appropriately.

How to Adjust an Electric Geyser Temperature Thermostat Setting

Here are the steps to change thermostat temperature in an electric water heater: –

  • You need to first cut off the electric supply to your water heater. You can do that by simply pulling the plug off the switch.
  • Now, you need to find the thermostat. It is usually placed under the control panel held together by screws. You can remove the control panel and access the thermostat. If your heater is insulated, you need to first remove the insulation, and then you can access the thermostat.

The thermostat usually comes with dials. So, you need to check what does the dial read.

  • Once you can access the thermostat, change the temperature settings to achieve what you want. And if there are two thermostats, make sure both have the same temperature settings.
  • After you’re done changing the settings, place the control panel and the screws back. And then turn on the water heater.
  • Now, after 3-4 hours, test whether or not the water is heated to the extent you wanted. If not, repeat the above steps and try again.

How to Adjust Gas Geyser Temperature Thermostat Setting

Tweaking a gas geyser thermostat is way easier. However, you need to follow the below steps for the best results: –

  • The thermostat knob is usually visible in the gas geyser. So, locate the knob and adjust it according to the temperature you wish.
  • After that, you can leave it for 3-4 hours and test it again. If the water has the desired temperature, you’re done. Otherwise, you can follow the steps again.

Common Geyser Thermostat Problems and their Solutions

Here are some common thermostat problems and their corresponding solutions: –

1. Water not heating at the desired temperature

Problem: Water not heating sufficiently is the most common problem a water heater thermostat faces. It can be due to the low-temperature settings of the thermostat. It can also be due to a faulty thermostat.

Solution: If the temperature is set too low, you can increase it by following the below steps: –

  • Cut the electric supply, if the water heater is electric.
  • Find the thermostat and increase the temperature by turning the knob.
  • Check whether or not the water is heating to the desired level.
  • If not, try increasing the temperature further.

However, if nothing happens even after setting the temperature, your thermostat may be faulty. And for this, you need to call a plumber.

2. Thermostat is stuck

Problem: After pronged usage or due to rusting, sometimes the thermostat knob gets stuck at one point. At this point, you’ll either get very hot or very cold water.

Solution: If the temperature of the water coming from the water heater is ideal, let it be. Otherwise, you can try turning the knob on your own. If the knob is badly stuck, you should call an expert and stop trying it on your own.

3. The thermostat is stuck at a particular point

Problem: Sometimes, the thermostat is not entirely stuck. It moves to some extent and then gets stuck at that particular point.

Solution: You can first try moving the thermostat by putting some pressure. If nothing happens, you can simply replace the thermostat knob or the thermostat altogether.

Conclusion

The thermostat is a great device if you know its application in a water heater. You can tweak the settings and get the water heated at the desired temperature. If you don’t know how to do that, read through this article. You can follow the steps and get it done in no time.

However, if you have no knowledge, you can always refer to a local plumber. If you find the above information useful enough, please share it with others.
