How to Troubleshoot a Defective Thermostat on An Electric Water Heater

Troubleshooting the thermostat on your water heater might look difficult. But with this guide, you can handle this task without contacting a professional.

How To Replace A Faulty Thermostat On An Electric Water Heater

Changing the thermostat on an electric water heater is as easy as installing an electric switch. After knowing how to test a thermostat, you can even handle the repairs without emptying the storage tank. However, you must turn off the power supply and check the wires for voltage before anything to prevent possible accidents.

How To Test Water Heater Thermostat

If you want to test a thermostat on an electric water heater, you will also need to check the heating element. This is important, especially as open and grounded heating elements result in inaccurate tests. To look for faults, you will need to use a screwdriver. You will also need to check the water heater thermostat with digital multimeter tools. Now let us get started with the following steps on how to test a water heater with multimeter.

7 Steps To Test Water Heater Thermostat

When you check your electric water heater, you will notice two thermostats on the unit-one at the top, and one at the bottom. Each of these devices controls two different heating elements.

How do I find a Thermostat in my water heater？

Water heaters available in Indian markets are of two kinds: one with thermostat setting visible and is changeable and the other where thermostat is not visible from outside and you cannot make any setting changes. Those with changeable settings have knobs to rotate (as shown in the picture below) to change the temperature setting. Those that do not have changeable settings, mostly have a default temperature setting of 55-60 degree centigrade and have green and red lights to indicate if the water heater is heating water or not.

LinkTap G2 switch

As we mentioned at the outset, the LinkTap G2 is an upgraded version of the original LinkTap. If you were a fan of the original, you’ll already be familiar with the design. This is a two-part system, consisting of the timer itself along with a hub unit. The hub is compact and rectangular, with a blue-grey housing. It looks like a small internet switch, with ports for data and power on one end and lights on the front. A single G2 hub – LinkTap calls it a “gateway” – can control up to 15 timers. This makes it suitable for use on large properties as well as individual lawns.

What is a smart thermostat?

A smart thermostat, also known as a connected or communicating thermostat, allows you to create automatic and programmable temperature settings based on daily schedules, weather conditions, and heating and cooling needs. Some Wi-Fi thermostats have this advanced functionality, but not all do.

The Best Smart Thermostat

A smart thermostat does the thinking you don’t want to do. It can learn your schedule, turn itself down when nobody is home, and balance temperatures around your home to make you comfier while using less energy . Our extensive testing shows that the T18XUTW-7-WIFI(TY) Thermostat is the best smart thermostat because it manages your home with the least amount of input, it’s simple to use, and it has the best design of all the thermostats we’ve tested.
