A geyser, also known as a water heater, is an apparatus used to heat water. The main principle of how a geyser works is converting electrical energy into heat energy by using heating elements. A thermostat, on the other hand, is the part that assists in controlling and maintaining the water temperature obtained when the geyser does its work. It automatically powers the geyser on and off once it reaches the set heating level.
A geyser comprises of a water tank with two pipes fitted on the tank. One pipe act as an inlet of cold water while the other is an outlet for the hot water. The water tank contains heating elements that are regulated by thermostats. The main purpose of the thermostat is ensuring the water does not heat above the temperature value that is set. The water tank has a covering of insulating material bounded inside a metal covering.
The heating elements in the geyser do not work at the same time, and each has its particular thermostat. The top heating component functions first until the upper tank gets hot. The function is then shifted to the bottom heating component. The thermostat primarily has two metals, each with a different coefficient of heat expansion.
A geyser is one of the essential appliances you need in your home, especially if you experience cold seasons. However, if the thermostat becomes faulty, you could experience problems like insufficient heating of water. This could also lead to your water heater remaining on even after attaining the set heating level or not get power at all.
Therefore, for you to enjoy using your water heater, it is essential to regularly test your geyser thermostat and do repairs where necessary, to ensure it’s in the best working condition. The best testing device is a multimeter.
A multimeter is an electronic device used to measure resistance, voltage, current, and other value. One of the reasons why multimeters are preferable is because you can use them for simple tests as well as sophisticated tests to detect faults in electronic items. Multimeters are of two different types, analog multimeters, and digital multimeters.
These are meters that use analog techniques to display measurement readings. They have a graduated scale and a needle that moves over it. Analog multimeters are mainly used in detecting slow voltage changes. They have high sensitivity and low resistance, which makes them exceptional.
Unlike analog multimeters that use a moving needle, digital multimeters are electronic meters that display readings on a screen. They are mostly preferred due to their high accuracy, high digital resistance, and the fact that they are easy to read. These multimeters are expensive than analog multimeters.
A geyser has two thermostats, the upper thermostat, and the lower thermostat. Before replacing your thermostat, you need to test each one of them separately to determine whether both are defective or only one. When checking your thermostat, the main thing you need to examine is the resistance of the thermostat. Here are the simple steps you need to follow to efficiently use a digital multimeter to check if the thermostat is functional.
It is essential to know that some multimeters will read the resistance of their internal fuse. That means that instead of the normal reading of zero ohms for a good thermostat, the meter reads 0.5 ohms.
Your meter reads other than zero or infinite, depending on whether the thermostat has closed or open contacts, it signifies that your thermostat is faulty. Thus, it would be best if you replaced them.
Having a water heater that is not functioning well can be frustrating for you. It is, therefore, essential for you to regularly test your geyser thermostat, which is the leading cause for defectiveness in your water heater, to ensure a well-functioning geyser. However, if your thermostats are in good condition and still the heater is not working well, then you need to check the other elements.
