As winter comes, It is very difficult for everyone to take bath or wash hands with cool water. Every house needs a water geyser. Gone are the days when people prefer to hot water on wooden chullah. We are living in a time where every minute has a lot of value. So electric, gas, solar, and many more types of geysers are there in the market. Lets see What is a Geyser?
An electric geyser uses electricity as an energy source to heat the water above room temperature. The geysers are used domestically in bathing, cleaning, cooking, and many more. Water heaters are also known as water heat exchangers, geysers, calorifiers, and many more names.
Hows a geyser work
- A geyser has mainly three parts. Heating elements, thermostat, and storage tank. The heating element is a very important part that can be damaged due to hard water. Many geysers nowadays come in coated with glass are effective against hard water and increase the life of the geyser.
- The storage tank holds the hot water. It needs to be strong. It comes in two types of material: stainless steel and vitreous enamel. Stainless steel storage tanks are obsolete nowadays. Vitreous enamel is new and advanced and coated with polymers that can’t be damaged by hard water. The thermostat decides when to start or stop the heating.
- For example, You ON the geyser, The water temperature is 13 degrees Celcius. Then the thermostat detects it and the heating element starts heating the water. When the water temperature reaches 60 degrees Celcius, the thermostat indicates the heating element to stop heating more and cut it out. If you forgot to switch OFF the geyser, It starts heating after a few minutes to maintain the temperature of the water to 60 degrees Celcius.
