If we talk about the traditional water heaters, they almost work in a similar manner and the aspect that creates the difference is the source of power. And, the source of power can be gas, electricity, and solar energy. But, currently, there are multiple brands that produce water heaters and it becomes a tough nut to crack to find the best water heater brands and prices. So, here is a complete guide about the water heater function, to make you aware of the basis on which you should select the best cheap water heater.
What are the vitalities of a water heater?
Both electric and gas water heaters are known to have not one but many components in common like:
- Internal anode rod
- TPR Valve
- Pipes and Fittings
- Drain Valve
- Dip Tube
And, in both cases, the insulation is done on the internal tank to keep the water warm and hot for a longer time. Talking about the thermostat, the electric water heater has a separate thermostat and gas one has it in the gas control valve. In case of emergency, the gas water heaters have the mechanism of the thermocouple to end the supply of gas which is why it is regarded as the best cheap water heater 2020 for Indian homes.
The working of an electric water heater
When you open an electric water heater, you will find that the thermostat is located beside the internal tank and when this thermostat gets the indication that the temperature has gone below the threshold, it get the switch to make the flow of electricity in the heating element. And, in the water, the heating element is present which works by letting the electricity pass through the resistant material which in turn converts the energy into heat that warms up the water. The smart technology of auto-shut thermostat switches of the electricity supply once the water gets warm. You can search for the best electric water heater brands and prices, and select accordingly, the best-suited one for you.
The working of a gas water heater
If you think gas water heaters do not come with a thermostat then that is wrong. It comes with a tube made of copper which has a mercury sensor in it. And, the use of thermocouple in it is to not allow the gas to flow if the pilot light is not burning. If the temperature in the internal tank falls down, the gas valve opens to allow the flow of gas to maintain the temperature. Once, the temperature reaches the threshold, it instructs the thermostat to signal the gas valve to close it for the flow of gas. And, this is how gas water heater function.
Solar energy powered water heater
It is the least used and rarely in-demand water heater because it is only a circulating system which causes the water to flow through a concentrating device which is always exposed to sunlight which in turn provides heat in the center of the solar water heater.
