How does a tankless water heater work?
A tankless gas water heater heats incoming water in the pipe as it is needed. It uses a heat exchanger (a device that transfers heat from one place to another) to transfer heat generated by the gas burner to the water flowing through your pipe. As you turn on your faucet, the incoming flow of water activates the heat exchanger and moves around it, ...
Why is the hot water discharge pipe not as long as the cold water supply pipe?
The hot water discharge pipe is not as long as the cold water supply pipe because it reaches for the hottest water at the top of the tank. A gas regulator controls the gas burner that does the work of heating water in the tank . The regulator is typically mounted on the side of the water heater tank, and it is designed with a thermostat ...
How does a cold water tank work?
The cold water supply line constantly supplies cold water into the tank. As the supply goes on, the dense cold water at the bottom of the tank, through the help of the gas burner, gets warm and eventually hot (depending on the present temperature). By the time a certain level of hotness is achieved, the water would have started rising in the tank.
