How does a gas water heater system work?
View Full Profile. In a gas water heater, two different systems work to supply your hot water. The gas system, which connects to a propane tank or a utility company, provides the energy for heating. The plumbing system, which includes a safety mechanism to prevent explosions, circulates cold water into the tank and hot water out of it.
Why does a gas water heater need a vent?
Because the combustion of gas produces dangerous fumes, a gas water heater needs a venting system. The vent collects rising combustion gases and directs them safely out of the building. Proper circulation through this vent is critical to efficient combustion and heating.
How does the thermocouple on a water heater work?
The thermocouple works because two different metals generate a small voltage between them when heated, a phenomenon known as the Seebeck effect. It is positioned in the pilot flame and sends a signal to the gas valve to keep it open whenever the pilot is lit. It shuts off the gas when the pilot goes out.
How does a standing pilot on a water heater work?
A water heater with a standing pilot needs a thermocouple. The thermocouple works because two different metals generate a small voltage between them when heated, a phenomenon known as the Seebeck effect. It is positioned in the pilot flame and sends a signal to the gas valve to keep it open whenever the pilot is lit.

What makes a hot water heater so interesting?
Even though they lack drama and complexity, water heaters are still pretty amazing. What makes them interesting is that they exploit the heat rising principle to deliver hot water right to your faucet with a minimum of fuss. Don’t let the simple shape shrouded in its wooly insulating blanket fool you.
What does a gas water heater look like?
A gas heater looks like an electric unit, except that it doesn’t contain the two heating elements. It has a gas burner at the bottom, with the chimney running up through the middle of the tank. HSW 2000 The water coming into your home makes a journey through a system of pipes, and it’s usually cold or cool, depending on the time of year.
How much water does a water heater hold?
Tank – The inner shell of a water heater is a heavy metal tank containing a water protective liner that holds 40 to 60 gallons (151 to 227 liters) of hot water at around 50 to 100 pounds per square inch (PSI), within the pressure range of a typical residential water system.
