How Long Does It Take To Install A 40 Gallon Hot Water Heater
In general, replacing a 40-gallon water heater is faster and more practical than completing a new installation. A professional plumber can install a 40-gallon water heater within two to six hours, barring any mishaps and other untoward incidents.
Removing the old gas water heater should take about 45 minutes to an hour, while positioning and securing the replacement unit can take 30 minutes. Connecting the system to the power source and other elements can last 45 to 60 minutes.
However, gas water heaters with tanks require adequate ventilation and exhaust management. These requirements can extend the overall installation by at least another hour. If the water heater is in a tight space, such as a closet or attic, one can expect the labor time to increase.
How Does It Work
Conventional water heaters come with a tank where you can store your hot water- ready to be used for your daily household activities.
First, cold water enters the 40 gal water heater tank through a cold water supply tube. The tank itself is made of steel to protect both its exterior and interior. This material also enables the water to heat up quickly.
Next, as the cold-water settles, the tanks bottom is slowly being heated up by the gas burner.
A gas regulator assembly controls and determines how hot the gas burner is. This regulator usually comes with a thermostat to measure the temperature and turns the burner on/off once the water reaches a specific temperature.
Once the water grows warm enough, it rises and passes through a hot water discharge pipe to provide hot water whenever needed.
The steam, gases, and other byproducts of the heating process leave the tank, go to an exhaust flute, and exit the tank via a vent pipe or, sometimes, a chimney.
