Replacing your new water should be quick.

Owning a home requires a lot of maintenance and upkeep. Depending on the type of maintenance necessary determines how long the maintenance or repair could take. Every project has its own timeline and necessary instructions for getting the job done. Keep in mind that some projects are bigger than others and will undoubtedly take longer to finish. Fortunately, not all projects take all day to complete. For example, swapping out your water heater should be fairly quick. How long does it take to install a water heater? Typically, a water heater will be replaced within a 2 to 3-hour timespan.

Let’s take a look below at some more information regarding this project.

What Is A Water Heater?

Water heaters have one job to do. Heat your water. As water is pushed through your plumbing you will want hot water to use. So, the water heater will take in the water and heat it up as it is pushed back into your faucets, dishwasher, clothes washer, shower, and other appliances that need hot water. In some areas, the water heater is located in the garage, and in other places, it is located in a storage closet or other location. Consequently, if you have a tankless water heater, you will likely have it hung in the laundry room or another wall that has electrical and plumbing hook-up options.

It is a great idea to replace your water heater before it goes bad.

How Long Does It Take?

Depending on the size and type of the water heater will determine how long it takes your professionally licensed master plumber to install a new one. Consider the building codes and what is needed to replace a water heater with a newer one. For the most part, installation should take between 2-3 hours to install. Let’s take a look below at what you can expect when it comes to installing a new water heater.

  • Consultation – You will want to collect at least three quotes and/or estimates from local professionally licensed master plumbers. Additionally, be sure the hot water heater you choose makes the most sense for the size of your home. Also, choose the contractor that has the most experience with these types of installations.
  • Scheduling – As soon as you realize that a new water heater is necessary, reach out to your locally licensed master plumber. Waiting too long to collect quotes or estimates can cause further damage to your plumbing.
  • Clear the Space – To make the new installation go smoothly, assist the master plumber by removing any excess furniture and clutter around the water heater. Contractors need space to work.
  • Removal of the Old One – It is necessary to drain and disconnect the old water heater from its water supply and power source to swap it out with a new one.
  • Time to Install The New One – In most cases, each old water heater will be swapped out with a more current energy-efficient model. If you have a gas line hooked up to your water heater, you will need to call on your local gas man to disconnect the old water heater and then reconnect the new water heater.

Keep in mind that installation times and the installation process will vary based on a tank water heater vs a tankless water heater. Also, electric water heaters might be less hours to replace than gas-fueled water heaters.
