Install A Water Heater

Appliance repair and replacement is technical work that requires a proper skill set and toolset, not to mention it takes time to install a new piece of hardware. Sometimes, the time for this process is doubled when you need to remove an older piece of hardware from the place and install a new one. So, is it possible to determine the time it takes to install a new appliance, such as a water heater, to be more precise?

In this post, we are delving into the details of the process of installing a water heater. We will break down the whole process into small parts and try to determine how much time it will take eventually.


No matter how prepared the technician is or your seamless you think the whole process is going to be, you can always expect speedbumps and hiccups along the way. They can certainly affect the timeline of the whole process.

There are two common exceptions that break the normal water heater installation time;

  • Removing older hardware
  • Dealing with a different type of technology

For the former, it is evident that it requires breaking and dismantling stuff before you can have the room to install the water heater. Sometimes, you need to thoroughly clean the space or deal with broken pieces of the older machine. Anyways, it prolongs the estimated installation time.

Water heaters are usually replaced after a decade. At this point, people often choose for latest tech that is hard and new for technicians to work around, or it just takes more time than usual because of all the steps involved in this process.

Now that the exceptions are out of the way, let us take a look at the breakdown of the process.

Removal Of Old Water Heater

This sounds straightforward but it eats a big chunk of time. It requires technical acumen and patience to deal with accumulated rust and dust and pull out a decade-old piece of machinery.

Safe removal means dismounting the hardware without breaking it. Following are the steps involved in this task.

Disconnecting The Power Source

Before starting the process, technicians have to make sure that the energy supply to the water heater is cut off. This is necessary to protect the technician and the heater from unexpected sparks and surges in the electricity.

Draining The Tank

An average water heater holds a couple of gallons of water. It is not possible for a team to deal with a cauldron full of water. The logical step in this direction is to drain the tank before thinking about removing the water supply lines.

Removing Water Supply Lines

Removing water supply lines ensure that no more water will enter the water heater if any faucet in the house is still running the hot mixer. If you remove the water heater without cutting the supply lines first, there are chances of puddles and mess in the place.

Removal Of Water Heater

When all of these steps are done, it is time to dismount the water heater from its place by undoing the bolts that are keeping it in its place.

If nothing goes wrong, this whole process of removing the old water heater can take from forty-five minutes to an hour.

Positioning Of New Water Heater

After the technician is done with the old unit, it is time to bring in the new unit. Make sure there is enough place to keep it steady and safe from any falling debris.


It takes time to get the unit out of the box along with the auxiliary pieces. Most of the new units come with all-in packages where you only need tools to install them. Still, take everything out of the box and place it with the water heater for connection.

Maneuvering Water Heater

Once you have connected all the necessary components with the heater, it is time to put the heater in its place. There is no need to rush because it takes care and patience to maneuver the hardware around the space.

This step of getting the new water heater to its place can take around half an hour.

System Connections

Now that the unit is in its place, it is time to make the connection. The technician will connect the power and water sources to the water heater and ensure there is no flex or play in the unions.

It takes more time to connect gas supply lines as compared to electric lines because the former needs wrenching and twisting and then close evaluation for any potential leakage.

Test & Inspection

When it is all done, the technician will run tests on it to make sure everything is where it should be, and check for missing connections or flexed and fix them if there are any.

Settings Adjustment

In the end, the system will be tuned to meet your requirements. You can do this later if you know your way around this type of appliance. Before the technician departs, make sure you ask about any maintenance routine that your water heater may require.

This process of connecting lines and checking the unit can take from forty-five minutes to an hour.

So, you are looking at two and a half to three hours if you want to have a new water heater at your place, assuming everything goes as planned. If not, it stretches the installation time.
