How Long Does It Take to Install a Water Heater?

Are you wondering how long it takes to install a water heater? Installing a new hot water heater is not like other appliances in your home. It’s not typical, so plug it in, and you are good to go. You need to connect the plumbing and electrical components. Improper water heater installation can result in significant damage, so you need to be very careful. 

Whether you have an emergency and need your water heater replaced, knowing how much time you need to install a water heater is crucial. In this post, our professional HVAC technicians share valuable insights on water heater installation.

How to Install a Water Heater

In Denver, almost every home has a water heater installed. If you’re experiencing water heater problems, you most likely want the issue fixed as soon as possible. However, keep in mind that the procedure may differ slightly between hot water heaters. At Flawless Air Mechanical, we recommend having a professional install a water heater for you to ensure a safe and proper installation.

According to the U.S. Department of Energy, common water heater units include conventional storage water heaters and tankless units or on-demand water heaters, with a variety of energy-efficient types available. A typical tank model lasts 10 to 12 years on average, while water heaters without tanks have a minimum lifespan of 20 years.

Here’s what you can expect from water heater installation:

Assessment

A professional installer will first assess your home's needs, including the size of the water heater required and any necessary modifications to accommodate it.

Selection of Unit

Depending on your needs and preferences, you'll choose the type of water heater, whether it's traditional tank-style, tankless, heat pump, or solar-powered.

Preparation

The installation team will prepare the area where the water heater will be placed. This might involve clearing space, adjusting plumbing connections, or making other modifications.

Installation

The new water heater will be installed according to manufacturer specifications and local building codes. This includes connecting it to the water supply, gas or electricity (if applicable), and any necessary ventilation systems.

Testing

Once installed, the installer will test the water heater to ensure it's functioning correctly. They'll check for leaks, proper temperature settings, and adequate water flow.

Safety Checks

Before leaving, the installer will perform safety checks to ensure there are no gas leaks (if it's a gas-powered unit), proper ventilation, and secure connections.

Cleanup

Any debris or packaging materials from the installation will be cleaned up and removed from your property.

Instruction

The installer should provide you with instructions on how to operate and maintain your new water heater. They'll also answer any questions you might have about its operation.

How Long Does It Take to Install a Water Heater

When you install a water heater, it typically takes only two to four hours. On the other hand, if there isn't enough room, complex quick water heater installations could take longer. It's common for larger-capacity heaters to require less time to install than smaller ones. 

The average installation of a new gas-powered water heater can take two to eight hours since gas piping and fittings need to be installed in addition to the plumbing for the water supply. It also takes time to remove the old water heater if a new one is being installed. Hiring a trustworthy professional is important because water heater service providers can complete the task quickly and efficiently. 

Factors Affecting Water Heater Installation

Variables like the type of water heater—be it tankless, traditional tank-style, or another variation—can influence the timeline. Location also plays a role; accessibility affects the ease of installation. The complexity of the installation itself, contingent on factors like the size of the heater and plumbing configuration, contributes to the overall duration. Consulting with professionals provides a more precise estimate.

Here are a few variables that affect the length of time to install a water heater

Type of Water Heater

Different types of water heaters require varying installation times. For example, installing a tankless water heater might take longer due to additional plumbing and electrical work, while a traditional tank-style heater might be quicker.

Location

The location of the water heater within your home can impact installation time. If it's in a tight or difficult-to-access space, the installation process may take longer as the installer navigates the area and makes any necessary adjustments.

Existing Infrastructure

The condition of your home's existing plumbing and electrical infrastructure can affect installation time. If upgrades or repairs are needed to accommodate the new water heater, this can add to the overall installation timeline.

Permitting and Codes

Obtaining necessary permits and ensuring compliance with local building codes can also impact installation time. Delays in obtaining permits or addressing code requirements may prolong the installation process.

Complexity of Installation

Some installations may be more complex than others, depending on factors such as the size of the water heater, the configuration of your home's plumbing system, and any additional features or accessories being installed alongside the water heater.
