What is the Average Cost to Install a Gas Water Heater?

The cost to install gas water heater systems usually ranges somewhere between $1,500 and $4,000. This figure reflects a national average that considers everything from labor to permits. To understand the final price, here’s a closer look at what to expect: 

  • Location: Prices may vary by region due to labor costs and local regulations.
  • Size of the Unit: Larger water heaters will usually cost more to install than smaller units.
  • Complexity of Installation: Jobs that require additional labor or modifications can push the cost to the higher end of the range.

What Impacts Gas Water Heater Installation Costs?

Installing a gas water heater isn’t always straightforward, and there are several things that can impact the cost, including:

Type and Size of Your Water Heater

Your gas water heater’s size and model will significantly impact the installation costs. Choosing a traditional gas tank unit is usually less expensive to install than tankless models. If you need a larger capacity tank, you also need to factor in the additional cost of the unit plus the increased labor required to install it.

Overall Labor Costs

The manual labor involved is a major part of the gas water heater installation cost. Your water heater team may charge different rates depending on the complexity of the job, the materials used, and the type of unit you choose. 

Permit and Inspection Fees

Depending on your area, installing your new gas water heater may require permits to ensure it complies with the latest safety standards and building codes. The permit fees will vary but are usually included in the total installation cost.

Materials and Accessories

Your home or business may need additional materials like venting pipes, expansion tanks, or gas line extensions. All of these things can increase the installation cost for gas water heater systems, but they are all necessary to keep your property safe.

Old Water Heater Removal

When you replace an existing unit, removing and disposing of it will also add to your installation costs. Give the team at Trailblazer Plumbing a call to ask for an estimate and quote on how much it costs to remove your old water heater.

How Does Installation Affect the Price of a Water Heater?

The complexity of your water heater installation will also impact the price of your new water heater. Here are some other factors to consider:

Replacing a Similar Unit vs. New Installation

Your installation is usually straightforward if you replace an existing gas water heater with a similar unit. But if you’re switching from an electric to a gas model, you’ll need a more complex installation that increases the overall labor costs.

Accessibility of the Installation Area

When your water heater is in an easy-to-access area, you’ll enjoy lower installation costs. But if it’s in a difficult area to reach, like a basement or crawlspace, the job will take more time and effort and raise the overall price. 

Are There Hidden Costs in Gas Water Heater Installation?

It’s always important to consider whether or not unexpected expenses will pop up during installation, which adds to the cost of the gas water heater installation. These hidden costs may include:

  • Additional labor: If your water heater installation team finds damaged pipes or outdated venting systems, some extra labor and materials may be required to complete the job.
  • Materials: Some water heater installations may require unexpected venting or plumbing fittings.

Is a Gas Water Heater More Expensive to Install Than an Electric Water Heater?

Yes. On average, the installation costs for a gas water heater is going to be somewhat higher than newer electric models. Traditional gas models often require modifications to the gas line and additional work to ensure proper venting. However, gas water heaters are also usually more energy-efficient and lead to longer-term savings on your utility bills.

Are There Any Rebates or Tax Incentives for Installing a Gas Water Heater?

Sometimes local utilities and government programs will offer tax incentives, rebates, or other promotions just for making the switch to more energy-efficient gas water heaters. They lower your installation costs and make them a popular option for homeowners. Ask the team at Trailblazer Plumbing about the latest incentives, or check your local utility company and government websites for energy-saving programs.

What Maintenance Costs Should You Expect After Installation?

Once you get your gas water heater installation installed, you’ll still need routine maintenance to ensure its longevity and keep it in good, working order. Call Trailblazer Plumbing for regular upkeep, which includes flushing out the tank once or twice a year to remove sediment buildup. Regular water heater maintenance expands the lifespan of your unit and stays ahead of costly repairs. Perhaps just as importantly, you enjoy reliable hot water for more comfort and peace of mind.
