How Much Does It Cost to Install a Water Heater in Tucson?

In the market for a new water heater? The cost to install a new water heater in Tucson can range anywhere from $660 to $1,850+.

If this seems like a broad range, it’s because the cost of installation depends on the following factors:

  • The type of water heater (tank vs tankless)
  • The water heater’s heating capacity
  • The fuel type the heater uses
  • The contractor you hire for the installation

Let’s review how each of these factors can impact the overall cost of your water heater installation.

Cost Factor #1: Type of water heater

The cost factor that will impact your cost of installation the most is the type of water heater you choose.

Let’s look at how the two types compare in price:

  • The average cost to install a tankless water heater is $959-$1,950
  • The average cost to install a tank water heater is $875-$1,490

Tankless water heaters generally cost more than tank water heaters. Tankless water heaters are more expensive because they are more energy-efficient. They can help you save on energy consumption because they only heat water on an as-needed basis.

Since tankless water heaters consume less energy, they also can last up to 20 years, which means less frequent replacement costs for you. Overall, the long-term cost benefits of a tankless water heater could help you recuperate the initial investment price.

If you have any questions about what type of water heater you should get, consult with a plumber. They can help you determine which option is best for you based on your needs and budget.

Cost Factor #2: Heating capacity

The heating capacity of a water heater determines how much hot water it can provide. A higher heating capacity means the water heater will be more expensive.

For a tank water heater, heating capacity is measured by its tank size and first hour rating.

  • The tank size is merely how much hot water (in gallons) the tank holds when full. Average residential tank size ranges from 50-80 gallons.
  • The first hour rating measures how many gallons of hot water the tank can provide for a straight hour, starting with a full tank.

For a tankless water heater, heating capacity is measured by its flow rate.

  • Flow rate is the amount of hot water (in gallons) the unit can produce per minute, also known as gpm. A high flow rate lets you use multiple water appliances at the same time and not run out of hot water. If you want to be able to run your kitchen sink (0.80 gpm) and shower (3 gpm) at the same time, you add up their flow rates, which means your tankless water heater needs a flow rate of at least 3.80 gpm.

To determine the heating capacity right for your hot water needs, contact the Advantage Air Mechanical team to help find the best tank or tankless water heater for you.

Cost Factor #3: Fuel type

Natural gas water heaters generally cost more to install than electric water heaters.

However, when you invest in a gas unit, it’ll cost less to operate on a monthly basis, and the savings on your energy bills may cover the initial cost of installation.

If you have access to natural gas, the most cost-effective option is to go with a gas water heater because of the low monthly usage costs. If you don’t have access to natural gas, you’ll have to add gas lines and venting, which could add an additional $600-$1,500 to your installation price.

So, if you have an electric water heater already and no natural gas, the most cost-effective option will probably be to stick with an electric water heater going forward.

Cost Factor #4: Contractor you hire

Experienced, high-quality plumbers will usually charge more for their work, but they can save you money by taking the time to make sure your water heater is correctly installed.

You’ll want to be wary of plumbers who offer dirt-cheap installation prices compared to other plumbers in your area. Lower-quality plumbers might rush the installation, which could result in expensive repairs and higher energy bills.

To look for a high-quality plumber in Tucson that will provide you with a good experience, look for:

  • A plumber that is licensed and insured in the state of Arizona
  • A plumber that has been in business for 10+ years
  • A plumber that offers transparent, upfront estimates in writing so you’re never surprised by the final bill
  • A plumber that has good customer reviews on sites like Google and Facebook
  • A local plumber that supports the community and gives back
