Tankless Water Heater Cost Factors 

Overall, the size and type of tankless water heater chosen will determine the cost for this project at your home. When you contact a local water heater pro in Tampa, FL, they'll create a quote based on your water usage needs, home size, and budget.  

Single-Point Tankless Water Heater vs. Whole-House System

You can choose between single-point and whole-house tankless water heater systems. Some homeowners mix and match, installing a whole-house unit to handle the primary heating duties and placing a single-point system in an additional bathroom. This allows multiple people to shower at once.

Fuel Type

The type of hot water heater you choose plays a big role in how much you’ll spend. There are several types of tankless heaters to consider based on the energy source used in your home:

Size

Another primary cost factor is the size of the water heater. Larger heaters service a higher volume of water than smaller heaters, so count on increased costs. The amount of energy the heater can handle is one indicator of size. For tankless gas water heaters, the amount of energy they can handle is measured in British thermal units (BTU); electric water heaters use kilowatts (kW). When comparing gas, electric and solar systems, a better measure for comparison is gallons per minute (GPM).

• Gas water heaters: Smaller water heaters of 120 to 140 BTUs cost $500 to $1,200, which is enough for a one- or two-bedroom home. Larger water heaters of 180 to 200 BTUs or more cost $900 to $2,200, and these appliances handle enough volume to service a home with five or more people. Gas water heaters have an average flow rate of up to 5 GPM.

• Electric water heaters: Smaller water heaters of 5 to 8 kWs cost $100 to $250, though this is just enough for a one-bedroom apartment or small home. Keep in mind that electric water heaters only have a flow rate of up to 2 GPM. Mid-sized electric water heaters of 10 to 24 kWs cost $210 to $630 and can efficiently service a two-bedroom home. Large heaters of 27 to 36 kWs cost $420 to $800 and can handle enough volume for an expansive home. 

• Solar water heaters: When solar power is used as a backup for an electric tankless water heater, sizing is the same. However, Tampa homeowners opting for traditional solar water heating systems can choose units with smaller collectors, typically around 40 to 60 square feet, costing between $1,500 and $2,000, or larger systems with collectors around 80 square feet, costing between $2,100 and $2,500.

Tankless Water Heater Pro Costs

A licensed plumber is needed to install a tankless water heater in Tampa. If you're unsure about your usage needs, a plumber will be able to advise you on the size of water heater that's ideal for your household. In addition, they can provide tips on how to flush a tankless water heater and maintain all parts.  

Labor Costs

Hourly rates for plumbers in Tampa range from $45 to $75 on average. If you're hiring a licensed master plumber for a water tank installation involving gas lines, the rate may be as high as $50 to $90 per hour. All Tampa plumbers must have a Florida plumbing license in order to install water heaters. When you contact a Tampa plumber who installs tankless water heaters, they will provide a custom quote based on the model of water heater you choose and the overall scope of the project.  

Permits

A permit is required when installing or replacing a water heater of any kind in Tampa to ensure that the project complies with Florida building codes. This also applies to in-kind replacements using identical water heaters. Permits for water heaters in Tampa cost $120. If your plumber needs to pull a permit for natural gas piping involved with the project, the individual permit fee for that portion is $162.

Accessibility

If the desired location of the new tankless system is difficult to access or narrow and harder to work in, this can raise the labor costs to up to 10% to 15% of your project total. Prices will vary based on the home and setup.

Current Heating System Removal

Removing an existing hot water heating system can cost $500 or more, depending on the unit's size and accessibility, as well as the contractor's hourly rate. When looking for an installation quote, make sure the quote includes the removal and disposal of your current water heater.

Does Installing a Tankless Water Heater Increase Home Value?

In general, a tankless water heater increases home value by roughly 1.2%. For Tampa homeowners, upgrading to an energy-efficient water heater can also reduce monthly utility bills.
