Tankless Water Heater Cost Factors 

The cost to install a tankless water heater in Raleigh, NC, will depend on your household's hot water needs. A local plumbing professional will consider the size of your household, your usage patterns, and your budget when making recommendations. Additionally, a knowledgeable local plumber will help you understand everything from tankless water heater pros and cons to how to flush a tankless water heater properly.

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.

System TypeCapacity (gallons per minute)Average Cost
Single-Point System1–2 GPM$600–$1,700
Whole-House System3–10 GPM$1,800–$3,900

Fuel Type

Wondering how much you can save (or spend) on a tankless water heater? One of the best ways to calculate your expenses is by the type of hot water heater you choose. There are four types of tankless heaters to consider:

Fuel TypeAverage CostProsCons
Natural gas$1,500–$3,500Reliable outputMore expensive installation
Electric$600–$1,880Simpler installationNot as consistent
Solar$2,000–$3,900Energy efficiency, ideal for Raleigh’s climateComplex installation

Size

A 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 the British thermal unit (BTU); electric water heaters use kilowatts (kW). When comparing gas, electric, and solar tankless water heater systems, another measure of size is capacity. 

Gallons per Minute (GPM)UsageAverage Cost
1–2 GPMPoint of use$600–$1,700
2–4 GPMWhole house (small)$1,800–$2,200
5–7Whole house (medium)$2,300–$3,500
8–10Whole house (large)$3,500–$3,900
  • Gas Water Heaters: Smaller water heaters of 120–140 BTUs cost $500 to $1,200, which is enough for a one- or two-bedroom home. Larger water heaters of 180–200 BTUs or more cost $900 to $2,200, and these appliances handle enough volume to service a home of five or more people. Gas water heaters have an average flow rate of up to 5 gallons per minute (GPM).

  • Electric Water Heaters: Smaller water heaters of 5–8 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 10–24 kWs cost $210 to $630 and can efficiently service a two-bedroom home. Large heaters of 27–36 kWs cost $420 to $800 and can handle enough volume for an expansive home. 

  • Solar Water Heaters: If you're adding solar power to take advantage of Raleigh's sunny climate as a backup option for your electric unit, sizing for electric water heaters applies. In addition, solar water heaters are available in 80-gallon to 120-gallon capacities with average pricing ranging from $2,900 to $3,900 in Raleigh.

Labor Costs

In Raleigh, handymen cannot provide plumbing installations. That means you'll need to hire a licensed and registered plumber for tankless water heater installation in Raleigh. On average, Raleigh plumbers charge between $65 and $90 per hour for this type of job.

Permits

While you do not need to submit plans to the city to install or replace a water heater in Raleigh, a permit is still needed. A flat fee of $75 will be added to the project cost for this permit.

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?

Yes, it's estimated that a tankless water heater can increase a home's value by as much as 1.2%. Raleigh homeowners who upgrade to newer, more efficient tankless water heaters can also significantly reduce monthly energy bills. The greatest ROI comes from upgrading to an Energy Star tankless water heater that has the appropriate capacity for your household.
