Tankless Water Heater Cost Factors
When choosing between tankless water heater vs tank, Atlanta, GA homeowners may get vastly different quotes based on whether they select a gas, electric, or solar tankless water heater. Altana's nearly 220 days of sunshine per year can make a solar tankless water heater a more viable option compared to cities with reduced sunlight throughout the year. While solar tankless water heaters are more expensive to install initially, the lifetime energy savings compared to other options can be substantial. In fact, the Department of Energy states that homeowners can reduce water heating costs by as much as 80%.
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 Type | Capacity | Average Cost |
|---|---|---|
| Single-Point System | 1–2 GPM | $560–$900 |
| Whole-House System | 3–10 GPM | $800–$4,300 |
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 Type | Average Cost Range | Pros | Cons |
|---|---|---|---|
| Natural gas | $1,000–$3,400 | Consistent water temperatures | Complex, more expensive installation |
| Electric | $550–$2,000 | Energy-efficient | Less consistent water temperature |
| Solar | $1,900–$4,450 | Long-term energy savings of 50%–80% | Higher upfront cost |
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, a good measure to use is gallons per minute (GPM).
| Gallons per minute | Usage | Average Cost |
|---|---|---|
| 1–2 GPM | Point of use | $560–$900 |
| 2–4 GPM | Whole house (small) | $800–$1,350 |
| 5–7 GPM | Whole house (medium) | $1,300–$2,200 |
| 8–10 GPM | Whole house (large) | $2,700–$4,300 |
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: A solar tankless water heater that's ideal for a household with three to four people costs an average of $1,900 in Atlanta when installed with a 60-foot collector. Expanding to solar tankless system with an 80-foot collector might cost closer to $3,000 to $4,200.
Tankless Water Heater Pro Costs
Plumbers offering tankless water heater installation in Atlanta, GA will customize quotes by assessing the time and expertise needed to complete a project. Gas water tank installations tend to represent the highest price range due to the added risk for gas leaks and carbon monoxide poisoning.
Labor Costs
In Atlanta, the average hourly rate for a plumber is between $65 and $109. However, homeowners generally need to hire master plumbers commanding rates closer to $85 to $189 per hour for a complex project like a tankless water heater installation that involves gas lines.
The higher cost per hour is reflective of the fact that all plumbers must be licensed by the Georgia Construction Industry Licensing Board with a Journeyman Plumber License, Master Plumber License (Class I), or Master Plumber License (Class II) in order to complete plumbing work. In addition to the fees and time involved with training for licensing, all plumbers must pay license renewal fees totaling $100 to $200 every two years.
Permits
While not universal across all of Fulton County, Atlanta does require permits for installing, repairing, or replacing any type of water heater. The cost for a permit to remove or replace an existing hot water tank for a one-family to two-family residence in Atlanta is $50. All other general plumbing permits that may be necessary for this project range from $150 to $175.
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?
When considering tankless water heater pros and cons, there’s one standout pro. Tankless water heaters allow homeowners to cut utility bills by 10% to 80% annually. Atlanta's sunnier climate means that homeowners can significantly reduce energy costs by going with a solar tankless water heater. However, gas and electric options can still produce a return on investment of 70% or more.
