Tankless Water Heater Cost Factors
A wide range of factors can influence the cost of a tankless water heater in Portland, Oregon. Tankless water heaters cost about 10% more in Portland compared to the national average, but these prices depend on factors such as the type of system, the fuel source for the system, and the size of the system.
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.
| Comparison | Single-Point | Whole-House System |
|---|---|---|
| Cost | $100–$325 | $500–$1,650 |
| Hot water distribution | Water supplied to a single fixture (such as a faucet or showerhead) | Water supplied throughout the entire house |
| Efficiency | Short distance for the water to travel for quick access | Longer distance from central source |
| Heating power | 0.5–2 gallons per minute | 5–10 gallons per minute |
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 | Cost | Pros | Cons |
|---|---|---|---|
| Electricity | $500–$1,650 | Most affordable option, easiest to install, greater energy efficiency than gas | Performance suffers during high-demand scenarios |
| Natural gas | $1,100–$1,650 | Performance unaffected during in-demand scenarios, more energy-efficient than traditional tank systems | Costs more than electric |
| Propane | $1,100–$1,650 | Performance unaffected during in-demand scenarios, more energy-efficient than traditional tank systems | Costs more than electric |
| Solar | $1,975–$6,600 | Greatest energy savings over time, low maintenance | Steeper up-front costs, Portland has notably fewer-than-average sunny days |
Size
A primary cost factor is the size of the tankless 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 (BTUs). Electric water heaters use kilowatts (kW).
| Type of Water Heater | Cost |
|---|---|
| Gas (small) | $550–$1,325 |
| Gas (large) | $1,000–$2,425 |
| Electric (small) | $100–$275 |
| Electric (mid-sized) | $225–$700 |
| Electric (large) | $450–$875 |
| Solar | $1,975–$6,600 (varies by performance) |
Gas Water Heaters: Smaller water heaters of 120–140 BTUs cost $550 to $1,325, which is enough for a one- or two-bedroom home. Larger water heaters of 180–200 BTUs or more cost $1,000 to $2,425, 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 $275, 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 $225 to $700 and can efficiently service a two-bedroom home. Large heaters of 27–36 kWs cost $450 to $875 and can handle enough volume for an expansive home.
Solar Water Heaters: In Portland, tankless solar water heater costs go from $1,975 to $6,600, depending on performance. Rather than measure performance in gallons per minute, we look at the solar fraction—that is, the ratio of hot water provided by the solar-powered tankless water heater to the total amount of hot water needed. In addition to the federal tax credit available for solar water heaters, Portland residents can take advantage of the $700 instant discount through the Energy Trust of Oregon’s incentive on select models.
Tankless Water Heater Pro Costs
Homeowners should not attempt to install a tankless water heater themselves since the work can be challenging. In fact, most water heater warranties require professional installation. That means you’ll need to consider the fee for a Portland water heater installer when calculating the overall cost of a tankless water heater in Oregon.
Labor Costs
Professional labor costs account for a little less than half of the overall cost to install a tankless water heater in Portland. Budget between $650 and $2,025 for a local plumber. You can get quotes from at least three Portland-area contractors to compare prices and find the most cost-efficient option.
Permits
Installing a tankless water heater does require a plumbing permit in Portland. In the City of Portland proper, a plumbing permit costs $60 for installing a water heater.
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?
A recent report from Zillow found that a tankless water heater boosts your home’s value by 1.2% on average.
Assume your home is worth $550,000 (the current median home price). That means a tankless water heater could add $6,600 of value to your home, even though it only costs an average of $2,800 to install a tankless water heater in Portland. That means a tankless water heater pays for itself—and adds several thousand dollars to your pocket, theoretically.
Regardless of how much a tankless water heater boosts your home’s value, it’s well worth the investment for the energy savings alone. The Department of Energy estimates homeowners save between 8% and 34% on utility bills after installing a tankless water heater. Installing a solar tankless water heater could yield even greater energy savings.
