How we get this data
Highlights
The type of water heater and the size of the unit you need are the most crucial cost factors to consider.
Most homes in Dallas use electricity as a fuel source for heat, so electric water heaters, which are more expensive than gas units, are more common.
The above-average cost of living in Dallas means labor costs will be higher than normal, but total costs are lower thanks to smaller unit sizes.
Tank-style water heaters are far more common in Dallas than tankless units, and they cost about half as much to install.
Water heater replacement costs in Dallas average $1,487, and most residents pay between $1,037 and $1,997. Many factors can affect your installation cost, but the unit type and size are the most influential ones to consider. Labor is a bit more expensive in Dallas than in most other cities due to the above-average cost of living, but household sizes are on the small side, which helps average out the pricing.
Water Heater Replacement Cost Factors
On the low end, you could pay $450 for water heater replacement in Dallas, but prices can climb as high as $6,000 in some instances. Your price will depend mostly on the type and size of the water heater you need, but fuel source and labor costs can also affect your total.
Size
Hot water heaters come in different sizes, measured by gallons (for tank-style systems) or gallons per minute (for tankless systems). The total amount of your water heater replacement cost will largely depend on the size of your new water heater, and that will depend on the size of your household.
The average household size in Dallas is 2.4 people, which means you’ll need a tank-style water heater with a capacity of 30 to 40 gallons or a tankless water heater with an output of 6 to 10 gallons per minute (GPM). You can use these averages to get a more accurate price for your water heater replacement, but you should always hire a water heater installation pro to help you determine what size you need.
The table below includes pricing for tank-style water heaters only. Most homeowners in Dallas opt for tank-style units, and tankless water heaters vary more based on specific water consumption rates, so sizing varies more widely.
| Unit Size (Gallons) | Household Size | Average Cost |
|---|---|---|
| 30 | 1–2 | $800–$2,350 |
| 40 | 2–4 | $900–$2,600 |
| 50 | 3–5 | $900–$2,800 |
| 75 | 4–6 | $1,250–$4,500 |
| 80 | 6+ | $1,450–$8,400 |
Tank vs. Tankless Water Heaters
A traditional tank-style water heater stores water in a large tank that holds anywhere from 20 to 100 gallons. If you’re like 90% of households, you have a tank hot water heater sitting on a concrete pad in a basement, laundry room, or utility room. In comparison, a tankless water heater is the size of a small suitcase, has a coil system for heating water, and is usually mounted on the wall. Your water heater installation pro can help you decide which type of water heater is best for your replacement.
| Tank-style | $650–$2,700 | Up-front cost | Operating cost |
| Tankless | $1,500–$4,200 | Running cost | Initial investment |
Types of Water Heaters
Most electric and gas water heaters cost between $550 and $1,500, but the unit type will significantly impact your cost. Around 60% of properties in Dallas use electricity as a fuel source for home heating, which means most homes won’t have existing gas connections or propane tanks for water heaters. As a result, electric water heaters are more common.
Electric water heaters are also more expensive to install, on average, and the higher cost, along with the above-average cost of living in the area, accounts for the higher water heater costs. Whole-home electric water heaters tend to be tank-style since they have a lower heat output than those that burn fossil fuels, which does help keep costs from rising well above the national average.
| Type | Average Cost |
|---|---|
| Electric | $600–$3,800 |
| Gas | $750–$2,900 |
| Propane | $750–$2,700 |
Plumber Pro Costs
Labor costs when you hire a water heater installer in Dallas average $750, which accounts for 50% of your total. This is more than you’d pay in most other cities, largely due to the above-average cost of living in the area.
You’ll need permits for any changes to home mechanicals in Dallas, so you should budget for permit fees related to water heater replacement. The City of Dallas charges permit fees based on the total cost of the work you’re planning. Given the relatively low cost of water heater replacement, you’ll just be subject to the minimum permit fee of $175.
For the most accurate price possible, you should also consider sales tax. The sales tax rate in Dallas is 8.25%, including city and state taxes, so you’ll pay an average of $122.68 in sales tax on top of your costs for materials and labor.
Safety Warning
To prevent carbon monoxide exposure from a water heater, make sure it is properly ventilated. You should also have it inspected and cleaned every year and install a carbon monoxide detector nearby. If you smell gas—which can mimic the scent of rotten eggs—evacuate immediately and call your gas company.
Do Water Heater Replacements Increase Home Value?
Replacing your water heater can positively impact your home value because buyers will have more confidence in a home with updated mechanicals. You can maximize your return on investment (ROI) by upgrading to a tankless water heater. According to a study by Zillow, this upgrade can boost home value by up to 1.2%, equating to a value increase of close to $5,800.
Texas is the second most popular state in the country for solar adoption, so you can also maximize your ROI by choosing an electric water heater if you’ve already gone solar or plan to before you sell. Buyers will likely be willing to pay more for homes with increased energy efficiency and the promise of lower utility bills.
