When it’s time to replace your water heater in Mabank, Gun Barrel City, or around Cedar Creek Lake, you’re faced with an important decision: stick with a traditional tank water heater or upgrade to a tankless system? As your trusted East Texas plumber, Gun Barrel Plumbing breaks down everything you need to know to make the right choice for your home.
Understanding Your Options: The Basics
Traditional Tank Water Heaters
Traditional tank water heaters have been the standard for decades. These systems store and continuously heat 30-80 gallons of water in an insulated tank, keeping hot water ready for when you need it. The capacity you want depends on the size of your household and how much hot water you use, with 50-gallon units being the most common for East Texas families.
Tankless Water Heaters
Tankless water heaters, also known as demand-type or instantaneous water heaters, provide hot water only as it is needed. Instead of storing water, they heat it directly as it flows through the unit using either a gas burner or electric elements. This gives you hot water on demand without the limitations of a storage tank.
The Real Cost Comparison for East Texas Homeowners
Upfront Investment
Traditional Tank Water Heaters:
- Unit cost: $600-$2,500
- Installation: $600-$1,800 (if compatible with existing hookups)
- Total average: $1,200-$4,300
Tankless Water Heaters:
- Unit cost: $1,000-$3,000
- Installation: $1,400-$5,600 (often requires upgrades)
- Total average: $2,400-$8,600
Note: In Texas, state law requires a licensed plumber to install water heaters, which affects labor costs. The higher upfront cost of tankless systems often includes necessary upgrades to gas lines, electrical systems, or venting, especially important in East Texas, where many homes may need infrastructure updates.
Long-Term Operating Costs
Here’s where tankless units start paying for themselves. According to the U.S. Department of Energy, for homes that use 41 gallons or less of hot water daily, demand water heaters can be 24%–34% more energy efficient than conventional storage tank water heaters. They can be 8%–14% more energy efficient for homes that use a lot of hot water — around 86 gallons per day.
Monthly Energy Costs (East Texas 2025 estimates):
- Traditional tank (gas): $25-$45
- Traditional tank (electric): $35-$65
- Tankless (gas): $20-$35
- Tankless (electric): $25-$50
Based on current Texas electricity rates averaging 12-16¢ per kWh and natural gas prices. Your actual costs may vary based on usage patterns and specific utility rates in the Cedar Creek Lake area.
Lifespan and Durability: A Texas Perspective
Traditional Tank Water Heaters
Storage water heaters last 10–15 years, but East Texas conditions can affect this timeline. Our hard water around Cedar Creek Lake can accelerate sediment buildup and corrosion, potentially shortening lifespan. The large tank is also susceptible to leaks as it ages.
Tankless Water Heaters
Most tankless water heaters have a life expectancy of more than 20 years. Their design experiences less wear and tear since there’s no constant water storage that can lead to corrosion. This longer lifespan often offsets the higher initial investment.
Performance in the East Texas Climate
Cold Weather Considerations
East Texas winters, while generally mild, can pose challenges. Tankless water heaters have built-in ‘freeze protection’ so they are unlikely to freeze as long as you have electricity. Traditional tanks, with their thermal mass and insulation, are naturally more resistant to freezing but can be vulnerable at connection points.
Summer Peak Usage
During peak summer months when lake house usage increases around Cedar Creek Lake, tankless systems shine. Tankless water heaters deliver a constant supply of hot water. You don’t need to wait for a storage tank to fill up with enough hot water. This is especially valuable for vacation rental properties and busy lake houses hosting guests.
Space and Installation Considerations
Space Requirements
Traditional tanks need substantial floor space—typically a 3×3 foot area minimum. Tankless units are roughly the size of a carry-on suitcase and mount on walls, freeing up valuable space in utility rooms, garages, or closets.
Installation Complexity
For East Texas homeowners, installation requirements vary significantly:
Traditional Tank Installation:
- Straightforward replacement if upgrading like-for-like
- Existing gas lines and electrical usually sufficient
- Standard venting requirements
Tankless Installation:
- With tankless water heaters, you have to install outside vents for the intake and exhaust, and the water and gas lines need to be reworked.
- May require gas line upgrades (especially for high-BTU units)
- Electrical upgrades are often necessary for electric models
- More complex venting systems are required
According to Consumer Reports testing, tankless water heater installations can be significantly more complex than traditional tank replacements, especially when converting from one system type to another.

FAQs
Tankless installation typically takes 6-10 hours due to complexity and may require 1-2 days for complex installations, while traditional tank replacement usually takes 2-3 hours if no upgrades are needed.
Gas tankless units need electricity for ignition and controls, so they won't work during outages. Traditional gas tanks with pilot lights will continue working, making them more reliable during Texas weather emergencies.
Traditional tank systems range from $1,200-$4,300 total installed cost, while tankless systems range from $2,400-$8,600. Texas law requires licensed plumber installation, which affects labor costs.
Both systems are affected by hard water, but tankless units require more frequent maintenance (annual descaling). Water softening systems can help extend the life of either type.
Traditional tanks need about 9 square feet of floor space plus clearance. Tankless units mount on walls and require minimal space but need clearance for venting and maintenance access.
Texas utilities often offer rebates for high-efficiency water heaters. Natural gas tankless units with UEF of 0.81+ or TE of 82%+ may qualify for utility rebates. Check with your local utility company for current programs.
