How each works
A tank water heater stores and keeps 40 to 80 gallons of water hot. A tankless water heater heats water only as it flows, so it never runs out but has a limit on how many fixtures it can supply at once.
Upfront cost
Tank heaters cost less to buy and install. Tankless units cost more upfront, especially if your gas line or venting needs upgrades.
Hot water supply
Tankless provides continuous hot water, ideal for larger families. A tank provides a fixed supply; once it is used, you wait for recovery.
Space and lifespan
Tankless units mount on a wall and free up space. They often last longer than tanks with proper maintenance.
Hard water considerations
Texas hard water causes scale in both types. Tankless units need annual descaling; tanks need regular flushing. A water softener helps either system last longer.
Our recommendation
If your tank is failing and budget matters, a new tank is a solid choice. If you want endless hot water and plan to stay in your home, tankless is often worth it. Learn more about tank water heater installation and tankless water heater installation.
