Benefits of Tankless Water Heaters
The benefits of installing a tankless water heater include:
Endless Hot Water: Tankless means limitless. Being able to supply as much hot water as needed is among the biggest differences tankless hot water system owners notice when switching. Pay attention to your water usage if you do switch, it’s easy to get carried away with comfort.
Smaller Footprint: Tankless water heaters save valuable space inside or outside your home. Units range in size from a small backpack to medium-sized suitcase, and are typically wall mounted.
Energy Efficiency: By eliminating standby heat loss, tankless water heaters are more energy efficient, resulting in an average savings of 30% on your household energy use.
Increased Lifespan: Traditional water heaters usually last about 6 to 10 years, while a tankless hot water heaters typically last up to 20 years or more when well maintained. Upkeep is key to seeing the most out of this benefit.
Lower Risk of Leaking and Water Damage: A rupture, seal failure or failed pressure gage on a water heater tank can result in dozens of gallons of spilled water. Tankless water heaters store no water in reserve, vastly reducing the risk of water damage, sediment buildup and corrosion.
From tankless water heater installation to maintenance to repair, Goettl San Antonio has got you covered. So give us a call today, and experience the Goettl difference.

No Corners Cut Here
New Tankless Water Heater
We used Goettl to replace our existing tank water heater. We went with a recirculating tankless water heater. Goettl worked with our schedule, and even though it was a late afternoon decision, Goettl was able to send two well qualified technicians at our house that very evening. Gabriel and Brendan were courteous, professional and knowledgeable. Their upbeat and spirited attitude made them a pleasure to meet and have in our home. Even though it was pushing midnight by the time installation was wrapping up, Gabriel and Brendan did not seem to rush or cut corners.
