TruTankless® GEN3 Tankless System

Upgrade to a smarter, stronger kind of tankless water heating. The TruTankless® GEN3 system delivers precision-controlled hot water, superior efficiency, and long-lasting performance.

What Makes TruTankless® GEN3 System Different

  1. Consistent, Endless Hot Water – Even at Peak Demand
    The TruTankless® GEN3 system uses smart sensors and proprietary software to heat water 2x faster than other tankless systems and keep water temperature steady – so every shower, load of laundry, and dish cycle stays perfectly hot from start to finish.
  2. Smarter Efficiency & Space-Saving Design
    This system only heats water when you need it, helping cut energy costs by up to 20%. Built from premium stainless steel and Incoloy® metal, it’s made to last for years (up to 20 or more) without losing performance. Thanks to the high efficiency and long life of the unit, the investment cost will usually more than pay for itself over the life of the Gen3 and its slim, wall-mounted design frees up valuable space in your garage or utility room.
  3. Tailored Flexibility & Future-Ready Setup
    Other tankless models may require you to install an extra gas line or add significant infrastructure to your electrical system. TruTankless® is built for real-world homes without the need for expensive extra construction. TruTankless models are wired to make installation simple and efficient with your existing electrical system, no extra panel breaker slot needed.
  4. Durable, Low-Maintenance Construction
    TruTankless’ custom, industry-leading heating elements only use a fraction of their full capacity, which means less strain, fewer repairs, and reliable performance – even in homes with hard water. It’s built to deliver comfort without constant upkeep. With a lifetime warranty against leaks, with the GEN3 system, your investment is safe for decades.

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.

New Tankless Water Heater

We had Goettl plumbing out for a water heater leak. We ended up replacing our old water heater with a tankless, as well as adding a water softener and filtration system. Clayton, our workman, was friendly, respectful, and knowledgeable with what would be the best for our house. Highly recommend!

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.

They Won My Business

Water Heater Replacement

We were jumping through hoops with some other companies after our hot water heater went out until we finally called Goettl. They had Joseph out to assess the problem within one hour, and then the tech Johnathan and his co-installer were here to do the repair the same day. Goettl will be our first call next time! We appreciate Joseph and the rest of the Goettl crew!
