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.

I cannot express how thankful I am! Jay from Goettl Air Conditioning and Plumbing replaced my water heater just when I needed it the most. It was such a stressful time when I found that my water heater was leaking. It's heartwarming to know that a company truly cares about people! Thank you so much for stepping in and helping out. I am deeply grateful!

Goettl Stepped Up

Water Heater Replacement

We hired Goettl to replace our hot water heater. Initially there were a few issues. But Goettl stepped up in a major MAJOR way. They didn’t simply repair the cartridge; they rebuilt and replaced the entire valve, even created a passageway from the closet to make easy access, just in case problems ever arise. I truly am overwhelmed with the level of service.

Respect, And It Shows

Water Heater Repair Call

We were having water heater issues. Goettl sent Joseph, who reviewed our system and gave us five different options that would meet our immediate needs. He was professional, personable and spoke to me (a female) in such a way as to not make me feel incompetent (very much appreciated). If we ever have plumbing needs in the future, Goettl will be the first we will call.

So Good, So Fast!

Water Heater Replacement

Doug was absolutely excellent. He was on time and was able to remove my old water heater, install a new bathroom faucet, install a new water heater and replaced the water filter. Within seven hours of my first call to Goettl and four hours of Doug's arrival all our problems were fixed (including a couple we weren't even aware of). Thanks Doug and thanks Goettl.

Glad I Chose Goettl

I originally went with another company for my water heater issues. But I wanted a second opinion. I called Goettl and Joseph was great. He was very friendly and very knowledgeable in his field.

True and Honest

Water Heater Repair CALL

Awoke this morning to discover no hot water in the midst of 28 degree weather. Requested assistance with Goettl plumbing and Rudy and Christopher promptly arrived to rectify the situation. They not only thawed my outdoor tankless water heater and pipes but also provided instructions on preventative measures to safeguard my unit from future occurrences.

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!
