Tankless Water Heater Installation Anytime
Are you tired of running out of hot water halfway through a shower? Or not being able to take a bath and use the dishwasher simultaneously? A tankless water heater could be the upgrade your home needs! At Eager Plumbing, we provide professional tankless water heater installation, repair, and maintenance throughout San Antonio and the surrounding areas.
With a tankless water heater system, not only do you get hot water at your beck and call, but you also get it without the big, bulky tank, virtually no wait times, and no wasting unnecessary and costly energy. If you ask us, that’s a win-win-win-win.
What Is A Tankless Water Heater?
Tankless water heaters operate by using a gas burner or an electric element to heat water. Unlike traditional water heater systems that store and heat water in a tank, tankless water heaters heat water as it flows through the pipe to the unit, and only heat the water as you need it. That means you’ll never run out of hot water, even during busy mornings, household chores, or back-to-back showers.

The Benefits of Tankless Water Heaters
Between saving money, space, and an endless supply of hot water, there are so many benefits that come with choosing a tankless water heater installation over a traditional tank.
Unlimited Hot Water
If you have a mid-size to larger family, a tankless water heater is the clear choice. It means no more waiting for the water to warm up, timing showers, lukewarm baths, or fighting over who gets to go first! With a tankless water heater, you and your family can enjoy continuous hot water for laundry, showers, baths, and dishes whenever and as often as you need it.
Energy Efficiency
Who doesn’t love to save money? Tankless water heater units use less energy because they heat water on demand rather than storing it in a large tank, which directly impacts your monthly utility bills. In fact, according to the Department of Energy, tankless water heaters lower electricity costs by an average of 24-34% for homes using less than 41 gallons of water a day. That equates to about $100 in savings in a year! For higher energy-consuming homes, they still offer a savings of 8-14%.
Longer Lifespan
Traditional water heater systems generally provide 8 to 12 years of reliable hot water, whereas tankless water heaters typically deliver 15 to 20 years with proper care and routine maintenance. That’s nearly double the lifespan and without all the hassle!
Space-Efficient Design
One of the most convenient aspects of a tankless water heater installation is the space-saving design. These compact systems are typically mounted on walls, freeing up valuable square footage in your home or garage. If you have limited wall space or walls that can’t support a mounted unit, tankless water heaters can be installed on the floor on custom-built, specialized metal racks or even under sinks, tight utility spaces, or closets.
Cleaner Water
San Antonio is known for having hard water, which simply means water that has higher concentrations of dissolved minerals like magnesium and calcium. Hard water isn’t just hard on your appliances and pipes; it can also dry out your skin and hair, make cleaning more difficult, and wear out your clothes and linens faster.
Tankless water heaters deliver cleaner, fresher water than their traditional tank system counterparts. Because they don’t store water, they avoid accumulating rust, silt, sediment, and bacteria that commonly build up in conventional tanks. Even better, tankless water heaters only need occasional descaling to maintain pure, high-quality water, making them the optimal choice.
Better For The Environment
Because of the increased efficiency offered by tankless water heaters, having one directly affects and reduces greenhouse gas emissions. If one of your goals is to lessen your household’s carbon footprint, installing a tankless water heater is a great way to achieve it.
Federal Tax Credits For Gas Tankless Water Heaters
Texans who install a qualified high-efficiency gas tankless water heater can claim a tax credit under the Inflation Reduction Act of 2022, section (25C). This credit is typically worth up to $600 (about 30% of costs) and is applicable through 2032. For even more potential savings, make sure to check your local Texas gas companies for additional rebates.
