Tankless Water Heater Installation in San Marcos, TX

Providing Reliable Tankless Water Heater Installations

If you're tired of running out of hot water in the middle of a shower or waiting for the tank to refill, consider upgrading to a tankless water heater. These energy-efficient systems provide endless hot water while helping you save money on water heating bills too!

For a reliable tankless water heater installation in the San Marcos area, look no further than Reliable Air. For more than 20 years, we’ve stayed committed to doing right by our customers. Rest assured that our highly-trained plumbers never cut corners and will get the job done right the first time around.

Benefits of Installing a Tankless Water Heater

  • Endless hot water: Unlike traditional tank water heaters that store a limited amount of hot water, tankless water heaters provide an endless supply of hot water on demand (which is why they’re often called “on-demand water heaters”). This means you won't have to worry about running out of hot water, even during peak usage times.
  • Energy efficiency: Tankless water heaters only heat water when needed. This eliminates the energy wasted on continuously heating and reheating water in a storage tank. This can result in significant energy savings and lower utility bills over time.
  • Space-saving design: Tankless water heaters are compact and wall-mounted, freeing up valuable floor space. If you have a small home, or if the location of your existing water heater has limited space, this can be a huge benefit.
  • Longer lifespan: With proper maintenance, tankless water heaters can last up to 20 years or more. Traditional heaters often need replacement after 10-15 years.
