St. Louis Tankless Water Heater Services

Reliable & On-Time Service in St. Louis

Whether you’re in the market for a new unit because you’re tired of running out of hot water in the middle of a shower, or you’re looking for a more energy-efficient alternative to a traditional system, consider installing a tankless water heater. Like the name implies, these systems do not store hot water in a tank and instead heat water on-demand as it is needed.

If you’re interested in installing one, or your current system needs repairs, turn to the experts with 17 years of experience. At Dunn Plumbing, Heating & Air Conditioning, LLC, our St. Louis tankless water heater plumbers are available 24/7 to assist you.

For a free estimate, give us a call at (314) 476-9606 today.

Why You Should Go Tankless

While a traditional water heater uses electricity to constantly warm the water it stores, a tankless unit only uses it when you turn on a faucet.

Therefore, a tankless unit provides the following advantages over a traditional one:

  • Improved energy efficiency because you are no longer needing to keep gallons of stored water hot
  • Twice as long of a lifespan
  • Continuous supply of hot water
  • Lower utility bills
  • Less required maintenance
  • A smaller design that takes up less space

We Offer Financing!

We know that sometimes replacing a water heater isn’t something you’re financially planned for. On top of our already affordable prices and free estimates, we offer financing through Green Sky.

And because we’re available around the clock and always on time, you’ll never be without hot water for long.
