Precision Tankless Water Heater Replacement

Upgrade to Endless Hot Water and Superior Energy Efficiency

Are you tired of running out of hot water halfway through a shower? Is your bulky, old water tank taking up valuable space in your Michigan basement? At Riviance HVAC, we specialize in professional tankless water heater replacement and upgrades across Ann Arbor, Ypsilanti, Canton, Saline, and the surrounding areas.

Transitioning to a tankless (on-demand) system is a significant home improvement that offers unparalleled comfort and long-term energy savings. However, a tankless unit requires precise installation—including specialized venting and gas line configurations—that only a certified professional should handle.

Why Upgrade to a Tankless System?

Unlike traditional tanks that constantly heat and reheat 40–50 gallons of water, a tankless system only heats water the moment you turn on a tap.

  • Endless Hot Water: Never worry about being the last one in the shower again. Tankless units provide a continuous flow of hot water for as long as you need it.

  • Space-Saving Design: About the size of a small suitcase, tankless units mount to the wall, freeing up significant floor space in your utility room or basement.

  • Double the Lifespan: While traditional tanks usually last 8–12 years, a well-maintained tankless unit can last 20 years or more.

  • Lower Energy Bills: Because they don’t suffer from “standby heat loss,” tankless water heaters are up to 34% more energy-efficient than traditional tanks.

When to Replace Your Current System with Tankless

If you are facing any of the following situations in your Southeast Michigan home, a tankless upgrade might be the perfect solution:

  1. Your Old Tank is Failing: If your current tank is leaking or over 10 years old, it’s the ideal time to invest in a modern upgrade rather than another “old-tech” tank.

  2. Home Remodeling: If you are adding a bathroom or a high-flow showerhead, your existing tank may no longer be able to keep up with the demand.

  3. Growing Family: More kids means more laundry and more showers. A tankless system grows with your needs.

  4. Eco-Conscious Living: If you want to reduce your home’s carbon footprint and gas consumption, tankless is the gold standard for water heating.

The Riviance Tankless Installation Advantage

Replacing a tank with a tankless unit is a complex mechanical task. Our team ensures a seamless transition by handling the critical technical details:

  • Gas Line Upgrades: Tankless units require more BTUs than standard tanks to heat water instantly. We ensure your gas lines are sized correctly for safe operation.

  • Advanced Venting: We install specialized concentric or PVC venting systems to ensure combustion gases are safely moved out of your Michigan home.

  • Precision Sizing: We calculate your “peak demand” to ensure the unit we install can handle your dishwasher, shower, and laundry running simultaneously.

  • Condensing Technology: We offer high-efficiency “condensing” models (like those from Navien) that extract even more heat from the exhaust for maximum savings.

Why Choose Riviance HVAC for Your Upgrade?

  • Certified Navien & Rinnai Experts: We are trained in the specific installation protocols for the industry’s leading tankless brands.

  • Local Hard Water Knowledge: We understand Michigan’s water chemistry and can install integrated scale-prevention systems to protect your new unit.

  • Transparent Project Estimates: We provide clear, fixed-price quotes that cover everything from the unit itself to the necessary plumbing and gas line modifications.
