Tankless Water Heaters

Tankless Water Heaters

Imagine never running out of hot water, even if the dishwasher, washing machine, and shower are running at the same time. Tankless water heaters provide on-demand hot water while reducing your energy bills by up to 40%.

Merritt Plumbing specializes in the installation and maintenance of high-performance tankless systems (Navien, Rinnai). We handle everything from the gas line upgrade to the venting.

Why Go Tankless?

  • Endless Supply: Hot water that never runs out.
  • Space Saving: Wall-mounted units free up valuable floor space in your garage or closet.
  • Longevity: Tankless units last 20+ years (twice as long as traditional tanks).
  • Efficiency: You only pay to heat the water you use, not a standby tank.

Expert Installation: Converting to tankless isn’t a simple swap. It requires precise calculation of gas load, water flow, and venting requirements. Trust the veteran-led team at Merritt to get the engineering right the first time.

The Merritt Difference: We provide a full assessment of your home’s infrastructure before we quote, ensuring no surprise costs. Plus, our Merritt VIP Club members get annual descaling included to protect their investment!
