Upgrade to a Rinnai Tankless Water Heater

Don’t wait until your water heater fails to make the switch to a Rinnai tankless water heater. Many homeowners upgrade because their traditional water heaters can’t keep up with hot water demands, heat water efficiently, or distribute it evenly. A Rinnai tankless water heater provides:

  • Endless Hot Water: On-demand heating ensures you never run out, even during peak usage.
  • Compact Design: Save space with a sleek, wall-mounted unit.
  • Durability: Lasts up to twice as long as traditional water heaters.
  • Energy Efficiency: Reduce your energy bills with advanced technology.
  • Smart Integration: Compatible with smart home systems for added convenience.

As a locally owned and operated company, we recommend Rinnai for its proven reliability and innovation. At Full Stack Plumbing & Well, we’re proud to be part of the Rinnai ACE Pro Network, a certification that underscores our expertise and commitment to quality installation and customer satisfaction.

From scheduling to installation the service was more than acceptable. However I was NOT informed at time of scheduling that the company had changed to flat pricing instead of hourly. Cost of installing a simple kitchen faucet with no connection changes needed. Time of installation was less than an hour for over 300 dollars. Ridiculous

They got the job done, but should know better than to come in and out with wet shoes. Should have done better cleaning up afterwards, for the amount of money it cost..

Jacob did a heroic job! He put in a huge physical effort and tried many ways to make something work. He was here a long time.

JJ helped and made the outdoor water faucet work. Also he did a preliminary survey of the house plumbing and provided a plan. He was able to come early and knocked everything out for the better.

I recently had my well pump replaced, but I was left with a mountain of problems afterwards. The mud from the well was never flushed out of the system but was forced into my plumbing which caused a bunch of trouble. All this could have been eliminated by flushing the lines before connecting them to the pressure tank under the house. This mud clogged up toilet fill valves. Faucet aerators tub spout aerators, the grit in the water caused damage to cartridges for the sinks. Shut offs. Stopped up the screen on the Rinanni water heater. Kenneth and his partner did a wonderful job, maintaining neatness and professionalism in my home.Full Stack Plumbing has always had my business!

Called first thing Monday for a clogged kitchen sink I couldn’t resolve myself the day before.Woman on the phone was kind, professional - asked a couple questions, took notes, scheduled the appointment for that same morning and mentioned they would text when on the way.2 hours later received the text. 10 min later they arrived. 2 hours later we were back up and running. Total: 830am called, 12:30pm same day, all done…Two technicians arrived who were both professional, kind, and cautious to leave my house exactly as it was when they arrived. Shoes off outside, area rugs shifted out of the way, diagnosis was clear, estimate transparent, work was completed and then they cleaned all surfaces to ensure things were tidy as they packed up and moved the couple rugs back. Great experience!Thanks Fern!
