Recirculation Tankless Upgrades in Leavenworth, KS
If you are tired of running the tap while you wait for hot water, a tankless with a built-in recirculation pump can bring heat to the fixture in seconds. Navien A series and Rinnai units with internal pumps can use a dedicated return line or a crossover valve under the farthest sink. We program schedules so the pump runs only during your morning and evening peaks. That keeps gas use reasonable while saving thousands of gallons of wasted water a year. This upgrade is a favorite in long single-story ranch homes.

Tank to Tankless Conversions in Leavenworth, KS
Converting from a 40 or 50 gallon tank to tankless frees up floor space and ends standby heat loss in a garage or closet. The catch is that tankless units often need a larger gas line, often three quarter inch or bigger, plus new venting. We check your meter size and pipe run before quoting so there are no surprises mid-job. We also cap or reroute the old flue and seal the roof penetration if it is no longer used. Plan for a conversion to take a full day.
Commercial Tankless Replacement in Leavenworth
Restaurants, salons and small offices often use multiple tankless units linked together on a rack system. When one or more units fail, we replace them and rebalance the cascade controls so they share the load. We check gas pressure under full demand, since commercial racks can draw more than 600,000 BTU combined. Scheduling is easy to work around, so we can work after hours and keep your business open. We also set up a descaling schedule matched to your water usage.
Rinnai Tankless Water Heater Replacement in Leavenworth
Rinnai is a leading brand in the tankless water heater market, known for its quality and engineering. If your Rinnai unit is aging or malfunctioning, KRV Plumbing provides expert Rinnai tankless water heater replacement in Leavenworth. We make sure your new Rinnai unit is installed correctly, extending its efficiency and lifespan. Our technicians know the installation requirements and venting options for Rinnai models, so the upgrade goes smoothly.
