Tank to Tankless Conversions in Potomac, MD
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 usually 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. Expect a conversion to take a full day.

Recirculation Tankless Upgrades in Potomac, MD
If you are tired of running the tap waiting 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.
Commercial Tankless Replacement in Potomac
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 flexible, so we can work after hours and keep your business open. We also set up a descaling schedule matched to your water usage.
