Tankless vs. Tank Water Heater Conversion in Rochester, NH

Like-for-Like Tankless Swaps in Rochester
When your existing tankless has a cracked heat exchanger or a failed control board that is not worth repairing, a direct replacement is often the fastest fix. We match the new unit to your current gas line, venting type and mounting location whenever possible. Many Rinnai and Navien models share similar footprints, which keeps wall patching to a minimum. We also replace the old service valves if they are corroded or stuck. Most like-for-like swaps are finished in four to six hours.
Tank to Tankless Conversions in Rochester, NH
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. Plan for a conversion to take a full day.

We prioritize safety. All gas connections and combustion air requirements meet New Hampshire and local codes, preventing potential hazards and maximizing efficiency.
Recirculation Tankless Upgrades in Rochester, NH
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.

This upgrade is a favorite in long single-story ranch homes.
