Emergency Tankless Replacement in Summerville, SC
A tankless heater that leaks from the heat exchanger or refuses to ignite can leave you with no hot water at all. We offer same-day emergency replacement for common models and can often get a unit installed the day you call. If your exact model is not in stock, we can sometimes do a temporary repair to restore hot water while the replacement ships. We shut off gas and water to stop any leak as soon as we arrive. Call (864) 588-3813 any time your tankless quits.
Emergency Tankless Water Heater Replacement in Summerville

Tank to Tankless Conversions in Summerville, SC
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 Summerville
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 split 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 suited to your water usage.
Like-for-Like Tankless Swaps in Summerville
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 done in four to six hours.
