Exterior Mount Tankless Units in Coral Gables, FL
Many homes have tankless heaters mounted on an exterior wall with no venting at all, since the unit exhausts directly outside. These units face sun, rain and temperature swings, which can break down plastic covers and wiring over time. Frozen pipes are rare in most of Florida, and many homes have outdoor plumbing that would never hold up in a northern winter. When we replace them, we check the pipe cover, freeze protection settings and the electrical connection. We can add a protective pipe cover kit to shield the water and gas lines. Exterior models are often the easiest swap when the gas line is already sized correctly.

Navien tankless water heaters are popular for their condensing technology, offering high efficiency and performance.

Like-for-Like Tankless Swaps in Coral Gables
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.
Residential Tankless Water Heater Replacement in Coral Gables
For homeowners in Coral Gables, upgrading to a tankless water heater offers real benefits like endless hot water and reduced energy use.

That includes any needed gas and water line adjustments and venting changes to meet current codes.
Tank to Tankless Conversions in Coral Gables, FL
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 evaluate 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.
Emergency Tankless Replacement in Coral Gables, FL
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 (904) 925-7356 any time your tankless quits.
