Exterior Mount Tankless Units in Warner Robins, GA
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 wear out plastic covers and wiring over time. Hard freezes are occasional in Georgia, but when a cold snap arrives, homes built for heat often have exposed pipes in crawlspaces, attics, and exterior walls. 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 guard the water and gas lines. Exterior models are often the easiest swap when the gas line is already sized correctly.
Tank to Tankless Conversions in Warner Robins, GA
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.

For properties without natural gas access or those looking for an all-electric solution, electric tankless water heaters are a viable choice.

However, it often requires changes to gas lines, venting and possibly electrical wiring, making professional installation essential for safety and performance.

With proper installation and regular maintenance, a new tankless water heater usually lasts 20 to 25 years. This is much longer than traditional tank water heaters, which usually last 10 to 15 years. Regular flushing and descaling can help extend the life of your tankless unit, especially in areas with hard water.

To prepare for tankless water heater replacement, make sure the area around your existing unit is clear and easy to reach for our plumbers. If possible, clear a path to the installation site and keep pets or children safely out of the work area. We will handle draining the old unit and all other technical preparations.
Most manufacturers offer 10 to 15 years on the heat exchanger and about 5 years on parts for residential use. We add our own labor warranty and register the unit on your behalf.
A standard tankless water heater replacement, if you are upgrading from an existing tankless unit, typically takes 4 to 8 hours. If you are converting from a traditional tank water heater, the process can take longer, possibly a full day, due to additional plumbing, gas or electrical changes required for proper installation and venting.
