Exterior Mount Tankless Units in Fort Smith, AR
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. Crawlspace pipes, exterior wall lines, and outdoor faucets are the most common freeze failures, so insulation and vent covers make a real difference. 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.
