Exterior Mount Tankless Units in South Lakes, AK
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. If you leave a home unheated, draining the plumbing or keeping the heat on with someone checking in is strongly recommended. 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 simplest swap when the gas line is already sized correctly.

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