Dependable Tankless Water Heater Replacement Services in Janesville, WI

Exterior Mount Tankless Units in Janesville, WI

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. Insulating pipes on exterior walls, shutting off outdoor faucets and keeping garages warm prevent most freeze damage. 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.
