Emergency Tankless Replacement in Brunswick, ME
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 usually 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.

Gas Tankless Water Heater Replacement in Brunswick
Many homes in Brunswick rely on natural gas for water heating, and gas tankless units are a very efficient option.

We put a priority on safety. All gas connections and combustion air requirements meet Maine and local codes, preventing potential hazards and maximizing efficiency.
Tank to Tankless Conversions in Brunswick, ME
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 usually need a larger gas line, often three quarter inch or bigger, plus new venting. We check 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. Expect a conversion to take a full day.
Exterior Mount Tankless Units in Brunswick, ME
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. Frost reaches deep into the ground, so water and sewer lines in Maine must be buried safely below the frost line. 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 simplest swap when the gas line is already sized correctly.
