Tank to Tankless Conversions in Ellsworth, 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 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.

Emergency Tankless Water Heater Replacement in Ellsworth
A sudden tankless water heater failure can leave your Ellsworth home without hot water, which is a serious inconvenience. BKN Plumbing offers emergency tankless water heater replacement to restore your hot water fast. We prioritize urgent situations, working to diagnose the issue and, if replacement is necessary, get a new unit installed as soon as possible. Our goal is to cut down your downtime and get your home back to normal with reliable hot water.
Exterior Mount Tankless Units in Ellsworth, 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. Seasonal camps and cottages are usually drained and winterized each fall, and many year-round homes use heat tape and pipe insulation. 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.
Gas Tankless Water Heater Replacement in Ellsworth
Many homes in Ellsworth rely on natural gas for water heating, and gas tankless units are a very efficient option. Our gas tankless water heater replacement service includes thorough inspection of your existing gas lines, proper sizing of new gas lines if needed, and secure venting to the outdoors. We prioritize safety. All gas connections and combustion air requirements meet Maine and local codes, heading off potential hazards and maximizing efficiency.
Navien Tankless Water Heater Replacement in Ellsworth, ME
Navien tankless water heaters are popular for their condensing technology, delivering high efficiency and performance. When it is time for a Navien tankless water heater replacement in Ellsworth, ME, you can count on BKN Plumbing. We have extensive experience with Navien's advanced systems, including their combination boiler and water heater units. Our installation process focuses on dialing in your new Navien's performance, so you benefit from its energy-saving features and reliable hot water output.
Condensing Tankless Replacement in Ellsworth
Condensing tankless units like the Navien NPE series or Rinnai Sensei reach efficiencies above 90 percent by recovering heat from exhaust gases. They vent through inexpensive PVC and produce acidic condensate that must be neutralized and drained properly. We install a neutralizer cartridge and route the condensate line to an approved drain. Short summers and long winters mean freeze protection and boiler maintenance are top priorities for most homeowners. Condensing units still save gas because they work year-round on showers, laundry and dishes. We explain the cost difference so you can decide if the efficiency gain is worth it.
Commercial Tankless Replacement in Ellsworth
Restaurants, salons and small offices often use multiple tankless units linked together on a rack system. When one or more units fail, we replace them and rebalance the cascade controls so they split the load. We check gas pressure under full demand, since commercial racks can draw more than 600,000 BTU combined. Scheduling is flexible, so we can work after hours and keep your business open. We also set up a descaling schedule suited to your water usage.
