We size, install and set up each replacement so it holds up to your local water supply.

Commercial Tankless Replacement in Bozeman
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.

Electric Tankless Water Heater Replacement in Bozeman, MT
For properties without natural gas access or those looking for an all-electric solution, electric tankless water heaters are a practical choice. DFV Plumbing offers electric tankless water heater replacement services in Bozeman, MT. This often involves close assessment of your home's electrical panel capacity, as these units require substantial amperage. We make sure your new electric tankless unit is installed safely and correctly, providing on-demand hot water without the need for gas lines.
Recirculation Tankless Upgrades in Bozeman, MT
If you are tired of running the tap while you wait for hot water, a tankless with a built-in recirculation pump can bring heat to the fixture in seconds. Navien A series and Rinnai units with internal pumps can use a dedicated return line or a crossover valve under the farthest sink. We program schedules so the pump runs only during your morning and evening peaks. That keeps gas use reasonable while saving thousands of gallons of wasted water a year. This upgrade is a favorite in long single-story ranch homes.
Commercial Tankless Water Heater Replacement in Bozeman, MT
Businesses in Bozeman, MT often require robust hot water solutions, and tankless systems can provide the efficiency and capacity needed. We regularly replace commercial tankless units for restaurants, offices and other facilities with minimal disruption to your operations. Our plumbers are skilled with high-capacity models and complex plumbing layouts. We deliver a steady hot water supply that meets your business's demands and health code requirements.
Tank to Tankless Conversions in Bozeman, MT
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 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.
Exterior Mount Tankless Units in Bozeman, MT
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. Pipes in exterior walls, crawlspaces, cabins and seasonal homes are especially likely to freeze during long cold spells. 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.

Frequently Asked Questions About Tankless Water Heater Replacement in Bozeman
The cost of tankless water heater replacement in Bozeman, MT usually ranges from $3,000 to $6,000, depending on the unit's capacity, brand, complexity of installation, such as converting from a tank model, and any needed electrical or gas line upgrades. This price usually includes the unit itself and labor. We provide a detailed, upfront quote after a thorough assessment of your home.
Often yes, especially when converting from a tank. Many tankless units need three quarter inch gas pipe and a meter that can handle 199,000 BTU on top of your furnace, range and dryer.
To prepare for tankless water heater replacement, make sure the area around your existing unit is clear and easy to reach for our plumbers. If possible, clear a path to the installation site and keep pets or children safely out of the work area. We will handle draining the old unit and all other technical preparations.
Yes, in most areas of Bozeman and Montana, a permit is required for tankless water heater replacement, especially if it involves gas line changes or significant electrical work. Our team at DFV Plumbing will handle all necessary permitting so your installation is fully compliant with local building codes and safety regulations.
Yes, tankless water heaters are usually more energy-efficient than traditional tank models. They only heat water on demand, eliminating the standby heat loss that comes with keeping a large tank of water hot. This can lead to significant savings on your utility bills over time, particularly in homes with varying hot water usage.
Most manufacturers offer 10 to 15 years on the heat exchanger and about 5 years on parts for residential use. We add our own labor warranty and register the unit for you.
A standard tankless water heater replacement, if you are upgrading from an existing tankless unit, typically takes 4 to 8 hours. If you are converting from a traditional tank water heater, the process can take longer, possibly a full day, due to additional plumbing, gas or electrical changes required for proper installation and venting.
With proper installation and regular maintenance, a new tankless water heater typically lasts 20 to 25 years. This is much longer than traditional tank water heaters, which usually last 10 to 15 years. Regular flushing and descaling can help extend the life of your tankless unit, especially in hard water areas.
