Tank to Tankless Conversions in Butte, 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.

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.

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 real savings on your utility bills over time, especially in homes with varying hot water usage.
DIY tankless water heater replacement is usually not recommended due to the complexity of gas lines, high-voltage electricity, water connections and venting requirements. Improper installation can lead to serious gas leaks, carbon monoxide poisoning, water damage or electrical hazards. It is best to hire a licensed and experienced plumber like DFV Plumbing.
We install Navien, Rinnai, Noritz, Takagi and Rheem tankless heaters. Each has strengths, and we recommend based on your flow needs, venting options and budget.
A standard tankless water heater replacement usually takes between 4 and 8 hours. This timeframe can vary based on whether we are replacing an existing tankless unit with a similar model or upgrading from a traditional tank water heater. A tank conversion can call for more extensive changes to gas lines, electrical or venting.
We do not recommend it. Gas line sizing, venting clearances and combustion testing require training, and improper installs can void the warranty or create carbon monoxide hazards.
A direct swap usually takes four to six hours. A tank to tankless conversion with new gas and venting usually takes a full day.
Yes, you can absolutely replace a traditional tank water heater with a tankless unit. This is a common upgrade for homeowners looking for better energy efficiency and endless hot water.
