Hard Water Protection for Tankless Units in Missoula, MT
Calcium scale is the most common cause of tankless heater failure. Water across much of Montana is moderately hard to hard, especially from wells, so scale buildup in water heaters and faucets is common. Scale coats the heat exchanger, reducing efficiency and triggering error codes. We install isolation valves so the unit can be flushed with a vinegar or descaling solution once a year. A scale inhibitor cartridge or whole-home softener provides extra protection.

Tank to Tankless Conversions in Missoula
Converting from a tank requires more than swapping units. A 40 gallon tank heater uses roughly 40,000 BTU, while a whole-home tankless unit may need up to 199,000 BTU, so the gas line usually needs to be upsized. Venting changes from a metal flue to PVC or stainless, and the unit moves to a wall location. We remove and haul away your old tank and patch the old flue penetration.

Most tankless water heaters come with a manufacturer's warranty of 10 to 15 years on the heat exchanger and 3 to 5 years on parts. DFV Plumbing also provides a warranty on our installation labor, which we will spell out in your service agreement.
Yes, installing a new tankless water heater or replacing an existing one in Missoula typically requires a plumbing permit. This ensures the installation meets local building and safety codes. DFV Plumbing handles all necessary permitting paperwork for you.
