Tank to Tankless Conversions in Lafayette
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 dispose of your old tank and patch the old flue penetration.

Hard Water Protection for Tankless Units in Lafayette, LA
Calcium scale is the leading cause of tankless heater failure. Private wells serve many rural homes, and sediment, iron, and bacteria make periodic well testing a good habit. 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.
