Professional Tankless Water Heater Installation for Evansville, IN Families

Many homeowners install water softeners or iron filters to extend the life of their plumbing, and private wells are common in rural areas. We install service valves for easy flushing and recommend a scale inhibitor or softener to protect your warranty. You get efficient, endless hot water that keeps performing.

Tank to Tankless Conversions in Evansville
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.
Recirculation Systems for Tankless Heaters in Evansville
Tankless heaters can take a few extra seconds to deliver hot water to distant fixtures. A recirculation pump or dedicated return line keeps hot water close to faucets, cutting wait time and water waste. Some units have built-in pumps with smart scheduling. We design the system to suit your plumbing layout and usage patterns.
