Tank to Tankless Conversions in Fort Smith
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 often 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.

Tankless water heaters offer several key benefits: endless hot water on demand, significant energy savings from heating water only when needed, a longer lifespan (often 20+ years) and a compact, space-saving design. They also reduce the risk of tank leaks and the water damage that comes with them.
Signs you might need a new water heater, tankless or otherwise, include a lack of hot water, rust-colored water, strange noises from the unit or frequent leaks. For tankless systems specifically, frequent error codes or a noticeable drop in hot water flow could point to a need for service or replacement.
We install Rinnai, Navien, Noritz and Rheem tankless water heaters. Each brand offers different features, efficiency levels and warranties.
While it may seem appealing, tankless water heater installation is complex and should only be performed by a licensed professional. It involves gas lines, high-voltage electricity, water connections and detailed venting systems, all of which require specialized knowledge and adherence to safety codes. Incorrect installation can be dangerous and void warranties.
Many manufacturers offer 10 to 15 year heat exchanger warranties and shorter coverage on parts. We also guarantee our installation labor.
A standard tankless water heater installation, replacing an existing tank, usually takes 4 to 8 hours. If extensive plumbing or gas line changes are required, it may take a full day. Our team works efficiently to restore your hot water as quickly as possible.
Yes, gas tankless water heaters require specific venting materials and configurations different from traditional tank heaters. Many modern units use PVC or polypropylene for venting, and proper slope and termination are critical for safe and efficient operation. Electric units do not need venting.
