FAQs
How quickly can you install a tankless water heater in Karns?
Because we keep the most popular gas and electric tankless units in stock in our Karns warehouse and staff a dedicated emergency crew, we can usually arrive within 2–3 hours of your call and complete most installations the same day. A typical swap-out of a conventional tank for a new tankless system takes 4–6 hours, including removal of the old heater, mounting the new unit, making gas or electrical upgrades, connecting water lines, and testing the system.
What brands and sizes of tankless water heaters do you carry for same-day service?
We stock high-efficiency models from Rinnai, Navien, Rheem, and Noritz in flow-rates from 6.5 GPM to 11 GPM. Both natural-gas and electric units are available, so we can match the heater to the size of your household and the type of utility service you already have. Larger or specialty units can be ordered, but those may require next-day delivery rather than same-day installation.
Is my home in Karns eligible for a same-day tankless water heater upgrade?
Almost any single-family home, condo, or light-commercial space served by KUB or LCUB utilities qualifies. The main requirements are: ample gas line capacity (¾″ minimum for most gas units), a 120 V outlet for the ignition system, and exterior or venting access for combustion air. If those elements are missing, we can often add or modify them on the same visit, but we will confirm during a quick phone or video assessment before dispatching a crew.
How much does a same-day tankless installation cost?
Total investment usually falls between $2,800 and $4,500, which includes the heater, vent kit, isolation valves, dedicated flush port, removal of the old tank, permits, and labor. Gas line upgrades or electrical work can add $150–$600. We provide an upfront, flat-rate quote before work starts, and we accept major credit cards, financing, and utility rebates where applicable.
Will a tankless water heater really save me money on my utility bills?
Yes. Tankless units only heat water when a fixture is opened, eliminating standby losses that cause conventional tanks to cycle 24/7. Energy Star–rated models we install in Karns are typically 95 % efficient and can cut natural-gas or electric water-heating costs by 20–40 %. They also last 20+ years—about double the life of a storage tank—providing long-term savings on replacement costs.
Do you handle permits, inspections, and disposal of my old water heater?
Absolutely. We pull the required plumbing and mechanical permits from Knox County, schedule the final inspection, and haul away the old tank for environmentally responsible recycling. You don’t have to coordinate anything—our turnkey service allows you to start enjoying endless hot water the very same day you call.
