Gas vs. Electric Tankless Water Heaters: Which Is Right?
Tankless water heaters deliver hot water on demand without storing 50 gallons of heated water around the clock. For West Columbia, SC homeowners looking to cut energy costs and free up mechanical room space, tankless is a strong option. Merritt Plumbing installs gas and electric tankless water heaters throughout West Columbia and Lexington County. We size the unit correctly for your household demand, upgrade the gas line or electrical service if needed, and install with all required permits. An undersized tankless unit is a common installer mistake — we calculate correctly from the start. Call (803) 254-7542 for a tankless water heater assessment and quote.
What Does Tankless Water Heater Installation Cost in West Columbia, SC?
Gas tankless units heat water significantly faster and handle higher simultaneous demand. A whole-house gas tankless unit with a 180,000–199,000 BTU burner handles most four-bedroom West Columbia homes. Electric tankless units work for point-of-use applications — a single bathroom addition or kitchen sink — but whole-house electric tankless requires a 200-amp service and multiple high-amperage circuits that many older homes don’t have. Most whole-house conversions in West Columbia use gas. If you’re on a slab with gas service, conversion from a tank to tankless is straightforward. We assess your current gas line capacity and upgrade it if needed.
Why Choose Merritt Plumbing for Tankless Installation?
Tankless installation in West Columbia runs $1,800–$3,500 for a whole-house gas unit including the heater, installation labor, gas line upgrade (if needed), and permit. Point-of-use electric units run $400–$800 installed. Whole-house electric tankless runs $2,500–$4,500 including electrical service upgrade. We provide written quotes after assessing your gas or electrical capacity. Manufacturer rebates and energy efficiency incentives sometimes apply — we identify applicable rebates during the assessment. Call (803) 254-7542.
Is Your Home Ready for Tankless?
Merritt Plumbing is licensed and insured in South Carolina. We install Rinnai, Navien, and Rheem tankless units and know the installation requirements that preserve manufacturer warranties — proper gas line sizing, correct venting, and water quality treatment where needed. Tankless units are sensitive to mineral scale and require descaling service every 1–3 years in areas with hard water. We install isolation valves and service ports that make descaling fast and inexpensive. All installations include permit pull and Lexington County inspection. Written labor warranty on all tankless installation work.
What's Included in a Tankless Water Heater Installation
Gas tankless units require a dedicated gas line sized for the BTU demand (typically 3/4-inch pipe minimum), proper venting (direct vent or power vent to the exterior), and a 120V electrical outlet nearby for the electronics. Electric whole-house tankless requires 200-amp service and multiple 30-amp or 40-amp circuits. We assess all of these during a pre-installation walkthrough. If upgrades are needed, we quote them upfront so there are no surprises. Older homes sometimes need gas line upgrades or new venting runs — common in West Columbia and worth planning for before the installation day.
