Large Capacity 75 Gallon Gas Heaters in Charleston, SC
Big families, soaking tubs and multiple showers running at once often need a 75 gallon tank or a high-recovery 50 gallon model. These heaters use larger burners, sometimes 75,000 BTU, and may need a bigger gas line and flue. We check your meter and pipe size to make sure the larger tank gets the gas it needs. A high-recovery unit can be a good middle ground when space is tight. We walk you through recovery rates so you pick the right fit.

Standard Vent Gas Water Heater Replacement in Charleston
Many homes in Charleston rely on standard atmospheric vent gas water heaters. When these units reach the end of their lifespan, typically 10 to 12 years, we provide professional replacement. Our service includes safely disconnecting the old unit, installing a new, energy-efficient model, and connecting it properly to your existing natural gas line and flue venting system. We also check for adequate combustion air and perform a thorough leak test for safety and efficiency.

A sudden water heater failure can be a serious disruption. KBN Plumbing offers emergency gas water heater replacement services across Charleston, SC to get your hot water back quickly.

Tankless Gas Water Heater Conversion in Charleston
If you are looking to switch from a traditional tank to a tankless gas water heater, KBN Plumbing can manage the entire conversion in Charleston. This often involves upgrading gas lines to handle higher BTU requirements and possibly modifying venting systems. We assess your home's infrastructure for a seamless and code-compliant transition, providing endless hot water on demand.
Commercial Gas Water Heater Services in Charleston, SC
Businesses in Charleston, SC have higher demands for hot water, requiring robust commercial-grade gas water heaters. KBN Plumbing provides expert replacement services for commercial properties, so your new unit is sized correctly for your business's needs. We handle the complexities of larger units, higher BTU inputs and commercial venting requirements, minimizing downtime for your operations.
Power Vent Water Heater Replacement in Charleston
Power vent gas water heaters use an electric blower to push exhaust through PVC pipe, which lets them sit far from a chimney or roof flue. When the blower motor or pressure switch fails again and again, replacing the whole unit can be the better choice. We install new power vent models and confirm a dedicated outlet is available. Venting length and number of elbows must stay within the manufacturer's limits. Power vent tanks cost more but solve difficult placement problems.
40 and 50 Gallon Tank Replacement in Charleston
The 40 and 50 gallon gas tank is the workhorse of most South Carolina homes. When yours starts leaking from the bottom seam or produces rusty water, replacement is the only true fix. We match the new tank's height and diameter to your space and reuse the venting when it is in good shape. Newer tanks are sometimes taller due to efficiency standards, so we check clearance before ordering. Most of these jobs take about two to three hours.

Commercial Gas Water Heater Replacement in Charleston, SC
Beyond residential services, KBN Plumbing also handles commercial gas water heater replacement in Charleston, SC. Businesses, from restaurants to offices, have unique hot water needs. We install heavy-duty, high-capacity gas water heaters designed for commercial use, so your business operations run smoothly.
