12.7% Rate Hike Renews Focus on Water Heater Efficiency

Proposed 12.7% Electric Rate Increase Has Charleston Homeowners Asking About Water Heater Costs

Summerville, United States – May 13, 2026 / Yeehaw Plumbing /

With South Carolina regulators considering a proposed 12.7% increase in residential electric rates, homeowners across the Charleston area are looking for practical steps to reduce household energy costs before higher bills arrive.

Yeehaw Plumbing, a locally owned company serving Berkeley, Charleston, and Dorchester counties, reports that water heater inquiries have risen noticeably over the past several months, with many residents seeking guidance on whether their current setup is contributing to unnecessary energy use.

“The water heater is one of the biggest energy users in most homes – and a lot of folks don’t realize how much an old, inefficient one is costing them every month,” said Seth McAulay, owner of Yeehaw Plumbing and a South Carolina-licensed plumber. “With bills going up, people want to know what’s in their control. We’ve seen a real uptick in calls about tankless conversions, sediment flushes on older tanks, and homeowners just wanting to understand whether their setup is costing them more than it should.”

What Lowcountry homeowners can actually do

McAulay notes that the homeowners who benefit most from a professional assessment are not always those who require a full system replacement. “Sometimes the answer is a $200 service call, not a $4,000 replacement. We’d rather have an honest conversation and tell somebody their tank has another five good years in it than sell them something they don’t need.”

For those considering an upgrade, Yeehaw Plumbing outlines several common options. A tankless water heater heats water on demand and typically uses 24%-34% less energy than a standard tank for the average household. High-efficiency tank replacements offer another path for homeowners not ready to convert. For units still in serviceable condition, basic maintenance – flushing sediment buildup, inspecting the anode rod, and verifying thermostat settings – can meaningfully extend equipment life and improve performance. A licensed plumber in Summerville, SC or the broader Charleston area can evaluate which option fits a given home’s age, usage, and budget.

Hurricane season is the other deadline

Rising utility costs are not the only concern on Lowcountry homeowners’ calendars. The 2026 Atlantic hurricane season officially begins June 1, and forecasters at Colorado State University and AccuWeather are projecting an active-to-near-average season with the potential for several U.S. landfalls.

“We see the same thing every year after a storm,” McAulay said. “Failed sump pumps, water heaters knocked out by power surges, supply lines that should’ve been replaced two years ago. The folks who get through it cleanest are the ones who did the boring stuff in May.”

Yeehaw Plumbing’s pre-season checklist includes testing sump pumps, checking shut-off valves, inspecting water heaters for signs of corrosion, and locating the main water shut-off before a storm event. Homeowners who delay water heater repair in Charleston or routine maintenance often face longer wait times and higher costs in the aftermath of severe weather, when demand for licensed plumbers spikes across the region.
