SIZING

What Size Water Heater Do I Need?

Size from peak hour demand: number of people, bathrooms used at once, laundry overlap and fixture flow—not the square footage of the house. In Charlotte, many two-person homes stay on a 40-gallon electric package; families stacking showers usually need 50 gallons or a higher FHR.

PUBLISHED INSTALLED PRICING

Real installed numbers—not an uninstalled tank.

50-GAL ELECTRIC

$1,349 + tax

A practical Charlotte shortcut

  • 1–2 people, 1–2 baths, staggered use → 40-gallon electric ($1,199 + tax package) is often enough.
  • 3–4 people or 2+ baths used together → start at 50-gallon electric ($1,349 + tax).
  • Soaking tubs, body sprays or back-to-back showers → confirm FHR; consider 50-gal or tankless with real GPM math.
  • Gas vs electric changes recovery: gas often reheats faster, so a smaller gas tank can sometimes match a larger electric.

First Hour Rating beats the gallon sticker

Manufacturers publish FHR: how much hot water the unit can deliver in an hour starting with a full tank. We match FHR to your peak hour rather than arguing 40 vs 50 as a personality test.
