Water heater replacement cost by type.
Installed prices for Denison, adjusted for local labor. Larger tanks and code upgrades move the number up.
For Denison homeowners, replacing a water heater is a significant home expense. With a median home age of 58 years, many homes have older units that need replacement. Typical installed costs in Denison range from $650–$1,600 for a gas tank model, $750–$1,800 for electric tank, $1,200–$2,800+ for tankless, and $1,450–$3,200 for a heat pump unit.
