Water heater replacement cost by type.
Installed prices for Rexburg, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Rexburg, Idaho, where the median home was built in 2005 and winter inlet water is cold, replacing a water heater involves specific local considerations. Typical installed costs range from $650–$1,650 for a tank gas unit, $750–$1,800 for tank electric, $1,250–$2,900+ for tankless, and $1,500–$3,300 for a heat pump model. Because Rexburg is a smaller market with a low homeownership rate (20.2%), most replacements are for rental properties or newer homes, but homeowners can pull their own permit under an owner-builder exemption. Idaho follows the UPC, requiring permits and expansion tanks on closed systems. The cold climate and mostly gas heating make tank gas a common choice, but heat pump units qualify for the federal 25C tax credit (30% up to $2,000).

Winter inlet water runs cold here, so recovery rate matters — size up a tankless or favor a high-recovery tank. A pro can confirm the right size and fuel for your home.

Finally, the federal tax credit can lower the net cost of a heat pump water heater.
