Installed prices for Merrifield, adjusted for local labor. Larger tanks and code upgrades move the number up.

What Affects Your Water Heater Cost in Merrifield
Prices vary primarily by unit type: tank gas ($750–$1,850), tank electric ($850–$2,100), tankless ($1,400–$3,300+), and heat pump ($1,700–$3,700).

Since Virginia has not yet launched state rebates, the federal 25C tax credit for heat pump models is the main incentive.
