Water heater replacement cost by type.
Installed prices for Portsmouth, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Portsmouth, Virginia, replacing a water heater typically costs between $750 and $3,800 depending on the type and complexity. With half the homes built around 1966, many systems are aging and may require code updates like expansion tanks on closed systems. The humid subtropical climate and moderate winter inlet water temperatures make heat pump water heaters a strong fit, especially with the federal 25C tax credit covering 30% of the cost up to $2,000. Local labor rates reflect the median household income of $57,154, and a permit is always required even for like-for-like swaps.

What Affects Your Water Heater Replacement Cost in Portsmouth
The main cost drivers are the type of unit—tank gas ($750–$1,900), tank electric ($850–$2,100), tankless ($1,400–$3,300+), or heat pump ($1,700–$3,800)—and the condition of existing connections.
