Water heater replacement cost by type.
Installed prices for Largo, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Largo, Maryland, replacing a water heater typically costs between $750 and $3,700 depending on the type and installation complexity. Most homes were built around 1983, so older units may need code-compliant updates like an expansion tank if your system has a check valve or pressure-reducing valve. With humid subtropical winters and cold incoming water, a heat pump water heater is often a strong fit, especially with the federal 25C tax credit covering 30% of the cost up to $2,000. All work must be done by a Maryland-licensed master plumber and pass a final local inspection before the unit is placed in service.

Recommended unit for Largo
Given Maryland’s humid subtropical climate and mixed water heating, heat-pump (hybrid) is the sensible default for most Largo homes. 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.

Prices vary 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).

Common water heater problems in Largo
Sediment buildup
Hard water and age cause sediment to collect at the tank bottom, reducing efficiency and leading to rumbling noises or premature failure.
Leaking T&P valve
A faulty temperature and pressure relief valve can drip or discharge water, often due to high pressure or thermal expansion in closed systems.
Corroded anode rod
The anode rod protects the tank from rust but wears out over time, especially in older homes with metal piping, leading to leaks or tank failure.
