Water heater replacement cost by type.
Installed prices for Trenton, adjusted for local labor. Larger tanks and code upgrades move the number up.
Water heater replacement in Trenton, Ohio typically costs between $700 and $1,800 for a gas tank unit, $800–$2,000 for electric tank, $1,350–$3,200+ for tankless, and $1,600–$3,600 for a heat pump model. Most homes use gas, and with cold winters and cold inlet water, a gas tank water heater is a recommended choice for reliable performance. Permits are required under the Ohio Plumbing Code (based on 2021 IPC), and an expansion tank may be needed if your system has a check valve or pressure-reducing valve. A drain pan is not required for replacements where one wasn't previously installed. Local labor rates reflect the area's median income of $84,392, and the typical home built in 1992 may need updated venting or connections.

Recommended unit for Trenton
Given Ohio’s humid continental (cold winters) climate and gas water heating, high-efficiency gas is the sensible default for most Trenton 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.

Water Heater Replacement in Trenton, explained.
What affects your water heater replacement cost in Trenton
The main factors are unit type (gas tank, electric tank, tankless, or heat pump), labor rates, and any code-required upgrades like an expansion tank. Gas tank units are generally more affordable than tankless or heat pump models. The age of your home (median built 1992) may require venting or gas line modifications. Permits add a small fee, and if your system is closed, an expansion tank is required. The federal 25C tax credit (30% up to $2,000) can lower the cost of a qualifying heat pump water heater, but Ohio's HEAR rebates had not launched as of mid-2026.
