Recommended unit for Somerville
Given New Jersey’s humid continental / humid subtropical climate and gas water heating, high-efficiency gas is the sensible default for most Somerville 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 Installation in Somerville, explained.
What affects installation cost in Somerville
Installation prices vary based on unit type (tank vs. tankless), the need for a new gas line ($275–$950), and whether your home has a closed system requiring an expansion tank. Older homes (median built 1958) may need additional piping or venting upgrades to meet the National Standard Plumbing Code. Labor rates reflect local costs, and permits add a fee. Federal 25C tax credits (30% up to $2,000) apply only to qualifying heat pump water heaters, not gas units.
