Recommended unit for New Brunswick
Given New Jersey’s humid continental / humid subtropical climate and gas water heating, high-efficiency gas is the sensible default for most New Brunswick 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.

Common water heater installation issues in New Brunswick
Permit and code compliance
New Jersey requires permits and inspections under the Uniform Construction Code; unpermitted work can lead to fines or issues during home sales.
Expansion tank requirement

Cold winter inlet water
Winter inlet water temperatures are cold, which can reduce recovery rates; a properly sized unit is essential for adequate hot water.
What to expect during installation
A licensed plumber will first obtain a permit from the city. They'll disconnect the old unit, install the new water heater per the 2021 NSPC, and add an expansion tank if needed. After installation, a municipal inspector will check the work. The job typically takes 4–8 hours for a standard replacement.
