Water Heater Installation in Union County, NJ — New Construction, Additions & Conversions

Building, adding on, or upgrading from tank to tankless? A new water heater installation is more than a swap — it's a project. We handle every part.

Whether you're finishing a basement, adding an in-law suite, or converting your old tank to a tankless system, a water heater installation involves gas lines, venting, electrical, code compliance, and timing with other trades. Continental Plumbers has been installing water heaters across Union County since 1985 — for new construction, home additions, and homeowners upgrading to better systems. We coordinate with your GC, your designer, or run the whole plumbing scope ourselves if you're managing the project.

When You Need a New Installation

Five Times You Need an Installation, Not a Replacement

“Replacement” is swapping an old unit for a new one. “Installation” is a bigger project. Here’s when an installation is the right call:

New Home Construction

Building a home from scratch. Water heater rough-in, gas line, venting, and final install — coordinated with your GC and other trades.

Home Addition or Finished Basement

Adding square footage that includes a bathroom, kitchenette, or laundry — usually means adding hot water capacity. Sometimes a second water heater, sometimes upgrading the main one.

Converting Tank to Tankless

Big upgrade. Requires new venting, possible gas line upsize, and electrical work in some cases. Not the same as a like-for-like replacement.

We Get It

The Concerns We Hear About New Installations

"I'm doing a remodel — when should I bring in the plumber?"

As early as possible. The water heater install needs to be planned around your other trades — framing, drywall, electrical, gas line, and venting routes. Bringing us in during the planning phase prevents expensive rework later.

"I want tankless, but I'm not sure my house can handle it."

Common concern. Most Union County homes can be converted to tankless, but some need gas line upgrades, panel work, or different venting. We do a free site assessment to tell you what's actually involved — before you commit.

"My contractor said the plumbing isn't until later. Should I wait to talk to you?"

No. Even if the install itself happens later, decisions on location, gas line sizing, and venting need to be made now. A 15-minute conversation early saves days of delays later.

"I'm adding rental units. Can you handle multi-unit installs?"

Yes. We handle multi-unit water heater installations across Union County — building additions, new ADUs, and commercial spaces. Coordinated installs, clear billing, documented for your records.

Permits, Code & Inspections

Code-Compliant, Permitted, Inspected

Every new water heater installation in NJ requires a permit. Skipping the permit is one of the most common reasons installations fail when you sell the house, file an insurance claim, or have a problem.
