Space Considerations for Your New Water Heater Installation

May 14, 2025

A couple in nearby Tackle Ave bought a new water heater without measuring the space first. When the installer arrived, the unit wouldn’t fit through the basement door. The whole job had to be rescheduled, and they ended up paying extra to move gas and water lines.

It’s a surprisingly common mistake. And it’s one you can avoid with the right info from Garon T Plumbing, Heating, AC & Electric. Here, experts in water heater repair in Brick Township, NJ, discuss space considerations for installing a new water heater.

Measure Before You Buy

Before shopping for a new unit, grab a tape measure and check the size of your current water heater. Look at the height, width, and depth — but don’t stop there. Measure the doorway, the hallway, and any tight corners the water heater replacement unit will need to pass through.

Make sure you know:

  • Clearance from walls or other appliances
  • Floor space for tank units
  • Ceiling height if it’s a tall model

This helps you avoid buying a unit that’s too big for your home’s layout.

Know Your Heater Type

Different water heaters need different amounts of space. If you are looking to replace an old model with one with a bigger tank, you will need to make adjustments.

Meanwhile, if you are looking to buy a tankless water heater, you will need to set up mounts, but they still need ventilation. Traditional tank units are bulky and need clearance all around for airflow and maintenance.

Quick comparison:

  • Tank models: Require more space, including 6 inches around the tank for ventilation
  • Tankless models: Great for tight spaces, but need a proper wall mount and vent setup

Choose based on your household needs and your available space.
