Step 1 of 3: Equipment
A gray electrical panel with conduit running above and below is mounted on a cream concrete block wall beside a coiled gray cable, with an open garage interior and shelving visible at left.

Ductwork laid out for older systems does not automatically carry what a replacement water heater installation asks of it. Half the homes in McKinley County, New Mexico were built in 1985 or earlier (2020-2024 ACS 5-year). A contractor working in stock like this has to open up what is already in the house and check the routing, the sizing, and what the existing electrical service will support, before the unit itself is even on the table. Those two things, the duct path and the electrical, decide how the job goes.

What Gets Installed With a New Water Heater

The tank or tankless unit is the heart of the installation. A storage-tank model sits in a utility closet, basement, or garage and holds a reservoir of heated water ready for use. A tankless unit mounts to a wall and heats water on demand as it passes through.

The pressure relief valve mounts directly on the tank and opens if pressure inside climbs too high. The supply and discharge lines connect the unit to the home's cold-water feed and to every fixture in the house. A drain pan sits beneath the unit to catch any water before it reaches the floor.

The drawing shows a typical layout, and a licensed contractor determines what fits and what applies in your specific home.
