Step 1 of 3: Equipment
Snow-covered gable roof of a gray board-and-batten house with two windows, backed by snow-laden evergreen trees and falling snow.

Gas venting, combustion air supply, and the flue connection are not afterthoughts on a water heater install here. Utility gas heats more occupied homes in Adams County, Colorado than any other fuel, at 68.9% (2020-2024 ACS 5-year). A contractor quoting a replacement has to verify that the existing flue diameter, draft hood clearance, and gas line capacity all match the new unit before any work begins. Get those wrong and the heater either fails the inspector or runs at reduced efficiency from day one.

Unfinished basement with exposed wood joists and stud walls, galvanized sheet-metal ductwork overhead, a large stack of split firewood against a concrete block wall, and sawdust scattered on the concrete floor.

Ductwork is rarely the variable on a water heater job, but the electrical panel is. Half the homes in Adams County, Colorado were built in 1991 or earlier (2020-2024 ACS 5-year). A house built to that point was wired for the demands of its era, and a high-efficiency electric water heater draws more than what many of those panels were sized to handle. The contractor's first question is whether the existing service supports the new unit. If it does not, panel work enters the scope before the water heater itself is even priced.

What a Water Heater Installation Covers

The tank is the piece a homeowner notices first. It sits in a utility closet, basement, or garage and holds a supply of water kept ready at temperature. Attached to the top are the cold-water inlet and hot-water outlet, the two pipes that tie the tank into the house's plumbing.

The pressure relief valve mounts on the side of the tank and releases if pressure builds beyond a safe point. A drain valve sits near the base. The flue or venting assembly runs from the top of the tank upward and out, carrying combustion gases outside on gas-fired units.

The drawing shows a typical layout, and a licensed contractor determines what the installation requires for this specific house.
