Water Heater Installation and Replacement in Lafayette

A new water heater is a choice among tank sizes, fuel types, venting and efficiency ratings. The best time to make it is before the old one fails, when you can compare options without a cold shower hanging over the decision.

Take a photo of the data plate on your current heater before you call.

Choices to make

  • SizeMatched to how many people use hot water at once.
  • FuelGas, electric or a heat pump unit.
  • Tank or tanklessA trade-off in space, cost and flow.

Sizing for the household

The first-hour rating on the yellow label, not just the gallon capacity, tells you how much hot water a tank can deliver in a busy hour. A family of four with two bathrooms usually wants a bigger tank than a couple in a condo.

The installer should ask about showers, a soaking tub, laundry habits and a dishwasher. A tank that is too small runs out. An oversized one burns energy holding water hot.

Gas, electric and heat pump models

Gas models recover fast and usually cost less to run when gas service exists. They need a vent to the outside and combustion air. Electric tanks need no vent and are simple to install, but they cost more to run.

Heat pump water heaters pull heat from the surrounding air and use much less electricity. They need space and a drain for condensate, and they cool the room around them, which is a small plus in a hot basement.

Cost

Factors behind a new water heater's price

Price follows the unit, the venting and the work needed around it.

  • 1Tank size and type. A larger or high-efficiency model costs more.
  • 2Venting and gas work. A new vent path or a longer gas run adds labor.
  • 3Code upgrades. An expansion tank, pan and updated valves may be required.
  • 4Permit and haul-away. Both can appear as separate lines.

Ask for a written quote that names the model, the size and what is included.

Elevation and hard water

Gas appliances are rated for specific elevations, and Lafayette sits at about 5,266 feet. Ask the installer to confirm that the unit and its burner are set up for that height.

Hard water scale shortens a tank's life. A regional estimate lists the area at roughly 9 grains per gallon. A softener upstream of the heater, plus an annual flush, helps the new unit last.

What the install includes

A proper install adds a drain pan or a floor drain, a relief valve with a discharge pipe, a shutoff valve, flexible connectors and an expansion tank where the code asks for one. Gas units need a sediment trap and a venting check.

The old tank is drained, disconnected and hauled away. Ask whether that is included, and whether the contractor pulls the permit and arranges the inspection.

Permits and code

The City of Lafayette Building Division enforces the 2024 I-Codes, which include the Plumbing, Mechanical and Fuel Gas Codes. A replacement often needs a permit, and the inspector checks the venting, the relief valve and the gas connection.

Ask the contractor to confirm who pulls the permit. An unpermitted install can cause trouble with an insurer or at the sale of the house.

Planning for the old tank

Ask whether the contractor will drain and haul away the old heater. Sediment can make it heavy, and the drain valve may be clogged. In a basement, the crew may need a path out for the old unit and a path in for the new one.

Take a photo of the area before work starts and measure the doorway. A large new tank may not fit through a narrow basement door.

Common questions

Answers on Water heater replacement

A standard swap is often a half day. A conversion to a different fuel or a new vent path takes longer.

That hinges on hot water demand, gas line size and budget. Read the tankless page, then ask the contractor to compare.

Many installations do, particularly with a closed system. The contractor will check the code.

Yes, but plan ahead. A leak in an occupied basement can damage finished space quickly.

Ring whenever. A dead tank frequently gets replaced in one trip, though what is possible depends on the contractor's inventory and calendar.
