Water heater replacement cost

By type

Start with the kind of heater you are replacing or considering. The standard tank row combines gas and electric figures; Fixr's contribution covers gas tanks only. Tankless and hybrid heat pump figures come from Angi and HomeGuide. These installed ranges are broad comparisons, rather than a promise that different systems can be swapped at the same price.

Installed costs, with the source figures combined using the median rule. A typical figure can use a publisher's stated average, so it need not sit exactly halfway between the ends of the range.

By tank size

If you know your tank size, use its row as a more specific starting point. The size figures come from the same published guides, but they are not a separate charge to add to the type price. In the estimator, choosing a tank size replaces the standard tank starting range. Leave it at Not sure if the capacity has not been confirmed.

Tank sizes only. These are alternative installed starting ranges, not extras. Publisher-specific figures and notes remain available below without rounding.

What adds to the price

Ask which of these items are included in a quote before adding them to your budget. Published guides list them separately, and the estimator adds selected extras in full. For example, a permit has a typical figure of $175, while removal and disposal runs from $100 to $500. Not every job needs every item, and the available choices depend on the heater type.

Additional work only. Applies to shows which heater types the dataset associates with each item; it does not establish that your job needs it.

Labor

These are the publishers' original labor figures, shown for context rather than added to the installed ranges. The hourly plumber figures are rates, not a total for the job. Keep labor inside the replacement price when comparing quotes, and ask whether separately listed work is already covered. The estimator does not add any of the labor rows below.

Informational only. Already inside the installed ranges above.

Running costs and incentives

Installation and running costs are different parts of the decision. HomeGuide supplies the yearly running-cost figures below; the Department of Energy supplies the heat pump efficiency and space guidance. The water-line and panel costs are context, not selectable estimator extras. Check the dated federal-credit information separately rather than subtracting a credit from a current installation estimate.

Estimate your replacement

Choose the heater type and any known tank size, then add only the work you expect to need. The result starts with the sourced installed range and follows the assumptions listed underneath. It does not check your home's layout, fuel supply or local requirements. Use it to frame questions for a contractor, not to replace a written assessment.

Where these numbers come from

The figures come from the linked publishers, with each guide's update and access dates shown below. Open the source details under a table to compare the original amounts with the combined figures. Source scopes are not identical: the Fixr guide concerns gas tank-style heaters. The checked date records when this dataset was reviewed, not when a contractor priced your home.

For each row, the middle of the published low figures becomes the low, and the middle of the high figures becomes the high. With an even number of figures, the middle is the average of the central pair. Typical uses the middle of stated averages when any are available; otherwise it uses the middle of each source's range midpoint. Below a thousand dollars, rounding uses twenty-five-dollar steps; at or above a thousand dollars, it uses fifty-dollar steps. Exact halfway amounts round up. Original source figures stay unchanged, and estimator totals are rounded only after selected extras are added.

Questions people ask

What is a typical water heater replacement cost?

For a standard tank, the typical installed figure is $1,600 and the sourced range is $600 to $2,700. This combines the published figures using the median rule. A quote for your home may differ, so check the heater type, size and separately listed work before comparing it with this guide.

How much does a tankless water heater cost to install?

The sourced tankless installed range is $1,400 to $4,750, with a typical figure of $3,100. That is a different starting row from a tank replacement. The dataset also lists possible venting, gas-line and electrical work separately; confirm what applies and what is included in your quote.

Does the estimate include labor?

The starting rows are installed costs, so the informational labor figures are not added again. Selected extras are added in full under the estimator's assumptions. Ask a contractor to identify labor and additional work clearly so you do not count the same item twice.

What if I do not know my tank size?

Leave tank size at Not sure to use the standard tank row. If you confirm the size later, choosing it replaces that starting row rather than adding another price. The size table lets you compare the sourced installed figures before making that selection.

Can I subtract a federal heat pump credit from this estimate?

No federal credit is deducted here. The federal home energy credit for heat pump water heaters (30 percent, up to $2,000 a year) applied to property placed in service through December 31, 2025, and does not apply to installs after that date. The estimator shows installation costs and selected extras without incentives, so do not treat the earlier credit as a reduction for a current installation.

Treat this guide as a starting budget, then compare written local quotes for the same heater and scope of work. Keep the source dates, included items and any exclusions beside each quote. If a proposed job falls outside the choices shown here, ask for a separate explanation rather than stretching this estimate to cover it.
