Moderate evidence confidence
Moderate evidence confidence is an internal CostMage evidence-quality score (61 of 100). It describes source strength and extract completeness, not the probability that a quoted figure matches your bill.
Labels: 75–100 high, 60–74 moderate, below 60 limited. The number is not a probability that the cost is correct.
Where a quote sits
Type an amount you were given. The page says whether it is below, inside, or above each published band. The middle of a band is not labeled a typical price.

Questions
What does replacement cost installed?
CostMage does not have a defensible installed national typical. Only equipment observations are shown.
Are the Home Depot prices a national average?
No. They are two listed 50-gal gas SKUs captured on 2026-09-06.
Where is installation labor?
Not sourced as a defensible national typical on this page. See the heat-pump water heater page for a separate informal labor envelope that still is not added here.
