How the estimate works
Each option maps to a costed product in our dataset, and the calculator renders that product's installed range — equipment plus labor, per the unit definition shown with the result. Add the expansion-tank toggle only where your municipality requires one; it adds the dataset's single-publisher band on top rather than folding it into the base figure. Nothing is scaled, inflated, or invented: when a row is derived or carries lower confidence, the flag travels with it.
What these national bands can't do: price your local labor market, quote a permit in your jurisdiction, or predict what code-required upgrades (pan, strapping, expansion tank) your inspection will demand. Get local written quotes before budgeting.
