Hot Water Brief publishes researched price ranges for water heater replacement and repair across the United States. It is not a plumbing contractor, employs no installers and performs no work of any kind. Nothing on this site is a quote, and no page here can tell you what your own job will cost, only what the published national ranges say and where those figures came from.
Four topic hubs cover what replacement costs, what the common failures mean, what to do when there is no hot water or a tank is leaking, and the full buying decision. Underneath them sit individual guides on single questions, a page for each US state, and metro pages where local search demand is real. Every one of them is written to the same sourcing rule.
Published installer rate cards that stamp their own pages with a month, the US Department of Energy efficiency standards, Energy Star product data, the Code of Federal Regulations, and manufacturers' own manuals and warranty documents. Every figure carries the publisher and the date. If a fact cannot be traced that way it does not go on the page.
Federal minimum efficiency standards for consumer water heaters have been revised and equipment prices moved with them. A cost figure with no year attached cannot be checked and should not be trusted. That is the whole reason the dates are printed next to the numbers rather than buried in a footer: so you can see how old a figure is and judge it accordingly.
No response-time promise, no availability claim, and no assertion about what your price or outcome will be, because this site is not in a position to keep any of them. Where the honest answer is that it depends, the page says what it depends on rather than picking a number that reads well.
Sources get updated and prices move. If a figure here no longer matches its source, or the source itself has moved or gone, that is worth reporting and it gets fixed. Corrections to a sourced number are the one kind of feedback this site acts on quickly.
