As of 9 November 2026, Water Heater Handbook has published no corrections. When we get something wrong, we fix the page and record the fix here, with the date, the page and what changed. Found an error? Here is how to report it.
General information, not professional advice. Gas, 240-volt power, scalding water and a pressurised tank can hurt you. Follow the label and manual on your own heater; where they say to stop and call a qualified technician, stop. Codes and licensing rules are set locally.
An empty log does not mean our pages are free of mistakes. It means no error has been corrected yet. Makers revise their manuals, federal efficiency standards and ENERGY STAR criteria change, model codes come out in new editions, and energy prices move every year. Each page gets a fact-check against its sources, as our editorial policy explains, but no check catches everything.

What counts as a correction
A correction is a change to something a page got wrong, such as a step, the order of steps, a caution or stop point left out or put in the wrong place, which maker or document a step comes from, a temperature, a pressure, an interval, a size, an electrical figure, an efficiency rating, a federal standard or its effective date, a code section or edition, a serial number format, an error code meaning, an energy price, a citation, a read date, a sum or a calculator result. It also covers a page that stayed unchanged after its source moved on, leaving a reader with an out-of-date step or figure.
Routine work is not logged here. That means fixing a typo or a broken link, adding a new section, adding a maker’s document we have newly read, or our scheduled rechecks, as our how we check page describes. A page shows an updated date only when its content really changed.
How we correct an error
- We check the claim against its source, such as the maker’s manual by part number and date, the federal rule in the eCFR, a CPSC, CDC, EPA, PHMSA, DOE, ENERGY STAR, EIA or IRS page, or the model code section and edition, and rework any sum it affects.
- If the page is wrong, we fix it, along with any other page, table, graphic or calculator that uses the same step or figure, and show the new updated date. An error in a gas, electrical, relief valve, temperature or carbon monoxide step is fixed first.
- We add an entry to the log above with the date, a link to the page, what it said and what it says now.
If the source does not settle the question, we remove the step or figure, or say plainly that it is not confirmed. If the source supports the page as written, the page stays as it is. Advertisers have no say over what we publish, so a report from a maker, a retailer, a contractor or an advertiser is checked the same way as any other.
How to report an error
Use our contact page or email contact@waterheaterhandbook.com, and include:
- the address of the page
- the step, sentence, figure or calculator result you think is wrong
- a link to the maker’s manual (with its part number and date), the federal rule or the code section that shows the right answer, if you have one
Please leave out details of your own heater and home. We can’t diagnose a heater, say whether a repair is within your skills or recommend plumbers, installers or products. Our pages are general information, as our disclaimer sets out. If you smell gas, don’t write to us: leave the building and call 911 or your gas utility from outside.
