About Heater Handbook

Heater Handbook publishes practical guides to the water heater in a house: storage tanks, tankless heaters, gas and electric fuel, heat pump water heaters, and the failures that show up as cold showers, wet floors, noises, smells, and error codes. The byline on every guide is the Heater Handbook editorial team. There is no roster of named plumbers, no stock portrait, and no review written in a customer’s voice. Those devices make a thin site look occupied. They are not used here.

What the site is for

A useful page answers a question a person can check against their own heater. How a dip tube fails. Why the upper electric element can leave a tank completely cold while a dead lower element only shortens the shower. Why a temperature-and-pressure valve weeps on a closed plumbing system. What first-hour rating means on the yellow label, and why a gallon count does not. What a published cost range includes, and what a local quote still has to add.

The site is organized as five sections. Types separates the machines. Troubleshooting starts from the symptom. Maintenance is the small set of jobs that actually change how long a tank or a heat exchanger lasts. Sizing, buying, and cost is for the replacement decision. Safety and calling a pro is the boundary: gas, venting, electrical work, scalding, permits, and the moment to stop.

Guides link to each other where the jobs touch. A noise page does not repeat a flush procedure. It tells you the sound sediment makes and sends you to the flush. That split is deliberate. Repeating the same eight hundred words under a new title is how a site gets rejected as low-value content, and it is also how a reader gets a procedure that was written for a different appliance.

What the site will not do

Heater Handbook does not sell heaters, parts, or leads. This version has no affiliate links and no “best model” ranking that exists to pay for itself. Manufacturer sites are linked where you need a manual for a model number, because the manual is the controlling document for that unit. A link to a support library is not an endorsement and not a place to buy.

The site does not dispatch a technician, give a price for your house, or pull a permit. It does not diagnose carbon monoxide from a paragraph. If you smell gas, or an alarm is sounding, the right action is to leave and call the gas utility or the emergency number, which is stated on the safety pages and in the disclaimer. Email is not an emergency line.

Licensing is local. In many places a homeowner may work on a house they live in, and in many of those same places they may not touch the gas piping, the flue, or a rental unit. The guides do not pretend there is one national DIY statute. They mark the tasks that stay dangerous even where the law allows them: live 240-volt equipment, combustion, refrigerant, and any repair that defeats a relief valve.

How the pages are made

Guides are written against public primary sources and then edited so a step is either doable or explicitly handed to a licensed trade. The sources you will see most often are the U.S. Department of Energy’s Energy Saver material, the ENERGY STAR water-heater pages, the U.S. Consumer Product Safety Commission’s tap-water scald publication, Centers for Disease Control and Prevention material on Legionella in building water, the Internal Revenue Service pages on the energy-efficient home improvement credit, ICC explanations of relief-valve discharge rules, and installation manuals from the major manufacturers.

Where those sources disagree, the page says so. The clearest example is air space around a heat pump water heater. A Department of Energy consumer article has said the unit needs at least 1,000 cubic feet and a room that stays between 40°F and 90°F. An ENERGY STAR note to contractors has described a lower minimum, about 450 cubic feet, and told readers to follow the model’s own specification because manufacturers differ. The heat pump guide reports both and tells you the installation manual is what an inspector will use. Smoothing that into a single fake number would read more smoothly and be worse.

Cost figures are typical ranges from a named source and a named year. They are not quotes. The federal credit for heat pump water heaters is described the way the IRS describes it: property placed in service after December 31, 2025 does not qualify. Older articles on the web still subtract that credit from a 2026 installation. This site does not.

Corrections

A model year changes a status-light code. A city amends the mechanical code. A published price survey moves. If a guide is wrong, the contact page explains what to send: the URL, the sentence, and the better source. Corrections are how the date at the top of a page earns its keep. The editorial policy is the longer account of sourcing, advertising, and what the desk will not publish.

Advertising

The pages carry the Google AdSense account meta tag and an ads.txt file so the site can be reviewed. The automatic-ad script is present only as an HTML comment and does not load. There are no empty boxes labeled as advertisements. If the site is later approved and the script is turned on, the privacy policy is the place that explains Google’s cookies. Advertising does not choose which failure mode a guide calls a tank leak.

Heater Handbook is not a plumbing company, a public utility, or a government program. It is an editorial project with a contact email and a narrow subject. The work is the guides.
