How we work

BayHeat sizes heaters with the same model on every page, cites the number behind every claim, and says plainly when something isn't confirmed yet. These seven pledges are how we hold that line.

Seven pledges

1. Open model. The heat-loss and circuit-sizing calculations that size your garage run live on the page you're reading, not a table we typed in once and forgot to update.
2. Cite everything. A number that isn't computed live carries a source — a manufacturer manual, a code section, or a fuel-cost table. Click a number to see where it came from.
3. Never fabricate. If we're not confident in a figure, we mark it unverified and hide any sentence that depends on it, rather than publish a guess dressed up as a fact.
4. Disclose money clearly. A page with a paid link says so directly above that link, not in a footnote you have to hunt for.
5. Correct fast. Every page carries a revision number and a last-checked date in its Lab stamp, so you can see when something last changed.
6. A licensed reviewer checks electrical and gas rules. Code citations and circuit sizing are built from the published code text; a licensed electrician or gas technician signs off before a page is marked reviewed. See where that stands today, below.
7. No invented personas. We don't publish a byline for a person who doesn't exist. Until a named editor is posted, the byline reads "BayHeat editorial desk."

How BayHeat makes money

BayHeat is free to read. We earn a commission when you buy a heater through a link on the site — as an Amazon Associate, and through a small number of other retailer and installer-quote partners. The price you pay doesn't change either way.

That commission never decides which heater we recommend or what a verdict says. The sizing math runs the same way whether or not a class has a paid link attached, and every page names at least one thing not to buy alongside what to buy.

Who checks each page

Every page opens with a Lab stamp: a small expandable line naming its revision, its last-checked date, and the model version behind its numbers. Opening it shows a sentence built the same way on every page. Today, on a page that makes no electrical or gas claim, it reads:

A page that states an electrical or gas code rule shows a second line. Today, most of those read:

That's accurate, not a placeholder — no licensed electrician or gas technician has signed off on BayHeat's pages yet. As reviewers come on board, their name, license number, state, and the date they verified the page replace that line. You'll never see a review claimed before it happened.

More on who publishes BayHeat is on the about page. What we collect from your visit (very little) is on the privacy page.
