Aqueon Submersible Glass Heater 100 W

Exact-model photograph is not verified. The full review shows the manufacturer’s exact 100 W / UPC 015905000307 package image. It identifies the package variant but does not establish an offered seller’s contents, installed dimensions or heater performance.

The TA100 is the 100 W Submersible Glass configuration identified by Item 100528586 / UPC 015905000307. Its exact manual recommends 15–40 US gallons, while Aqueon’s page, package and catalog agree on an upper rating of 40. Because the matcher cannot reject tanks below 15 gallons, this record identifies the model without presenting it as an eligible result.

Documented model details

• The current family selector and 2025 catalog identify the 100 W heater as Item 100528586 / UPC 015905000307; the shared manufacturer manual names the TA100 row.
• The TA100 manual recommends 15–40 US gallons. The exact package, current product page and catalog state an upper rating of 40 gallons, consistent at the ceiling but not a replacement for the manual’s lower limit.
• The family page describes a 68–88°F electronic adjustment range with 1°F setting steps, freshwater/saltwater use, an operating indicator, automatic shutoff when not properly submerged and shatter-resistant quartz glass. These are manufacturer claims, not independent performance or durability findings.
• The manual requires fully submerged in-tank installation and circulation, shows a marked minimum water line, calls for a 30-minute submerged wait before plugging in and says to wait 24 hours before adjusting the original setting.
• The manual gives 10.3 inches overall length. Catalog item dimensions are 1.375 × 1.375 × 10.325 inches, while its package is 3.75 × 1.5 × 10.75 inches. The product page’s separate dimensions are not defined as a body-clearance measure.

Limits to weigh

• The active volume rule uses a maximum-only comparison and cannot enforce the TA100’s 15-gallon lower recommendation; it is kept reference-only to avoid a small-tank false match.
• The page and package’s “up to 40 gallons” statement is an upper rating, not a lower limit or assurance that the heater will hold a specific temperature under a particular room and tank condition.
• Shatter-resistant quartz is not documented as shatterproof. The listed thermostat settings and shutoff claims are not independent tests.
• The full-review photo is an exact UPC package image, but the image does not verify a seller’s delivered package, measured installation clearance or operating result.

Check before ordering

• Confirm TA100, 100 W, Item 100528586 and UPC 015905000307 on the actual offer or carton; check the model number rather than choosing by wattage alone.
• Use the manual’s 15–40 US-gallon recommendation as the configuration-specific band and read the supplied instructions for the intended setup; the catalog ceiling alone is incomplete.
• Check the actual unit’s 120 V / 60 Hz label, available submerged mounting length, marked water line and circulation before purchase and installation.
• Follow the maker’s wait and adjustment instructions and monitor actual aquarium water with an independent thermometer; do not interpret a maker-stated setting increment as tested accuracy.
