Aqueon Preset Heater 100 W

Exact-model photograph is not verified. The exact UPC-linked package photo remains in the detailed review at assets-source/products/images/aqueon-preset-100w-package.jpg (SHA-256 189e10f4e69f294641ae4b34ece7634338b04079f8681d86ec113367af0b83f9); it reads up to 20 gallons. This separate reference page stays text-only because the adapter only accepts a directly mapped root-level original image. The photo identifies the pictured package, not seller stock, scale, fit or delivered contents.

The Aqueon US Preset Heater 100 W is PS100H, Item 100106252 / UPC 015905062527. Its manual recommends 20-30 gallons and its selector/table cap at 30, but official package depictions carry different labels; because the matcher cannot enforce the 20-gallon floor, this is a model-reference lookup, not a finder fit.

Confirm the exact model, package quantity, condition, included parts and current seller terms before ordering.

Documented model details

• Aqueon's 100 W selector record and 2025 US catalog table identify Item 100106252 / UPC 015905062527; the exact PS100H manual names the 100 W model and specifies 120 V / 60 Hz.
• The PS100H manual recommends 20-30 US gallons. The selector record and 2025 catalog table give an up-to-30 maximum. Separately, the exact UPC-linked product-page package photo reads up to 20 gallons, the 100 W package illustration on the 2025 catalog spread reads up to 40, and Aqueon's general 100 W chart spans 15-40. These are distinct maker statements, not a single agreed capacity range.
• The selector record describes a fixed 78-degree F preset, stated +/-1-degree accuracy, no adjustment, a red lamp while heating, shatter-resistant quartz glass, full submersion and an automatic safety shut-off. These are manufacturer descriptions, not independent measurements or livestock-temperature advice.
• The exact manual specifies one suction cup for the 100 W model; vertical placement must keep water above the marked minimum line, while horizontal placement must remain fully submerged. It calls for adequate circulation, the rubber bottom guard and a 30-minute submerged wait before power; it forbids dry operation.
• The manual lists 5.5 inches overall length. The selector's 3.5 x 1.5 x 7.75-inch dimensions match the catalog's retail-package tuple; neither should be treated as installed clearance.

Limits to weigh

• This model stays outside the finder and purchase shortlist because the current max-only tank-volume rule cannot enforce the exact manual's 20-gallon minimum; it would otherwise expose the heater below its stated range.
• Capacity wording differs by source: manual 20-30 and selector/table maximum 30; exact product-page package photo up to 20; separate catalog package illustration up to 40; generic 100 W chart 15-40. Do not average these figures or infer which package a seller ships.
• The preset and stated accuracy do not show actual temperature throughout a tank or establish the right temperature for a species. Verify water independently and follow appropriate care guidance.
• The listed package-like dimensions are not mounting clearance. The reviewed materials do not establish a seller's current inventory or supplied condition; check the exact offered box, electrical label and instructions.

Check before ordering

• If evaluating a separately found offer, match Aqueon Preset Heater 100 W / PS100H / Item 100106252 / UPC 015905062527; do not substitute another wattage. Inspect the offered box and included instructions because official package depictions differ.
• Use the PS100H manual's 20-30-gallon recommendation as the model-specific band; preserve the separate up-to-20 and up-to-40 package labels and the table's up-to-30 ceiling rather than averaging them. This page is not a finder-approved fit.
• Confirm the actual unit's 120 V / 60 Hz supply label, one-cup placement, marked minimum waterline, rubber bottom guard and water circulation. Follow the manual's 30-minute submerged wait, drip-loop precautions and unplug-before-service rule; never run it dry.
• Allow physical space using the manual's stated 5.5-inch overall length as a reference, not the retail-package dimensions. Check the actual unit, mounting position and cord route.
• Because 78 degrees F is fixed, compare that preset with the animals' appropriate temperature needs and use an independent aquarium thermometer; the maker's +/-1-degree accuracy statement is not a measured whole-tank result.
