Finnex HMU-100S 100 W Digital Titanium Aquarium Heater
Model: Finnex HMU-100S Digital Titanium Aquarium Heater, 100 W
This follows the 100 W HMU-100S variant in Finnex's grouped US Shop record and the HMU range on its titanium-heater comparison chart. The Shop variant identifies its own SKU and Shopify variant ID but no barcode. The chart's shared claims apply to the 100–500 W HMU span; the reviewed records do not establish tank volume, complete electrical input, approved water type or installation instructions for this exact configuration. Neither this source scope nor the model reference confirms a seller's offer or delivered package.
This model lookup is separate from the questionnaire shortlist. It does not certify that this model meets your selected requirements.
Exact-model photograph is not verified. Text-only reference page. The reviewed official HMU image is a shared family visual, not an exact HMU-100S wattage or package photograph, so it is not presented as this selected assembly.
Finnex's exact Shop option identifies HMU-100S at 100 W, while its series chart gives the 100–500 W HMU range as 68–92°F. The reviewed manufacturer sources give no aquarium-capacity rating, so this is a model-identification lookup, not a tank-fit recommendation.

Documented model details
- The official Shop variant row identifies 100 Watts, SKU HMU-100S and its own Shopify variant ID, 49216058949931. Its barcode field is blank, so no UPC is assigned.
- Finnex's comparison chart covers HMU variants from 100 to 500 W and lists a 68–92°F control range, push control, digital display, titanium heating tube, steel coil and a non-resumable fuse. These are maker-stated series claims, not independent performance or safety testing.
- The grouped HMU Shop description names a remote temperature sensor and a flame-retardant heater guard alongside the digital controller/display. This describes Finnex's family page, not proof of a seller's current package contents.
Limits to weigh
- No reviewed official source gives HMU-100S an aquarium-capacity range. Wattage alone does not establish a suitable tank size or heating performance.
- The reviewed primary sources do not establish this variant's complete voltage/frequency rating, approved freshwater or saltwater use, installation/submersion requirements, clearance or dimensions. The current instructions index lists other heater-series manuals but no HMU manual; their directions are not transferred.
- The product record has no UPC, and Finnex's grouped gallery visual does not identify the selected HMU-100S assembly or retail package. This model-reference lookup does not certify an exact Amazon listing, seller package or questionnaire compatibility.
Check before ordering
- Check the offered heater and its label for the exact HMU-100S model/SKU and 100 W rating; do not substitute HMU-50S or another wattage.
- Verify the actual unit's complete voltage/frequency label and regional electrical compatibility; the US Shop record and chart do not supply a full nameplate rating.
- Before installation, obtain exact-model documentation for tank capacity, water type, immersion, orientation and clearance. Do not convert 100 W into a gallon recommendation.
- Compare the seller's stated package with the actual offer, including any controller, remote sensor and guard. The manufacturer family description does not prove which parts a seller ships; use an independent thermometer to check aquarium water after setup.
