Finnex HMC-400S 400 W Titanium Aquarium Heater
Model: Finnex HMC-400S Titanium Aquarium Heater, 400 W
This is the HMC-400S configuration named in Finnex’s official US-facing family table checked 2026-11-01. That table identifies the wattage, two-sided gallon range, tube length and 110 V amperage reference. In the saved grouped Shop record, the listed options were 100/200/300/500 W, with no 400 W variant; no HMC-400S retail SKU, UPC, variant or package was established. This lookup does not certify a current seller or questionnaire compatibility.
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. No exact HMC-400S product photograph was verified. The official family page’s placeholder artwork and the grouped Shop’s shared HMU-labelled images are not this model’s product/package photo; the reference lookup is text-only.
Finnex’s HMC family table identifies a 400 W HMC-400S row for 80–100 US gallons, with a 15.1-inch tube, 3.33 A at 110 V and a 68–92°F control range. The checked Shop selector did not list 400 W, and the finder cannot enforce the 80-gallon minimum; this is an identity reference, not a recommendation.

Documented model details
- The individually named HMC-400S row lists 400 W, 80–100 US gallons, 15.1 inches, 3.33 A at the table’s 110 V reference and a 68–92°F control span.
- The HMC family description includes an adjustable illuminated digital controller, remote temperature sensor, stored-setting memory, titanium heater element, guard, and freshwater/marine and submersible claims. These are manufacturer statements, not independently measured accuracy, safety or temperature stability.
- Finnex’s captured Shop selector omits a 400 W option even though the family table names HMC-400S. The table establishes a manufacturer model row; it does not fill in the missing Shop SKU/UPC or identify an individual retail offer.
Limits to weigh
- Finnex’s 80-gallon lower bound cannot be applied by the maximum-only finder, so the HMC-400S has no ordinary finder recommendation or questionnaire-based purchase route.
- The 3.33 A entry is referenced to 110 V; the full allowed voltage/frequency and exact unit nameplate remain unverified.
- The inspected manufacturer instructions index did not expose an HMC manual. Full placement, immersion, waterline, dry-operation and clearance directions are not established.
- The saved Shop selector omitted 400 W, leaving SKU, UPC, variant, retail package and current offer identity unresolved. The fixed central search is not an exact listing confirmation.
- No exact HMC-400S photo was verified. The shared HMU-labelled Shop assets and family-page placeholders do not identify this specific wattage/package; the reference page is text-only.
Check before ordering
- Require the actual item or package to identify HMC-400S / 400 W; do not accept a generic “Finnex digital titanium heater” description as exact identity.
- Read the 80–100 US-gallon band with its lower and upper limits; this lookup does not approve fit at either boundary.
- Inspect the exact power label and supplied HMC instructions for voltage, frequency and installation before use; 3.33 A at 110 V is not a complete supply specification.
- Confirm the exact seller, package and included parts before ordering. The checked Shop selector did not expose a 400 W variant and does not establish third-party inventory.
- The central action is a full-model search, not a verified HMC-400S ASIN or offer. Do not substitute an HMC-300S/HMC-500S package or HMU-family image.
