Finnex HMC-50S 50 W Titanium Aquarium Heater
Model: Finnex HMC-50S Titanium Aquarium Heater, 50 W
This entry concerns the HMC-50S row in Finnex’s official US-facing family page checked 2026-11-01. The table identifies its 50 W rating, 10–20 US-gallon range, 6-inch tube and 0.45 A at a 110 V reference. The saved grouped Shop record lists 100/200/300/500 W options and no 50 W variant, so exact retail SKU/UPC/variant and package remain unverified. This is not a current offer or questionnaire-fit confirmation.
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-50S image was verified. The shared Shop gallery is HMU-labelled and has no HMC-50S wattage/package identity, so this model-reference page is text-only.
Finnex lists the HMC-50S as a 50 W configuration for 10–20 US gallons, with a 6-inch tube, 0.45 A at 110 V and a 68–92°F range. Although the model is named in the family table, the checked Shop options omitted 50 W and the finder cannot enforce the 10-gallon minimum.

Documented model details
- The individual HMC-50S row is 50 W for 10–20 US gallons, with a 6-inch tube, 0.45 A at 110 V and a 68–92°F control range. The lower size endpoint is part of Finnex’s published band, not an “up to 20 gallons” rating.
- Finnex’s HMC family text describes an adjustable digital display, remote sensor and memory of the last selected setting following an interruption, plus titanium construction, a guard and freshwater/marine and submersible use. These claims are not independent tests.
- The checked grouped Shop options were 100/200/300/500 W; the product handle’s “50” does not itself establish a 50 W variant. The manufacturer table still supports HMC-50S as a named configuration, but not as a verified Shop offer.
Limits to weigh
- The 10-gallon minimum is not enforceable by the current maximum-only finder, so HMC-50S remains outside ordinary recommendations even when a tank lies within the printed band.
- The 0.45 A value is only at 110 V; full supply voltage/frequency and the specific unit label are unknown.
- The current instructions index inspected for this edition did not list an HMC manual. Immersion depth, waterline, orientation, mounting, dry-operation and clearance directions remain unresolved.
- The reviewed Shop record did not expose a 50 W variant, leaving exact SKU, UPC, product offer and seller package unverified. The central route is a model search, not an exact listing.
- No HMC-50S-specific photograph was verified. The shared HMU-labelled gallery does not identify the 50 W HMC assembly or package; this reference lookup is text-only.
Check before ordering
- Confirm the exact model and wattage on the package: HMC-50S / 50 W, not the HMC-100S or another sibling.
- Treat Finnex’s 10–20 US-gallon band as two-sided. This reference is not a recommendation for tanks below 10 gallons or a fit approval for an individual tank.
- Check the exact heater’s full voltage/frequency label and supplied HMC instructions; the 110 V amperage value and family-level submersible wording do not settle electrical or installation compatibility.
- Verify the seller’s actual model, controller/probe/accessories, return terms and delivered package. A family table is not evidence of a current 50 W offer.
- The central destination is a full-model search, not a verified HMC-50S Amazon listing or exact package. Do not rely on the URL handle or a shared HMU image as identity proof.
