Finnex HMC-200S 200 W Titanium Aquarium Heater

Exact-model photograph is not verified. Text-only reference entry. The existing ordinary review keeps an official HMC-family component image whose caption says the wattage and element length are not identified; it is not an exact HMC-200S or package photograph and is not reproduced here. No exact wattage-specific photo is verified.

Finnex assigns the HMC-200S 200 W, a 40–60 US-gallon band, an 11.2-inch element and 68–92°F control. Its official Shop option has the HMC-200S SKU, while the meaningful 40-gallon floor and incomplete electrical/setup details keep this an identification reference rather than a fit recommendation.

Documented model details

• The exact family-table row is HMC-200S, 200 W, 40–60 US gallons, 11.2 inches, 1.67 A at the stated 110 V reference, and a 68–92°F control range.
• The 40-gallon lower limit is material: the adjacent HMC-100S is listed for 20–30 gallons, while HMC-300S is listed for 60–80 gallons. The HMC-200S and HMC-300S ranges meet at 60 gallons; do not interpolate a model for the gap above 30 and below 40 gallons or treat a maximum alone as a match.
• Finnex describes the HMC controller as an illuminated external digital display with adjustment, a remote temperature sensor and memory that restores the previous setting after a power interruption. These are manufacturer descriptions, not measured accuracy, temperature stability or response-time findings.
• The HMC family is described as using a titanium heating element with a protective flame-retardant guard and as suitable for freshwater and marine aquariums. Finnex labels the family submersible, but the reviewed model material does not establish detailed installation directions or prove a specific seller package.
• The grouped official Shop record includes a separate 200 W option with SKU HMC-200S and Shopify variant ID 51471028420907; its barcode is null. That supports the exact model/option cross-check, not a current third-party listing, package or stock claim.
• The HMC family component image shows shared parts rather than a wattage-marked HMC-200S unit. No exact 200 W element or package is established by those pixels.

Limits to weigh

• The published 40–60 US-gallon band is a maker-stated sizing suggestion, not a guarantee for a particular room temperature, aquarium heat loss, target or installation. Its lower boundary must not be silently dropped.
• The 1.67 A figure is expressly tied to the table’s 110 V reference. The reviewed sources do not specify the full permitted voltage range or frequency for this exact configuration.
• The saved Finnex instructions index lists HMH, HMS and HPC manuals but no HMC entry. That index observation does not prove an HMC manual does not exist; waterline, minimum immersion, orientation, mounting, sensor position and inline-filter use remain unverified here.
• The Shop variant has a null barcode. Neither it nor the manufacturer family table establishes a particular US third-party offer, exact delivered package, seller, stock state or included contents for that offer.
• No exact HMC-200S wattage/package photograph is verified. The ordinary review uses an officially associated HMC-family visual with a family-only caption; this reference entry is text-only.
• The existing exact-model Amazon.com US attempt returned HTTP 503 before listing identity or package details could be inspected. No exact Amazon listing is established; this blocked access is not evidence that no listing exists.

Check before ordering

• Check the physical unit and carton for the exact Finnex HMC-200S / 200 W identity; do not substitute the HMC-100S, HMC-300S or a different 200 W heater.
• Compare the complete 40–60 US-gallon manufacturer band with the actual aquarium and its heat-loss conditions. Do not use a tank below 40 gallons on the basis of the 60-gallon ceiling or infer a heating guarantee from wattage.
• Read the actual unit’s complete voltage and frequency label before connection. The 1.67 A figure is only the manufacturer table’s 110 V reference, not a substitute for the nameplate.
• Request the current HMC-specific instructions and confirm safe immersion, waterline, mounting, clearance and remote-sensor placement. Do not transfer HMH, HMS or HPC setup steps to HMC.
• Confirm what the exact seller offer includes—controller, remote sensor, guard and heater—rather than treating shared family copy or a generic component image as proof of a particular package.
• Treat any unverified destination as a search for the full HMC-200S model, not a confirmed listing. Verify the listing and delivered item against the exact code before purchase; do not accept a sibling model as equivalent.
