Finnex HMH-200S 200 W Digital Titanium Aquarium Heater
Model: Finnex HMH-200S 200 W Digital Titanium Aquarium Heater (manual-defined configuration; retail SKU unverified)
This entry concerns the separately named HMH-200S row in Finnex’s official HMH manual checked 2026-11-01. It gives 200 W, 60–80 US gallons, 1.80 A at a 115 V reference, 50–94°F control, an 11.61-inch tube, and 55/35.4/47-inch power/controller/sensor leads. The official Shop collection and HMH search, both checked 2026-11-01, did not resolve an individual variant, retail SKU, UPC, package, or present offer. Neither the full voltage/frequency nameplate nor fit for a particular tank is established.
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 wattage-specific HMH product or package photograph was verified. The official HMH family artwork and manual diagram identify a series, not this selected model or delivered package; this model-reference entry is text-only.
The manual lists HMH-200S at 200 W for 60–80 US gallons, with an 11.61-inch tube and a 35.4-inch controller lead. Its 80-gallon endpoint is also the start of the 300 W row; because the finder cannot enforce the lower bound, this remains an identity reference rather than a recommendation.

Documented model details
- The manual assigns the HMH-200S a 60–80 US-gallon band. At 11.61 inches, its tube is substantially longer than the 150 W row’s 8.86 inches; its power, controller-to-heater and sensor cords are 55, 35.4 and 47 inches.
- The controller range is 50–94°F with 0.1°F adjustment and a stated ±0.5°F display accuracy. HMH senses temperature inside the heater tube; its sensor-position instructions differ from the remote probe on the HMS family.
- The HMH family page and manual describe titanium, a protective guard, freshwater/marine use conditioned on water above 150 ppm TDS, fully submerged placement and a low-water warning system whose stated operating range is 58–92°F.
Limits to weigh
- The 60-gallon lower bound is not enforceable by the finder. The 80-gallon upper edge is also the 300 W HMH-300S lower edge; this page does not adjudicate the overlap or certify heat-load suitability.
- The 1.80 A figure is referenced to 115 V only. Full accepted voltage/frequency, the exact item label, retail SKU/UPC, included set and current seller package were not verified in the checked official Shop collection/search.
- The HMH manual says its low-water warning is disabled outside 58–92°F and warns that the heater can continue heating while the sensor is exposed beyond that range. Do not assume it is a general dry-run cutout.
- The manufacturer’s >150 ppm TDS condition is absent from the questionnaire. No HMH-200S-specific product/package photograph was confirmed; family graphics and manual drawings do not identify this exact wattage package.
Check before ordering
- Match the actual unit and carton to HMH-200S / 200 W; a listing for HMH-150S or HMH-300S is not equivalent.
- Check both limits, 60–80 US gallons. At exactly 80 gallons, HMH-300S also begins; the shared endpoint is not a recommendation to use either heater without evaluating the aquarium and conditions.
- Read the complete electrical label and the supplied HMH instructions. Treat 1.80 A at 115 V as a reference point, not the full input rating; confirm package, seller and all included pieces.
- Follow the maker’s fully submerged, circulation, built-in sensor elevation, acclimation, drip-loop/GFCI and cleaning directions. Verify the >150 ppm TDS condition and understand the 58–92°F low-water warning limit.
