Model reference
Finnex STE-200 digital titanium aquarium heater
Model: STE-200 / 200 W
This reference follows the 200 W / STE-200 option in Finnex’s US Shop selector and its separate STE-200 specification row; the series comparison supplies shared control and protection claims. The retailer photograph is used only as an identity cue. These materials do not establish a marketplace seller’s current offer or delivered package, complete voltage/frequency input, or the exact immersion procedure, and they do not assess a visitor’s questionnaire answers.
This model lookup is separate from the questionnaire shortlist. It does not certify that this model meets your selected requirements.

Finnex identifies the STE-200 as a 200 W controller-equipped titanium variant for a published 40–60 US-gallon band, with adjustable 68–92°F digital control. The site cannot enforce that 40-gallon floor, and the reviewed sources leave complete electrical and installation details open, so this is a model-reference lookup rather than a tank-fit recommendation.

Documented model details
- Finnex’s variant data pairs STE-200 with 200 W, SKU STE-200 and UPC 850006562411. The model graphic lists 40–60 US gallons, 68–92°F, 1.67 A without an amperage reference voltage, and one-degree setting increments.
- Finnex describes the STE as a digital controller with a remote aquarium-water sensor, titanium tube, nickel coil and heater guard, and states freshwater/marine use. The series chart lists a non-resumable out-of-water-protection fuse and ETL/UL-standard listing; these are manufacturer descriptions, not independent testing.
- The 40-gallon lower endpoint is distinct from the 60-gallon ceiling. It cannot be honored by the current maximum-only volume rule, so the model remains outside ordinary finder recommendations.
Limits to weigh
- The current matcher cannot enforce the manufacturer’s 40-gallon minimum. This reference does not determine whether the STE-200 fits a specific aquarium or target temperature.
- Finnex lists 1.67 A but the reviewed graphic gives no voltage basis; complete supply voltage/frequency and nameplate requirements remain unverified.
- The reviewed sources do not provide this model’s exact immersion depth, orientation, clearance, dry-operation procedure or full setup instructions. A remote sensor and protection claims do not supply those missing directions.
- The retailer image identifies an STE-200 / 200 W carton beside a guarded element and controller, but it does not establish a current marketplace offer, shipped package contents or installation.
Check before ordering
- Confirm the product and carton identify Finnex STE-200 / 200 W; the documented Shop variant is SKU STE-200 / UPC 850006562411. Do not substitute another STE wattage or a different Finnex heater family.
- Compare the tank with the full 40–60 US-gallon maker band, including its 40-gallon lower limit. This reference is not a questionnaire-validated fit.
- Verify the exact package includes the intended controller, sensor and guard; do not infer the seller’s contents from the identity photograph.
- Read the actual heater and controller labels for complete electrical input, and obtain the exact installation instructions for immersion, orientation and clearance before use.
- If using the model-search action, verify the listing’s brand, full model, wattage, seller, condition and included parts; the search is not an exact listing match.
