Finnex TH-800S 800 W Titanium Heater Element
Model: Finnex TH-800S titanium aquarium heater element, 800 W
Finnex’s US Shop selector offers an 800 W TH tube-only option; its family table labels it TH-800S, while the separate HC-820M combo table uses TH-0800S. This entry is about the 800 W element only, not an asserted standalone retail package or exact seller offer. The sources do not establish a controller included with the tube, a full installation procedure or compatibility with any visitor’s questionnaire answers.
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. Text-only reference. Finnex’s grouped TH family photo is shared across 300/500/800 W options and does not identify a TH-800S-specific package or selected assembly.
The Finnex TH-800S is an 800 W tube listed for 140–265 US gallons, with a 16.5-inch body and a separate controller requirement. The 140-gallon floor cannot be represented by the finder, and the element is not a complete temperature-control package, so this is a reference lookup rather than a fit recommendation.

Documented model details
- Finnex lists TH-800S at 800 W, 120 V and 9.0 A, with a 140–265 US-gallon band and a tube 16.5 inches long by 0.75 inch in diameter. The family table’s 120 V and 9.0 A are separate fields; the combo table labels 9.0 A at 115 V for the zero-padded TH-0800S row.
- The TH Shop selector is explicitly for a titanium tube only, with the controller sold separately. Finnex’s separate HC-820M combo is a different package and the controller’s own manual specifications should not be transferred to an unspecified controller.
- Finnex describes the TH element and guard for freshwater and marine setups. Its official grouped photos show the TH family tube/guard but do not mark the 800 W selection.
Limits to weigh
- The listed 140–265-gallon band has a meaningful 140-gallon floor, which the current maximum-only finder cannot enforce. The model reference is not a recommendation for a smaller tank.
- Finnex’s family table places 120 V and 9.0 A in adjacent columns; its combo table labels 9.0 A at 115 V for TH-0800S. The current reference voltage is unresolved, and frequency/full supply details are absent.
- No standalone retail SKU/UPC, exact seller package or included temperature controller is established. The bare element requires a compatible separate controller.
- The reviewed sources do not provide the TH-800S’s immersion mark, orientation, clearance, dry-running limit or complete heater installation instructions. The controller manual is not an element manual.
- The shared official TH image does not identify 800 W, a model-specific package or selected assembly; this reference page is text-only.
Check before ordering
- Confirm the element label says TH-800S / 800 W; TH-0800S is the separate combo-table label, not an established retail SKU. Do not substitute a THD wattage or another power tier.
- Check the complete 140–265 US-gallon manufacturer band, including the 140-gallon lower endpoint; the finder cannot screen out below-band tanks.
- Confirm the exact controller, its connection and capacity for the element, and the seller’s actual package contents. A tube-only offer is not a controller-equipped heater.
- Read both element and controller nameplates for complete electrical details and obtain instructions for the exact combination; the published 16.5-inch length is not an installation-clearance allowance.
- If using the model-search action, verify TH-800S / 800 W, seller, condition and controller inclusion in the actual result; a model search does not establish an exact listing.
