Each THD heater uses durable titanium paired with an internal industry-standard quartz sleeve for steady, consistent heat output.

These guards create a vital barrier that prevents fish, plants, and corals from making direct contact with the hot tube surface. This reduces accidental burns or injuries, especially for larger or curious species, while allowing full water flow around the heating element for even, stable temperature control.\u003c\/div\u003e\r\n\u003cdiv\u003e\r\n\t \u003c\/div\u003e\r\n\u003cdiv\u003e\r\n\t\u003cstrong\u003eHow the TH and THD Compare\u003c\/strong\u003e\n\u003c\/div\u003e\r\n\u003cdiv\u003e\r\n\tBoth series use premium titanium for unmatched corrosion resistance and performance. The THD matches industry standards with an internal quartz sleeve and compact tube. The TH Series steps up with a thicker diameter and longer heating tube, giving greater surface area for stable heat distribution and lower cycling stress — which means longer life and greater reliability. When choosing Finnex, you know the THD is built to outperform standard glass heaters, while the TH is the go-to for demanding aquarists who expect the best.\u003c\/div\u003e\r\n\u003cdiv\u003e\r\n\t \u003c\/div\u003e\r\n\u003cdiv\u003e\r\n\t\u003cstrong\u003eModel\u003cspan style=\"white-space: pre;\"\u003e \u003c\/span\u003eVoltage\u003cspan style=\"white-space: pre;\"\u003e \u003c\/span\u003eAmps\u003cspan style=\"white-space: pre;\"\u003e \u003c\/span\u003eDiameter\u003cspan style=\"white-space: pre;\"\u003e \u003c\/span\u003eLength\u003cspan style=\"white-space: pre;\"\u003e \u003c\/span\u003eVolume\u003c\/strong\u003e\n\u003c\/div\u003e\r\n\u003cdiv\u003e\r\n\tTHD-300S\u003cstrong\u003e*\u003cspan style=\"white-space: pre;\"\u003e \u003c\/span\u003e\u003c\/strong\u003e120V\u003cspan style=\"white-space: pre;\"\u003e \u003c\/span\u003e2.7A\u003cspan style=\"white-space: pre;\"\u003e \u003c\/span\u003e0.62\"\u003cspan style=\"white-space: pre;\"\u003e \u003c\/span\u003e11.02\"\u003cspan style=\"white-space: pre;\"\u003e \u003c\/span\u003e40–80 Gal\u003c\/div\u003e\r\n\u003cdiv\u003e\r\n\tTHD-500S\u003cspan style=\"white-space: pre;\"\u003e \u003c\/span\u003e120V     \u003cspan style=\"white-space: pre;\"\u003e \u003c\/span\u003e4.5A\u003cspan style=\"white-space: pre;\"\u003e \u003c\/span\u003e0.62\"\u003cspan style=\"white-space: pre;\"\u003e \u003c\/span\u003e11.02\"  \u003cspan style=\"white-space: pre;\"\u003e \u003c\/span\u003e70–125 Gal\u003c\/div\u003e\r\n\u003cdiv\u003e\r\n\tTHD-700S     120V     \u003cspan style=\"white-space: pre;\"\u003e \u003c\/span\u003e7.3A\u003cspan style=\"white-space: pre;\"\u003e \u003c\/span\u003e0.74\"\u003cspan style=\"white-space: pre;\"\u003e \u003c\/span\u003e12.99\"   \u003cspan style=\"white-space: pre;\"\u003e \u003c\/span\u003e110–200 Gal\u003c\/div\u003e\r\n\u003cdiv\u003e\r\n\tTH-300S\u003cstrong\u003e*\u003cspan style=\"white-space: pre;\"\u003e \u003c\/span\u003e\u003c\/strong\u003e120V\u003cspan style=\"white-space: pre;\"\u003e \u003c\/span\u003e2.7A\u003cspan style=\"white-space: pre;\"\u003e \u003c\/span\u003e0.75\"\u003cspan style=\"white-space: pre;\"\u003e \u003c\/span\u003e10\"\u003cspan style=\"white-space: pre;\"\u003e \u003c\/span\u003e40–80 Gal\u003c\/div\u003e\r\n\u003cdiv\u003e\r\n\tTH-500S\u003cspan style=\"white-space: pre;\"\u003e \u003c\/span\u003e      120V\u003cspan style=\"white-space: pre;\"\u003e \u003c\/span\u003e4.5A\u003cspan style=\"white-space: pre;\"\u003e \u003c\/span\u003e0.75\"         13.8\"      \u003cspan style=\"white-space: pre;\"\u003e \u003c\/span\u003e0–130 Gal\u003c\/div\u003e\r\n\u003cdiv\u003e\r\n\tTH-800S       120V\u003cspan style=\"white-space: pre;\"\u003e \u003c\/span\u003e9.0A\u003cspan style=\"white-space: pre;\"\u003e \u003c\/span\u003e0.75\"\u003cspan style=\"white-space: pre;\"\u003e \u003c\/span\u003e16.5\"      140–265 Gal\u003c\/div\u003e\r\n\u003cdiv\u003e\r\n\t \u003c\/div\u003e\r\n\u003cdiv\u003e\r\n\t* While the THD-300S titanium tube is longer than the TH-300S, the TH-300S — like the entire TH Series — features extended quartz glass sleeves and coils within for premium longevity and superior heat distribution, making it the premium choice.\u003c\/div\u003e\r\n\u003cdiv\u003e\r\n\t \u003c\/div\u003e\r\n\u003cdiv\u003e\r\n\t\u003cstrong\u003eTitanium Heating, Trusted Since 2001\u003c\/strong\u003e\n\u003c\/div\u003e\r\n\u003cdiv\u003e\r\n\tFinnex has specialized in advanced titanium aquarium heating solutions since 2001 — over two decades of engineering reliable, innovative heaters trusted by hobbyists, breeders, and professionals around the globe.
