Description

JBJ TrueTemp Titanium Heater TG2-800 — Professional-Grade Digital Heating for 160–260 Gallon Aquariums

The JBJ TrueTemp Titanium Heater TG2-800 is the most powerful model in the JBJ TrueTemp line — a professional-grade 800-watt digital aquarium heater engineered for precise, reliable temperature control in freshwater and saltwater aquariums from 160 to 260 gallons. At this scale, heater reliability, accuracy, and material quality are not negotiable — the JBJ TrueTemp Titanium Heater TG2-800 delivers on all three. The virtually indestructible corrosion-resistant titanium heating element provides superior heat transfer across the full water volume of a large display aquarium without shattering risk or corrosion vulnerability in marine environments. The precision digital touch pad controller delivers ±0.5°F accuracy with a large LED display showing current temperature at all times, and the remote probe placed up to 5 feet from the heating element provides true ambient temperature readings across the full depth and breadth of a large aquarium system. ETL approved for freshwater and saltwater use.

Key Features of the JBJ TrueTemp Titanium Heater TG2-800

The TG2-800 — Built for Large Display Aquariums and High-Volume Marine Systems

At 800 watts covering 160–260 gallon systems, the JBJ TrueTemp Titanium Heater TG2-800 is the heater of choice for large display reef aquariums, high-volume fish-only saltwater systems, and large freshwater displays where a single reliable heating unit is preferred over multiple smaller heaters. The titanium element’s corrosion resistance makes it the permanent installation choice for any large saltwater system — it will not corrode, will not shatter, and will not require the accelerated replacement schedule that glass and quartz elements demand in marine environments. The smart memory chip ensures that a power interruption in a large aquarium system does not require manual temperature reprogramming — a critical feature when livestock value in a 200+ gallon reef system can be substantial.

Remote Probe — Indispensable in Large Systems

In aquariums of 160 gallons and above, the temperature differential between the warmest and coolest zones of the water column can be significant without proper circulation. The JBJ TrueTemp Titanium Heater TG2-800’s remote probe placed up to 5 feet from the heating element measures true ambient tank temperature — preventing both false on-cycles that waste energy and false off-cycles that allow temperature to drop before the heater responds.
