Method: Roster of 10 independently re-verified submersible aquarium heaters spanning entry-level fixed-thermostat glass heaters (Tetra HT30), classic adjustable glass heaters (Eheim Jager 150W, Fluval M150), electronic plastic/glass units (Fluval E300, Aqueon Pro 100W, Cobalt Neo-Therm 100W, Orlushy 300W), and titanium models with external control (Finnex HMA-200S, hygger 500W Titanium), sourced from specialty aquarium retailers and review sites (AquaCave, Bulk Reef Supply, TheHiddenReef, KensFish, BucePlant, EheimSupport, ReptileSupply, ThatPetPlace, ReviewAqua, NationalWPSupply). Every kept product has at least one source that was successfully live-fetched on 2026-08-16. wattage_w is a unitless number; tank_size_range_gal is a string in US gallons; temperature_accuracy_f is a manufacturer-stated tolerance string in °F, left null where only an adjustment/selection increment (not a true accuracy tolerance) was published or where the only source was blocked; boolean specs record a feature only when a source explicitly addressed it, else null. Two candidates were dropped: ISTA Titanium 300W (no confirmed titanium submersible spec sheet — only the inline I-H615 / unverifiable I-H790), and hygger Submersible 300W (both its Amazon and hygger-online.com pages returned server errors / 403 on fetch, leaving no verifiable source for existence, price, or specs). accessedAt 2026-08-16.
