The Precision Submersible Heater is a new model of aquarium water heating device that Marineland put back in its catalogue after a long absence in this category. Following some major quality control issues regarding its Stealth heaters and a subsequent recall, Marineland moved very carefully to release their next heater with the Precision Submersible Heater.
The old adage “the more things change the more they stay the same” is especially true when it comes to the Marineland Precision Heater, which for all intents and purposes, appears to be an old-school Visi-therm. If you were keeping aquariums in the mid 90s then the look of the Precision Submersible Heater will be inherently familiar on the surface but of course Marineland didn’t re-release the Visi-therm without plenty of modern touches.
Actually just kidding, the only real difference about the Precision heater is the internal electronic assembly which has been updated to be more accurate in its temperature readings, and it includes a resettable fuse which will reset itself if the thermal switch turns off. The new and improved Visi-Therm Precision Submersible Heater will come in the same 8 sizes from 50 to 400 watts and it still comes with a lifetime warranty. [Marineland]
