A few days ago, I was fortunate to be given a prototype of a new submersible heater under development, which will eventually be released by one of the major aquarium equipment companies. It’s made of carbon fiber with a thermal shutoff, a patented out-of-water safety shut-off, and patented thermostat. I also passed along a couple of improvement suggestions, which I hope will be implemented.
Stay tuned for more information about this heater. At present, there is no set date for it to hit the market.
