Submersible Heater

My heater says it is waterproof, but it has a minimum Water Level?

"I can not put everything in hot water? or only the minimum level of water? thank you for all the answers, but why does he fully submersible.?! full! ugh i dont get ITT.

Dice fully submersible, because it is! Do you know what "minimum" mean? – Is this the opposite of the maxim. You must cover the heater at least this level but can cover any level higher than an immersion.

Baby, It's Cold Outside Ok, I can take a joke about global warming and bird-watcher has but recently Temperatures were just ridiculous! In fact, scientists who study global warming that we should not confuse the phenomena climate change short-term weather extremes. But I repeat – This is ridiculous!
