0ensnaturae 7 years ago ReplyUpvoteMeet a prize dummy. I want a submersible water heater too, and bought the Marshaltown 'Bucket Heater' at 34$ plus delivery charge - ie that put the price up to 54$. Had to pay 40$ import duty (europe) = 90$ THEN - discovered I had forgotten that 110v 1120v is no use here. Got to be 210-220v. So when I plugged it in, it got red hot and had to be switched off IMMEDIATELY - or it would destroy itself.SO - where to now? I can see how the bucket heater is made - with a sealed unit for the wiring. Otherwise it looks VERY simple - but could be very dangerous as a DIY project.However there must be a way to seal all the wiring inside heatproof/waterproof plastic. Elements (eg of the kind used for hot water tanks) come in all sizes and are easily obtainable. Only the waterproff connection is a puzzle at the moment , but cant be too hard.
