I want to put an immersion heater in my tank, but its fully baffled, common sense is telling me they will melt even under water as immersions get seriously hot...
or do i have no common sense ?
Nathan ? yours is baffled is it not ?
I could put some sort of cage around it internally to stop the balls touching it i guess.
My tank is a 500ltr upright wydale tank from purefreedom. The only internal baffle is the central divide. My immersion is 27 inches long and so it clearly reaches this divide in the tank, but there is about 5 - 7 inch gap from this divide to the base of the tank. My immersion slides across in this section and there is probably a two inch gap from the element to the central divide.
As you know I run my heater till the water gets into the 60's and low 70's. Nothing has melted or comes close to melting and the tank is insulated as well.
Yes the element stays hot, but I never run my water low enough for the baffle balls (that I have added) to touch the element, as those plastic balls are only very thin. I would imagine that if I used perhaps a 300ltr tank then the balls could touch the elements and then there would be a strong chance of them sticking/melting to it and causing problems.
