I'm very paranoid about leaks. The design in which the glass heater is going through the cordgrip allows for easy adjustment of the temperature and the assembly is very easy.

But I personally would put the entire heater inside the housing and have only the electric cord come out of the whole contraption. Since there will be good water flow in this DIY chamber if the heater ever breaks close to the cordgrip the tank will empty in a matter of minutes.

Wouldn't using an unbreakable [well almost] heater like the Stealth negate this issue?
