heater worries

[ultmt45slay]

I recently looked at a post that said a heater that this person was using blew up, I was wondering, If you have a heater that is made for a 60 gallon tank, and its in with another heater exactly the same on the other end of the tank, I want to know if it might possibly explode as well. I have a 108 gallon and the heater on one end turns on about every 5 - 10 minutes and the other one never turns on, hardly at all. I have marineland heaters, not stealth though because mine is glass, not black plastic.

Visi-Therm Deluxe 250W 13 1/2" Heater

The Visi-Therm heater is completely waterproof and submersible. Features a visually adjustable temperature regulator and an easy to adjust dial for maximum control and ease of use. A long-life power lamp indicates on and off cycles of the heater, so you can tell at a glance if the heater is working. The non-ceramic element supports make this heater unusually light which prevents suction cups from pulling loose. Designed for use in both freshwater and saltwater aquariums. Extremely accurate magnetic switch for precise temperature control.

There are 18 of those heaters running where I work. And I own several myself.
They have not been running long, about 4 years or so I believe (could be wrong about the date)
None of them have had any issues.
