Sorry for your loss.

I actually replace all the titanium heaters in the store, The failure rate was about 30% from the ones I replaced.

I use Rena's or Marineland Stealths in the store now.

I like the Hydor Inline heaters for home.

How does a titanium heater fail? Or do you mean the controller fails? I have a Won brothers heater and yeah only got about a year on it before the controller went wonky, but I assumed the titanium tube was still workable so I cut it off, junked the controller and tossed the tube into my salvaged-bits drawer for a day I might try to pigtail it off a Ranco heater controller or other electronic (ie. Profilux or Reefkeeper or whatever) type controller...

It is funny as I am slowly (not fast enough in my opinion) changing all my store heaters to titanium. NEVER had a problem with titanium as I use Jalli and Aqua Heat(sunlight supply).

Before you all run out to get stealth heaters, have a look. The new "pro" series seems to have a problem where it explodes (not exagerating) I have seen threads where they are blowing out glass on 200 gallon tanks. Not little cracks, but shards of glass on the floor.....
