Man, I am sorry (and pissed!) to hear about this! It seems everyday, someone is losing a tank full of fish (and in one case, the entire tank itself!) to a faulty heater. That's crazy...it's not an elaborate device. You think these big companies could make a simple product like a heater (it's water cooled for Pete's sake) with all their resources.
I am sure they have some disclaimer that their warranty will cover only the heater itself. But, with all the issues we are seeing, if someone lost $700 of personal property because of a faulty product, they should sue the morons. I know I would (even if it cost me money in the end).
The economy crisies of 2008/2009 crippled US Manufacturers. Where I work, many of our very best suppliers now operate like "Bob and Larry's Used Auto Parts". Multi-billion dollar companies are building junk...if they even get around to building it.
Damn, didn't mean to rant. Just that I put up with this type of stuff at work all day, then when I hear about some hard working guy's hobby and passion getting destroyed over a $40 piece of crap (knowing you won't get one bit of sympathy or reimbursement of any kind from them)...it sets me off.
I think those of you who have had heaters that have failed should get together and petition the respective companies to step up and take some responsibility for their products.
(By the way, on their website, under the FAQ, it says to go to your specific product to see warranty details. I did that. There are no links for warranty. Figures)
Again, sorry...and very best of luck to you.
