Sorry for your loss, but your response was way rude.
Here is a solution so it won't happen again.
Buy 2 heaters, one for each side...they don't have to be a big as the original, but if one goes out the other will keep this horrible situation from ever happening again.
The heaters will not come on until the temp calls for it, so two heaters will not overheat the tank. One will however put out enough heat to keep the coral and fish alive.
Mine has a little red light that glows to tell me it is working.
