Another concern with it getting that hot would be that it may have effected the temp sensor. I have had spotty luck with those Won Brother titanium heaters. I walked downstairs one day to see the readout saying 102 degrees. I freaked and stuck my hand in the tank to check it out and it was cold (like around 73 degrees). I've had other similar, but less extreme, things happen with them. Since they are prone to sensor failure, I would check it out before you depended on it to heavily.
