Heroic Edition Rewards problem
If you can find the banking NPC (http://wiki.guildwars2.com/wiki/Banker) you should be able to transfer the heroic chest since the bank is account wide.
This is only if the items are account-bound, if it is soul-bound (or you already deleted the character) I suggest you contact support to get that resolved.
The stuff in the heroic edition is also available in the gem store if you didn’t know so don’t feel too bad about this if support doesn’t help you.
