Copper does kill ich and so do pennies. But the problem with pennies is that they contain other heavy metals so they're no longer a suitable method for treatments.
I have to add that if you have other invertebrates including snails and shrimps, copper will kill them thus fouling your water quality.
I don't think raising temp will help coldwater fish.
We're just killing the fish who are intolerant of high temp.
The only way is continuous treatment of meds rather than increasing the temp.
On the side note, when trying to use a different med, remove the med you currently have in your tank using a carbon. Mixing meds can be dangerous.
