If we somehow could apply a significant amount of heat to the black hole, what would happen? Photons get redshifted near the event horizon, so how energy transfer towards black hole goes?

How do you propose to heat the black hole? Radiation? Sure, we could try shining a bunch of photons in it. This would increase the mass of the black hole, which, curiously, decreases its [effective] temperature!

Well, I didn't say to raise its temperature, I said to transfer energy by the means of applying heat to it.

So can we state that black holes are only known way to convert energy to rest mass?

That's not true. It routinely happens in particle accelerators and our own atmosphere.
