exactly, the part that surprises me is that if this technology takes our heat energy, won't the body balance be disturbed, how much homeostasis balances it will take and I think that it will experience unexpected results in the end.

It likely won't have much impact if any on overall body energy balance because the heat dispersed through our skin is residual. However I would imagine it only harnesses a certain amount of the little available.
