Since they are essentially emptier+pump buildings combine, it seems a bit OP to not have them require any power. They can probably be more efficient since they already contain the element, but they still should use at least some. Use half of what pumps need.
I personally think this should be simply the non-configurable default, but that would break existing saves. So for backwards compatibility, this is optional and disabled by default :-/. I don't see much point in being able to configure the exact power usage, and it'd also make it harder to know what to change it to in order to have this somewhat balanced (since the default then would be presumably 0). Feel free to tweak as you see fit.
