The Wii in and of itself uses very little power even while fully operating. Having said that I will say this. Wiiconnect24 should not generate enough heat to damage your system if you play it every once in a while and get the fans operating. However if you just leave Wiiconnect24 on for weeks while going on vacation or simply not using your wii it cannot be any good for the system itself.
Moderation, leave it on if you're using it every once in a while but if you plan to leave it off for weeks just turn wiiconnect off.. takes about 10 seconds. I turn it off to reduce it's electrical use over time but I do miss my glowing blue light..
