Barbs80, tasker doesn't use much battery in general. I've been using it for about a year now with several different profiles and i don't see a big change in battery usage versus when it's not on. I personally don't use any battery saving profiles, tried that in the beginning and that was more of a pain than anything else. Sometimes i feel that by switching WiFi, data, and other things on and off constantly may actually increase battery usage instead of saving it. That's just my observation. Also having to wait for the connection for a few seconds makes me go crazy but that is probably due to me being impatient info so i suggest not getting to complex in your battery saving tasks. Toggling WiFi on at home and off when not is simple enough to avoid frustration.
