Lots of interesting opinions!

If you wanted a 2400w heater, 240v would definitely be the way to go. For a
750w it makes no difference at all. In fact, it doesn't even have to be a
dedicated line as long as you don't put anything big on it. Geez, it is
only 6a.

I "think" hydronic is supposed to be safer because the heat is more spread
out and nothing gets very hot.
