Anything over 6-7kw is a lot for even a house. I am not sure if your house will be able to handle 8600 watts in the circuits.
Confirmed, my 6kw heater needed special three-phase installation just for it self, with enhanced fuses on each phase. I suggest anyone ordered that amount of Avalons call's an electrician before plugging all that in the wall, otherwise some interesting side-effects may occur
