on 2 powercords you can easily run 4 vac motors and 1hp pump. the problems with wanting heat is the amount of power needed with either heater elements or inline heaters, you need at least 3,000 watts so a separate power cord is needed
I use 2 cords,
1 runs the aquemount, pump & the diesal burner
the 2nd runs 2 x 3 stage vacs, although I have enough reserve power to add a further 3stage vac.
You'd be amazed how much you run of a single 15amp plug, its only the initial power spike as you turn on the machine that blows fuses, you just need to turn on everything seperately.
