i live in a house built in 1738....we put in a new heat system, but didn't get the upstairs added onto it yet..
my studio is up there & i plug the space heater in for an hour b4 i go up there. it warms up quite nicely..
i can't run the heater & the sewing machine, trips the breaker...
did i mention that the breaker box is in part of the cellar you CAN'T get to from inside the house... have to go out the barn and all the way around the house...
i only did that once!
