then it may be a little more then the 800-1200 I said in the above post. Tho I am still not even close to convinced a sub is the way to go. If the hw heater is so close to the panel you cant install a bigger panel then thats a whole new issue, move it because its too close. can you move the panel left? right? turn it too face the direction? up? down?which would likely need to be moved since there's not space in the corner were it is currently (it's boxed in by the water heater and the kitchen door). Maybe I'm wrong, but that was my original thought process.
