Question about power...

[spreerider]

find the wattage of all your devices and add them together, you should not exceed 1440Watts on a single 15A circuit, you can multiply your heater by .8 as it wont be on all the time unless your room is very cold.
Also all the plugs in a room are probably on the same circuit so plugging into one on the next wall wont change much,
If you are not tripping breakers or planning on adding any other devices you are probably fine with what you have.
I have a 25g salt tank and a 55g salt tank on the same circuit with my computer and tv and never had a trip, tho if all are on at the same time drawing max current for each device i would be overloaded, but rarley do i have all heaters lights pumps tv on full blast volume and computer on full volume running the highest end games.
