Thinking of energy savings: if 2 loads (or 4) when energy was as its least expensive, what a great use of time and talent. Rather then dragging it it out over several hours/ into the next day. This would probably call for an electric upgrade.
Like the cabinet above over the washers. Do not like it when the washers stick out. They also left alot of room which is nice in case you need to get different sized washers.
