Backup power units?

That makes sense. Have you ever ran your backup unit? How long did it run your powerhead? The APC site does have charts on times but you never know how accurate they are.

*hangs head in shame* lol i don't actually know, even though i know i should test it. there were a few overnight power outages for a few hours each and i know the unit ran beautifully for each. how long would it last until the battery actually ran out? on a single MJ 1200, probably a pretty lengthy amount of time. mind you, after a while, when temperature gets to be a consideration (winter) then you may have to add a heater into the equation if you got no hot water (a good fire and an old school kettle still works though!).

Now that I think about it you can always warm up the water but you cant have a powerhead in there. That sounds good then if it worked for at least a couple hours.
