Hey guys...I'm looking for advice on the best way to power an insert fan during a power outage. I did buy one of those echo-fans that run on the heat generated from the stove or insert, but I'm told they don't really work that well, especially with an insert? I'm concerned that during a power outage with extremely cold temps...I won't be able to move the heat throughout my 2000sq ft. home? I've read some posts where people have said they use a marine battery or something like that and just plug the insert fan directly into it to power the fan?? Seems to me there must be some way to keep a little fan running by battery power rather than having to buy an expensive generator and have an electrician hook it all up? I can't imagine the insert fan uses that much power...anyone have any ideas on this?
