I think you are going to need a generator for a heater. They consume a lot more power than an mp40.Can that only be used on EchoTech products or can you use it for anything? I have a batter air pump I put in the tank to get oxygen, but what I'm worried about is heat. I live in Maine, when power goes out it is usually because of a storm, which means its cold. When I turn my generator off at night the temp in the tank can drop 8 degrees. Everyone was fine, but I don't want to risk it. This storm was in April so temps were in the 30+ range, in January we are negative numbers.
