this is an old thread, but hey what the heck i will add my 2 cents,
i bought one of those canadian tire backup gens. and it works, i just started my tank today and alrighty had a power outage in my house, i got 3 things running on it, pump for the sump, heater, and powerheads i thought i would see how long the little thing can run for and it was a good 4 hours....
just my 2 cents
