Been wondering about a battery back up for our Pellet stove after a recent 4 hour power outage. My stove says its max draw is 3 amps or 3600 watts. Would be nice to have at least 6 hours of backup. I'm also looking at a small 4 stroke 1500-1800 watt surge 1000-1200 watt steady draw generator. Which it looks like could be the less hassle and almost cheaper long term option. Not to mention much more useful then just for power outages.
