Ran my Hearth for over 4 hours on a APC 1400. Had over 70% capacity left (if you believe the LEDs)

You have a link to one of these APC smart ups 1500?

What are you using for an external battery? Thanks.

It ran that long with the internal batteries. I have 2 size 24 RV batts that I can connect if need be, but I don't expect we'll ever lose power for that long.

Did you run convection blower also?

Just as a data point, my Keystoker DV runs 79 watts with just DV and combustion blower. Adding the stoker motor give me around 93 watts total, and with the convection fan running, the grand total is around 180 watts. I was rather pleased to see how efficient the DV blower was, it really doesn't use much power at all.

I did not during this last outage. The weather was warmer so it wasn't an issue.
