I have been looking at possibly installing a Heatmaster G series boiler next year. I am a wood stove guy, due to the simplicity and the off grid operation. However, my needs have changed and I am in need of heating more than one building as well as domestic hot water. My question is, what happens when the power goes out, as far as the fire is concerned? I know these things have blowers and electronics to control the fire. I do have a manually hooked up gasoline generator that will run everything but I am not home during the weekdays. For example, there was a random power outage the other day early in the AM. Was offline for about 2.5 hours, I didn't bother firing up the generator because I knew is was an isolated outage and would be back soon. That got me thinking about a wood boiler and electricity as I was laying in bed..
