Yeah, I was thinking about that this morning. My house dragons are methane sucking, forced air huffing beasts, but I need them when an arctic high locks us into the -40C zone for a month.
I don't enjoy the first startup. There's a puff of house dust out of the vents and a burnt smell from dust on the
dragon heat exchangers. I'll do it in the afternoon when it's warm
enough to vent out the dragon breath with big fans and restore air quality.
