question about underbelly heating
This is my first trailer with ducted, under floor heating. With the enclosed underbelly, I understand that some heat goes into the enclosed space to help keep the piping down there from freezing. Is warm air actually vented into that space or is the fact that the ducts are down there supply enough heat. I haven't had to use the furnace yet but noticed that if I turn one of the ceiling vent fans on without any windows or door open, a fair amount of air is pulled out of the floor vents.
