We have the truma ultrastore and like most, the blown air heating is pretty poor. The fan works well and circulates well, but so much heat is lost in the ducting... Would it work better if we reverse the fan? Essentially instead of sucking the hot air down the ducts, traveling 3-4 meters is a cold environment and out the vents -> suck in the vents and out over the heater. To me it seems this would producer warmer air.
Question is would this cause anything to break? Anyone already tried it?
