Guess I was thinking to turn DOWN the hose heat because the outside air was so much cooler than the air coursing through the hose. I took it off Auto a while back since it seemed i needed to take care of a few things manually. guess i'll try upping the temp to see what that does tonight.
I had a brain fart many years ago when I was faster and stronger, but not so schmartt. We had just had a home built for us, and we had a hot water/radiator system put in, an efficient modern one with zone controls. When winter came, and temps were in the 0 deg F range, we wanted the living space to be warmer and the bedrooms cooler, which is normal. So, I reduce the temp settings in the upstairs area, expecting the boiler to increase temperature where the radiant heat was, in the kitchen and den area. What I didn't understand at the time was that I was working against myself and the boiler. My mistake was assuming the radiating surface area serving the downstairs would simply radiate MORE HEAT, and that area would be nice 'n cozy. It did radiate more heat, but there wasn't enough radiating surface to keep the entire house comfortable. We felt chilly watching TV. I finally clued in, one chilly night, and realized I had to turn up the heat upstairs so that those radiators could help with maintaining the temperature inside the entire house, which was a
single enclosed system. Needless to say, our experience was greatly improved once I got enlightenment.
In your case, if temperatures drop and the hose lining gets cool, water vapour will also cool and condense. You must either raise the air temperature, which increases the air's capacity to hold moisture, raise the hose temperature, which prevents condensation on the inner wall, or reduce humidity. Just don't go turning off your heat radiators like I did back in 1983.
