well when it comes to 'conditioned' air in the room/house....and using A/C-Heat, then having this dryers blower tossing it out the window, seems counter productive at times....
I know it would be a bit of a challenge for some installs....but wondering why they haven't come out with a sealed combustion type of dryer like the water and air heaters?
pulling outside air in to heat, toss with the clothing, and returning hot moist air to the environment......
doesn't really have to be completely sealed, but some sort of intake and exhaust setup....
in past homes I was in, if the laundry was in a separate room or bathroom, you could close the door and open a window just to exchange air for that given space, without taking conditioned air from the general part of the home...
some manufactured home have a in-take vent near the dryer to exchange the air, especially if the home is well sealed...
you would be surprised the amount of air that is pumped out during one dryers cycle...
some vintage dryers use to have upwards of 30,000btu burners...hence High Speed drying.....most of todays are around 18,000 to 22,000btu's....probably better for fabric care, and to match the washers cycle times....
but for the most part, the best your going to get with a dryers efficiency is a high speed blower, and an AUTO cycle, not allowing the machine to run any more than it has to...most have gotten more efficient than past years, but its not a big improvement in a standard dryer...
