----- Original Message ----- From: "Jeff Barfett" > Arild, The Airhead does take air from the inside and pushes it out via a low volume fan which would allow room temperature air to move over the composting compartment.
REPLY It just occurred to me that the vent for such a composting toilet will require a bit of additonal engineering. The interior air will have moisture in it and this will form ice as soon as it exits outdoors. Therefore the exhaust air has to have sufficient velocity to blow past the vent grille or exit port before it has a chance to freeze and form an ice barrier. We have the same problem with our bathroom. Once the snow on the roof gets to be deeper than 24" it tends to create an ice block and our drains no longer work. I have been mulling over how to solve this. A longer pie isn't going to work because the ice will simply form inside the pipe instead of just blocking the exit opening. I need to install an air injection fan to blow th moist warm air out faster than hoar frost can form and perhaps also blow out any snow accumulations.
