Thanks for the advice. We're taking a knee now to fuel the barrel heater, so it won't be a big deal with the Vogelzang. If we find that it should be installed on some sort of brick or block, we can always lift it and shorten the smoke pipe. As far as framing in the porches, they've been designed for that. However, it ain't currently on my radar. To tell you the truth, that blast of cold air when the door get opened feels and smells good. And remember we use the cabin all year, so a breeze coming through the screen door is required during a hot summer day. Actually, I've got another solar panel on order, and will install a second 12V battery to the system. That might be able to power a fan to circulate the stagnant air for more comfort. And again, we don't live there, just visit for a week or so. Can put up with a little discomfort for that amount of time. And, I'll take too hot or too cold over bugs any day!
