<\/a> Despite being the largest “cat” heater I could get, the unit fits nicely in a spot right in the center of the Airstream. \u00a0 \u00a0 It is hung on the wall, looking like a black monolith from 2001: A Space Odyssey<\/a> where it won’t interfere with traffic flow and uses a relatively “dead” space. \u00a0 For a catalytic heater in a long trailer, a center location is ideal because the heat it produces needs to be distributed by natural air flow through the trailer.<\/p>\nIt works like this: We will open a center window near the heater to let cool air from outside spill down to the floor. \u00a0 This air will be warmed by the heater and rise up. \u00a0 Slightly opened roof vents at front and rear will create a natural flow through the trailer and bring the warm air to all parts of the trailer. \u00a0 We know this works because it’s exactly the system we used to keep our former Argosy 24 warm.<\/p>\n
The heater we’ve chosen produces 9,000 btus, which is far less than the 30,000 btu furnace that came with the Airstream. \u00a0 But that’s no problem, because a catalytic produces heat silently and steadily as long as it is “lit”, whereas the furnace cycles on and off. \u00a0 We used a 6,000 btu model in our 24 foot trailer and it could always keep the trailer warmer than we needed. \u00a0 Since these heaters don’t have thermostats (but rather just a Low-Medium-High dial), you regulate the temperature by opening the roof vents a bit more or less.<\/p>\n
I’m a big fan of catalytics, having used them in two prior trailers with great results. \u00a0 The only real disadvantages of the catalytic are that they produce moisture and consume oxygen. \u00a0 For both problems you must<\/em> have a window and roof vent partially open. \u00a0 Nine square inches of opening is recommended for this particular model, which isn’t as much as it might seem. And as I mentioned, opening the window and vent is the way you distribute the heat anyway.<\/p>\n The one remaining potential issue is that the catalytic heat won’t reach the holding tanks. Most modern Airstreams come with ducts to direct furnace heat to the tanks, to prevent freezing in really cold weather. Using only the catalytic heater we run the theoretical risk of a frozen tank but in reality we’ve never camped in temperatures sufficient to freeze a tank. \u00a0 An overnight low of 25 degrees (with above-freezing temperatures during the day) has never managed to freeze our tanks, and if the overnights are colder than that, \u00a0 I know how to drive south.<\/p>\n There’s usually a payback due to Colin for the work he does on my trailer. \u00a0 He is brilliant with mechanical things, and hopeless with computers and software. \u00a0 I’m just the opposite, so when he fixes my trailer I try to pay back with something he needs. \u00a0 In this case he wanted his email system fixed (on three computers) so it would send email reliably without getting “bounce” messages due to other people’s spam filters, he needed ![\"lake-champlain-northern-lights.jpg\"](\"http:\/\/tour.airstreamlife.com\/wordpress\/wp-content\/uploads\/2008\/07\/lake-champlain-northern-lights.thumbnail.jpg\" "\\"lake-champlain-northern-lights.jpg\\"")
<\/a>Microsoft Office installed on one computer, an external wifi card installed on Susanne’s computer, and cable Internet installed in his house with a wifi router. \u00a0 None of those are normally difficult tasks if you know what you’re doing, but Microsoft and the local cable company did manage to make everything harder than it had to be. \u00a0 By the time we’d been to Best Buy, the cable company local office, the shop, and his home, and installed everything, it was 6 p.m.<\/p>\n

<\/a>At the end of it all I was glad to be rolling down the road again, headed to home base with leaks fixed and heater installed. \u00a0 Lake Champlain was glassy calm and hardly anyone was on the ferry. \u00a0 The Airstream just seemed to serenely float across the lake on the top of the ferry platform, enjoying its semi-private ride past cruise boats and jumping trout, while the sun slowly set over the Adirondacks. I’ve parked it in the usual spot and set up camp for the next two weeks.<\/p>\n","protected":false},"excerpt":{"rendered":"
