Well I bought myself a Coleman Propane Blackcat catalytic heater to use in my portable ice fishing shelter. It's a 4 person so I thought the Coleman Blackcat would "take the edge off" inside and keep the Ice Cube a little warm. I knew it wouldn't make it REAL hot inside, just nice to keep you from getting too cold. First off, I liked that it was small and compact to keep in my fishing box. It runs on the small Coleman propane bottles and lasts up to 7 hrs on 1 bottle. I used it on 2 fishing trips on 1 bottle for about 6 hrs in total. That was using it on high all the time as well.
The temperature outside for both times that I used it was around -5 C, which isn't to cold in January but it gets a lot colder in Manitoba in January than that. I'm glad it wasn't -25 C! So after setting up the portable ice shelter, me and my wife started to fish. After sitting inside for about 2 hours, we started to get chilled. So I got the Blackcat out and sparked it up. The max setting cranks out 3000 btu's so I left it on high all the time. After about 30 minutes it warmed up inside, but not warm enough to keep us warm and comfortable. With this heater you can move it around quite easily and we had to have it very close to us to feel the little heat that it was giving off. It warms your hands and feet in time but the shelter was still a little to cool inside for my comfort zone.
On colder days this heater won't stand up to keep a portable ice shelter warm, that's my opinion. I'm going to use this heater now for camping season. Hopefully it will keep a tent warm on a cool night out camping this year. Don't get me wrong, its a good little heater but didn't stand up when I used it ice fishing. I bought a bigger propane heater which I'll be trying out very soon and give a review on in the future. Also always remember to keep the area your in ventilated as you need fresh oxygen at all times. In my shelter I have a roof vent and kept the door unzipped a little to allow air inside at all times.
