I recently installed a Camco/RV Catalytic Safety Heater, Model Wave3 in my 14' TripleE Surfside
Just wanted to let you all know how well it seems to be working.
That model is 3000/1600 BTU and seems to be fine for the near zero (32F) Canadian fall
I love the quiet operation (no fan) and radiant type of heat.
I was a bit concerned about the Carbon Monoxide (CO) factor, so I decided to take a few measurements (while I am NOT sleeping in it).
My CO detector has a digital readout, but I am not really sure how accurate it is, but some kind of indication.
I understand that the CO alarm should sound at 400 ppm, which is when it starts to get dangerous.
There is a good 8" x 8" vent that lets air into the RV near the heater, which is important to ensure good oxygen
The trick is deciding how much to open up your window vents to let the air flow through.
First I tried worst case scenario: All window vents CLOSED (except the intake vent). A floor measurement yielded 100ppm after 1 hour on highest heat setting 3000BTU. Not great to sleep in but probably wouldn't kill me.
Then I tried it with the roof vent open 1" at the mouth. A floor measurement yielded 30ppm after 1 hour on the highest heat setting 3000BTU. Interestingly it showed ZERO at the height of my bed (16" above the floor).
Anyway I am feeling good and safe now, as long as I leave a 2nd vent open slightly, as per the instructions!
BTW, I was using a Coleman BlackCat 3000 before this, but never really liked / trusted it.
It's heat was nice, but even after 2 years of regular use still had a funny burning paint
smell, that would trigger my smoke detector when I used it on high power, and leave me with a bit of a headache. It seemed to be getting weaker with old age too.
