Wave 6...I'm concerned it may be too big for my Hawk. ...can the 6 be dialed down low enough to keep the camper comfortable?
Is your concern that the Wave 6 is "too big" in physical dimensions or in heat output?
I have a Wave 6 in my FWC Hawk, and it
is big. In my opinion, the potential downside of the 6 is it's
physical size, not that it puts out too much heat...at least, not the way I use it.
But how much heat is too much depends on how
you use the heater.
If it's 50°F outside and you want to raise the temperature to 70° inside a small camper then yes, the Wave 6 may put out too much heat even on low. If it's 20° and you want to raise the temperature to 70° then the Wave 3 may not put out enough even on high. (I'm just making up these scenarios, but you get the idea...)
I usually don't turn on my Wave 6 until/unless the outside temperature gets down towards 40°.
Of course, one solution to "too hot" is to just vent the camper a bit more, let in more outside air.
Remember that since you have to vent the camper (to bring oxygen in and let combustion products out) with a catalytic heater, when it's really cold outside you're venting in "really cold" air, so the heater will have to work against more than just heat loss through the camper walls/roof.
The physical size of the Wave 6 might be more of a problem if more than one person is moving around in the camper. I usually camp alone so I can tolerate the space taken up by the big heater.
The
Amazon.com page(s) for the Wave heaters lists physical specs and BTU output of all 3 sizes. Scroll down to the section called "Product Description", then the sub-section labeled "Olympian Wave-'n' Specifications".
