Question: Will the Caframo 9206 help de-humidify an RV that has propane as its main heat source?
Document: This is a small space heater which I use in my calf warmer, but it also heats my milkhouse. Very good product, would recommend to anyone that need a lot of heat with little space for a heater.
I was expecting this heater to keep my RV warmer than it does. I have a cheaper heater that does a better job. It is a quality heater just does not do the job I need it to. I have a motorhome and just wanted something to keep living area warm enough it works fine in the bedroom.
This has been an awesome heater. It actually works so good I have bought three for our boat, camper, and toy hauler.They are great at circulating the air even when it's not putting out heat so it keeps the area warmer.The one for the camper we used in Alaska and kept really warm.
I've tried everything I can think of but zip. I have to say that Caframo products are really quite expensive, and they even use almost all metal on this heater, but though I finally got a new Ecofan which has worked perfectly since, this is an appalling quality record. To the dump with this thing!
I was sent this fan by Caframo in Canada as a &#34;freebie&#34; after the third failed attempt by them to fix my EcoFan (and sending it 3 times to Canada). I thought this was nice of them. After turning it on to be sure it worked, I stored it in the box and have never used it until yesterday when my house heater broke. I soon could tell that the settings knob wasn't on right and was two positions off from the pictured settings.
This manufacture makes heaters for West Marine &#8211; which I have 3 of.When I was in need of another (new travel trailer) I found getting them direct was cheaper than West Marines&#8217; price.They have as many features on a portable heater as your going to find.I like the fact they lay prone. No chance of kicking them over. I trust them to stay on unattended in my boat and beach cabin as well.
The item showed up used and broke out of the box, I needed it to keep my boat engine warm during the freeze so I fixed it and used it, I asked the company to send me a new one and I would send this back once I get the new one, I even offered to pay for a new one so no risk for the company. Not very accommodating.
A great and nice looking space heater. Solid and strong.i especially like the snowflake setting as I'm using this in our cabin.
