Vented propane heater??
« on: Nov 08, 2010, 03:11 PM »
Does anyone know of a small vented propane heater? Kinda sick of the condensation with the big buddy heater, but cant find a small vented heater, all the ones I see are way too much for a small bob house.
thanks

A non vented, Blue flame heater burns 99.9% efficient and has no condensation. And (just a tip) with burning any type of fuel you should have a detector.

That is simply not true at all.  The chemical reaction for the oxidation of methane (natural gas) is as follows:

CH4 + 202 -> CO2 + 2H2O

That means that there is twice as much water vapor being produced than carbon dioxide.  It really is as simple as that.  Once the air in the shack/shanty touches a cold surface, the air temperature will be reduced to the saturation point and condensation will occur.  Insulation prevents the air from touching cold surfaces and condensing.

Condensation is usually a problem with insulation. It will be humid inside the shack but once that air touches a cold surface, it will condense. I have an insulated shack and don't get dripping issues. But with the flip over and a bigger heat you will see it more.  I'm not sure what a bob house is, but whats your insulation like?

A bob house, in this instance, is a small house for a guy named Bob.

I haven't had any problems with condensation in my shack at all when burning my blueflame heater (Propane). But when I used my Big Buddy heater there was condensation on my windows. I have a total of 5 windows in my shack. If your fourmula is true where is it going?

I found an old propane space heater at a garage sale for $5.00. The seller told me it was natural gas but I brought it home thinking about converting it and then realized it was made for propane. It was built by the Watt company and I have since seen similar versions made by the same company.  I use it in a 12x6x6 Clam pop up and I love it.  The inside of the ice shack stays dry and frost free.  And, my eyes don't get irritated like they do from non-vented heaters, both Mr. Heater Buddies.  I think you'll enjoy using a vented heater.
