non powered 8000 btu heater with through the wall exhaust

[pianotuna]

Just what a boondocker who wishes to heat with propane needs. It even has a thermostat. It is available at Amazon for a lower price--but the write up at Home Depot is better. I believe it is lower cost than the unvented (and hence UNSAFE) wave catalytic units.

Hi,

That would put efficiency below 60%. I think that is unlikely. One could always add a 12 volt fan to the mix and that would almost certainly extract more heat.

The nice parts are that it does have a thermostat and is vented.

I get around 65% efficiency for the 8000 BTU to equal the 5140 BTU of the 1500 watt electric. That may be a tad low, but I doubt it is over 70%. Even the most efficient non-condensing furnaces are about 80%

Now there's food for thought. :E

According to the manual the rating is INPUT rating. Then it says "The efficiency rating of the appliance is a product thermal efficiency rating determined under continuous operating
conditions and was determined independently of any installed system." but it doesn't give the efficiency rating. I would be surprised if it was as high as 80%. A lot of technology goes into achieving 80%+ efficiency.

Start the car, let it warm up, hit the defroster in full-out, and it would make a saucer size clear spot in the windshield. Could not haul groceries in the bed. Lettuce, celery would mush, canned foods and bottles would burst. The nearest serious shopping was a three hour trip each way.

Black ice, black mood. Having to park the vehicles in the yard or risk getting smacked by the Michigan snow plow.

My main worry now, is the ice cream and did I remember to get sun block.

Dress code. Red Black Blue Green or Yellow shorts (white shows Mango juice too much). Color coded tee or polo shorts. Socks? I bought some maybe a dozen years ago.

Propane? Yeah I bought a hundred pound cylinder's worth around April of 2013.

Last electric bill was 243 pesos for 2 months. $14.82
(Because of the fans) next one should be $150 pesos $9.15 for TWO months.

Tonight, fruit salad Mangoes, Pineapple, papaya, cantaloupe, watermelon, and llaca. Topped with fresh unsweetened Mexican cream and brightened with wild desert honey.

I've paid my dues. Arthritis does not hurt from too much heat. Let the Slope Dopes frolic in frigid bliss. Our ocean beach water temp was 78 degrees here, and Jesús told me Las Peñas water was 83F last Friday. Reminds me, I've got some lobsters and a huge yellowtail filet in the freezer.

Any "heater" I come across will be in print. An obsolete crime novel about the mob.

The noise of the furnace fan rarely wakes me up but it is usually a comforting thing knowing the furnace is doing it's job and I drift back off to sleep happy. When it does bother me is when we are trying to watch TV and have to turn it up and down as the furnace comes on and off.

This would let us warm up the trailer with the furnace and then let the little heater keep it that way quietly.

Why spend the extra hundreds of dollars for a vented heater to supplement the existing propane furnace? Instead, replace the existing propane furnace with an RV propane furnace that finally "gets it right".

This 2-stage propane furnace uses on average less battery power and less propane and runs quieter - depending upon how cold it is outside, how well insulated one's RV is, and what temperature one wants the living quarters to be at. IMHO, all RV's should come with these propane furnaces instead of the good old Atwood single speed and loud RV furnace: http://www.pplmotorhomes.com/parts/rv-furnaces/rv-furnaces-atwood-excalibur.htm

Hi,

The co production soars when the O2 levels drop, further the catalytic continues to run when O2 levels are dangerously low. In that sense a blue flame is somewhat better.

You are also missing the point. It is not just CO that is a problem. There are other combustion by products that are nasty, too.

Then there is the lack of a thermostat. So the Wave heaters that folks wish to inflict on themselves are....too cold, or too hot.

Further moisture build up is high when using any unvented heater.

Finally--why have all the heat escaping through an open window and open roof vent? That's nuts.

BTW my daughter is a CO survivor. I will NEVER use an unvented combustion heater.

True Catalytic heaters (like the Wave) do not produce very much CO.. why does this keep coming up?

The risk in using them is Oxygen deprivation.

The OP must be talking about Infrared radiant heaters, like the Mr Heater Buddy.
