Anyone using the Mr. Heater "Journey" catalytic heaters?

There is some heat loss through that opening.

Any way, my point is that a small heater which runs constantly can put just as much heat into living areas as a much larger furnace that only runs occasionally.

Although, you are ignoring the fact that much of the efficiency of a unvented IS going right out the window and ceiling vent especially when you add in a little bit of wind above zero MPH.

Not arguing that 1500 BTUs setting can create some heat under mild conditions to be somewhat comfortable. But in reality not enough once outside temps drop and the winds blow along with the square footage you are trying to heat.. Small area like containg the heat to just your sleeping area and sure 1,500 BTU might keep you cozy under a few layers of blankets.. Heating a 30ft space, well that amounts to trying to stay warm with a single candle..

I have heated my 26ft TT with one single oil filled radiator heater in winter to do some work.. At 1,500W setting you get roughly 5,200 BTUs.. Worked just OK when winter temps were in the 45F or higher and no wind blowing. Once temps got below 30F and a nice 10 MPH wind and took that heater hrs to bring temps up to 45F-50F.

TT came with a 24K BTU gas furnace, I upgraded that to a 30K BTU furnace.. Now if I want to work in the TT even on the coldest days furnace has no issue getting trailer up to temp that I am comfortable in without the need for long underwear, two layers of coats, heavy hat and thick gloves. As a bonus, the upgraded furnace runs for much less time than the smaller one, means less battery use.

Just depends on your perspective of what is "comfortable" living quarters temps..
