That's an accurate description of the Alde underfloor combo system, which provides a very even but relatively slow responding heat flow. But the Truma Combi is different, and much faster responding, providing the full 14000 BTU/hr output within minutes (20000 BTU/hr for the more powerful Comfort Plus version).
And that's actual thermal output, whereas traditional RV furnaces list BTU rates using gas consumption value where 20k BTU/hr gas consumption provides about 14k usable output at 70% average cycle efficiency.
...that was my experience, too, observing the Truma
1st hand (on a very, very cold day!) in a
pop-up truck camper. The truma is extremely efficient (something like 96% efficient). It blows the doors of any of the dinosaur RV furnace technology out there today.
