Glad to hear it's working so well for you, Ming. I love mine, too- not just for the efficiency of heating but for the quiet
. Ordinary RV furnaces are equipped with fans, noisy enough in a bigger trailer/RV, but in my opinion unbearably so in spaces as small as ours.
Which reminds me:
I added a fan to my heater that's not only powered by electricity generated by the heat itself, but is also stone quiet. Heat/air circulation is greatly increased thereby, allowing the use of the lowest setting on the heater. When I bought mine they were only made for wood stoves, but they now produce a model specifically designed for gas fired heat sources. Ecofan
Sounds like you have so much surplus heat that even distribution isn't so much a concern for you, but I noticed an immediate side benefit: greatly reduced condensation. Even the windows
stay mostly clear of condensate so long as the fan is in use.
