I've been tossing the idea of an opional heater around for a while as well...
Last winter we stayed in mid-central Florida for our maiden voyage and the temps droped overnight to 38 degreese... we had our trusty fan driven plug-in heater on stand-by but I wanted to make sure the LP heater worked... Boy, did it ever!!! But, at a cost...
After midnight and set at 68... It kicked on with a roar from the gas ignition and then the fan would rattle and hum until the heat exchanger cooled down... for 10 hours I let the house heater cycle automatically... And, I went through a 1/4 tank of gas...!!!
Next night... the plug-in... On, Off, On, Off, Drove me nuts! (I need quiet...)
I found these options this last summer and settled on the glass radient wall heater... for only $99.00 per unit...
It's a Qmark / Marley FDI1500 Electric Drop In Floor Heater - 120 VAC - 1500 Watts... But at $185.00 it is a bit pricy and it said nothing about "sones" (the noise it makes...)
Then I found...
It's a Aura DGFP15120B 1500 Watt Glass Radiant Heater with Digital Temperature Control... it's adjustable from 750 watts to 1500... It plugs in and is wall mountable... (can't put it on the ceiling because of the tip protection...)
But for $99.00 (plus shipping...) it's a great deal and QUIET!!!
I got two from
