I have had the two 100 watt light bulb heaters running for about 5 days now.
I put one of my "Oregon Scientific" remote thermometers in the trailer and have checked it from here in the warm house 2 or 3 times a day .
With the temps running between high temps of 25* to 35* days to lows of 19* - 33* at night, the heaters have continued to maintain a 3* to 5*
degree increase in the trailer.
I know that the 3* to 5* is not much but the gain is in humidity.
The out door humidity is always much higher than inside the trailer.
The readings as I post this are:
House 72.0*F 31% H w/heat pump and dehumidifier/electronic air cleaner running
Outside 28.6*F 88% H
Trailer 33.4*F 70% H
Fish pond 35.2*F 100% H - go figure that one..guess the fish like it that way
These are the just about the normal differences I have seen so far.
The Dry-Z-Air units, 2, have not collected any moisture in this period.
Well, actually, one has a moist spot in the bottom on one side that is closest to a window but that is expected. When I started the lite bulb heaters,
I also changed out the Dri-Z-Air's. Prior to the L.B.H. the Dri-Z-Airs would collect about 1/8" moisture per month.
" Yes, these are about the SMALL gains I expected. But they are inexpensive, NO cheap, to build and operate.
And as stated above the humidity drop is a big gain
This is not enough heat to get me to sleep out there, but then I am an elderly person ya know so maybe
back 40 or 50 years or so, who knows!
You are probably a younger and wilder crazy guy. Go fer it.
Yes, all plumbing is drained and anti-freeze in drain traps & so on. All cabinets open and all that good stuff.
I leave the cabinets open when parked here at home all year around.
I also use a single 100 watt light bulb in my pump house. the pump house measures 8'W X 12"L X 8' H.
This single bulb has kept my pump freeze free for over 20 years and i think i have changed it about every 2 years but not religiously.
I only turn it on when the temps are dropping below 35*F or when I leave home. I have been known to forget and leave it on and only
find out when I go to get the weed-eaters or the pressure washer out of the pump house--- oh well. Forrest Gump had a saying about that.
If there are any changes, I will post them but I expect the results to remain constant.
