A 1500 watt heater only puts out 5,280 BTUs. Do the math....A 300 watt heater will produce 1,050 BTUs. about the same as a couple candles.....
I was just under the beast and it looks like I could box off along the frame rails nice and easy with the insulating boards. This will not help 100% with keeping heat in the rv but it will protect all the tanks, lines, mechanics, which is my main concern.
My plan was to heat the underside with 2 small 300watt ceramic heaters to prevent freeze ups.
What ever I do I will post pics and results after the first deep freeze. {I don't believe I just said "deep freeze", in Tenn.!!! {I'm from upstate NY originally}
The reason for the smaller heaters, is because of available 20 amp service outlet. I have over 60 feet of heat trace wire on the fresh water hose, 3 dump valves and sewer piping under the rv.
This will add heat to the underside also, while using about 16 amps of power.
By the way, I have used 2 small candles under chafing dishes to keep foods hot at parties.:)
