RV Electric Space Heater
Genel,
I would give some serious thought to what Gary has said about using electrical heaters.
In addition to his points, remember this, the heating ducts are normally routed through the same areas that the water pipes are routed and in many of the RVs the heat ducts are also routed so that they will supply heat to the basement areas of the RV. This way the holding tanks are heated also.
If you spend any amount of time reading the seven or eight RV forums that are on the internet, you will see that in almost all cases the subject of "winter camping, freezing pipes, etc.. are found out to be from those people who use electrical space heaters to heat their RVs instead of the furnace system.
As for electricity being cheaper .... hhmmnnnn,, I'll have to see that to believe it.. Penny for penny, propane heat produces over three times the amount of heat that electricity does and at about one fifth the cost.
Example... here in northern Nevada where I live, my propane bill runs about $70/80 per month for both heating and cooking. If I were using electrical space heaters to heat with, my monthly electrical bill would be well over $200.00 per month and I still would have to have propane to cook with..
This is based on my previous RV that the furnace went out on me during the night and I had to spend over six weeks using electric space heaters to keep from freezing and were it not for the heat tape on the water hose and the skirting on the RV, I would have had frozen water lines.
A space heater is ok for use in the bathroom while taking a bath, but to try and heat the whole RV ??.... I'd give it some more thought.
This is just my opinion of course and everybody has their own..
Best of luck in whatever you decide to do,
John
