Pianotuna, I'm surprised you didn't get picked to be on Big Bang Theory. Did you mess up your audition?
Hi, It is 3413 btu's per 1000 watts. The ratings on heaters are....variable. It is best to use a kill-a-watt meter to do real time measurements of the wattage. The delta T, for my Class C, with 9980 btu's of electric heaters, between outside and inside the RV appears to be 23.2C. For example the temperature out side is -8.2 C (17.24 f) and the temperature inside the RV is 15 C (59 f). This suggests about 430 Btu's per 1 degree C delta T, or about 126 watts of heating. Here is a calculator so that a cost comparison can be made: electric vs propane -------------------- JJ from Pacific Northwest

Here's another interesting link on furnaces propane vs electric. I figure the 40,000 btu f=urnace in my RV is probably 60% efficient.

I figure the 40,000 btu f=urnace in my RV is probably 60% efficient. http://www.ehow.com/about_6645117_propane-...eaters-rvs.html It says "... a propane RV heater is more economical than an electric RV heater. It costs more than two times as much to use electric RV heaters as it does to use propane." That is true only if propane is much cheaper than it is now and electricity is much more expensive than rates in much of the country. For a scientific analysis of the cost of heating with various fuels, use this spreadsheet provided by the US Department of Energy: Heating Fuel Comparison Calculator Plug in your own per-gallon cost of propane and KiloWatt-hour cost of electricity. -------------------- Dave Rudisill

Hi JJ,
I'm glad I tickle you pink! (it also happens to be my favorite color). I'm sending Seasons Greetings to all my net friends and hope they get their "hearts" desire for gifts. I already know what JJ wants most and have lite a candle to help that happen. -------------------- Regards,
Don |
