electric heat calculations

[shelco]

Does any one know of a web site or other source to calculate what is required for electric baseboard heat per size of the room?
Obviously other factors as well.
I have a customer that wants to tear out the LP gas heater and put in baseboards.

Sure, this one.

Check out this thread. I use 1.25 Watts per cubic foot.

Why would they rip out LP for baseboard heat?

I was taught years ago 10 watts per square foot.

I have always heard the 10VA per sq. ft. also.
Of course a R-O-T based on cubic feet does make more sense.

10 VA per sq. ft. = 1.25 VA per cu. ft. in a room with an 8' ceiling. I agree with kiloamp that the cu. ft. calculation makes more sense, and I too was taught 10 VA per sq. ft.

It also depends on your insulation and how cold it will get.

Thanks for the in put.
I really don't know why they want to replace LP for electric. I suggested to simply change out the old gas furnacce with a new high efficiency, but she still wants electric.
Maybe because LP here is about $2.79 to 2.89 per gal. and electricity is $.04 per KWH.

"Holy Crap", what does the power company use as fuel to generate the electricity?

We're around $.085 and I thought that was on the reasonable side.

I was taught that one cord of wood split, stacked and dried per month.

just remember that if done properly firewood can warm you 2 or 3 times,
once when cutting and loading,
then when splitting and stacking
then again when burning it

Better stop now , it's getting warm .....

The problem, of course, is that I do the first two steps in the summer, when I don't need to be kept warm.
