## heating from 0 degrees to 70

Greetings to all. New member. I hope i am not stepping on an old thread but my search of the forum didn't show anything...
There are many calculators on line that estimate btu/hr required to maintain an indoor temperature. What I am looking to calculate is how long and how many btu's it would take to raise the indoor temperature to 70 degrees from a 0 degree start. This question pertains to heating a mountain cabin that we plan to visit during the winter but that is otherwise closed up and not heated at all. Is there a formula to determine how many btu's it takes to heat a given area by 1 degree? Knowing this would allow me to figure how long it will take to heat the place when we arrive and help me to determine whether or not to supplement an existing propane heater with an additional kerosene space heater to get the temperature up quickly. Ultimately I want to install a wood stove, but I believe this would be used more to maintain heat than it would be to heat the cabin from scratch.
Thanks to all. I would appreciate any advice.

Hello bobrok,

Hope your chosen user name isn't short for "Brother's Broke", but could be if your using propane, it's hit a high price here in Mid-Tenn.
Anyhow, the best way I figure out your answer is running a load calculation, that is how much heat is required at 0 degrees outside and 70 inside, then you could divide that number to get the amount of btuH's needed for the heat rise, but it's usually a curve on a graph, that is it takes more heat energy at 0 to get started, then of course less as you get warmer.

But really, a load calculation can give you just what you need, btuh's to be 70 inside with 0 outside.

and see if it will work for you, if not, do a search for "free load calculations"

You can turn the heat on from anywhere in the world. http://www.proliphix.com/NT-Basic.aspx __________________ I tear things down and build them up.

I have seen a set up where a guy has a solar powered webcam running thru ham radio equipment to monitor his cabin inside and out. It's nice but not really the direction in which I want to go.
