So I live in the 6500 days area but nobody told me they were all coming in one night a few days ago.

Around 7000, no wonder I use so much coal or propane.

So wait a minute guys - Cape Cod 5614, I froze my bippy off there one winter. Does this include wind and hence wind chill? Cape Cod has a TON more wind than we do as does N NYS and coastal Maine. Does human wind chill factor = building wind chill.

With c rapp y windows, wind really kills me.

You have pointed out something I have been trying to slam into some peoples' heads for the last three years. Wind exposure makes a big difference in heat load, and the more air leaks in the structure...the more of a difference it makes. I keep detailed records of coal burned vs. outside temperature, and for three years my "record" day for coal burned has not been the day with the lowest temperature...it was a day with -15 or -20 windchill. Hence my efforts to seal up the house...

Human wind chill does not equal building wind chill. Humans are moist and have evaporation which cools the body. That is why wind chill is lower than actual temperature.

Yes, infiltration is directly affected by wind velocity and is the greatest component of the heating load.

Keep in mind that heating degree days has nothing to do with design temperatures or specific heat loss. A "degree day" is only 24 hours at 1 deg F. below 65. It can be used to quantify the total energy use based on heat loss.

Here is a sample on how to calculate oil consumption based on degree days and heat loss.

The same could be done using coal, substituting coal values for oil values.

Those sum to 5,468 annual degree days for the past calendar year. It's best to get an average over several years (to decades) to set a good baseline, but this is good data.

6805 where I am now, which isn't bad compared to some of you-all, but not great compared to where I'm from, at 5014.

If you are not warm enough, have more coal on hand, and here is a simple solution and requires no analysis: Crank it up, or get a bigger rig to crank up. The two holer will be damned chilly if the wind is blowing through it, too
ALWAYS have an extra supply on hand or real handy. If you live by the degree days and you are an oil dealer, you will be crying or smiling from day to day. IF you are a propane dealer, the KY stays warmer with fewer degree days, more, it's a thermal shock....... This AIN"T rocket science....even though a few of you think so.

Understand what 'Steam-up' mentions, that all things are not equal in making the formula appear as a linear projection. If it's colder than normal, you will use more btu's from whatever source. Wind chill may not be technically a true form of heat loss, but anyone who has been on a hilltop or a frozen lake with 30 mph winds will surely disagree. :idea: :shock: ) doesn't hurt much, but 10 degrees and 40MPH winds KILLS!!!! Anyone Iceboat? Try that one for a chilly, bumpy, ride!
