Anual heating cost calculation

Harold

Is this the way to calculate the yearly heating cost?

Net load number from Wirsbo design software = N. Difference between indoor and outdoor design temps used for calculation of net load = TD

N/TD = BH (BTU per hour per degree)

BH*24 = BDD (BTU per degree day)

Degree Day = DD

BDD*DD = BY (BTU per Year)

Then just take fuel net efficiency and energy content and calculate cost.
