‘‘Cow Heat”?
According to the February issue of Agri-News, a University of Missouri agricultural engineer is suggesting that owners of rural homes consider utilizing excess heat from farm animals to reduce fuel costs and cut energy demand.
Since most farm animals produce about 200 to 300 BTU per hour of excess heat for every 100 pounds of body weight, it would only take 10 cows or 2,000 chickens to keep a well-insulated, average-sized Missouri home warm in the winter. The agricultural engineer’s idea is to install heat pumps in confinement livestock buildings to pick up the extra heat.
"If a heat pump were set up to operate in the exhausted air from the livestock building, it would be possible to wartp the fanner’s home with one-third to one-fourth of the present fuel.
