ventilation for a calf barn
We are building a new calf barn and heard about some who have used inground geothermal heat that is drawn into the building by fans--supposedly maintains temperature in the calf barn at about 45 degrees year around. Has anyone done this? How deep do the lines have to be buried, what size pvc piping, how long, and how many? We are looking at roughly a 40x96 barn size.
