I need help in design of a Ground Source Loop?

Question

3200 SqFt home has two distinct areas served by two separate heat/AC systems. i wish to convert over to a geothermal system using two separate ground loops. I can
lay in 1000 feet of loop for each one. Is that sufficient, and what size poly pipe would be optimum for this purpose;
1 In., 1 1/4 In., 1 1/2 in, or 2 Inch? How far apart should I space the two lines?

Answer 1

I don't know.
