The full-load and part-load ELTs for ground loop heat pumps (GLHPs) are appropriate for cold-climate residential applications but not optimal for most commercial systems, and moderateor warm-climate residential systems.

If the optimum loop temperatures are less than 86[degrees]F (30[degrees]C) in cooling and 50[degrees]F (10[degrees]C) in heating, interpolation using ratings at the GLHP conditions of 77[degrees]F (25[degrees]C) and 32[degrees]F (0[degrees]C) are possible.
