By the way, I know this might be different around the country, but my system has 3000' of 1 1/2" pond loop. The rule of thumb for our climate is 500' per ton.
We have the same rule in Iowa. Out system has 2500 ft of tubing in the pond and about 800 ft in the ground. We had only puddle of water in the pond our first winter in the house. Top third of the coils was sticking above the ice but the house was still warm. Inlet temperature to the HP was around 26F for about a week during a cold spell. The coils were apparently covered in ice to the bottom.
