Which system is more efficient: Vertical loop, horizontal loop, lake loop, or open loop (well to well)?
A – All closed loop systems are very close to the same efficiency. Less pipe is required for lake loops and vertical loops than horizontal. The efficiency of well water systems is slightly less because of extra power that is required for well pump. The pumps we use in our closed systems are only circulating pumps, as system is closed and requires very little pumping power. Electrical draw is a couple hundred watts.
