Laying buried pipes generally require a depth of 2 meters, and vertical buried pipes require 100 meters deep or more. As for the tiled area, you need to consult your installation engineer for advice, because the geology of each area is different, and the parameters are different. 2.Is there any difference between the vertical buried pipe and the laid buried pipe of the ground source side pipeline of the ground source heat pump? The temperature of the ground source side of the vertical buried pipe is more stable, and the unit efficiency is higher, but the buried pipe cost will be relatively high. The temperature of the ground source side of the laying buried pipe is easily affected, which leads to a decrease in the efficiency of the unit, and occupies a large area of open space, but the cost of the buried pipe is low.
