Orientation, Lakes & Ponds

Orientation of connections

It is immaterial which direction the fluid is pumped around the ground arrays - the connections to the heat pump are generic. It is essential that the slinkies

®

are

connected so that one end of each slinky

®

is connected to the "feed" manifold, and the other end is connected to the "return" manifold"; the effective length of

each of the slinkies

®

must be the same.

Using ground arrays in lakes, ponds, rivers etc

Since plastic pipe is buoyant even when filled, the arrays and their headers must be kept in place using weights. The arrays should be assembled on a stainless

steel mesh and held down using plastic zip ties. The arrays should be filled with air, not water, and floated into place with any weights attached. When in the

proper location, the arrays can be filled with water using a hose (providing that there is sufficient main water pressure) and sunk into position. Additional weights

may then also need to be carefully placed on the arrays. 

After commissioning

The “disturbed” ground surrounding the newly installed slinky

®

will not make perfect contact with the pipe initially. After several years of constant rain, and the

compression effect of the ground, conduction with the soil will improve. Essentially, if the building is heated successfully over the first winter, performance in later

winters will generally improve.

What will the water temperature coming from the ground into the heat pump ?

This will be anywhere between 2 and 5°C below “static” ground temperature—in simple terms, between 3 and 7°C
