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
