This home is located right on Cascade Lake. Space restrictions didn’t allow for a pit with horizontal slinky loops. Instead a driller was employed to drill six vertical bore holes. Loop piping was then installed and grouted back to the surface. We fused the loops together into a header system that would ensure even flow through all six loops and brought the headers into the home. More below
Inside we installed two circulators, isolation valves, and connected to the water source heat pumps. As with all closed loop systems, the piping was then purged of air, freeze protected, and pressurized.
