An American innovation comes to the UK. Here is one of many borehole projects in the US using the revolutionary Rygan technology:

Mark Nussbaum, P.E. of Architectural Consulting Engineers from Oak Park, IL designed the Unity Temple geo system which represents the fifth national historic landmark venue supported by Rygan’s HPGX system. Unity Temple is one of nearly 100 system installations in the greater Chicago area.

Like all Nussbaum designs, a premium is placed on entering water temperatures with minimal pressure drop. “The performance results we achieved with Rygan-based systems are simply not possible with common polyethylene-based systems” says Nussbaum. “Due to the limited land space of Unity Temple, geo-thermal would not have been possible without this technology.”
