WebOct 25, 2024 · A diagrammatic drawing of a standard U-tube exchanger borehole configuration is shown in Figure1, with U-shape pipes installed in a borehole and grouting material between the pipes and the wall. The heat carrier fluid is circulated through the piping system to exchange heat between the ground and the building end-users. WebMay 13, 2016 · Then I saw a Twister borehole heat exchanger and had to try this out. It seemed like a natural progression from the dU-tubes without the work. An improved quad U-tube with a twist! The manufacturer, agreenability.com claims 30% less drilling but my own results show even better.
