Installation of Borehole heat exchangers Probe installation in wells drilled with mud technology •Before running-in the probe, the borehole condition has to be checked with an appropriate survey, like a single shot run •To reduce lifting forces during installation, the heat pipes should be filled up with water •The mud density has to be checked to calculate lifting forces and required installation weights •If necessary reduce mud density by adding unweighted polymer fluid or use a desilter to separate fine solids from the fluid. •An appropriate method to overcome lifting forces is to use steel installation pipes which are connected at the probe foot
Installation of Borehole heat exchangers Preliminary measurements before installation • Check the pipes carefully of any damages like rabbles, grooves etc. • To avoid the entry of any impurities in the pipe system, seal the pipes tightly before the are running down in the borehole • Always use a reel for the installation work
