PE pipes for the assembly of a ground collector
Horizontal ground collectors ore a cheaper alternative to verticalGeoterm probes. Polyethylene pipes (PE HD) that are 25mm or more in diameter are appropriate for its assembly.
The collector is mode of one or more 1OOm-long loops which ore buried horizontally into the ground at the depth of approximately 1.2 to 1.8m.The heat from the ground is transferred to the heat pump via the collector containing the media in a dosed loop.
PE Geotermprobe
Technically, the geoterm probe is a bore hole of various depths in which a dosed loop system is inserted, through which a medium flows and, due to its lower temperature, collects the heat from its surroundings (geothermal energy),is heated up and brings it to the heat pump. The probes are usually placed up to the depth of 140 meters.
Probes are assembled from pipes, made from the PE 100 type material. A probe is made of four pipes, welded at the ends in a double U pipe.When inserting the probe into the bore hole the spocers are installed at regular intervals, which ensure the pipes are evenly spread along the width of the borehole.There is also a middle pipe which is intended for the final filling of the hole with liquid concrete at the end after the probe has been inserted and has withstood a pressure test. Concrete filling improves the thermal conductivity and thus the effectiveness of the operation of the probe as a heat exchanger.
