en.Wedoany.com Reported - The Arverne Group offers a 50-year warranty on shallow geothermal probes installed by its subsidiary DrillHeat, a first in the French market, highlighting the company's commitment to the durability and reliability of shallow geothermal installations.

Under the warranty terms, if a probe fails, coverage includes repair, replacement, or a refund. In the event of a leak, the DrillHeat team is responsible for repairing and restarting the system, while completing necessary tests. If repair is not possible, a new borehole will be drilled to replace the defective probe. When no other viable technical solution exists, the cost of the defective probe will be refunded.
"A well-designed, correctly installed, and properly maintained heat exchanger should be durable. By offering this 50-year warranty, Arverne provides DrillHeat's partners with visibility and security that did not previously exist in the market," said Patrice Landholt, CEO of DrillHeat. Founded in 2022, DrillHeat is a subsidiary of Arverne specializing in shallow geothermal drilling. The company recently achieved the installation of its 100th shallow geothermal system, corresponding to a cumulative drilling depth of 130,000 meters. With six drilling rigs, DrillHeat operates the largest fleet of surface geothermal drilling rigs in France.
