Belgian developer starts digging hole for geothermal heat pumps in Bruges – pv magazine International


Property developer Steenoven and an undisclosed development contractor have begun drilling a borehole for a brand new thermal power storage system within the historic metropolis of Bruges, Belgium.

Steenoven has began digging a borehole for thermal power storage, with a depth of 150 meters, within the historic metropolis of Bruges, Belgium. With the assistance of an undisclosed firm, it drilled 120 wells into the bottom to put in 36 kilometers of pipes that may feed geothermal power to warmth pumps for a district heating warmth system.

Particular person geothermal warmth pumps will present heating, cooling, and home sizzling water to the residents of the Boevrie residential mission, situated within the UNESCO-protected historic middle of Bruges. The event will span 11,700 sq. meters and can embody 102 flats, 25 single-family properties, eight stacked properties, and workplace house, in addition to basements and underground garages.

Geothermal warmth pumps are being thought-about as a substitute for photo voltaic panels to cut back residents’ electrical energy payments, as UNESCO guidelines strictly restrict the usage of rooftop photo voltaic.

“We’re doing every part we are able to to make sure that this residential mission matches completely throughout the UNESCO web site, with most consideration to sustainability,” stated Steven Langenaken, mission supervisor for Steenoven. “Because of the form of Boevrie – a big underground parking storage with compact buildings above – geothermal power is probably the most correct and most effective means to offer sustainable heating.”

Geothermal warmth pumps have a mean supply temperature of 10 C to 12 C, in accordance with Steenoven. Their heating output will be 40 C for underfloor heating and 60 C for home sizzling water.

“In the summertime, the pipe community of the underfloor heating ensures that the chilly water circulates and the flats and homes are cooled rapidly,” stated Steenoven.

Drilling a borehole thermal power storage area requires a “excessive funding,” Steenoven stated. It added that the payback interval of the mission has decreased to about 10 years for the reason that worth of electrical energy elevated as a result of Russia’s invasion of Ukraine.

Drilling started within the second half of February and is anticipated to final two months. The primary residents are anticipated to start out utilizing geothermal warmth pumps by the tip of 2026.
