geothermal/heat transfer

In the City of Toronto’s first joint geothermal project, 6,200 feet of pipe were drilled under the public laneway beside the hostel.

The fluid-filled pipes tap into the constant 10° to 12°C temperature found deep in the earth, then wind their way back to the hostel where that heat is transferred to the building via heat pumps, providing carbon-free warmth to rooms and common spaces.

In summer the reverse happens. Heat from the building is transferred to the fluid in the pipes then pumped outside, keeping the temperature cool and comfortable.
