Right now it’s just a giant mud hole you could drive a four-wheeler straight into, but Nick Petrow says it is the future of his 111-year old family business.

That future, Petrow says, is with the underground geothermal energy system being installed at Petrow’s Restaurant at 60th and Center Streets. It is an array of 15 tubular wells dug 300 feet underground and a large water holding tank known in the trade as a battery, along with a variety of gadgets and gizmos that connect the whole shebang to the restaurant itself.

The idea behind such systems is to capture and recycle heat and water generated from restaurant operations using the underground tank and wells, which benefit from the constant subterranean temperature of about 50 degrees. In the winter, the recycled water stored underground absorbs heat from earth that can be used for the restaurant’s water heating.

In the summer, heat is expelled from the building and transferred via the recycled water to the cooler earth. From there, the cooled water can be reused to power refrigerators and air conditioners.
