Geothermal
Ice Arenas

Ice rinks are unique buildings from an energy perspective. Even in the coldest part of the year, heat needs to
be extracted from the ice to maintain the skating surface.

In a conventional ice arena, heat is taken from the ice and rejected into the atmosphere. Then additional energy
(and money) is used to heat the rest of the building.

In a geothermal ice arena, instead of rejecting this "waste heat" from the ice surface, it can be used to heat the
rest of the building, warm spectator seats, provide snow melt on the outside sidewalks ot even heat the building
next door. If heat can't be used at that time, it can be stored in the earth loop buried in the ground outside.
When the heat is needed, it will be extracted from the earth loop and dispersed inside the building. Instead of
spending money to get rid of the heat you take out of the ice and then using more energy to heat the building, the
Geothermal System recycles the heat inside the building. It leaves more of your budget to promote your rink and
skating programs and it's a lot better for the environment.

Harty Mechanical, Inc. works with Earth Energy and Ice, LLC to educate arena operators and owners about the
benefits of installing an geothermal ice arena in their area. There are 6 geothermal ica arenas in Minnesota with
Harty Mechanical, Inc. installing 5 of the 6 systems. Please check out our Job Progress Page to see Geothermal
Ice Arenas in progress.
