Humboldt Penguin Exhibit – Seattle, WA
Humboldt Penguin
Humboldt penguins like their water between 50-60 degrees F. Considering Seattle’s climate, that means the water needs to be cooler in the summer and warmer in the winter. But geothermal makes that easier. “The ground water alone is 52 degrees,” Maloney explains. The geothermal design for the pools operates on 2 stages with 2 compressors, one at a time, with a large tankless gas water heater as a third stage. Thanks to the temperate ground water, however, Maloney doesn’t think the system will ever need the third stage. The water-to-water heat pump also will cool the pool water on a reverse cycle in the event the water temperature rises above the desired temperature. This also operates in 2 stages.
