EarthKind® in “Hot Water”

EarthKind® Energy completes a new solar hot water heating system for HealthAlliance’s Benedictine Hospital in Kingston, NY.

In an effort to reduce energy costs and greenhouse gas emissions, HealthAlliance commissioned EarthKind® Energy to design a solar hot water system at Benedictine Hospital in Kingston, NY.

Twenty-eight solar thermal collectors were installed on a roof to gather the renewable energy of the sun and use it to raise the temperature of the water, so that Benedictine doesn’t have to task their furnaces to heat the water as much.

These solar collectors transfer heat to storage tanks via a heat exchanger. The solar side of the heat exchanger contains glycol antifreeze solution while domestic hot water is on the other side. Pumps operate to transfer this energy when the collectors are warmer than the solar storage tanks, for instance on a sunny day.

 

Hospitals are among a communities largest consumers of water and energy and heating water accounts for a substantial portion of energy use. Solar water heating systems, which use the sun’s energy rather than fossil fuels to heat water, can efficiently serve up to 80% of hot water needs.
