Description of Geothermal Methods

eci lineThe Open/Recycling system takes constant temperature water, typically 50F in New England, from the earth, reducing the return water temperature typically by 8F in winter and typically increasing by 10F in summer. As the source/sink water temperate remains unchanged throughout the year, this provides the highest efficiency of the three methods.

The Standing Column winter temperature is designed around a minimum of 45F , entering water temperature (EWT) in winter and 60F in summer (residential). Closed loops are designed around 32F, EWT in winter (with antifreeze solution) and 77F in summer. We only condone food-grad propylene-glycol as the antifreeze solution of choice.
