Geothermal: what’s new?

Energy Efficiency: Heating, Cooling, Ventilation

According to Larry Rasmussen, geothermal product specialist with Gustave A. Larson, there are two significant advances in geothermal technology consumers should be aware of. Both efforts offer greater energy efficiency for geothermal equipment.

1. As of January 1, 2012, ENERGY STAR® raised energy efficiency standards for geothermal equipment to “Tier 3.” This raised the requirements from the 2111 standard of an EER (Energy Efficiency Ratio) of 15.1 to 17.1, a 6% increase in efficiency. In effect, Larry says, this means that all equipment now available is 2-stage, rather than single-stage, “and the products being manufactured today are the most efficient ever.”

2. Variable-speed pumps for circulation are replacing standard circulating pumps for both geothermal loops and infloor geothermal units. By later this year, these should be moving into the marketplace. Be sure to ask about this option if you are considering a geothermal installation, as you may increase your efficiency by installing a new unit.
