Groups Collaborating to Amend Illinois Technical Reference Manual
September 22, 2014
The group’s amendment would allow GHPs to be compared to 80 percent efficient natural gas furnaces; include the desuperheater water heating efficiencies of GHPs; recognize the true cost of air-source heat pumps; raise the average by 54 percent; and extend the useful life of a GHP from 18 to 25 years.
Doug Dougherty said that even though getting GHPs included in the federal definition of renewable energy is one of GEO’s major issues, its efforts at the state level will not be deterred by a lack of recognition at the federal level.
The day-long event included a variety of comprehensive, hands-on opportunities for participants to learn about and observe all aspects of a geothermal system — from equipment specification, to loop-field drilling and trenching, to system controls programming.
The North American geothermal market claimed $102.8 million in revenue in 2012, and is expected to reach $147.6 million by 2017, according to Frost & Sullivan, a San Antonio-based market research and analysis firm.
