| Abstract | Two large commercial greenhouses in metropolitan Salt Lake City have been placed on geothermal heat within the last three years. Economic results and comparisons with conventional gas heat show the advantages of geothermal in a very competitive market, where natural gas prices are only 60% of the national average. The 190°F resource proved very attractive, with a simple payback period less than a year. The much deeper, low temperature resource showed the need to squeeze the maximum heat from water, using economical equipment that would not be suitable for the higher temperatures. The impact of the current tax incentives are discussed. |
