Background Cockayne Farmstead (pronounced “Cah-cane”), originally named Glen Dale Farm, is located in Glen Dale, West Virginia’s Northern Panhandle, just over an hour’s drive from downtown Pittsburgh. It was originally an internationally prominent American Merino sheep farm covering over 300 acres in the 1870’s. When the reclusive final heir, Samuel A. J. Cockayne, passed away in 2001, he left his home and contents to the town of Glen Dale - and along with The Marshall County Historical Society - cooperated to preserve the farmstead.

When preservation of the interior began, one of the first tasks was to tag and remove over 1500 items accumulated over three centuries such as art, glassware, furniture, and correspondence. When the interior work was completed and the items returned for display, their preservation - as well as that of the home - was of utmost importance and climate control with energy conservation was a primary factor.

150 Year Old Farmstead Updated With Geothermal TechnologyCase Study

Cockayne Farmstead, Glen Dale, West VirginiaGeothermal Heat Pump With Humidification

A 6 ton Bosch two-stage TA071 geothermal heat pump with high-pressure Bosch Flo-Link flow center (inset) serves the Farmstead. Humidifiers (at left of heat pump) help protect historical artifacts displayed in the building.

Installation SummaryFor the geothermal heat pump portion of the project, Rumer-Loudin, Inc. was chosen because of their 24 years of experience installing geothermal systems in residential and commercial properties. Due to the property’s proximity to the Ohio River, President Sid Loudin knew there would be challenges drilling the wells. During a commercial geothermal installation on the Ohio side of the river, ancient riverbed was encountered, consisting primarily of gravel until bedrock was struck.

The system went into operation in October 2013. The architect was Heritage Architectural Associates. The general contractor was Centennial Preservation Group. The control system was installed by Quantum Controls Group. Funding for the interior preservation, including climate control, came from a federal Transportation Enhancement grant and through a Cultural Facilities Capital Resources Grant awarded by the West Virginia Division of Culture and History, and the National Endowment for the Arts as well as private donations.

Benefits and ConclusionTom Tarowsky, Program Director summed it up by saying “We are very pleased with the installation, as well as with the work that Rumer-Loudin performed. I believe that our project is among the first to have selected an energy-efficient geothermal heat pump as a solution to the humidity and temperature control needs of a historic and cultural resource. Given the nature of the Cockayne House, a large (3200 square foot), old (ca. 1850), largely uninsulated wood framed structure, we are also very pleased with the performance of the Bosch heat pump and its ancillary systems and controls.”

Another challenge was how to configure the loop. Over the years, the farmstead had been reduced to the home plus 1/2 acre of ground. To accommodate the linear footage necessary for the 6 ton loop, four 320 foot vertical wells were drilled rather than fewer, more shallow wells. Dillan Well Drilling of Darlington, PA cased each well down to 93 feet at which point bedrock was reached.

A Bosch 6 ton 2-stage model TA071 with a high pressure Bosch Flo-Link flow center was selected. TA Series* is a two-stage unit available in vertical, horizontal, counterflow and split system configurations from 2 to 6 tons. Its energy efficiency makes this unit the best-in-class in operating cost savings.

*TA Series is now replaced by Bosch Greensource CDi Series SM Model.
