Case Study

Oak Hill Senior Living Center (2 Pipe System)

IL, United States



$4,148 (USD)



The performance of EndoTherm was piloted at Oak Hill nursing home in Monroe County, IL. Both heating and cooling feed the same hydronic loop (2-pipe system).

EndoTherm was installed, with no interruption or downtime to the heating system in operation, on the 18th
August 2020.

Historical consumption was provided with gas bills between November 2018 to July 2020. Both the
electrical (cooling) and natural gas (heating) was normalised using degree days from St. Louis Downtown
Airport (KCPS) at a baseload of 65°F.

EndoTherm was installed on the 18th August 2020. Thus the analysis covers 5 months between September
2020 and January 2021.
