Case Study

Station Medical Center

Altoona, PA, USA



$5,157 (USD)


89,760 lbs

A pilot of EndoTherm was run at the Station Medical Center in Altoona, Pennsylvania, USA.

Historical consumption was provided in the form of gas bills stretching back from January 2017 to November 2018. These bills were in two-monthly intervals.

A regression analysis was constructed using the gas bill data, normalized with Heating Degree Days from Altoona-Blair County Airport (65°F baseload).

The baseline’s line of best fit equation (y = 0.204x + 811.45) will be used to predict consumption based on the post-EndoTherm recorded HDD values. This is compared against the predicted consumption to determine the success of the pilot.

Total Cash Saving:

$5,157 (USD)

Total CO2e Saving:

89,760 lbs

The pilot saved 747.38MCF compared with the predicted baseline. At $6.9 per MCF this is a saving of $5,157 and a saving of 89,760 lbs of CO2e. Taking all savings in to account an ROI of within 12-months is expected.


“We are very pleased with the results of the EndoTherm energy savings program, it has worked better than our expectations. I would recommend use of this product in any leak-tight hydronic heating/cooling system.”
