Wheaton College Haas Athletic Center goes Solar.
In August 2017, Wheaton College’s Haas Athletic Center leveraged an $89,600 dollar rebate from the Massachusetts Clean Energy Center’s Commercial-Scale Solar Hot Water Program to install solar hot water collector.. The system uses a 1,248 square foot array of SunEarth Flat Plate Collectors, installed by Renewable Energy Systems, to heat the athletic center’s indoor Olympic sized pool and  locker room with showers and restrooms that is used by the athletes. The system is expected to save the school $30,000 while reducing carbon and saving up to 3,912 therms per year. Finally, the system’s design allows either the pool or the hot water supply to be heated to different temperatures depending on weather conditions, which will greatly increase energy efficiency.
 
Energy Metering Results

4 Months later and  the system is working beautifully!

Therm production on the system for the past few months is as follows:

Sept: 255

Oct: 227

Nov: 135

Dec: 78

 

Drainback with 360 gallons of DHW storage. Pool is 75' x 40', heated to 82-85 degrees

Two Onicon Revenue Grade meters are used for btu production numbers. One on the DHW side and one on the pool. This data is then sent to the Thermal Grid web based platform via the Resol DL2 datalogger


Project Summary:
