In the fall of 2018, Mysa founders Josh and Zachary Green—who were also attendees of the Salvation Army St. John’s Temple—donated 15 first-generation Mysa baseboard thermostats to the church, free of charge. This provided an excellent testing ground, given the variety of applications within the building.
Thirteen Mysa thermostats replaced 43-year-old bi-metalic thermostat units in various rooms, but the most significant upgrade was the replacement of two 120V thermostats that controlled heating in large spaces: the sanctuary (39,700 watts for 5,360 square feet) and the gymnasium (35,250 watts for 3,358 square feet). By introducing a new neutral wire, the Mysa thermostats were able to manage all heating for these areas, though energy consumption had to be estimated based on relay usage.
Comparing data from the past three winters to the last winter before Mysa’s installation, the church saw an annualized energy savings of approximately 12%, translating to a cost reduction of about $3,300.
In September 2024, four mini-split heat pumps were installed in the sanctuary, and Mysa provided four Mysa AC thermostats to control these units. The savings have already been significant—approximately 30%, or $7,000 annually. While the majority of these savings are due to the mini-split installation, Mysa AC has played a key role by enabling remote control and scheduling, features that the mini-splits themselves lacked."
