A fascinating piece of early American engineering, this antique Minneapolis Heat Regulator combines a wall thermometer, mechanical thermostat, and clock into one elegant brass instrument.
Manufactured by the Minneapolis Heat Regulator Company in the early 20th century, these innovative devices allowed homeowners to automatically lower or raise the temperature of their coal-fired furnaces based on the time of day—making them among the earliest programmable thermostats ever produced.
The Minneapolis Heat Regulator Company later merged with Honeywell, making this an important piece in the history of modern home climate control.
