Which type of boilers does the STRA consider under Limited Heating Service?

The STRA, or the State of Michigan's boiler regulatory framework, distinguishes various boiler types based on their design and capacity for heating service. Under the category of Limited Heating Service, the specific boiler type outlined is gas-designed sectional boilers under 1 million BTU.

This classification is significant because gas-designed sectional boilers are known for their modular construction which allows them to efficiently heat spaces while maintaining lower emissions compared to larger, conventional boilers. The limitation to under 1 million BTU means these boilers are suitable for smaller heating applications, making them a common choice for residential or smaller commercial settings.

Furthermore, this categorization helps ensure safety and compliance with regulations, as smaller boilers typically have fewer safety hazards compared to larger units. Therefore, the focus on gas-designed boilers under the 1 million BTU threshold reflects both practical applications in heating services and regulatory measures to promote safety in design and operation.
