Florida Home Inspector Practice Test 2025 – Comprehensive Exam Prep

In a steam-heating system, the operating cut-off control is generally set between 2 to 3 psi. This range ensures efficient operation of the system while maintaining safety. Setting the cut-off control in this range allows the boiler to maintain adequate steam pressure for heating purposes without excessively building pressure, which could lead to safety risks and system inefficiencies.

The 2 to 3 psi setting strikes a balance where the system can still deliver effective heating throughout the building, as most radiators and steam distribution systems are designed to operate effectively within this pressure range. Higher settings may lead to wasted energy and the potential for over-pressurization of the system, while lower settings might not provide sufficient steam for heating needs.

Understanding this optimal range is crucial for home inspectors when evaluating the functionality of steam heating systems, as improper settings can indicate maintenance issues or the need for repairs.
