The twenty-first century marks a new era for the world’s oldest and most reliable heat transfer system—steam. The secret to high tech steam is the trap. The better we trap steam, the more energy efficient and powerful our systems become. Today, with closed-loop systems, electronic controls, and 100% calibrated traps, steam has re-emerged as one of the most cost effective and reliable energy transfer systems for institutional, commercial and multi-unit residential applications.

In a properly designed system, nearly all of the energy used to produce the steam can be delivered to a terminal component or heat transfer device and released. A modern steam system, even an upgrade of a hundred year old system, can actually be more efficient and reliable than any other type of heating system.
