Return Temperature Stabilizer
Heating systems cycle-off when a facility is unoccupied to conserve fuel and save money. During this time, the water in the system cools. Re-introducing this cold water causes uneven boiler expansion/contraction, stressing the material which can lead to failure.
Smith Boilers with Return Temperature Stabilization
Smith's flexible iron in combination with our Return Temperature Stabilizer equalize water temperatures to minimize stress and extend boiler life.
How it Works
Cold return water is distributed into all boiler sections concurrently
through a tube running through the upper port
Return water cascades past the heated water in the upper section
Heating the water to output temperatures is accelerated and tempered through each section
As heated water circulates through the main section, it offsets thermal shock
caused by the introduction of cold return water
