FAQ
Frequently Asked Questions
A thermosiphon is a passive heat exchange system that circulates fluid without pumps, using natural convection from temperature variations.
They are frequently used in solar water heaters, some refrigeration units, and industrial heat exchangers for efficient, low-energy operation.
It works by heating fluid in one area, making it less dense so it rises, while cooler, denser fluid sinks, creating a continuous circulation loop.
Both terms refer to the same concept, but 'thermosiphon' is the more standard spelling in technical English, while 'thermosyphon' is an occasional variant.
A system for circulating fluid without a mechanical pump, using natural convection driven by temperature differences.
Thermosiphon is usually technical/formal in register.
Thermosiphon: in British English it is pronounced /ˌθɜːməʊˈsaɪfən/, and in American English it is pronounced /ˌθɜːrmoʊˈsaɪfən/. Tap the audio buttons above to hear it.
