LA-MONT BOILER. It is a forced circulation- water tube boiler which was first introduced in 1925 by La. Mont. The feed water from hot well is supplied to a storage and separating drum (boiler) through the economizer. Most of the sensible heat is supplied to the feed water passing through the economizer.

When manufacturers & installers talk about water heaters, especially combi-boilers, a key phrase used is "flow rate". In most cases this is really referring to how much water can flow through the boiler & how fast it can come out of a tap or shower head once the boiler is working.
