Water Circulation System | Boiler | Steam

Natural circulation is caused by the density difference between saturated water and heated water partially filled with steam bubbles. In a natural circulation unit the water tubes are connected to a loop, Fig. 4.3. Heat is applied to one leg, called the raiser tube, where the water–steam mixture flows upward.


Apr 20, 2020 · Hydronic Heating System Basics: Boiler heats water and pump circulates it through elements/baseboards. Cooled water is returned to boiler. System is designed, and pump selected to deliver xxx btu/gallon/hour at design temperature, commonly 0F. Boiler max water temp is usually 180F because higher results in boiler scaling.
