Which are some natural circulation boilers? - Quora

The burner can be used to warm the water and induce a natural circulation. Of course, a water boiler's system circulator could be used, but this would change the concentration of chemicals by diluting them. For proper boiler maintenance, routinely monitor the chemical concentrations while the unit is in lay-up.
