Which of the following statements regarding a hydronic heating system is
accurate in its description?
, 1. the water circulation must take the water from the boiler and move it through
the individual terminals or heating units where the heat is emitted and then
return the water to the condensate tank.
2. the water circulator takes the water from the feed pump discharge and moves
it through the individual terminals or heating units where the heat is absorbed
and any remaining steam turns to liquid then it is returned to the boiler to be
reused again.
3. the water circulator must take the water from the boiler and move it through
the individual terminals or heating units where the heat is emitted and then
returns the water to the boiler to be reheated.
