A� This method is used to protect boilers from
condensate forming due to low temperature return
water� Generally noticed in large converted gravity
systems or other large water volume systems� See
Figure #7�
B� These methods are used to protect systems using
radiant panels and material they are encased in
from high temperature supply water from boiler
and protect boiler from condensation� See Figures
#8 and #9�
C� This method is used to protect boilers from
condensate forming as well as protecting heating
system from high water temperature� See Figure
#9�
