Antifreeze added to boilers
must be nontoxic, and
must be of type speci
fi
cally intended for use in closed
hydronic heating systems. Under no circumstances
should automotive antifreeze be used. Antifreeze used
in any boiler may reduce capacity by 10% or more and
increase fuel consumption. Tankless coil performance
will fall as concentration of antifreeze is increased. Refer
to boiler and piping water volumes tables.
