Antifreeze added to boilers
must be non-toxic, and must be of a type specifically 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 in this manual.
