What it is

The Ideal 174401 is a heat exchanger sub assembly manufactured by Ideal for its commercial boiler range. It forms the primary heat transfer component, taking heat from the combustion gases and passing it into the system water before the flue gases are discharged. This sub assembly is built for the F200 and F400 series appliances and is supplied as a serviceable unit for replacement work.
