Model:
Boosts thermal efficiency to 98% at full fire!
The Raypak Condensing Heat Exchanger (CHX)
utilizes exhaust heat, which is normally wasted,
and converts it to useful energy that increases
overall operating efficiency. By isolating corrosive
condensation in the CHX, away from the primary
combustion chamber, the life of the boiler/heater
is extended.
Applications
• Domestic Hot Water
• Pool Heating
• Hydronic Heating
Available Configurations
• Top-mounted CHX
• Rear-mounted CHX
• Stacked boilers/CHXs

For Hydronic applications, minimum flow rates are
at 40˚F ∆T, except on model 402 which is 20 GPM.
For Pool applications, use 20˚F ∆T or Maximum
Flow column, as appropriate.
For series piping, add the pressure drop of the
boiler, CHX and piping to size the pump.
For dual-pumped Domestic Hot Water, size the
heater pump for the pressure drop of the selected
heater plus the pressure drop of the piping. Size the
CHX pump for 40 GPM @ 0.7 ft. of head for models
402 to 902 and for 60 gpm @ 2.2 ft of head for
models 992 to 2002 plus the piping.
