98%High-efficiency Hi Delta with optional CHX
condensing heating system
Hi Delta with CHX achieves unequaled 98% thermal efficiency at full fire. It combines
the reliability of the Hi Delta boiler with an optional CHX heat exchanger which pre-
vents condensation in the heater’s primary combustion chamber. Self contained sec-
ondary heat exchanger can be inspected and maintained without disturbing the vent
or plumbing connections. The result is an ultra high efficiency heater that lasts.

Stacking two Hi Delta 2342 boilers provides over 4.6MMBTU in just over
26 square feet plus clearances. All components (except pumps and PRV’s)

hanging off the unit. The units remain fully serviceable even while racked.
