Cannon Boiler Works Economizers

cbwThe Cannon Feedwater Heater is unique economizer designed to recover your exhaust stack energy and save you thousands of dollars each year. Cannon Feedwater Heaters pay for themselves by reducing your fuel bills. Cici Boiler Rooms will provide you with an estimated payback period when you inquire about an economizer, and it is normally less than one year.


Cannon’s high-performance Feedwater Heater will extract heat from your boiler stack gases. This heat is then returned directly to the water feeding the boiler, considerably reducing your fuel costs. Our ASME feedwater heater core features extended surface finned tube elements.

Compact Construction

The Cannon Feedwater Heater is a compact and durable box-type unit constructed to rugged boiler standards. This is not a disposable unit like many other designs, and will last as long as your boiler.

Rigid Steel Construction

The rigid steel frame is built to support the tube core, removable panels, the inlet and outlet transition and a stack of reasonable height. The frame is designed so that the unit can be supported overhead, avoiding any undue structural loads on your boiler outlet.

Removable Panels

The Feedwater Heater has removable panels on each side and one end for easy inspection and cleaning, if necessary. All four sides of the unit are insulated with panel-type construction and feature a stainless steel interior for added corrosion resistance.
