The ReCon high efficiency water heater has been specifically developed as a KC1000 water heater replacement. Its footprint and size/layout for gas/water piping and ductwork will significantly reduce KC1000 replacement installation time. The ReCon utilizes state-of-the-art technology to easily meet highly diverse, demanding commercial and industrial hot water requirements in a compact and reliable condensing design. The durable high efficiency helical firetube heat exchanger is time tested to be impervious to thermal stress for an extended life. The all stainless steel construction maximizes longevity in the condensing application and the corrugated tubes increase effective heat transfer surface area for optimal thermal efficiencies up to 99%. Enhanced waterside flow distribution maintains constant minimum velocities across the heat exchanger; this keeps solids in suspension and greatly reduces scale dropout to maintain high efficiency performance and long life.

The advanced control system of the Recon incorporates dynamic feed-forward sensing for precise modulation of its turndown air/fuel delivery system. These controls fire the unit to accurately match load requirements and produce tight hot water outlet temperature control. Wasteful overshooting and cycling are virtually eliminated as is the need for storage tanks, mixing valves and other temperature averaging components in most applications. The set point is adjustable from 50°F to 190°F and control to +/- 4°F is easily achieved. Sidewall, through–the–roof, and sealed combustion capabilities provide broad installation flexibility. The small footprint, doorway size, and quiet operation make it ideal for retrofit. In addition to the above-added features over KC1000 system, the ReCon unit also incorporates the feedback received from service technicians and end users to provide a desired replacement unit. With its tight temperature control, high efficiency, reliability and longevity the AERCO Recon is truly unique and advanced design.

Options and Accessories

ADMS (AERCO Digital Mixing Station)
If local code mandates use of a mixing valve or for storage tank or two temperature applications with AERCO water heaters, it is recommended to use an AERCO digital mixing station. Lead-free, ASSE 107 certified ADMS is a smart water tempering system that allows temperature controlled distribution of potable hot water throughout the loop. The building automation system (BAS) ready ADMS™ can be configured with strainers, building recirculation pump and Flow/BTU monitor package to allow facilities managers to remotely monitor and control distribution water temperatures along with monitoring of flow and energy consumption.

Condensate Neutralizer Kit
Ideal for neutralizing condensate from water heaters operating on natural gas or propane.

ProtoNode Gateway
Optional accessory supports heater communication with your facilities BACnet, LonWorks and N2 systems.

Maintenance Kit
AERCO Preventive Maintenance Kits are designed to meet the preventive maintenance needs of your AERCO equipment. Each maintenance kit includes the required spare parts to perform the AERCO recommended maintenance schedules for the specified appliance.

Gas Supply Regulator

  • Non-lock-up regulators for gas pressure < 14” W.C.
  • Lock-up regulators for gas pressures > 14” W.C.
