Bradford White AeroTherm RE2H heat-pump water heater (50/65/80 gal): quick sheet

Covers: AeroTherm RE2H50S, RE2H65T, RE2H80T (first generation, installation manual dated 2022) and suffixes such as -1NCWT / -1NCTT; G2 RE2HP65 is a newer build. Also sold under the Jetglas label.

Hybrid electric tank: a top-mounted heat pump with 240/208 V backup elements, Vitraglas-lined steel tank, washable top air filter, condensate drain. The control panel shows water-heater, tank, need-to-assess and heat-pump codes and lets you see thermistor and component status. Deep diagnostics: heat pump water heater field service manual.

Safety first

Turn off the breaker and verify zero volts before touching elements, thermostats or terminals; 240 V tank and tankless units can be lethal.
Never energize an element without water around it (dry fire).
Do not remove or plug the T&P relief valve; its discharge line must run to a safe spot.
Sealed refrigerant system is blocked: refer to an EPA 608-certified technician.

How it works

In heat-pump modes a compressor moves heat from room air into the tank; the elements run only in hybrid/electric modes or high demand.

Air passes a washable filter at the top; condensate drains from a pan through a hose to a drain or pump.

Thermistors on the tank and in the heat pump feed the control; codes are read on the panel.

Diagnostic guides for this appliance

Guide · Water Heater

Heat-pump (hybrid) water heater: slow recovery, noise, errors

Hybrids need enough room air and a clean air filter, a working condensate drain and the right mode. Many complaints are mode settings or a dirty filter. Refrigerant faults are sealed-system work.

Guide · Water Heater

Tankless water heater descaling (flush)

Scale insulates the heat exchanger, causing overheat codes and fluctuating temperature. Flush with a pump and descaling solution through the isolation valves.

Guide · Water Heater

Hot water recirculation pump problems

Check timer/settings, check valves, air in the loop and the pump itself. On tankless units with built-in pumps, a recirculation code may point to air or a leak in the loop.

Rheem / Ruud / Richmond atmospheric gas tank with electronic thermopile control: quick sheet (diagnostic and electrical side)

Residential atmospheric-vent, standing-pilot gas tanks (Performance, Performance Plus, Professional Classic and the Ruud/Richmond equivalents, typically XG-prefix model numbers) built with the Guardian-style FVIR combustion chamber and a self-powered electronic gas control (White-Rodgers or Honeywell, depending on year). Power-vent and condensing Rheem tanks use different controls and are not covered here. Gas-side work (gas control, pilot, burner, thermopile replacement, venting) is diagnosis-and-refer only.
