A. O. Smith Burkay Genesis GWH-1850 in practice
The GWH-1850 is one of the Burkay Genesis circulating water heater models officially listed on hotwater.com. Its support page is titled 'Series Discontinued: A. O. Smith Burkay Genesis Circulating Water Heater GWH-1850' and the page body prints 'SERIES DISCONTINUED'. The official Genesis replacement parts list covers this model with natural-gas and LP gas valve, LP orifice and burner rows.
A. O. Smith's official pages do not print input, output, efficiency or connection ratings for the GWH line; the support page's Tech Specs fields show placeholder values and link only the parts list. Boilers.ca records the model as a discontinued DHW-only appliance (not a space-heating boiler) so the official listing is captured without inventing technical values. The 2100 size exists as GW-2100, not GWH-2100, in the same official support series.
