Rheem, PRO+G40-40N-RH62

Rheem Professional Classic Plus Series 40-Gallon Natural Gas Water Heater – Atmospheric Vent, 40,000 BTU

The Rheem PRO+G40-40N-RH62 is a 40-gallon, tall-profile, atmospheric vent water heater engineered for residential use. Designed with a 40,000 BTU/hr low-NOx burner and push-button pilot ignition, this unit delivers a recovery rate of 40.4 gallons per hour at a 90°F temperature rise, supporting consistent hot water delivery in medium-demand household applications.

This model features a glass-lined steel tank with anode protection, factory-installed temperature and pressure relief valve, and maintenance-free air intake system. It operates without filters or external components, minimizing service intervals and simplifying installation in standard vertical B-vent configurations.
