Booster water heaters are designed to raise incoming hot water temperature to the 180°F required by commercial dishwashers and sanitizing applications. Our electric booster selection includes models from AO Smith and Rheem engineered for reliable, continuous operation in restaurants, hotels, and healthcare facilities. These compact units install inline with your existing hot water system and deliver the high-temperature output needed to meet health code requirements.

Natural gas commercial booster heaters use gas-fired BTU input to rapidly raise water temperature to the 180°F level required for commercial dishwasher final-rinse and sanitizing applications. AO Smith BTR gas booster models in this category offer high recovery rates and reliable operation for commercial kitchens where gas service is available. Both ASME and non-ASME configurations are stocked at Wallingford Sales for fast delivery.
