Rinnai

Founded in 1920 by Hidejiro Naito and Kanekichi Hayashi, Rinnai quickly established a tradition of improvement. They began with pressurized oil stoves in Japan and expanded into gas appliances, like stoves, ranges, and heaters, by the 1930s. Since 1964, Rinnai has been known for efficient water heating. Their 100+ year history reflects a commitment to quality, safety, and support.

 

Water Heaters

Rinnai's high-efficiency tankless water heaters are designed for large homes, providing reliable hot water, reduced utility bills, and eco-friendly operation. They deliver 5 gallons per minute, supporting multiple showers simultaneously. For small to medium homes, Rinnai offers affordable, compact, non-condensing models that save space and consistently provide hot water.

Boilers

Rinnai boilers provide high efficiency with condensing technology for optimal performance and minimal energy waste. With AFUE ratings of 95% or higher, they are ENERGY STAR certified and meet ultra-low NOx emissions standards. User-friendly features include Bluetooth setup via the Rinnai Central App and a proportional valve for simultaneous heat and hot water delivery, making them a versatile and reliable home heating choice.

HVAC

Rinnai HVAC products are known for high efficiency, advanced technology, and flexible installation options. Their hydronic air handler systems offer heating and hot water simultaneously, integrating with tankless water heaters and boilers. Suitable for new and retrofit applications, these systems eliminate the need for ductwork. Rinnai's direct vent furnaces use modulating technology for consistent comfort and energy efficiency. With user-friendly controls and Wi-Fi thermostat compatibility, Rinnai provides reliable heating solutions for modern homes.
