93%-Efficient Tankless Water Heating

Key technology in the N-0841MC hybrid condensing unit is the Hybrid Super Heat Exchanger, which is essentially two heat exchangers fused into one. The primary heat exchanger is copper; a secondary heat exchanger is made of stainless steel. The stainless-steel component captures residual heat from the exhaust to preheat incoming water before it runs through the main copper heat exchanger. This helps increase the operating efficiency well above the 60% of some tank-type water heaters. The N-0841MC heaters are also dressed with stainless-steel shell casings to give them a unique and aesthetically appealing look. Noritz America Corp., www.noritz.com
