Condensing Water Heaters for Commercial Applications
HDC 1500i / HDC 1500e
Versatile, technologically advanced temperature priority hot water
Innovation
Rinnai’s unique condensing technology incorporates two heat exchangers to achieve optimum water heating generated from every cubic metre of Natural Gas or LPG. These compact wall mounted water heaters capture residual heat from its flue gases and transfers it into the water being heated.
Energy efficient
HDC1500i/e 104.5% net efficiency*
