Rinnai HDC32E75 75C Heavy Duty External Condensing Continuous Flow Hot Water Heater

What is High Efficiency Gas Condensing Technology?
In standard continuous flow systems, heat and water vapour escape as exhaust at temperatures up to 200°C. Rinnai’s condensing units use a dual heat exchanger system to maximize energy use. The first exchanger transfers heat from the gas combustion process to the water, while the second exchanger reclaims heat from the flue exhaust gases and uses it to preheat the incoming cold water. As exhaust vapour cools below its condensation point, it forms liquid condensate, releasing additional heat that is also transferred to the water. This system lowers flue temperatures to around 35°C and ensures minimal energy is wasted.

External Installation: The outdoor vent cap is manufactured in a durable and corrosion resistant plastic to withstand the harsh Australian climate when employed in demanding commercial applications.

Revolutionary fuel sensing technology removing the need for separate models for Natural Gas or LPG. Historically gas continuous flow water heaters required time consuming modifications to change to operate on either Natural Gas or Liquid Petroleum Gas. The sophisticated gas control valve assembly makes this a thing of the past. A simple parameter change on the controller is all that is needed and you are ready to go.
