Rheem Continuous Flow/Instantaneous Hot Water Heaters

Since coming into the market over 20 years ago, continuous flow hot water systems including Rheem continuous flow products, have become very popular in the market place.

Rheem continuous flow hot water systems work differently than other Rheem gas hot water systems. This is because the process by which they heat the water is continuous and is on demand when the hot water is needed. On the other hand, other Rheem hot water systems heat the water and then store it until it is needed for use. So the key benefit of continuous flow Rheem hot water systems is the ability to produce on demand hot water. This means that you will never run out of hot water!

With their high efficiency, great flow rates, and compact size these Rheem instantaneous hot water systems are being installed in family homes all over Australia.
