Reliable, efficient hot water on demand -- supplied and installed by a certified gasfitter
The Rheem Integrity is one of the most trusted continuous flow hot water systems available in New Zealand. Rheem has been a household name in water heating for decades, and the Integrity range represents their commitment to reliability, efficiency, and value. For Auckland homeowners looking for a proven alternative to the Rinnai Infinity, the Rheem Integrity delivers consistent performance backed by strong local support and parts availability.
Like all continuous flow systems, the Integrity heats water on demand as it passes through the unit. There is no storage tank, no waiting for a cylinder to reheat, and no risk of running out of hot water during busy mornings.
The Rheem Integrity range comes in several sizes, rated by their maximum flow rate in litres per minute at a 25-degree temperature rise:
The litres-per-minute rating tells you how much hot water the unit can produce at full capacity. In winter, when the incoming water temperature drops, the effective flow rate is slightly reduced as the unit works harder to reach the set temperature. A correctly sized unit accounts for this seasonal variation.
Rheem backs the Integrity range with solid warranty coverage. The specifics vary by model, but typically you can expect a 10-year warranty on the heat exchanger (the most critical component) and a 3-year warranty on parts and labour. This is competitive with other brands in the market and reflects Rheem's confidence in the product's durability.
Both the Rheem Integrity and Rinnai Infinity are excellent continuous flow systems and either will serve an Auckland home well. Rinnai holds a larger market share in New Zealand and has a wider range of models. Rheem counters with strong local support, competitive pricing, and a brand that New Zealand homeowners have trusted for generations.
The choice between the two often comes down to availability, pricing at the time of purchase, and personal preference. We install both brands regularly across Auckland and can advise on which unit best suits your home's specific requirements.
Installing a Rheem Integrity requires the same fundamentals as any continuous flow system. You need a gas supply (natural gas or LPG), adequate flue clearances from windows and boundaries, and a standard 230V electrical outlet near the unit. The Integrity mounts on an external wall, keeping the installation clean and out of the way.
All gas installations must be completed by a registered and certified gasfitter. We handle the full process from sizing and quoting through to installation, gas certification, and council compliance where required.
The Rheem Integrity is available in both natural gas and LPG configurations. If your Auckland property has a natural gas connection, this is typically the more economical choice for ongoing running costs. For homes in areas without reticulated gas -- common in parts of East Auckland, the North Shore fringe, and rural Auckland -- an LPG model connected to gas bottles is a practical and equally effective solution.
Rheem has been operating in New Zealand for decades. Their parts supply chain is well established, meaning replacement components are readily available if needed down the track. The brand has a strong reputation for reliability, and Auckland plumbers and gasfitters are thoroughly familiar with the product. For homeowners across suburbs like Mt Wellington, Pakuranga, Henderson, and Takapuna, the Rheem Integrity is a proven, no-fuss choice for continuous flow hot water.
