From our customers


These guys are great and their service is outstanding. My hot water failed and the next day I rang at 8.45am to see if they could help and they had a new system in stock and the same day they came out at 1.00pm and had it working at 2.30pm with a complete upgrade with new valves and pipework and they even put a drain in for the overflow. Josh and Shane who came out were not only friendly and helpful but are super professionals and know exactly what to do and I can't recommend these people highly enough. The price they quoted me was not only competitive but the work was outstanding. 5 plus!

Highly recommend you purchase your hot water system from Installed today. I obtained 3 quotes from local plumbing stores and a further 3 quotes from online retailers. Installed today was the most competitive. I ordered at lunchtime and by 9am the next day my new hot water system was delivered. Under 24hrs wow!. The delivery person even wheeled it around to the side of the house for me. Thanks for providing such a competitive price and the fast service was a bonus. You put bunnings, tradelink and Reece to shame.

Sean phoned to confirm what time he would be on-site to remove and install the new Rheem Hot water cylinder. He arrived on time and set about removing the old cylinder and installing the new . He worked non stop with the installation which was completed to a very high standard. He cleaned up any mess and after loading the truck he ran through the install showing me what did what and if I had any problems to let the company know. It was good to see a conscientious tradesman at work.Thanks Sean, a great job

Josh and Brandon arrived on site and explained what they were going to do. Took minimal time to do the job and explained the warranty and maintenance procedures before they left. They gave me peace of mind by stating they would return within the 10 year warranty period if any trouble occurred with the system. I found both boys to be polite and courteous and took the time at the end to show what was replaced and how to operate it. From start of the booking process at 7:30 am to the completion of the job at 3:00 pm the same day,

Adjustable Thermostat Settings

Adjustable thermostat settings on the Rheem 491160 ensure that performance is always optimized.

The twin element feature complements these settings, providing a faster heating response that’s critical when multiple showers and appliances demand hot water at once.

Together, these features form a powerful duo that optimizes both energy consumption and hot water availability, delivering a tailored hot water experience that’s both efficient and reliable.

Scheduling Hot Water Availability

Efficiency meets innovation with the scheduling capabilities of the Rheem 491160. Using a timer, the system can be programmed to heat water only when needed, avoiding the unnecessary energy consumption and costs associated with reheating during standby periods. By scheduling the heating to occur during off-peak times, households can capitalize on lower electricity rates, further enhancing the economic operation of the system.

With digital timers providing remote access, adjusting heating times to align with your daily routine has never been easier, ensuring hot water is ready just when you need it. Considering that the average water tank requires about 60-120 minutes of active heating daily, plus additional time to heat the full tank, setting the timer accordingly guarantees that hot water is always at the ready when required.

Comparing Rheem 491160 with Other Rheem Models

Comparative analysis of Rheem 491160 with other Rheem models for high hot water demands

In the realm of hot water systems, the Rheem 491160 stands out with its distinctive features that cater specifically to smaller household needs.
