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,

Sleek Design Meets Durability

While the performance of the Rheem Stellar 315L is impressive, its design is equally commendable. Here are some key features of its design:

So, with the Rheem Stellar 315L, you’re not just investing in a hot water system—you’re investing in a reliable, long-lasting solution to your hot water needs.

Installation Insights: Setting Up Your Stellar 315L

While the Rheem Stellar 315L offers a plethora of features and benefits, they can only be fully realized with proper installation. The process of setting up your new hot water system involves crucial steps that need professional handling—from choosing the right installer to safely removing your old system.

Let’s explore these factors to guarantee you’re thoroughly prepared for the installation of your Rheem Stellar 315L.

Choosing the Right Installer

Selecting a professional installer for your Rheem Stellar 315L is a decision of utmost importance. A certified and licensed installer ensures that the installation complies with standards and safety protocols, and is essential for the safe operation of your hot water system. These professionals possess the training, knowledge, and skills necessary to meet safety standards and correctly implement safety features.

In addition to ensuring a safe and successful installation, choosing a licensed company that provides insured work is crucial to maintaining the system’s warranty. This not only ensures the safety of the installation but also protects you from potential risks and liabilities.

So, when it comes to installing your Rheem Stellar 315L, remember to entrust the job to a professional for the best results.

Removing Your Old System

Before you can enjoy the benefits of your new Rheem Stellar 315L, there’s the matter of removing your old hot water system. This process involves draining the tank, disconnecting pipes, and managing the weight of the unit—tasks best left to a professional installer.

Although it may appear as an extra cost, the expense involved in the professional removal and disposal of your old hot water heater is a valuable investment. It ensures the safe and efficient removal of your old system, clearing the way for your new Rheem Stellar 315L. So, as you plan for the installation, remember to factor in the removal of your old system—it’s a crucial step towards upgrading to a better hot water experience.

Maintenance Must-Knows for Longevity

While the Rheem Stellar 315L is designed for durability and reliable performance, regular maintenance is key to ensuring it operates at peak performance. It is advisable to hire a licensed technician to service your Rheem Stellar 315L every five years. Regular servicing not only keeps your system running smoothly but also helps identify potential issues early, preventing costly repairs down the line.

One of the key maintenance tasks for your hot water service is checking the tempering valve every 12 months to confirm it is operating correctly. This valve is vital for delivering water at the correct temperature and pressure, ensuring your hot water experience remains uncompromised.

Another good practice is to periodically flush sediment from the tank of your Rheem Stellar 315L. Over time, sediment can accumulate in the tank, leading to inefficiency and potential damage. Flushing out this sediment can help prevent these issues, extending the lifespan of your system.

And don’t forget to insulate the pipes connected to your Rheem Stellar 315L—this simple step can reduce heat loss and enhance the overall efficiency of your hot water system, including heat pumps and the heat pump system.

Expand Your Options: Accessories and Add-ons

The Rheem Stellar 315L itself is a sturdy hot water system, but are you aware that its performance can be further improved? By pairing it with a solar hot water heating system, you can harness the power of the sun to heat your water, adding a layer of eco-friendliness to your hot water experience. The Rheem Stellar 315L even includes a boost feature to ensure hot water availability on cloudy days when solar energy may be limited.

Another option is to incorporate gas continuous-flow technology in gas water heaters, using natural gas as the fuel source. This allows the Rheem Stellar 315L to provide hot water on demand, ensuring you never run out of hot water. Whether you’re looking to optimize energy use with solar power or prefer the convenience of continuous-flow technology, the Rheem Stellar 315L offers the flexibility to expand your options and customize your hot water experience.

Customer reviews provide insight into the actual performance of a product, and the Rheem Stellar 315L is not an exception.
