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,

Apart from its compact design and budget-friendly pricing, the Rheem 491125 125L Electric Hot Water System also offers an array of features, making it a remarkable selection for your home. It offers kW rating options of 1.8 or 3.6, enabling tailored energy-efficient performance for user requirements.

Additionally, the Rheem 125L system features dual handed inlets and outlets, simplifying the installation process and adding to its user-friendly attributes.

Dual Handed Inlet

The Rheem 491125 125L Electric Hot Water System is designed with dual handed inlet and outlet fittings. These features assist in simplifying the installation procedure, making it a breeze even for those who aren’t DIY experts.

The dual handed inlet and outlet fittings feature dual handed inlet, enhancing installation flexibility. This means that the hot water system can be connected from either side, depending on the site conditions. This flexibility can be particularly useful in tight spaces or unusual layouts, where installation might otherwise be a challenge.

Durable Coating

When it comes to durability, the Rheem 491125 125L Electric Hot Water System doesn’t disappoint. It features an exclusive Rheem Ultranamel® Class Y enamel, a tough and durable coating that safeguards the cylinder.

This advanced enamel protects the water heater by offering several benefits:

Choosing the Right Hot Water System for Your Home

Selecting the appropriate hot water system for your home is a significant decision. It can impact not only your comfort and convenience but also your energy bills and environmental footprint. However, with various models and types available in the market, making the right choice can be daunting.

Several factors should be considered when choosing a hot water system. These factors encompass:

  • Local water conditions

  • Area climate

  • Energy supply options

  • Installation space availability

By taking these factors into account, you can ensure that you choose a system that suits your needs and preferences.

Factors to Consider

One significant factor to consider is the hot water heater’s size. It’s crucial to ensure that the heater is sized correctly; if it’s too small, there’s a risk of running out of hot water, but if it’s too large, it could lead to unnecessarily high running costs.

Continuous flow systems are best sized based on the number of hot water outlets needed, while storage and solar systems should be sized based on the number of people living in the household. This helps to ensure that your hot water system is not only efficient but also able to meet your household’s hot water demands.

Comparing Rheem Models

Rheem offers a range of hot water systems including electric storage, heat pump, and gas models. Each of these models caters to different energy performance requirements and is suitable for varying climate conditions and household needs.

Heat-pump water heaters from Rheem, for example, provide greater efficiency and lower long-term running costs when compared to traditional electric storage hot water systems.

Rheem’s gas hot water heaters, on the other hand, are typically installed outdoors due to venting needs. They offer a different balance of initial purchase price and ongoing operating costs, with continuous flow gas models being a prevalent choice.

Installation and Replacement Process

Illustration of the installation process of a hot water system

After selecting your Rheem 125L hot water system, the subsequent step is initiating the installation process. This includes standard dual inlets and outlets, as well as standardized connections for power and water, ensuring a straightforward replacement of the existing system.

The process of installing the Rheem 125L electric storage hot water system usually takes between 2-4 hours, depending on the complexity of the specific installation scenario. This ensures that you’ll have your new system up and running in no time at all.

Removing the Old Unit

Before the new system can be installed, the old hot water system needs to be removed. An electric storage hot water system typically needs to be removed and replaced after 10-15 years of service due to age or malfunction.

There are several disposal options for the old hot water system. These include:

  • Recycling centers

  • Personalized garbage services

  • Local landfills

  • Junk removal services

Each of these non commercial options offers a different level of convenience and environmental responsibility.

Recycling centers may offer monetary compensation for valuable components like brass, copper, and steel from old water heaters. This not only makes disposal more convenient but can also help offset some of the costs of your new system.

Electrical Connection

The Rheem 125L electric hot water system requires a 1x1.8kW element for heating, ensuring that you have a steady supply of hot water whenever you need it.

For those looking to maximize their energy efficiency, a timer can be installed with the system. This allows you to maximize the use of PV-generated power, potentially reducing your household running costs.
