 Trustindex verifies that the original source of the review is Google. I highly recommend Adam. He was able to come out on the same day I contacted him to diagnose an issue with our hot water system. He explained the problem clearly and provided me with different options and information regarding replacement. Once I decided on the replacement, he had the new system installed within just three days of my initial request. The whole process was quick, professional and straightforward. Very happy with the service!

 Trustindex verifies that the original source of the review is Google. ⭐⭐⭐⭐⭐ I couldn’t be happier with the service from Adam at AJW Plumbing, Gas & Air. Even over the weekend, he responded quickly to my enquiry, which was really impressive. The quoting process was incredibly easy. I simply sent through a few photos and received a clear, competitive quote without needing an initial site visit. Adam was professional, friendly, and easy to deal with from start to finish. The installation was completed to a high standard, and he left everything neat and tidy when the job was finished. Excellent communication, quality workmanship, and great customer service. I wouldn’t hesitate to recommend Adam and AJW Plumbing, Gas & Air to anyone looking for a reliable plumber. Thanks again!

Gas Storage Hot Water Systems Installations

Storage systems have long been the most popular type of hot water systems installed in Australian homes. Because storage technology has been around for a long time, it offers proven reliability. Plus, there are many capacity options available to suit different usage needs.

Both electric and gas storage systems have similar advantages and disadvantages. Storage systems have the lowest upfront cost of all hot water system types. Doing a ‘like for like’ replacement of an existing storage unit will generally keep the installation cost low. Hiring a skilled hot water system installer ensures the best performance and longevity of your system.

Continuous Flow Hot Water Installations

Along with being efficient and never running out of hot water, one major advantage of a continuous flow hot water system is their compact size. These units are generally wall-mounted and usually come out from the wall less than 25cm. This makes them a great option for properties with limited outdoor space. A professional hot water system installer can help you choose the right system for your home.

When a tap in the home is turned on, cold water flows into the hot water system’s pipe at the bottom of the unit. An inbuilt sensor automatically detects the water flow and then ignites a gas burner.

The hot exhaust gases from the burner rise up and warm the water flowing through a heat exchanger. The water is heated to approximately 50 degrees. Then it flows out of a pipe at the top of the unit to the outlet. For best results, ensure the system is installed by a hot water system installer.

Heat Pump Hot Water Installations

A heat pump hot water system can be up to 5 times more efficient than standard hot water technologies. There is also a significant decrease in carbon footprint. Finally, because heat pumps store hot water inside of a tank, hot water can be enjoyed at mains pressure. This is the perfect solution for your hot water system replacement. Remember to consult with a hot water system installer to determine the best setup for your needs.

Frequently Asked Questions

What types of hot water systems does AJW Plumbing Gas & Air install in Mandurah and Rockingham?

We install the full range of hot water systems across Mandurah, Rockingham, and the surrounding suburbs — including electric storage, gas storage, continuous flow (instantaneous) gas, solar hot water, and heat pump systems. Our licensed plumbers can advise on the right technology for your household size, budget, and energy goals during a free consultation.

What warranty should I expect on a new hot water system?

Most hot water systems come with a tank or cylinder warranty of five to ten years, with parts and labour cover typically ranging from one to two years depending on the brand and model. Brands such as Rinnai, Rheem, and Bosch offer comprehensive warranty programmes on their premium ranges. Our team installs systems from leading brands and can explain the exact warranty terms before you commit.

How much does a hot water system cost to install in Mandurah and Rockingham?

Installation costs vary based on system type and complexity. As a general guide, electric storage systems start from around $900–$1,400 installed, gas storage from $1,200–$2,000, continuous flow gas from $1,500–$2,500, and solar or heat pump systems from $2,500–$4,500 or more depending on the size and brand. Government rebates are available on heat pump systems in WA, which can significantly reduce the upfront cost.

How do I choose the right hot water system for my home?

The right hot water system depends on several factors: the number of people in your household, your current energy source (gas or electric), your roof orientation if solar is an option, and your budget for upfront installation versus long-term running costs. Heat pump and solar systems have higher upfront costs but significantly lower running costs over time. Our team can walk you through a comparison and recommend the best fit for your home.

How long does hot water system installation take?

Most standard hot water system installations take between two and four hours. A straightforward like-for-like replacement — swapping an old electric unit for a new one of the same type — is typically completed within two hours. More involved jobs, such as switching fuel type or upgrading to solar or heat pump, may take up to half a day depending on site conditions and any additional pipework required.
