Why Upgrade to a More Energy Efficient Hot Water System?

The humble hot water system might not be something you discuss over dinner parties, but it’s an important part of every home. It accounts for around 25% of household electricity use and produces 23% of greenhouse gas emissions. With that in mind, you should consider upgrading your old electric storage tank or solar hot water system to a more energy efficient alternative. Here at Brisbane Hot Water Group, we have the experience and expertise to help you find a new, energy-efficient hot water system that meets your lifestyle, budget and property requirements.


We work with the industry’s leading brands including Rheem, Thermann, Dux and Envirosun and offer a range of hot water services, from system installations to repairs and replacements. Whether you’re looking for an electric or gas continuous flow system, we can help you find the right solution to suit your lifestyle and budget.

Our team of highly experienced and qualified plumbers will conduct a comprehensive inspection of your property before installing any hot water system. Then we’ll advise you on the best system type for your situation and provide a no-obligation quote. We’ll then arrange for a time to suit your schedule to install your new hot water system.

The type of hot water system you need depends on how much you use your bathroom and kitchen, your roof space and aspect, and your electricity tariffs (off-peak or economy). We have 5 main styles of hot water systems to choose from – electric storage, gas, solar, ground-mounted solar and heat pump. We’ve compared their purchasing costs, running costs and energy usage to help you make the best choice for your home.

Electric storage systems are the most common style of hot water system in Australia and store heated water in an insulated tank until it’s needed. This provides instant hot water, but the system is limited by its storage capacity.

Gas hot water systems are more efficient and cost-effective than electric systems and are available in both natural gas and LPG models. They are suitable for most homes and are very versatile. They are suitable for gas or electric heating appliances and offer a greater range of operating temperatures than most other systems.

Heat pumps use a small amount of electricity to move the heat from the air to the hot water tank, then use another small amount to reheat the water when required. This is the most environmentally friendly and efficient way of producing hot water in Australia.

There are a number of rebates available for hot water systems in Australia, depending on where you live and what kind of system you have installed. The ACT has a rebate for ActewAGL customers, NSW has the Energy Savings Scheme and Victoria offers incentives through the Retailer Energy Productivity Scheme.
