How do solar hot water heaters work?

If you live in Sydney and most parts of Australia, using solar energy to heat hot water is an effective way to use our abundant sunshine saving money on your household bills and reducing your greenhouse gas emissions.

Solar water heaters work by absorbing energy from the sun’s rays in the roof mounted solar collectors and transferring this to heat water stored in the tank.  Ground mounted direct systems rely on an inbuilt circulator to push the water through the system, whereas roof mounted systems rely on a natural ‘thermosiphon’ effect. Water passes through the solar collector where it is heated, then moves out of the collector and into the tank. The tank gradually gets hotter until the water reaches its maximum stored temperature.

Collector panels should be located on the roof, preferably on a north-facing section at an angle of around 35 degrees above horizontal, and free from any shading. Angles as low as 15 degrees may be acceptable, but winter performance of the system will be decreased and more panels may be needed to accumulate enough power.

The location of the storage cylinder either on the roof or at ground level should be close to the main hot water outlets (usually in the kitchen and bathroom). All solar systems come with a gas, off-peak electric or solid fuel booster to supply hot water during periods of low sunshine.

To avoid wasting fuel and money, it is important that booster switches be fitted with timers or easily accessible on/off switches.

Indirect systems such as solar heat pumps, use a special heating fluid, rather than water to absorb heat from the collectors. The heat is transferred to the water in the tank via a heat exchanger.

The benefits of switching to solar hot water

Switching to solar hot water offers both excellent environmental and financial investments.

Solar hot water can significantly reduce fossil fuel energy use and consequent pollution and greenhouse gas emissions. Not only are you helping the environment by installing a solar hot water or heat pump system, you could also enjoy substantial savings on your household hot water energy use of up to 73%.

Types of Solar Hot Water Systems

Roof Top Solar Hot Water System

rheem roof top solar system

If you have ample free roof space, then you are perfectly placed for solar options. Roof top solar for example, work by mounting the solar panels and storage tank together on the roof. The collectors draw the sun’s energy into fluid in the solar collectors, then the heated fluid circulates the adjacent storage tank.

Rheem’s roof-mounted solar hot water systems have storage cylinders made of either quality stainless steel or vitreous enamel coated mild steel. Stainless steel is prominent in most kitchens for its purity, aesthetics, ease of maintenance and corrosion resistance. Stainless steel acts as a natural barrier to corrosion, whereas vitreous enamel coated water heaters require a sacrificial anode. The outer casing of Rheem’s stainless steel solar range is constructed from weatherproof COLORBOND® steel. Rheem offer a choice of four contemporary COLORBOND® steel colours with their modern design roof mounted range.

Rheem’s roof-mounted storage systems come with either 5, 7, or 10 year cylinder and collector warranty depending on the model you choose.

Split Solar Hot Water System

If you have limited roof space or you prefer a more streamline look, then a split loline solar water heater may be the best solution. Whilst the solar panels are mounted on the roof, the storage tank is located at ground level.

Solar water heaters work by absorbing energy from the sun’s rays in roof mounted solar collectors and transferring it to the water stored in the ground mounted storage tank. Ground mounted systems employ inbuilt pumps to push the fluid through the system. The split design of the system reduces the roof’s structural load, as only the low profile solar collectors are installed on the roof.

Which system you choose will depend on where in Australia you live, which way your home faces and even the pitch of your roof. So it’s important to talk to one of our solar hot water specialists to determine what type of hot water heater is ideal for you.

Heat Pumps

solar heat pump

Solar heat pumps deliver hot water by efficiently by utilising a free and abundant source of energy – the heat that is in the air around us.

Refrigerant vapour compression technology enables the heat pump to intensify this heat, which is used to produce hot water. Heat pumps are more efficient during warmer months, and will operate for less hours during the day than in colder months of the year.

Because heat pumps do not require solar collectors, they are perfect where roof space is limited. Additionally, since they utilise the same plumbing and electrical connections as an electric water heater, solar heat pumps are an ideal upgrade from a standard electric water heater.

Which heat pump solar system you choose will depend on where in Australia you live, which way your home faces and even the pitch of your roof. So it’s important to talk to one of our Sydney solar specialists to determine what system is ideal for you.

Solar Hot Water System Prices

The price to switch to solar hot water or install a new solar hot water system varies from property to property.  Over the phone our solar experts can ask you a series of questions that will enable them to give you a price estimate. We then recommend undertaking a site inspection of your property where we will be able to give you a firm quote.

Solar rebates and Government incentives

The higher installation costs of switching to solar hot water are compensated by longer-term savings and the reduced impact on the environment. A solar hot water system can substantially reduce your power bills by providing 65 to 80 per cent of your hot water free of charge. The Federal Government solar incentives can reduce your initial investment making the switch to solar hot water not only a good choice for the environment but also for your pocket.

The Federal Government encourages people to switch to solar hot water and offers generous incentives to help you make the transition. The incentives come in the form of Small Scale Technology Certificates (STCs), which can be sold to recoup a portion of the cost of purchasing and installing your new solar system.

By installing a solar water heater or solar power system on your property, you may be eligible for STCs. These STCs can be used to reduce the purchase price of your new system and can often save you thousands of dollars.

For a solar hot water system, each STC represents 1 megawatt hour (MWh) of electricity displaced over a 10 year period. The number of STC’s created varies with the size and model of solar water heater and the region (or zone) in which the unit is installed. The value of an STC is not fixed and varies depending on market factors.

Once you install a solar water heater the STCs produced can be traded and sold on the open market. You can assign the right to create your STCs to your installer who will pay you the value of the STCs as an upfront discount on your system.

Contact us for more information about STCs and how you can take advantage of them when purchasing a new solar hot water system.
