Solar hot water products FAQs

With solar hot water you’ll not only save money, but you’ll help our environment too. According to the Australian Government, water heating is the largest single source of greenhouse gas emissions from the average Australian home, accounting for around 28% of home energy use, excluding the family car†

It can also reduce your energy bills by using the sun’s energy to heat your water.

In fact, solar hot water systems are so good for our environment that Renewable Energy Certificates and government rebates exist to make it easier and more affordable for you to install solar hot water.

Our solar hot water systems come fully installed. If your home falls outside our standard installation guidelines, you will be advised of any additional costs prior to installation.

Solar hot water systems work by using heat from the sun to warm your water.

Typically, heat is absorbed by your solar collectors, which are mounted on the side of your roof that has the most exposure to the sun (generally the north facing area of your roof). The heat directly warms the water in the collector and flows back to the storage tank pre heated.

Our solar water systems are split systems. This means your solar collectors are located on the roof of your home, while your tank is mounted on the ground.

Origin's Solar Systems are supplied with hi-efficiency solar panels which are specifically designed to minimise heat loss and maximise efficiency.

Benefits:

• High performance anodized selective surface – long lasting and high performance.
• High efficiency collectors for improved solar contribution.
• Aluminium fin with copper tube design for maximum thermal conductivity and efficiency in collecting solar energy.
• Aluminium casing - corrosion resistant and ideal for coastal areas.

Solar collectors can be installed onto a roof pitch of up to 30 degrees, with optimum orientation towards the north. Additional charges may apply for roof pitches of greater than 30 degrees. We are unable to install on homes with a roof pitch of greater than 45 degrees.

Shading of solar collectors will reduce the available contribution by the sun for water heating and therefore reduce the efficiency of your solar water heater system.

All our solar hot water systems are fitted with a gas or electric booster as a ‘back up’ to ensure your water is always heated to the correct temperature - even when the sun isn’t shining.

Our solar hot water systems are fitted with solar collectors designed for maximum heat absorption, so you’ll have hot water on tap, all year round.

The size of your hot water storage tank depends on the type of system you order – either gas or electric. We supply the following sized hot water storage tank for each system:

• Gas continuous flow boosted solar hot water split system: 250 litre tank
• Gas storage boosted solar hot water split system: 170 litre tank
• Electric boosted solar hot water split system: 315 litre tank
• Electric boosted solar hot water split system: 400 litre tank
• Heat Pump hot water system: 250 litre tank

The Australian Government’s Solar Hot Water Rebate Program encourages consumers to switch to alternative hot water technologies by helping with upfront costs. Because electric storage hot water systems generate the largest amount of greenhouse gas emissions, the rebate eligibility criteria includes that a solar hot water system must replace an existing electric hot water system.

The solar hot water system must also be a solar or heat pump hot water system that is eligible for at least twenty Renewable Energy Certificates (RECs) at the time.

Our electric boosted solar hot water split systems meet the above criteria and qualify for the Australian Government Solar Hot Water Rebate Program. This means that if you are eligible to receive the Australian Government rebate, you will receive the maximum rebates you're entitled to under the scheme. So even if your current system is only a few years old it still pays to replace it with solar - you'll not only save money on your energy bills, but you’ll help our environment, too.

Yes, should your existing electric or gas hot water system be located inside your home (in a cupboard or be in a ceiling gravity feed) we are able to offer you a solar hot water product.

An Origin split system solar water heater allows you to enjoy all the benefits of our advanced solar technology, without a tank mounted to your roof. With an Origin solar hot water system, your solar collectors are located on your roof, while your tank is installed out of sight at ground level.

Roof mounted solar hot water systems can be quite heavy and require the roof of your home to be structurally sound to support this extra weight. Given the weight of the tank, in some circumstances a crane may be required to lift the tank onto the roof, which can add to your installation costs.

With Origin solar hot water, there’s no need to provide extra support to your roof.

If your roof is flat, we’ll provide frames to raise your solar collectors. This is included in our price for a flat roof installation.

The installation of your solar hot water system takes less than one day. It will take approximately two to four weeks to process your order, from order placement to installation (excludes post-installation rebates where applicable).

After you order either online or over the phone, we’ll arrange a time and day for installation that’s convenient for you.

Yes, should you have an electric hot water system, we can offer you a gas boosted solar hot water system.

The best way to obtain maximum performance from your solar hot water system is to make efficient use of hot water in your home. Where possible, do jobs that require hot water early in the day. This allows the remaining water in your tank to be reheated by the sun and reduces the supplementary gas or electric boosted heating period that’s required.

Yes. There will be no change to your water pressure or supply after you install your Origin solar hot water system.

Solar hot water collectors use heat from the sun and/or air to directly heat water.

Solar photovoltaic (PV) electricity panels use sunlight to generate direct current which can then be converted to alternating current and used within the home or to feed power back to the electricity grid.

Solar hot water collectors can’t be connected to the electricity grid and solar PV panels can’t be used to heat water - they are different forms of technology and are not linked.

Yes - all our solar hot water systems have frost protection.

The life expectancy can vary considerably however Origin solar hot water systems are covered by a 5 yr warranty.

Our hot water tanks are lined with vitreous enamel, specifically designed to reduce corrosion and suitable for all water conditions.

Heat pumps work like a solar hot water system but without solar collectors mounted on your roof. Heat pumps transfer the heat in the air outside of the unit to the water stored inside the heater through a heat exchange system. In the case of heat pumps, "heat" is a relative term as they will still work in cold conditions - at least -5 degrees Celsius, so it will still be generating hot water for you during winter nights

Currently Origin offers electric heat pump systems for replacement of electric storage systems only.

No. A Dux Airoheat is designed to be installed outside so that it can draw in the surrounding air and capture the heat energy for water heating.

The more modern heat pumps can operate very efficiently in most climatic conditions through out Australia.

• If you do not have a north facing roof – optimum efficiency from a solar water heater is obtained by orienting the panels towards north. This maximises the amount of water heated by the sun in solar collectors. A heat pump does not have collectors on the roof to heat water efficiently, but rather draws heat energy from the surrounding air.
• If your roof (and therefore potential solar collectors) are shaded between 10.00 am and 3.00 pm – this is the best time of day for solar contribution towards your water heating. Shading reduces the efficiency of a solar water heater. A heat pump does not require direct sunlight to efficiently heat water but rather draws heat energy from the surrounding air.
• A heat pump is simple to install. A heat pump can simply be located in the same spot as your old electric system (provided it is outdoors) with very little change to your plumbing. This helps keep down the cost of installation.
• A heat pump can heat during the day or during the night - a heat pump does not require direct sunlight to heat water but rather draws heat energy from the surrounding air. It is most efficient during the warmest part of the day.
• A heat pump does not require solar collectors on your roof. If roof space is at a premium in your home or you do not have suitable north, north east or north west facing roof space for solar collectors a heat pump is a great alternative to solar hot water.
• Heat pumps have a relatively fast recovery or re-heat time. If you ever use all the hot water in the tank, the water can be heated to a useable temperature in less than 3 hours.
• If you are contemplating installing a photo-voltaic (PV) system on your roof to generate electricity. A heat pump can reduce your electricity consumption and therefore the electricity draw on your PV system meaning you can send more electricity back to the grid. It also does not compete for roof space with the PV collectors as a heat pump does not require collectors but rather draws heat energy from the surrounding air.

The Government’s Mandatory Renewable Energy Target (MRET) supports the reduction of Australia's greenhouse gas emissions by increasing the proportion of Australia's electricity that is derived from renewable energy sources. This is achieved through an innovative market-based certificate trading scheme.

The commodity in this market is the Renewable Energy Certificate (REC) - each REC represents the equivalent of one megawatt hour of electricity generation from an accredited renewable energy source. For solar hot water systems, each REC represents the displacement of one megawatt hour of electricity generation by solar energy.

Owners of water heaters that use renewable energy may be able to create and sell RECs to help offset the cost of installing renewable energy technologies in the home.

Both our gas and electric boosted hot water systems are eligible for RECs. We make it easy for you - all our prices are inclusive of the REC rebate. This represents the value of the RECs we estimate will be created by your system after installation which you sell to us at the time of purchasing your Origin solar hot water system.
