Assessing Your Solar Water Heater Needs
The first step in exploring solar hot water options is understanding your household’s daily needs. The Department of Energy’s tests suggest an average three-person family uses 64.3 gallons per day.
The water is usually heated from a temperature of 15°C to 58°C. For households using natural gas, this equates to roughly 0.4105 therms/day. If you are using electricity, it’s about 12.03 kWh per day.
These numbers, however, are based on averages and may not be accurate for your specific situation. Factors such as location, lifestyle and specific appliances impact your water heating requirements.
By gauging your usage accurately, you can better understand how much energy your solar hot water system needs to generate. This information is crucial in making an informed decision and optimising the efficiency of your investment.
Remember, the focus of this evaluation isn’t just about the current costs, but also the potential savings and benefits of switching to solar hot water.
Investing in a solar hot water heater can contribute significantly to energy conservation while reducing monthly utility bills. It’s a win-win situation for you and the environment!
To ensure the most effective adoption of solar technology, seek professional advice tailored to your unique situation. They will guide you through the selection, installation and operational process with competence and confidence.
Types of Solar Water Heaters Explained
If you’re thinking about installing a solar hot water system, you’ve got a few options to consider. The most popular in Australia is the Collector-Based or Heat Pump System. Let’s delve into more detail.
The Collector-Based System
This system absorbs sunrays via solar panels and uses that energy to heat water. The whole setup comprises of three elements: the solar panels, a storage tank, and a booster powered by electricity or gas.
Once the panel absorbs the heat, it transfers it to the water which then moves to the storage tank. The design of this tank ensures that the heated water rises to the top, while cold water remains at the bottom.
If for whatever reason, the stored water doesn’t reach the required temperature, don’t fret; the booster will automatically kick in. This ensures you always have access to hot water.
Different Types of Collector-Based Systems
You’ll come across two kinds of collector-based systems: Flat Plate Collectors and Evacuated Tube Collectors.
Flat Plate Collectors are relatively straightforward. They feature copper pipes and a large sheet of copper or aluminium. Together they absorb sunlight and heat your water before transferring it to the storage tank.
In contrast, Evacuated Tube Collectors are a tad more complex (and expensive). However, arguably, they’re better value for money because they’re more durable and efficient at absorbing solar energy.
The Heat Pump System
Then there’s the Heat Pump system which doesn’t require solar panels as it draws heat from surrounding air. Just like an AC unit, it extracts heat from outside your home and utilises it to warm your water supply. Don’t forget though, these systems are better suited to warmer climates.
Lastly, depending on your location, the Federal Government offers hefty subsidies to homeowners installing renewable energy systems. So, it’s worth checking out whether you qualify for any discounts to make your switch to solar power more affordable.
Active Versus Passive Solar Heating Systems
The type of solar heating system you choose can either be active or passive. Active systems utilise solar collectors and mechanical components to process the captured sunlight. On the other hand, passive systems use natural physics, without any moving parts.
Your choice between an active and passive system depends on several factors. These include your home’s design, your heating needs and the local climate. Regardless of the system you choose, most of them will need a backup heating scheme for times when solar heat is insufficient.
| Type | Description | Typical Uses |
|---|---|---|
| Active System | Uses solar collectors and mechanical components | Central heating, Water heating |
| Passive System | Relies on natural physics with no moving parts | Radiant floor heating, Direct air heating |
| Liquid-Based Active System | Uses water or antifreeze to absorb solar heat from collectors | Central heating |
| Ventilation Preheating | Potentially pre-heats air passing into a heat recovery ventilator or air-source heat pump | Pre-heating applications |
| Solar Air Heating Systems | Uses air as the working fluid for absorbing and transferring solar energy directly to rooms or via a heat recovery ventilator or air-source heat pump | Air heating for one or more rooms |
| NB: The specific type of solar heating system you choose depends on numerous factors, including your lifestyle, home design, climate and budget. | ||
This illustrates the key differences between active and passive solar heating systems. To make an informed decision, consider options that meet your needs and budget best.
The Environmental Impact of Solar Hot Water
Switching to solar hot water reduces power consumption drastically.
Just imagine, daily each heifer may consume around 18 kWh of power.
Solar Heaters: A Game Changer
If these heifers swapped their heaters to solar ones, they would lower this figure significantly.
Less power consumption lowers greenhouse gas emissions, thereby helping the environment.
Impacts beyond Energy Savings
The move to solar hot water heaters impacts more than just energy use.
It also reduces our dependence on non-renewable resources, thus preserving them for future generations.

This shift towards renewable energy goes to show how installing a Solar Hot Water system can be a strategic decision pumping up your property’s worth.
Understanding Solar Hot Water Cons
The Sunlight Advantage
Solar panels cover not just your hot water costs but your entire household’s energy consumption. The sun only needs to heat your water, eliminating the typical conversion process required by electric heaters. In fact, solar water heaters are more efficient than their electric counterparts.
Notably, solar hot water systems require less roof space than a full solar system, saving precious square footage.
Types of Solar Water Heaters
There are distinct types of solar water heaters: active and passive. Active direct systems heat the water directly in collectors before directing it to your taps and showerheads.
Active indirect systems utilise a heat transfer fluid to warm up the water supply through a closed-loop system. Conversely, passive solar water systems rely on natural convection currents where warmer water rises and colder water sinks.
Integral collector solar water heaters use metal flat plate collectors to heat small batches of water on your roof. However, they can weigh over 400 pounds, so ensuring that your roof can support this weight is paramount.
