How Do Solar Hot Water Systems Work?
Solar hot water systems harness the sun’s power to provide the water heating necessary for your home. They consist of two major components:
Solar collectors and a storage tank. Solar collectors mounted on the roof of your home capture sunlight and use it to heat either water or a special heat-transfer fluid. That hot fluid then transfers its heat to the water in the storage tank. Variations on the solar hot water system exist and work quite well; however, these systems function best in direct sunlight (meaning they do well in places like the desert Southwest).
They don’t do as good in lots of cloudy days or when big trees block the sun. But even if the solar units can’t work at full power, the backup water heater will make sure you still have enough hot water for your morning shower. And to up the eco-friendliness of the system, the backup using a gas heater works with less energy than traditional water heating methods.
When it’s dark out or the sky is grey, a backup booster (electric or gas) guarantees you always have hot water. Should the sun not be out enough to heat the water, the booster automatically activates to maintain your water hot and ready to use

Cost of Solar Hot Water Systems in Perth
In Perth, buying a solar hot water setup can run you from $3,500 to $7,000. The cost swings with a few factors: kind of system (flat plate or evacuated tube), brand (like Solahart or Rheem), and size of the tank (big tanks are pricier). You might save $500–$1,000 on it with help from small government grants, which depend on your setup and location.
Old school electric or gas systems cost less upfront. You’d spend $500–$1,900 for electric, and $800–$1,400 for gas to start. Yet solar can keep money in your pocket as years pass. It can slash your hot water costs by 50–80%, saving $300–$500 each year in Perth’s sunny weather. Consequently, in five to ten years, it may cover its price. Moreover, solar is environmentally friendly and so lowers your carbon footprint. Therefore, even at the more expensive starting price, the benefits of the savings and their assistance to the environment make it a good decision.
How Long Do Solar Hot Water Systems Last?
Solar hot water systems can last 10–15 years. With good care, they can work for up to 20 years! In Western Australia’s weather, taking care of them often is key to keeping them going well. The hot sun and salty air can harm them faster if you don’t look after them.
You might need to get a new system if you see rust, leaks, or if it’s not making water hot like before. To help your system last longer, have it looked at by someone who knows how often and fix any small issues soon. Doing this will help your solar hot water system give you hot water for a long time!
Best Solar Hot Water Systems in Perth: Reviews & Recommendations
In sunny Perth, Western Australia, solar hot water systems present a great chance to lower energy consumption and save costs. Rinnai, Apricus, Rheem, and Solahart are among the best-known manufacturers listed briefly here. Choosing these brands involved considerations on price, warranty, customer reviews, and efficiency, among other things.
- Rinnai: High effectiveness Rinnai systems use evacuated tubes or flat plates to convert solar energy into useful heat for your home. They are among the most sunlight-conversion-efficient systems available and save anywhere from 65-95% on your home water-heating bills. They range from 4,000-7,000 dollars, with a 7-year warranty. And their low running costs make them the “up and coming” stars for solar hot water in Perth.
- Rheem: Hiline and Loline systems are efficient,
TANKS: 270L–444L
PRICES: $4,000–$6,500
WARRANTY: 5–7 years. Leaks were reported by some users after about 10 years, but the service is highly praised.
- Solahart: A WA brand that people trust, Solahart’s 302L system is very good for the average-sized medium household. Installed costs run between $4,500 and $7,000, and it comes with a 5-year warranty. Users sing the system’s praises for durability and mostly quiet operation, but note that the system is occasionally a little too eager to narrate its many functions. Survival of the system past 5 years seems a certainty. What of the next 5 years? I think the unit is good for at least that and probably well past it.
- Apricus: The evacuated tubes Apicus uses make for a very efficient product, with up to 95% efficiency being the norm. They are also ideally suited to the climate in Perth, where the system works best; the price is in the range of $4,000 to $6,500; and the warranty is for 7 years. Customers seem to like the design; they say it is frost-proof, and they also seem to like the readily available support from the locals.
Base your decision on family size and water use. A 300L tank fits 3–4 people well, and a 400L+ tank suits larger families. Look up your local rebates; they might take a chunk off the cost.
