How To Maximise The Efficiency of Your Solar Hot Water System: A Handy Guide

Harnessing the power of the sun for your hot water needs is an eco-friendly and cost-effective solution, but like any other appliance, the efficiency of a Solar Hot Water System (SHWS) is vital to its performance. A well-maintained and efficiently running system ensures you get the most out of your investment. Here, we share expert tips on how you can maximize the efficiency of your solar hot water system.

Correct Installation

First and foremost, the installation of your SHWS must be done correctly by a certified solar hot water plumber. The system’s solar collectors should be correctly oriented towards the sun, typically north-facing in Australia, and angled optimally to catch the maximum sunlight throughout the year.

Regular Maintenance

A well-maintained system is a high-performing system. SHWS should be serviced every 3 to 5 years by a professional to ensure optimal operation. This service includes checking and cleaning solar collectors, inspecting pipework for leaks or damage, and checking the system’s controls and pump for proper operation.

Timely Repairs

If you notice any signs of malfunction, such as lukewarm water, strange noises, or water leaks, get the system repaired immediately by a professional. Minor issues, when ignored, can escalate into major problems, decreasing the system’s efficiency and potentially leading to costly repairs.

Insulate Your Hot Water Pipes

Insulating hot water pipes can prevent heat loss as the water travels from the tank to your taps. According to the US Department of Energy, insulating pipes can increase water temperature by 2 to 4 degrees Fahrenheit, reducing heat loss and allowing you to lower your water heater temperature setting.

Use Hot Water Efficiently

How and when you use hot water can also impact the efficiency of your SHWS. Using appliances that require hot water, like dishwashers or washing machines, during daylight hours ensures you are using water heated by the sun, saving the booster for when it’s needed most.

Adjust the Temperature

During summer months when solar radiation is high, you might not need your system’s booster. Adjusting the temperature setting or turning off the booster during these times can help save energy and improve system efficiency.

Replace the Anode

The anode rod in your hot water tank helps prevent corrosion, extending the life of your tank. Regularly replacing this rod (approximately every 5 years) ensures your tank remains in good working condition and operates efficiently.

Install a Solar Controller

A solar controller optimizes the use of solar energy by only activating the circulation pump when there is enough sunlight to heat the water. This intelligent use of solar energy can greatly enhance the system’s efficiency.

Peter Hill, a respected Sydney-based hot water plumber, remarks, “Solar hot water systems are more than just an eco-friendly alternative. With proper care and use, they can provide substantial energy and cost savings. Maximizing the efficiency of your system is a smart way to maximize these savings.”

By taking these measures, you can ensure that your solar hot water system runs efficiently and delivers maximum savings. Remember, when it comes to maintenance and repairs, always trust a certified professional to do the job right. Maximize your solar savings today with an efficient and well-maintained solar hot water system.
