Rooftop Solar Water Heating

The solar collectors capture the sun’s energy, heating the fluid inside them. This heated fluid then transfers the energy to water in the storage tank. When you use hot water, it’s drawn from the tank, and the system automatically replenishes it with cool water to be heated again.

• Energy savings: It can reduce your energy usage by up to 65%*, as it uses free sunlight.
• Environmentally friendly: Reduces carbon emissions, helping combat climate change.
• Long-term savings: A solar hot water system has a long lifespan, typically 15-20 years, providing long-term savings after the initial investment.

The size of the system depends on the number of people in your household, your water usage habits, and the climate in your area. A professional assessment can help determine the right size system for your needs.

Yes, many modern rooftop solar hot water systems are designed with frost protection to ensure efficient performance even in colder temperatures. In colder climates, a closed-loop system with antifreeze fluid may be used to prevent freezing.

The required roof space depends on the size of the system and the type of collectors used. Typically, a standard solar hot water system requires about 4-6 square meters of roof space, but this can vary.

Shade can reduce the efficiency of a solar hot water system. Ideally, the system should be installed on a roof that receives full sun for most of the day. If your roof is partially shaded, a professional installer can advise on the best placement to maximise efficiency.

Roof-top solar hot water systems can be installed on most types of roofs, including tile, metal, and flat roofs. The installation method may vary depending on the type of roof.

Regular maintenance ensures optimal performance. This includes:

• Checking the system for leaks or damage.
• Ensuring that the collectors are free from dirt and debris.
• Inspecting the tank for any issues, such as sediment buildup.

A professional servicing once a year is recommended.

Installation usually takes 1-2 days, depending on the complexity of the system and the roof type. After installation, it may take an additional day to ensure everything is working properly.

If your system requires repairs, a qualified technician can diagnose and fix the problem. In some cases, warranties may cover repairs for a certain period. It's always best to contact your installer or manufacturer for support.
