SOLAR THERMAL WATER HEATING

A solar thermal water heater utilises the sun’s energy to heat water. The process begins with solar collectors, which absorb sunlight and convert it into heat. This heat is then transferred to a heat transfer fluid, typically a water-antifreeze mix, which circulates through the system. This heated fluid travels to a heat exchanger located within a water storage tank, heating the water inside.

At Solares Energies, we offer advanced solar thermal water heaters designed to provide optimal efficiency and reliability. Our systems are equipped with cutting-edge technology, ensuring maximum solar heat absorption and seamless heat transfer to provide you with a consistent hot water supply.

A solar thermal water heating system is primarily composed of solar collectors, a heat transfer system, and a hot water storage tank. The solar collectors absorb solar energy and convert it into heat. The heat transfer system, usually consisting of pumps and piping, carries the heat from the collectors to the water. The hot water storage tank stores the heated water for use when needed.

Our systems at Solares Energies are designed for performance, durability, and ease of maintenance. We offer various collector designs and tank capacities to cater to different needs. All components are constructed with high-quality materials to ensure long-lasting operation.

The savings from using a solar thermal water heater depend on various factors such as the amount of hot water you use, the cost of your current water heating fuel, and the local climate. However, as a rough estimate, a solar water heating system can cover between 50% to 80% of your hot water needs on an annual basis, potentially saving a significant amount on your energy bills.

At Solares Energies, we provide a detailed analysis of potential savings as part of our consultation process. We take into account your specific circumstances to give you a realistic estimate of the financial benefits of switching to solar water heating.

There are primarily two types of solar thermal water heaters: Active systems and Passive systems. Active systems use pumps and controllers to circulate the heat transfer fluid, whereas Passive systems rely on natural convection. Each type has its advantages, with active systems generally offering higher performance, and passive systems being simpler and requiring less maintenance.

Solares Energies offers a range of both active and passive systems, with a variety of options within each category to suit different requirements. Our team can guide you on the most suitable type for your home, considering factors like your hot water needs, budget, and local climate.

While solar thermal water heaters are most effective in sunny conditions, they don’t necessarily require constant, direct sunlight to function. The systems can still capture and convert diffuse sunlight on cloudy or overcast days, albeit at a lower efficiency. The key is that the system needs to be correctly sized and positioned for your specific location and hot water needs.

Our experts at Solares Energies take into account the local solar radiation levels, as well as factors like roof orientation and shading when designing and installing your system. This ensures that you get the most out of your solar thermal water heater, even in less-than-ideal sunlight conditions.

Yes, a well-designed and properly installed solar thermal water heater can provide hot water throughout the year. However, the system’s performance will vary with the seasons, as it depends on the amount of available sunlight. In periods of lower solar radiation, like winter, the system may not be able to cover all your hot water needs.

At Solares Energies, we typically design systems for year-round operation, often integrating them with a backup heating source. This ensures a continuous supply of hot water, even in periods of low sunlight. The backup heater can be a conventional water heater or another renewable source, depending on your preference and circumstances.

Solar thermal water heaters rely on sunlight to generate heat, so their output decreases during periods of little or no sunlight. However, the systems include a hot water storage tank, which allows the hot water produced during the day to be used later, such as during the night or on cloudy days. For times when the solar system can’t meet all your hot water needs, a backup heating system is typically used.

At Solares Energies, we design our solar thermal water heating systems with ample storage capacity and efficient insulation to maximise the use of solar-heated water. We also provide various options for backup heating, ensuring a consistent hot water supply at all times

A well-maintained solar thermal water heating system can typically last for 20 to 25 years, possibly longer. The lifespan of the system depends on various factors, including the quality of the components, the local climate, and how well the system is maintained.

At Solares Energies, we use high-quality components in our systems, and our professional installation ensures optimal performance and longevity. We also provide clear maintenance guidelines and offer ongoing support to help our customers keep their systems running efficiently for many years.

Maintenance requirements for solar thermal water heaters are generally low. Basic maintenance includes periodic checks of the system components, such as the pumps, controllers, and heat exchangers, for any issues. The solar collectors should also be cleaned if they get dirty, though in many cases, rainfall is enough to keep them clean.

At Solares Energies, we provide comprehensive maintenance guidelines with our systems. We also offer professional maintenance services to take care of any technical aspects, ensuring your system continues to operate at peak efficiency.

Using a solar thermal water heater significantly reduces the number of traditional energy sources needed to heat water, thereby reducing carbon emissions.
