Solar Thermal

Fully Certified Renewable Installer

Providing confidence in home-grown energy

Solar thermal systems use specially coated reinforced glass pipes within a solar collector, typically installed on the roof, to absorb solar radiation and heat water. These collectors contain an eco-friendly heat transfer fluid, which circulates through the system, transferring the captured heat to your hot water tank. The system is automated, with a solar thermal controller that activates the pump when the temperature in the collectors rises above that in the storage tank, ensuring efficient and consistent hot water production.

Even in the often cloudy UK climate, solar thermal systems can effectively heat water, making them a viable and sustainable solution. While bright sunlight is ideal, solar collectors work efficiently in diffuse light, providing reliable hot water even on cloudy days. During winter, a boiler or immersion heater can serve as a backup, ensuring your property has ample hot water year-round.

  • Residential Applications: Perfect for households looking to reduce energy bills, particularly in homes with high hot water demands.
  • Commercial Applications: Ideal for facilities with large-scale hot water needs, such as hotels, care homes, and industrial settings where traditional heating systems are expensive to operate.

Greenfields can design a system that fits your needs, whether it’s a single-panel system for a small home or a megawatt system for large-scale hot water production. Contact us to learn more about how we can tailor a solution for you.

How does solar thermal technology work?

Solar thermal systems use collectors to absorb solar energy and heat a fluid that transfers this heat to your water tank, providing hot water for your home or business.

Is solar thermal effective in the UK climate?

Yes, solar thermal systems work well even in cloudy conditions, as they require light, not direct sunlight, to generate heat.

Can a solar thermal system provide all of my hot water?

During the summer, a solar thermal system can meet up to 100% of your hot water needs. Over the course of a year, it can typically provide 50-60% of your hot water, with backup systems covering the remainder during winter.

What size system do I need?

The size of your system will depend on your hot water usage, the climate, and the size of your property. Greenfields can help you determine the best system size for your needs.
