Solar Thermal Panels

Solar Thermal System Service

Regular servicing of your solar thermal system is essential to keep it running efficiently and safely. Over time, the heat transfer fluid (glycol) in your system degrades due to exposure to high temperatures and oxygen. When this happens, the fluid becomes less effective at absorbing and transferring heat — and in some cases, it can even become corrosive, leading to damage within the system.

As part of a professional service, any degraded glycol is removed and new glycol is then pumped through to restore performance and protect your components. Replacing glycol helps maintain maximum efficiency, extends the life of your system, and ensures your hot water stays reliably heated by the sun.

Is a Solar Thermal System Worth It?

Yes, a solar thermal system is worth it — both financially and environmentally. By harnessing free energy from the sun, you can reduce your reliance on expensive fuels and cut your hot water bills by up to 60%. Over time, those savings add up.

Not only do solar thermal panels provide a reliable, renewable source of hot water, but they also help lower your carbon footprint — making them a smart investment for both your home and the planet. With a lifespan of over 20 years and with the correct maintenance, they offer long-term value, especially when installed by experienced, MCS-certified engineers like ours.

If you’re looking to future-proof your home, reduce your energy bills, and move towards greener living, solar thermal is a simple and proven solution.
