We offer a full service of your Solar Thermal heating circuit including chemical flushes and fault diagnostics. Poor circulation within a solar thermal circuit is one of the main issues that can arise with a lack of servicing. Glycol can overheat and cook within your system causing blockages and acidity levels to rise which can cause major problems with pipework, collectors and pump components and seals. Glycol within your system also degrades over time leaving your pipework and collector prone to freezing. An annual service of your solar thermal heating will ensure its operating at it's maximum efficiency as well as preventing any costly issues that can arise down the line.
