Solar Thermal Maintenance

Solar thermal maintenance  is essential to ensure you get the most out of your technology. Solar thermal systems must be serviced annually to avoid downtime and system failures. The glycol fluid should be topped annually to maintain the freezing point of the heat transfer fluid (typically minus 15 to minus 25 degrees). The pump station must also be checked regularly to protect its warranty.

Solar thermal maintenance looks at many elements that need to be looked at including the collector, hot water tank, the heat exchanger and the pump.

Annual servicing will extend the lifespan of the system, as well as preventing future repairs and breakdowns, ensuring it works reliably 100% of the time. Hybrid Energy Group are working throughout Cavan, Monaghan, Meath and Dublin.
