Frequently Asked Questions

• Why is a special heat-transfer/antifreeze mixture used in solar systems instead of ordinary water? Solar collectors are exposed to outdoor temperatures including frost, where ordinary water would freeze and could damage the piping and the collector itself. The special mixture also withstands the high temperatures that can occur in the collector during strong sunshine without heat being drawn off.
• How often does the mixture in the system need to be checked/replaced? Regular checks of the concentration and condition of the mixture are recommended (usually once every few years, the exact interval is given by the manufacturer), as its properties can degrade over time due to high temperatures and ageing.
• Must the mixture be replaced/topped up by a professional? Yes, filling and venting the solar circuit requires professional knowledge and suitable equipment (a filling pump) to prevent air bubbles in the system.
