Alde maintenance & Glycol Changes

To maintain the performance and corrosion protection in your sealed Alde central heating system it’s recommended the fluid should be changed every 2, or 5 years depending on the type of fluid currently in the system. The fluid is essentially an ethylene glycol antifreeze which is combined at a 50:50 ratio with clean, distilled water.

Fresh fluid prevents corrosion of the system, damage from freezing in cold conditions and improved heat conductivity making the system more efficient.

We only use the best quality Alde Premium G13 fluid and specialist equipment to clean and flush the system before refilling and disposing of the used fluid in a responsible and environmentally friendly manner.

If you have any questions or would like to book in a service or fluid change, please get in touch.
