ALDE Fluid Change


If you’re fortunate enough to have the ALDE Hydronic Central Heating System fitted in your caravan or motorhome, you will appreciate the necessity for keeping it well maintained.

The heat transfer fluid must be replaced before its protection expires, and this timescale differs depending on which type is used.

We pump the old fluid out and refill with 5-year Glycol anti-freeze fluid, to ALDE’s recommended specification. This Glycol is able to cope with temperatures to -37°C. It acts as an antifreeze and offers a protective layer against corrosion, as well lubricating the circulation pumps and helps to prevent bacterial growth in the heating system.

Our ALDE service charge includes disposal of waste anti-freeze. Invicta Caravan Services is a registered waste carrier.
