Why Changing the Fluid in Your Alde Combi Boiler is Essential for Caravan Owners

If you own a caravan with an Alde combi boiler, you already know how vital this system is for keeping your caravan warm and your water hot. But did you know that the heating fluid inside your Alde system needs regular replacement? Ignoring this simple maintenance step can lead to expensive repairs and poor performance.

Why Does Alde Fluid Need Changing?

The fluid in your Alde heating system isn’t just water—it’s a special antifreeze solution that:

Prevents corrosion inside the boiler and pipework.
Maintains heat transfer efficiency for consistent warmth.
Protects against freezing during cold weather.

Over time, the protective properties of this fluid degrade. Old fluid can cause internal corrosion, sludge build-up, and even complete system failure. Regular fluid changes keep your heating system running smoothly and extend its lifespan.

3-Year vs 5-Year Alde Fluid

Alde systems use two types of antifreeze fluid:

Blue or Green Fluid – This is a 3-year fluid. It needs replacing every three years.
Pink or Lilac Fluid – This is a 5-year fluid. It lasts longer but still requires timely replacement.

If you’re unsure which fluid your system has, check the colour in the expansion tank. This quick visual check can save you a lot of trouble.

How to Check When It Was Last Changed

Look for:

A service sticker near the boiler.
Notes in your caravan service book.

If you can’t find any record, assume it’s overdue and have it replaced as a precaution. Better safe than sorry!
