5.5 Alde Heating System and Coolant Replacement Service

Alde Heating System and Coolant Replacement Service

The Alde “wet” heating system, commonly installed in caravans and motorhomes, offers a high level of comfort by operating similarly to a household central heating system. Instead of blown air, it circulates a specific heating fluid throughout the system, which heats your space and provides hot water. Many owners prefer this system due to its quiet operation, consistent warmth, and energy efficiency.

Benefits of the Alde Heating Fluid

The Alde heating fluid, available in Blue and Pink variants, serves multiple purposes:

• Freeze Protection: The fluid prevents the heating system from freezing, so there’s no need to drain and refill it. However, it's important to drain the fresh water system to prevent damage from frozen water.
• Corrosion Resistance: The fluid contains inhibitors that protect the boiler and pipework, keeping the system running smoothly.
• Enhanced Heat Transfer: The heating fluid is more efficient at conducting heat than water, making the system both effective and cost-efficient.

Frequently Asked Questions

Q: How can I check my system levels?
A: Check the expansion tank in your caravan or motorhome. If the fluid level or color isn't visible, unscrew the cap for a closer inspection. The fluid should be about 1 cm above the minimum mark when cold.

Q: Blue or Pink? How often should the coolant be changed?
A: If your heating fluid is BLUE or GREEN, change it every two years. PINK heating fluid lasts five years and is recommended for long-term use.

Q: What happens if I don’t change the fluid on time?
A: As heating fluid ages, it loses its effectiveness, causing corrosion, pump inefficiency, and, in extreme cases, boiler or heating element failure. For long-term savings, Alde recommends switching to PINK fluid if your system still uses the original BLUE fluid.

Q: How is Alde heating fluid changed?
A: Fluid change requires a special Alde setup of pumps and valves. New fluid is pumped in, pushing out the old fluid while circulating through the pipework to eliminate air pockets. The system is then topped up and checked for consistent heat output.

Q: How much does a fluid change cost?
A: We offer Alde fluid changes from £299, using Alde-approved Blue and Pink heating fluid for optimal system protection.

Q: How can I tell which fluid I have?
A: Locate the header tank inside your vehicle. If your fluid is Pink, you may find a sticker or note indicating the next replacement date. Systems filled with Pink fluid should only be topped up with Pink fluid, while systems with Blue fluid can be topped up with either Blue or Pink fluid.
