After the first 2 years, Alde recommend replacing the antifreeze in the system with a 5-year G12evo spec product.Please note that the Alde G13 antifreeze is no longer available and has now been replaced by the G12evo. Please see the FAQs for more information.Alde Premium G12evo (formerly G13) is compatible with the blue 2-year antifreeze* used by most UK caravan and motorhome manufacturers, and can be used for topping up.
Alde Premium G12evo is ready to use, pre-mixed with deionised water, and does not require further dilution and is ideal for topping up Alde central heating systems. Alde G12 evo premium antifreeze ready mixed premium quality glycol for Alde heating systems with long-life 5 year corrosion protection.
The Alde G12evo premium antifreeze, 1 litre, stands out as a superior solution designed specifically for caravan and motorhome heating systems. Recognising the central role of the boiler in your heating setup, the Alde Premium G12evo Antifreeze is likened to the vital fluid that ensures the system's operational integrity. This high-quality antifreeze not only offers exceptional protection against freezing conditions, capable of withstanding temperatures as low as -37 °C, but also enhances the overall longevity and efficiency of your heating system. The product's formulation includes essential components that prevent corrosion, lubricate the circulation pumps, and inhibit bacterial growth, ensuring that your system remains in optimal condition.
In addition to its antifreeze capabilities, the Alde G12evo premium antifreeze offers a multitude of benefits that extend beyond simple freeze protection. Its unique composition is specifically tailored to complement Alde heating systems, providing a protective layer that safeguards against internal corrosion. This protective film is crucial for maintaining the system's internal components in pristine condition, thereby facilitating smooth circulation and ensuring that your heating system delivers consistent, balanced warmth. The lubricating properties of the glycol further enhance this effect, aiding in the seamless operation of circulation pumps and other moving parts within the system, which is vital for the longevity and efficiency of your heating setup.
The Alde G12evo premium antifreeze is not only a testament to Alde's commitment to quality but also to the convenience it offers to users. Unlike standard glycol solutions that require biennial replacement, the Alde Premium Glycol G12evo Antifreeze's advanced formulation ensures that it only needs to be changed every five years, providing sustained protection and peace of mind. This extended service interval underscores the product's durability and cost-effectiveness, making it an ideal choice for caravan and motorhome owners seeking a reliable, long-term solution for their heating system maintenance.

SAFETY NOTICE:
All products and parts must be installed by engineers who hold a valid certificate of competence. The installation must comply with the manufacturers instructions and local regulations. We cannot be held responsible if these instructions are not followed.
Please note we are a camping, caravan and motorhome company and NO gas product that we sell is suitable for mains (domestic) gas supply.
No - Only deionised water should be used. Tap water should be avoided whenever possible as it can cause corrosion.
After its recommended lifespan, the qualities of the fluid will degrade.
The qualities of the Alde G12evo antifreeze are;
1. Antifreeze - at a 50/50 ratio it can perform down to -37C;
2. Coolant - The Alde Heating system is a balanced controlled system, the coolant is vital in removing the heat away from surfaces.
3. Corrosion Protection - Very important to keep your system running at it's optimal performance.
4. Bacterial Protection -This prevents microbe activity building up in your system. As the fluid degrades down to a 27% ratio then the antifreeze & coolant loses its quality which will result in cooling issues. At 20% ratio there will be bacterial growth where micro-organisms can build up in your system resulting in a fishy/rubbery smell in your system. At 10% ratio there is 100% chance that there will be bacterial growth!
This is a result of too low concentration of the antifreeze fluid. If the levels get down to 20% concentration then the protection is very low and micro-organisms will build up in the system causing this smell. The only option to rectify this is a total flush out of the system. Alde do provide this service at their Wellingborough Workshop or your contact your local dealer.
Alde G12evo (G13 no longer available) Antifreeze is a very high quality antifreeze mixed in the optimum ratio for your Alde Heating system. If you decide on a cheaper option then you will likely not receive the optimal performance from your system.
Please note the the G12 antifreeze (not offered by Alde) is not compatible with the Alde systems.
The qualities of the Alde G12evo antifreeze are;
1. Antifreeze - at a 50/50 ratio it can perform down to -37C;
2. Coolant - The Alde Heating system is a balanced controlled system, the coolant is vital in removing the heat away from surfaces.
3. Corrosion Protection - Very important to keep your system running at it's optimal performance.
4. Bacterial Protection - This prevents microbe activity building up in your system. Weak antifreeze mixtures of less than 20% will have microbe growth resulting in bad smells.
The colour of Antifreeze is not important as you can have the same antifreeze but be two different colours. Thus, in theory the colour is not relevant. However, we would never recommend mixing two different Antifreezes together. What would likely happen is a chemical reaction between the antifreezes which would nullify the quality of them. This would then potentially damage your Alde system. Alde G12++/G12evo or Alde G13 can be added to any system and will not react with the antifreeze currently in your system.
The Alde G12++ is exactly the same as the Alde G13 but the method of creating the G13 liquid is more environmentally friendly. In 2024 an ingredient of the G13 was banned in Germany. Since then, manfacturing of G13 has ceased for the main manufacturers. Alde G12evo is available in smaller quantities (1ltr & 4ltr) and the G12++ is available only in larger quantities. There is really no other difference according to Alde. They are compatible and can be mixed together according to Alde.
This is 50% silicated (OAT) Organic Acid Technology antifreeze and 50% deionised water. This is the optimum mix for your Alde System. Please note that as of the end of 2024, this was no longer available and has been replaced by the G12evo / G12++.
This is likely that you have a too strong ratio of the antifreeze or too weak. We recommend replacing the antifreeze well within its lifespan with Alde G13/G12++/G12evo antifreeze. If you leave it too long then the antifreeze will degrade resulting in overheating issues. Also, if you have mixed the antifreeze with water yourself and the ratio is more than 65% then this again will result in overheating issues.
If you put more than required (more than the minimum level) then the excess fluid (Alde Antifreeze) will drain from the expansion tank to the outside of the vehicle.
On a new van, the antifreeze used has a 2 year lifespan. We recommend changing it with Alde G13/G12++/G12evo Antifreeze after that point which has a 5 year lifespan.
There is a total of about 14 litres in your Alde Heating system.
On a new van after a month of use there is a good chance it will need topping up as air leaves the system. Ensure then system is showing that the Alde antifreeze level is at the minimum level when cold. To check for air, run the pump continuously for an hour and then bleed all the radiators.
You can tip more Alde antifreeze into your system via the expansion tank, normally located in a wardrobe.
