3 FAQs on the Antifreeze for Alde Heating Systems, 4 litre


I have an Alde 3020 fitted in my new motorhome. Do you have any tips?
by James Atkins


Here is some important information that you should know:

- Do not run the system dry, empty of antifreeze solution. The boiler will be damaged beyond repair.
- Do not use greywater or desalinated water in the fresh water system. Only use potable drinking water to avoid corrosion of the stainless steel.
- Do not use a sterilising or winterising chemical in the fresh water system unless it is suitable for use with stainless steel. Puriclean by Clean Tabs is recommended.
- Do not rely on the central heating to prevent the fresh water from freezing, even if living in the vehicle. Always drain down for winter unless the vehicle is explicitly stated to be self-winterising.
- Do not mix incompatible antifreeze. Either top up with the same spec antifreeze, or use VAG G12++ or G13 Spec.
- Do not use hard water to mix the antifreeze solution. Deionised water is recommended.
- Do not dispose of antifreeze in any way except in accordance with PPG19, it is against the law.
- Do not open the bleed screws whilst the circulation pump is active. Air may be sucked into the system.
- Do not obstruct the air vents in the boiler compartment. The thermal fuse might cut out.
- Do not use gas heating whilst driving. Even with a crash sensor regulator fitted. Gas heating must be off when pulling into a fuel station.
- Do not rely on gas heating at high altitude. LPG combustion and performance is impeded above 1500 metres by the Laws of Nature. 3020 boilers in 2017 leisure vehicles have a High Altitude Mode on the control panel.


I am thinking of installing an Alde 3020 boiler. What general maintenance and consumables are there?
by Harry Kendrick


The vendor should provide a maintenance schedule, though the following can be assumed:
The ethylene glycol antifreeze is a consumable and will need replacing before its protection expires. Most UK OEMs use silicate-containing antifreeze with 2-year protection from new.

Seasonally inspect the boiler's flue hoses. Check that the hoses are still secured and undamaged, and that they're clear and unobstructed.
When in constant use, completely drain and refill the fresh water system once a month.

Safety and emissions tests should be carried out in accordance with local codes and regulations.


What antifreeze should I use with Alde boilers?
by Bradley Gisson


Most of the caravan/motorhome manufacturers in the UK supply their vehicles filled with 2 year antifreeze. This is normally blue; however please check with your manufacturer.

If topping up your system, or replacing the fluid in your system, we advise the use of Alde G13 spec antifreeze as this is backwardly compatible with any pre-existing antifreeze in your system. The main benefit is that it has a 5 year corrosion/frost protection, saving you time and money in the future.

The fluid in your system should be a mix of 50% antifreeze and 50% deionised water. This will provide optimum protection down to -37°C. (The strength of your fluid can be tested with a refractometer or hydrometer).
