Alde UK approve ASC Mobile Caravan Services, this means I can carry out work on your Alde caravan or motorhome heating system without invalidating your warranty.

Alde heating systems in the UK come with a 50/50 mix of water and ethylene glycol antifreeze mix.

Normally the system is filled with antifreeze that has a two-year life, as such the system should be drained and refilled with the correct fluid mix biannually to carry on protecting your heating system. This can be carried out by myself BUT I will refill your heating system with 5-year antifreeze, this makes the drain down and refill more economical for you.

Long life antifreeze is available, and this will protect your Alde heating for up to 5 years and can be used when filling after a drain down

It is important not to mix the long life 5 year and 2-year antifreeze in your heating system, or Silicate and non-Silicate antifreeze.

ASC Mobile Caravan Services has the ALDE service pump, this will enable myself to refill your heating system or bleed it with ease and without the need of lengthy bleeding, as the pump forces the fluid round the system to expel the air.

Does your Alde heating system not get hot all the way round, or not heat up at all? The chances are your Alde system has an air lock, we can cure this with the Alde Service pump.

A newly filled Alde system will normally require topping up after it is used, as some small air bubbles can remain in the system, this is normal and should clear by itself

Drain Down and Refill (5 Year Long Life Antifreeze) £180.  including environmental disposal.
