Different to my AWS - but I'll take Alde advice over his.Here we are with Alde’s advice. The level should be 1cm above the minimum mark when the system is cold.

it says about 1cm above min line when cool but I let the caravan engineer sort it for me 🙏
Well make sure he sets it at the correct level as recommended by ALDE as some on here have been given conflicting advice by their engineers.
When cold
Hi clive that not the only thing, i want the gas engineer to look at the radiators they are hot at the bottom but cold at the top so I think there trapped air so I think he have to bleed the system thanks for your help in this matter
Bleeding is quite easy just like you do at home. After bleeding don’t forget to check the fluid level and top up as required.
What is a simple task to some people, is not easy for others.
Identifying where all of them are located I found quite a challenge, adding to this access needed some disassembling of the furniture, admittedly that was doable.
It was finding the info of what was fitted and where seemed unavailable to us customers, probably so the trade gained any required rework.
I noted more recently the "trade" now simply blasts the fluid round* so it purged the bulk of the air with it, rather than the DIYer just having to use the gravity of the header and physically bleeding the bleeders.
* using a temporary pump system.
According to another earlier post, I thought that you posted that you had bled the radiator in the caravan or is this for at home?
I would have to agree no idea where to look 👍
Yes the one in the bathroom but i am on about the other 4 in the caravan don"t they need bleeding ?
The finned heat exchangers don't need bleeding themselves but there may be several bleed points in the pipework that circulates the caravan - they only need access after the fluid has been drained/changed/refilled - in almost all cases done by the technician doing the fluid change.
The only one I check is the radiator in the caravan bathroom, where the bleed screw is easily accessible on the side of the radiator.
You only need to bleed the radiator in the bathroom and as I mentioned, you may need to do it more than once. If the radiator is at the rear of the caravan, it is better if the front can be lowered for awhile while the heating is on and then do the bleeding again.
I thought recently there was a posting on another thread, about bleeding the Alde system, there was another bleed point at floor level, well hidden away, that can give rise to a fluid movement problem.
Some things are never straight forward.
On three different caravans with ALDE, we have only used the bleed point in the bathroom radiator to resolve any warming issues. Dropping the front of the caravan helped.
Maybe you and others have been ok, yet again dropping the front of the van would cause any air in the front radiators to get flushed back to the header tank/resovour
I am just surmising as I only know the basics of the system.
Might have a look when next there Thanks
