Alde wet heating system

Melmodz, don't fotget to fully recharge your water system on your next trip out, so that water is running from all taps on the hot setting, before switching on the heating &/or water heater. It runs happily without filling

Not necessary with the Alde system.

 ....

To do it properly probably takes an hour. So with dealer rates ..... 

 .....

You're assuming the dealer will do it properly ..... 

It'd be as cheap if not cheaper to take it to Mercedes where they 'only' charge around £120/hr 

I make no assumptions. Mine was refilled at Alde at Lunars expense.

Would the Mercedes dealers have the special Aldi pump which would make the job quicker otherwise I suspect it would work out a lot more expensive.   I had ours changed by the local dealer but it still took me some time to get all the air out ( and find the bleed points) and I had to top up the system three times.

@ Greygit ..... I doubt Mercedes would have the pump, but my tongue was firmly in my cheek. Though if you look on YouTube the pump is anything but special. 

Our Alde heating seems to be working fine, although it does gurgle a bit at times.

Taking delivery of my new van in May has meant there has'nt been the need to use it other than the first couple of nights just to make sure it worked. A week ago we were at Wereham in Dorset and, despite some really good weather during the day, we had some pretty chilly nights and mornings. Not the depth of winter type chill but never the less it did what it said on the tin and heated the van. The juries out on whether the bathroom is as warm as our previous blown air system, but time will tell. It is very quiet, with just a gentle hum once up and running, after a little gurgle before the liquid gets up to full flow. I do think the boiler is more efficient at heating the water as it seems to get up to temperature quicker and stays hotter for longer. This could of course be because the Truma boiler has a larger capacity but we can both shower consecutively without using the boost.

Ours started to gurgle during the night last night.  I couldn't work out what it was to start with, but then it dawned.  However, it is much more efficient in keeping the van warm.

Ours developed a gurgle during the first week of use. I dopped the front of the van right down and bled at the rear radiator whilst topping up. Gurgle stopped.

We find that in the summer when temperatures are high our end washroom stays reasonably cool. In the winter however with the domestic style radiator it tends to be warmer than the rest of the caravan, Obviously I could adjust on radiator valves but we like it to be cosy if we are stripping off for a shower etc. If we are using the shower in cold weather I open the shower door in advance as the air behind the shower screen door stays cooler.

As we were in the Highlands from 7th April until last week in May it was very welcome as we had all sorts of weather .......... often in the same day!
