Heat loss/gain from exposed metalwork.

Post by Wh05apk on Mon Jun 05, 2017 4:44 am

Noticed yesterday after parking our new kemerton with the rear facing east, the rear doors and the metal on the blinds was hot to touch, making the toilet compartment very hot, and I assume very cold in winter, whilst I prefer the clean look of the windows, having no opening windows in the back does make it very stuffy.

Our warwick duo from 2010 does not have a lot of insulation, I hoped that it had improved but this may not be the case. We are slowly adding more insulation as we get to each part of the van.  When it is hot we also use a usb powered fan that makes a huge difference when sleeping on a hot night.

That would suggest our Grade 3 insulation isn't as good as I'd hoped, both for winter and summer use.

I also bought a small 2 speed usb fan for the bedroom, but haven't had a chance to try it yet.

There is a usb socket and handy shelf perfectly placed in the bedroom opposite the bed, which I'm hoping will be enough for the summer.

Grade 3 insulation is less about the actual insulation but more about the power of the heater!

Insulation...... what's that? During carrying out a few 'repairs' to my van, I have noticed a disturbing lack/bare minimum of the stuff - it seems to be stuffed into cavities at random!

  Where I would not wish to criticise the build quality or lack of it I have to agree with you Stewart. The more one is forced to delve into the build of the van while doing repairs it does seem that there is a lack / bare minimum / inconsistent application of insulation . I also agree with the original poster as our similar van is cold in the rear area in winter and overly warm in summer . Using a minibus base vehicle gives you a nice look outside but there can be a lack of ventilation in the rear area with no opening windows. Our mod previously documented to the heating ducts has balanced the flow of heat to the rear in winter though.

Not wanting to get into an argument but our Warwick Duo hasn't got any exposed metal even the rear door Joint iis covered.
We have used it in very cold weather and found it the warmest van we had had (I put it down to be smaller internal space). I am comparing with a Compass Calypso, AS Executive, AS Windsor

I think keeping the van cool is more of a problem as you can always add more heat, the outside skin of our duo can get hot even when the air temperature is not.

We done the NC500 (or at least a large part of it) in January this year – cold enough for the external Whale socket pipework to freeze but we didn’t find the van excessively cold. This was probably more down to a 3 season double sleeping bag and the heating on rather than the insulation retaining the heat – the true test of the insulation will be in Spain next month.

On the subject of insulation, I found even more of the stuff in my van – soaking wet but insulation nonetheless.

The sliding sink in the WC developed a leak from the drain, causing the waste to emit from the wheel arch!

I managed to get my hand down behind the sink & wetwall, in amongst the wet insulation to recover the drain pipework.

I noted that there was absolutely no silicon/adhesive on any of the fittings – do A/S just push all the plumbing fittings together and hope for the best?

Anyway, all appropriate joints were siliconed and put back together so hopefully that’s another (and last) water leak fixed in my 8 month old van!

The only worry now is the ‘invisible’ water damage that’s been caused!!!!

That is shocking. I would take it, as soon as you can, to Mark at AS service centre and discuss options, go through your dealer of course. The sooner you get your issues on AS's radar, the better. 

Mark's your man.

Hi Stewart , glad you managed to get the pipework reassembled and sealed with some sealer . I agree its Inexcusable poor assembly practise. You would  think they should know better than to dry push fit pipework joints. Great meeting today and dont worry , a few days of warm sunny weather on holiday will soon dry out the insulation and wallboard as there is a good gap behind the sink to let the damp escape . Have a great time away!   Heres to a fault free trip!

Hi Masai,

Interesting that you mention Mark. I called A/S on Monday to be told Mark was with a customer. As requested I gave details of my problem to 'whoever answered the phone' and they told me Mark would call back.
An hour and a half later he returned my call - fair enough, he was dealing with an other customer and had probably been digging out piping drawings, build schedules, schematics, Bill of Materials, service testing, etc for my vehicle (I had originally given my A/S build number).
After a few minutes talking to him, explaining where the water was coming from he reckoned the pipes might run under the rear bench seat and it was maybe there that the leak was coming from.
I told him that area was dry and there weren't any pipes there. I asked him if he had technical drawings/information in front of him to assist - "No but I have the sales brochure for the Fairford. Maybe you should take it back to the dealer"
Incredible - £55,000 worth of an 8 month old motor home and that's the support you get.

I took the vehicle into the dealership on Monday and got it booked in for repair but as I sat & simmered yesterday over yet ANOTHER water leak, I went out and spent a few hours fixing it myself.

As for Mark and A/S, maybe I should send them the bill for my time and silicon used.

Stewart.   so_sad
