Heating upstairs

So here’s the shopping list of parts required - all for under £10 from Screwfix:

1 x 100mm ducting

2 x round to rectangular connector 90 degrees elbow bend:


Modify one of the elbow bends by cutting a section out of it, and file the edges for a nice finish, per following photos. Standard elbow (no cutting) on the left of each photo, modified elbow (after cutting) on right hand side of each photo.

Hopefully helpful

Perfect. The forum at its best. Thanks
 
@Californication69 & @Camperfamily thanks for the quick and useful responses. Have ordered similair parts, since we don't have 'screwfix' over here, but I'm sure it'll turn out just fine. So thanks! I am considering spray painting the duct ends black to make the whole thing look a bit less DIY. Will post a photo in this thread as soon as the work is done.

Black would look good and you can get black pipe too.F619F6A8-0CCD-4AF0-A354-2CD3A62F5D0D.png
 
It would be great is...
1) someone, or the shop would start selling complete kits, ready to assemble and fit, or
2) we could get a shopping list of part numbers and supplier details, so we could buy the bits ourselves. This was done for the bike rack security and similar projects.

Here's hoping!
I don't have the parts number but in this post you could see clearly all you need : https://vwcaliforniaclub.com/threads/internal-heater-altering-airflow-direction.35909/post-438919
 
Thank you @Camperfamily :cheers
It was you who’s post I saw and created the same.
I did try to go big, 8 inch, but sent it all back and got 6 inch as it fits the night heater slot perfectly.
And yes @ThomasHJ you have to cut a slot out of the 6inch round to rectangular end.
just the bit that stops it going into the vents.
Mine works an absolute treat !

Maybe think of having the outlet lower. Heat rise, so you may be missing out on some of the heat.

Tried it @Elly Swanson blows hot / warm on my head and I like a cold head and warm feet ! :D

Might extend it to a 2 foot wide plastic nozzle and have it by my feet blowing up in the duvet :Grin

Are you doing this project as well @GrumpyGranddad? So far I have received the ducting and the clamps and I have spray painted the ducting ends black (couldnt get black ones). As soon as everything is dried I will start to put it together and take some photos

Yes I am Thomas :)
Like you i have the black ducting and am spraying the end pieces black (spraying with a plastic primer first). Ducting end is a nice push fit into the grill at the bottom (although i might add rubber edging. Not sure how i’m going to attach at the top yet - exploring options.

Something like this at the bottom to make it a slightly tighter fit. Maybe?

This was my parts list. Prices include postage where applicable. Total £18.97, plus a couple of zip ties and an angle bracket from the shed.

Round suction cup (£2.20): https://www.ebay.co.uk/itm/200790859945
Top grille (£2.99): https://www.ebay.co.uk/itm/153989061894
Black ducting (£10.79): https://www.amazon.co.uk/dp/B07NWV6TRZ/?tag=eliteelect-21
Bottom angle (£2.99): https://www.screwfix.com/p/manrose-...ector-elbow-90-bend-adaptor-white-100mm/96549

The top grille allows you to direct the angle of the flow, but means it still packs up nice and small when not in use:

Nice. How are you attaching the suction cup?
 
The cup goes on the painted bodywork above the driver's door. This puts the grille at the same height as the upstairs bed, but the grille then directs airflow out at 45 degrees backwards (as though it's then eventually hitting the roof at 90 degrees, if that makes sense). It's the 45mm cup with metal hook.

I should probably point out that this has tested well, but hasn't been used in anger yet.

Yes, good idea. I removed the B-pillar vent to see how the duct end fits on the inside. But to be honest, as it is now, it doesnt stay in place in the vent very well. The added paint layers migth help, but perhaps your idea of adding a rubber profile is a smart one.

Must say that the spray paint makes for a nice result. The duct ends now have a mat black finish and look nice.

The use of blac tie-wraps that @haydnw2 suggests is nice because they are black. For now I am using hose clamps though, allowing me to remove the duct ends easily. Perhaps when the thing's finished I will finalize it with black tie-wraps.
 
I like how my suggested 15 minute and under £10 hack is being developed by others into a refined bit of kit, with spraying the ends and sourcing black ducting. One of the reasons I love this forum.

I fear I may need to upgrade to v2 once I see some of these refinements.

You can get black re-useable tie-wraps. Best of both worlds!

Got it. Yes, I can’t imagine how you’d get to sleep if your head was too warm. We sleep with heads at the short end and don’t like our heads the other way round at all.
 
I'm wondering. It seems quite some people are doing or have done this diy. Has anyone taken any measurements? As in, did anyone check what temperature difference the contraption actually makes in the upstairs bed?

I’ve not measured it, but I can only speak for my experience which is that it makes a lot of difference.

A key benefit is that it achieves a much greater balance between upstairs and downstairs temps, even when using a topper (Pucer in my case), as it allows heat to be pumped into both upstairs and downstairs ‘zones’.

If you are only using one of the two beds, then the (typically large) difference in temps between the two zones doesn’t particularly matter - use the heater to heat whichever zone you need to the desired temp and don’t worry about the other. Although that is a little wasteful if you are sleeping upstairs and are overheating downstairs to make up for heat loss upstairs

I did find some black jubilee clips but, whilst not overly expensive per se, they did push the project cost up disproportionately! £6.88 for a pair. https://www.ebay.co.uk/itm/143540474102 Also, largest size seems to be 100mm so fitting would be touch-and-go I suspect. At that size you seem to be into engine hose clip territory, and everything gets expensive very quickly.
