Anyone use it above ground ?
 
We have used it for underground oil lines but always terminated it just at ground level .From memory you can take it to inlet side of fire valve as long as it's no nearer than 500mm from burner.

Not designed for above ground use I believe. Prone to UV damage.

says it’s uv safe but the website is contradictory says you can go from the tank to the fire valve without joints then further down not suitable for above ground use then on another page conifer green so doesn’t look to bad if on show :D

Hmmm, sounds legitimate lol. I personally prefer copper, you know where you stand with it.

exactly but for some reason Worcester won’t allow 10mm over 12m and this one is around 20m so have to do it in 15mm soft is way way to expensive so was looking for alternatives
 
Where are you getting that info from? That I didn't know of to be honest. When sizing a fuel line it should be done through your OFTEC books, you'd be surprised at what sizes some lines can run off. The problem is manufacturers won't warrant an installation if you don't follow there sometimes ridiculous criteria. Will there be a tiger loop?

Yep threw me aswell it’s only 24-32 so 10mm should be ok but Worcester state 12m max for 10mm

24-32 is nothing, 10mm should be fine, although overall length plays a part. Without doing the calculations I couldn't say what minimum size oftec would recommend but again you would void warranty if you don't comply unfortunately.
 
Exactly it’s one of them :D
 
I would say 20m maximum in reality around 17m probably

Quality pipe always a no no above ground. Only carry 10mm pvc coated copper. The copper is cheaper as well.

needs to be 15mm as it’s over 12m so best part of £230 for soft :(

Agree totally mate. We only ever used plastic coated copper. Even the smallest domestic installation probably has an oil tank close to 1000ltrs. If plastic pipe was installed wrong and failed on a gravity system then there will be a hefty clean up bill.

Quote up 12mm pipe? Even if you can't get plastic coated you could lag in some electrical conduit.

can’t get locally and tbh never seen 12mm

that was my thought 2 6m lengths of 20mm galv conduit just emailed qual to see there stance on it
 
I will I can’t see why in theory but there’s two possibilities

one mechanical or environmental damage

two fire risk
 

"Qual-Oil pipe is for below-ground use only. BS5410 was amended in March 2001 to include thermoplastic oil lines, which are approved by OFTEC, for below ground applications. For above ground applications metallic pipe must be used."

So, perhaps the answer to the paradox is that it's UV stable enough to store outside (for some unspecified length of time) but it can't be used above ground due to a prohibition in BS5410.
 
Still don’t know any half sunk tanks but I bet there’s one :D

looks like it’s 15mm and couplings

Yep and you can’t go from the tank to the fire valve without joints
