Polyplumb pipe

[kozak1968]

Just been looking on the back of a reel of polyplumb pipe and noticed it said you cannot use it on an oil fired sealed system. Whats the reason behind this?

 

[michael c]

could it be due to potential oil contamination on the pipe causing it to fail?

In case the control and high limit stats both fail. The boiler will soon heat the water beyond the melting point of the polyplumb, which will then melt and blast everyone in the vicinity with steam!

The boiler then melts because of a lack of water, falls through the earth's crust into hell where it releases the devil and all his imps.

We then have to listen to endless renditions of Tubular Bells.

So, in a nutshell, unless you like Tubular Bells, don't use polyplumb!

(Some of this was true by the way!)

Good effort sunshine

Would it not be the same with gas boiler and sealed system then?

Apparently not as it is rated for the job. Possibly something to do with combustion temperatures of different fuels ???


P.s oy croppie nowt wrong with tubular bells! You never seen exorcist ....

 

[Barry98]

How'd you finish that commercial off fell all done ?

First paragraph of post 2, and post 6.

Most plastic / pex is rated to a maximum temperature of 80c, the oil boiler is bigger so if it exceeds the 80c even if the high limit trips it still has a lot of heat to dissipate.

Gas boilers have small heat exchangers and more technology (PCB) so very unlikely to have much excess heat to dissipate after it stops working.

Either way the 1 metre (minimum) rule applies.
