plastic one meter from boiler

[dextur]

I Know plastic need to be a meter from a boiler. But what about hot water cylinders vented or unvented? Is it still a meter?

 

[muggles]

Copper is always the recommended pipe material whatever the situation, but for unvented consult the manufacturer for their guidance

 

[SandyLyon]

As above always read the manufacturers instructions

Some may say a metre others more

Its not as simple as that , some pipe manufacturers state one distance and some boiler manufacturers state another, I would always go on your own thoughts about 1M but it actually depends on lots of other things like pump overrun OH stat, Hi Limit stat present in said appliance, I got involved with this with a large energy supplier who refused to take systems on their maintenance contract when the PE pipe was connected to the boiler isolation valves, when you start to look into it in depth it is a real minefield, for peace of mind 1M will see you alright

 

[dextur]

what about unvented hot water cylinders do these need a meter of copper too?

Presume you could connect straight on in plastic if you wanted?
