Do you need unvented for under counter water heaters?

[Millsy 82]

As above really. I am on about the ariston europrisma type things. Also is there anything else instead of these as they tend to leak from what I've seen.

 

[Masood]

If they're over 15lt capacity then yes.

I like the hyco ones. You dont need your g3 but you still have to follow the g3 regs.

 

[Riley]

So sorry and I suspect I'm wrong but didn't G3 change to include under 15l too?? Or has it changed back?? Sorry I lose touch

 

[Ermintrude]

No Defo fine under 15l isn't one of the lads on here trying to test a tundish / drain

 

[SimonG]

Russ I think.

Even if you do need it I think I will be fine as I'm doing my unvented in a couple of weeks and will say I can't fit it in until afterwards.
