Condensate drain and soakaway. How's this for an idea?

[ToughButterCup]

I'm (second) fitting my MVHR next year. And wondering how to sort out the condensate drain .  Saw this  and thought that  a couple of 110 pipes inserted vertically like this would work wouldn't it ?  

 

Might this idea (suitably down-sized) be worth running past the BCO ?

 

 

Does anyone know how much condensate an MVHR system produces?

Tiny amount. I've never gotten round to plumbing in my condensate pipe, so it current fills a large plastic lunch box. Only really have condensate when it's cold outside. Normally in winter it's about ~100ml per day. Nothing in summer. I empty it a couple times a week.

Goddit, @Conor : some  20 > 10> mm chippings in a meter long 110 pipe, vertically inserted in the ground   with rat-proofing wire at the top.

Cheers.

I'm planning similar, straight out the wall, down through a waste pipe in to the ground. Our entire house is backfilled with 25mm stone, one giant soakaway. It's easier than trying to tie it in to the main sewer. No need.

It is only the condensate from indoor air, so not corrosive.

 

No more so than the moisture on windows.

 

Ours produces very little

can't you just tee it into something else and fit a dri-trap?

Well you can use a 110mm drain pipe with lime chips for a condensate drain for a gas boiler so don’t see why the same wouldn’t work for ASHP
