Condensation in the unit


Recommended Posts

So far there has been no condensation in my DIY unit.

 

However, I am in the design stage of DIY unit 1.1 which will be a much better insulated twin core model.

 

Am I right in thinking, should any condensation form, it will be in the extract (from home) chamber and that is where I should put a drain? Just in case.

Depends did you get a standard or enthalpy heat exchanger.

 

The enthalpy ones recycle the moisture back into the incoming air. So no condensation will accumulate.

I'm wondering, does any air get sucked in through the condensate drain?

 the water in the trap is enough to stop the "sucking".

They frequently discharge into the house waste plumbing, so should have a trap on it.

Does the condensate pipe need to be 40mm?, was thinking of using overflow pipe and chasing it into the wall in order to get it to a drain in our utility. Don't want to be boxing in. Would over flow pipe work?

Don't see why not, then drop it into a waterless trap in the utility.  The condensate pipe out of my unit is overflow sized; it's only taking a trickle at worst.
