Vent Axia Sentinel Kinetic Plus B Diagnostic Screens


Recommended Posts

my observation would be that the warm moist air leaving the house is condensing within the extract ducting. The water trickles back towards to MVHR unit, wetting the filters and other components.

 

I am about to install mine in a un-insulated attic. this will increase the risk of the above happening for me too.

 

I intend to mitigate the risk by :

  • a using solid plastic, insulated ducting for Ingress/Egress vents.
  • Insulate pipes, connectors etc.
  • Fitting a in-line duct condensation trap on each Ingress/Egress ducts close to the unit
  • Where possible allow a gentle fall away from the unit for the exhaust duct/vent

draft plan below, welcome observations

I do have a question about a topic where i am looking for less theoretical answers and more 1st hand experience.

Is it ok to install the extract and supply vents on opposite sides of the roof as shown below.

I want to do this to assist summer bypass feature.

 

There are opinions of the units struggling to cope with pressure diff. on each side of the roof but , I am sceptical on this.....anyone got experience of this ?

thanks,
