HRV/ERV Ventilation ducting embedded in floor EPS
I have a proposed method to install flexible ventilation ducting embedded inside of EPS on the 1st floor (not ground floor, one above it, not sure what you call it in USA).
This is a brick and concrete house, so it’s not as easy as putting them through and between joists.
It would go like this:
– 3 inch diameter flexible plastic ducts would be laid on the reinforced concrete floor of the 1st floor (not sure if some sort of dampeners or something are used)
– holes would be left in the concrete for ducts to go to the ground floor rooms
– part of supply/exhaust pipes would go vertically through walls (supply on the bottom, exhaust higher on the wall), some would have grilles on the ceiling (kitchen..)
– between ducts, EPS would be laid
– over that, 3 inch screen with radiant heating would be laid
This is offered as an alternative to embedding pipes directly in the concrete floor, and suspended ceiling.
Suspended ceiling would add more to the house height, which is something we would want to avoid, and embedding in the concrete is problematic because the seller of the equipment is too far, so i would need to find someone local to do the installation, and there is nobody here who would know how to do the installation in the concrete. Apparently it’s a bit trickier than i had imagined.
Are there any possible negative sided against the proposed method of installing them on the floor of the 1st floor embedded in the EPS and covered by screed and radiant heat?
