ventless clothes dryer

Haven't had to consider it yet. If we did, the dryer would have to be in place at final. We would require what the IRC requires, then note it for the record, and move on.

M1502.4.7 Exhaust duct required. Where space for a
clothes dryer is provided, an exhaust duct system shall be
installed. Where the clothes dryer is not installed at the
time of occupancy the exhaust duct shall be capped or
plugged in the space in which it originates and identified
and marked “future use.”

Exception: Where a listed condensing clothes dryer is
installed prior to occupancy of the structure.
 
The con is that the house could be sold to someone with a conventional dryer, these ventless dryers have been experimented with for the last 60 years.
 
Looks like condensing dryer equals a ventless driver.

Thanks for the code reference

Is it in the IMC?????
 
The evaporated water either goes down the drain, or collects in a tray that the user must empty after a cycle.
 
Florida has exceptions allowing the ductless, condensing dryers in the residential and mechanical codes
 
No, the IRC.

From the IMC;

504.1 Installation. Clothes dryers shall be exhausted in
accordance with the manufacturer’s instructions. Dryer
exhaust systems shall be independent of all other systems and
shall convey the moisture and any products of combustion to
the outside of the building.

Exception: This section shall not apply to listed and
labeled condensing (ductless) clothes dryers.

Interesting that it clarifies condensing with ductless.
