All in one, 120v, ventless, heatpump washer and dryer

blamus20 | Posted in Building Code Questions on

I think this is a code question – the new LG washer dryer combo is 120v and ventless. GE also has one. So if I plan to use one in a new construction home, does code require vent piping to be installed for the dryer and 240V receptacle at the laundry location?

    blaumus20,

    The IRC excludes condensing dryers from venting requirements.

    See: M15.2.4.8

    It's basically a washing machine. Same hookups. I put one in at work. One might consider provisions for a old school dryer unless it is onerous. Tough sledding with a family with a condensing washer/dryer

      These are heat pump machines, they perform somewhat better than classical condensing machines, but are still slower vs conventional gas or electric vented machines.

    I really wish someone would make an all-in one vented unit. All of the all-in ones are ventless with a lot of complaints about long run times. I think one of them even required you to manually switch modes from washing to drying in the middle of the cycle. For space saving and convenience, I'd like an all-in-one but I'd want it to have a 240V traditional dryer cycle.
