We have one installed on our Helia Evo but have only used the dryer function once. Ours is not vented with ducting, it just expels hot air into the shower cubicle area. Obviously keep the door to the laundry cupboard open and stay on board when in use!
We have a splendide washer dryer combo. It is installed aft of the head on the starboard side (older Helia layout). Dryer vents into the deck locker. We open the locker when we use the dryer. Need to install a lint catcher to kept the lint down in the locker
