2021 303rls heat vent in bathroom behind toilet

[Dennis66]

Just wondering what the vent is for behind the toilet, when the heat is on I feel no warm air coming out. I took the cover off and its just a big opening with wires and water lines. Did they forget to hook up a heat duct there? I do see a small round vent in the cabinet lower in bath that I feel air there. My guess that's the heat source for the bathroom not sure what the other vent in the floor is unless it just allows air in that cavity under the floor.

Maybe a cold air return?

Hi Dennis,

The opening behind the toilet is the air return to the furnace from the upper level. There is a similar opening below the buffet for air return from the main level. The furnace does not have ducted air return. It draws from the basement space around it, which in turn draws from the two levels of the RV and over the wall from the pass through storage area. Actually . . . this works pretty well. In the summer (when you are not using the furnace) it makes some sense to block off the air returns from the living area since cool air from the AC will drop to the floor and disappear down these opening to the basement.

Great, makes since to block them off during summer months to help keep cold air in the cabin

A towel on the floor behind the toilet and a pool noodle under the front of the buffet, will work .
