Hot steamy showers - and dripping condensation

[Rich Thomas]

I rented to a woman with two children. It turned out the her "children" are big strapping 17 and 18-yearolds.

The three of them like to take hot steamy showers. The rental is 2-bedroom, one bath duplex with electric baseboard heating.

Interior humidity level is always very high and condensation is problem. It's a cooler/cold climate (western Washington state).

I upgraded the bath fan to 100 cfm (double previous fan's cfm) and added a timer switch so that they could leave the fan on to go to work/school.

Even so, it is still far to humid in the house.

Is there a solution to this problem of excessive interior moisture?

If the humidity is limited to, or centred on, the bathroom, I'd upgrade your switch to one with a humidistat and timer both (we do this with all our student rentals). A timer switch only works if it is engaged when the lights are turned on ... otherwise, they won't turn it on and set it.

We also put a 120cfm or 150cfm 4" or 6" low sone fan in the washrooms.

If the humidity issue is throughout the unit, then you might want to talk to an HVAC person about an air exchanger (heat recovery type of course).

BTW: Washington is not really that cold ;)
