Using a heater to raise the bathroom air temperature: a moisture question
In my home I use a small, electric kickspace heater to raise the temperature in the bathroom during showering. The elevated air temperature allows for the air to hold more of the moisture and raises the window glass temperature, reducing condensation on that glass.
I am assuming that this elevated air temp gives the exhaust fan and the HRV exhaust more time to exchange that air and the moisture it holds. My question is this: by increasing the ∆T am I really just increasing vapor drive through poorly-sealed areas? The house was built 15 years ago and probably is not as well sealed at the window perimeter as I'd like. This is a timber-framed house with a SIPs enclosure.
