Venting a room

[dperrin]

I've been wondering the same thing myself. The ideal solution seems to be a whole home HVR (heat recovery ventilator) unit. Seems like most new construction in Canada requires these nowadays. But it wasn't so when my house was built in the 1950's and retrofitting one to your entire home seems like it will be very expensive. I've been doing a lot of searching and they do sell single rome HVR's in Europe that would be ideal for a fish room, but I haven't found anywhere online that offers shipping to North America. You could always just vent the room with a regular bathroom exhaust fan that is controlled by a humidistat, but I'm curious to know what solutions other people have come up with.
