I have a 2600 sq ft 4 level split home in Canada. It was built in
1985. This past spring we replaced our very non-effecient furnace with a
Tempstar 95% effecient gas furnace. It really is wonderful as the old
furnace would cause the house to feel sort of drafty and basement was
always cold etc... Now I have this furnace that I love to bits BUT now
since it has gotten colder outside these past two weeks, we have kept the
doors and windows closed and now have a high humidity problem inside the
home IE: fogged up windows (triple pane)...air basically feels
clammy...bought a humidistat and the house is sitting at around 50%
humidity.... we use bathroom fans in the shower, and have a fan over the
stove when cooking that we use all the time...we keep lids on pots on the
stove etc...We have no children and only the two of us in this home so no
long lingering showers by kids or anyone else....
I don't want to have to buy a dehumidifier over this new furnace..
sort of defeats the idea of trying to be energy effecient... Thinking of
trying to duct in an outside air source to feed the furnace?
Thoughts? Thanks... Jim


*If the unit is the type that I am thinking of you should have two PVC pipes
coming off of it. One is for fresh air and the other is exhaust. The
exhaust pipe must be pitched (Sloped downwards slightly) towards the outside
so that condensation will drain outside and not into the unit. Check to see
if that is so. Also if your unit is not pulling air in directly from the
outside it would be a good idea to bring fresh air into the room.
