Hello,

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

50% RH is "high"?

I guess to me it is...I also have an indoor swimming pool in the back yard
(not attached to house) and I keep the RH in that building to 30-35%...I
park my BMW in the same building with no issues.... Jim



They run computer rooms at 50%. I guess I am just more used to a
higher number in a home. I just looked and it is 44% in here right now
and my lips are cracking and my throat feels dry..

Hi,
R.H. is function of temperature. Computer room is for the machine not
people. Too low humidity will cause static discharge and it is harmful
to the machines. Here in winter, most of time at home we keep it around
25% when it gets real cold(like -30C)
