Does anybody have any experience with a heat exchanger in a house to get rid of humidity? I don't know where the extra humidity comes from but it stays just over 60% with the dehumidifier running in the basement. Sometimes over 70%. If I turn the dehimidifier up it freezes up. Thanks

I'm guessing you don't have a forced air gas furnace or you wouldn't have this problem. Mine keeps my house at 35%
What form of heating do you have?

My house is about 3 years old with a gas forced air furnace. There are 3 adults and 1 infant in this 1550 sq. ft home not including the full unfinished basement. The humidity has probale been high from the beginning but we did not notice it until I foung the finish gone on the bottom of the window jambs and on the patio door. If you need more info to help me solve this problem let me know. Thanks

You have a three year old house. I have heard of tight well insulated houses that retain moisture. How is it in the summer? Do you have whole house air conditioning?
Four people can develop a lot of moisture in a closed house.
If you don't have ventilation for cooking, showering, and a dishwasher all this moisture can accumulate.
With a new house you probably have a 90 plus furnace going out the wall, but have your water heater (gas) checked to see that it is venting properly. This can put alot of moisture in your house, and carbon monoxide and dioxide too. Make sure all your exhaust fans are working: Over the stove and the bathroom and see if your dryer vent is clogged with lint.

Does your heating system have a humidifier? If yes, turn it off.
In the bathrooms where showering occurs, do you have vent fans that discharge to the outside of the house? It is important that they vent to the exterior of the structure, and that they get used. Let them run a good 15 minutes after the shower is over.
Does the vent fan in the kitchen discharge to the outside of the house? If yes, use it when cooking. If no, instal one thaty vents outside.
If the other areas are problems, correct those first. If that doesn't do the job, then consider the installation of the heat exchanger.
Do a google search on "energy recovering ventilators".
