    Humidifier for Log Home

    Five years ago we built a 1750 sq ft Log Home in Southern New Brunswick and have been heating it with a Soapstone Woodstove. Last year we took advantage of a government grant and installed a Mitsubishi Zuba Central Heat Pump. The unit works well but the air is cool and dry.Shortly after the heating season started we started to have problems with cracking of the cedar logs and pine purlins. I bought a Honeywell Quickteam humidifier which has helped buy has to be filled 4 times a day and if I forget the humidity drops.

    I want to install a whole house humidifier attached to my HVAC, Our HVAC is in a 4 ft high crawl space so I want a humidifier that would require little serving . I am considering the Honeywell Truesteam 9 gallon humidifier. Would the Truesteam do the job? Does anyone have any input regarding humidifier and log homes?

    How many gallons a day is the current humidifier using/putting into the air.

    Is it possible that the heat pump was installed in a manor that fresh dry air is being bought into the house. And that should be fixed instead of just adding a humidifier.

    How many times must one fix something before it is fixed?

    I am presently using a Quicksteam Humidifier that I bought from Walmart it is rated as 4 gal/day. The outside wall is properly sealed where the piping goes to the heat pump so no air can enter.

    After the Heat Pump was inspected I had to have the house inspected so I can get the grant, they did an air infiltration test and it passed, actually they were surprised they thought there would be lots of air leakage in a log home.

    If a 4 gallon a day is doing ok, then the Truesteam 9 gallon a day should work fine.

    not suprising that house was tight after construction.
    it is after the logs dry & shrink that leakage occurs.
    testing the house today might would yield different numbers.

    best of luck

    4 gallons of water evaporated by a electric steam humidifier uses +10KW per day. $.10 per KW equals +$30 per month. Evaporative humidifier use 50% less energy if you use gas or HP.

    Bear Rules: Keep our home <50% RH summer, controls mites/mold and very comfortable.
    Provide 60-100 cfm of fresh air when occupied to purge indoor pollutants and keep window dry during cold weather. T-stat setup/setback +8 hrs. saves energy
    Use +Merv 10 air filter. -Don't forget the "Golden Rule"
