  1. Where to put the high efficiency filter ?

    My wife has severe alergies.

    We'd like to install 2 of these big high efficiency filters into the HVAC system in our house.

    We ran a blower door test and did some infra red camera snooping yesterday.

    The house has a leakage rate of 0.215 volumes at 50 Pascals. It has an equivalent open area of 172 square inches. ...

    The home is airtight. We found a "fanless" heat exchanger hidden in the ducting allowing 150CFM or more into the house. Thus the low humidity.

    The fanless heat exchanger isn't high quality. I'm...

    I had a journeyman HVAC specialist in the house yesterday. He said its "as tight as a drum" leak wise. In his opinion a blower door test isn't needed.

    We inspected the existing Honeywell...

    It turns out that a house needs way less than 5 air changes per hour. More like 0.3.

    The required ventilation rate is then 52,000 ft^3 x 0.3 = 260 CFM.

    I'm thinking of installing 2 VHR...

    Thanks for the advice, TB.

    I don't think there is any way that these homes (current one and the one we are moving into) have 150 CFM of fresh air infaltration. They are built way too tight.

    I think I'm going to install an AprilAire 700 in each of the heat exchangers for the "normal" humidifying load and back them up with an AprilAire 800 downstream in the duct as needed.

    I'll run...

    A blower door test is an excellent idea. I'm waiting for call backs from 2 such service providers.

    Lets assume these houses are pretty decent leak wise. Given the natural gas bill for the house...

    Yes, in both the house we currently live in and the new house. The new house has the booster fan setup, our current house doesn't.

    The HVAC room is in the basement on both of these houses. ...

    I'm a fan of those systems too. My uncle has it in his house. However, it would be nearly impossible to retrofit that into our new house.

    That is a very interesting idea. The new house is getting a Zwave automation upgrade, including the thermostats. It probably wouldn't be too hard to integrate control of the humidifiers into the...

    They appear to have insufficient capacity to keep the humidity up.

    FWIW, we currently live in a similarly sized house. Probably 4500 ft^3 finished on 3 levels, 10 foot ceilings on main and...

    Its appears to be a very well built...

    Would the AprilAire 700 be better than the typical drum style evaporative humidifiers ?

    It seems to have a similar control to the 800 model, ie outside temp sensor.

  15. Best big home humidifier setup. (steam versus evaporative, etc.)

    We just bought a new (to us) house in Calgary, Alberta. Its a 2 story, built in 2007, 5,000 ft^2 finished, including the basement, 9 foot ceilings throughout. Hardwood everywhere on the main and...
