Depends how tight your house is.

If its relatively tight, and you don't need a lot of moisture added to the air, then a powered humidifier will work fine.

Do you know what your humidity levels were last winter.

True steam! you will use less water. With power and bypass humidifiers whatever water is not evaporated goes down the drain and is wasted. Also if you do not have a 2stage or mondulating furnace that will run longer without satisfying temperature to fast, the power humidifier would be running long enough to meet its setpoint.

Im hearing that with TRUEsteam it will cost a fortune in electricity bills for the heating and the potential exisits for mould given that it may work independant of the funrance blower flan

april air makes a good one that has a outdoor sensor to read how dry it is outside i think it`s the 660 model it seems to work good

The Truesteam will indeed increase your electric bill.

It controls the furnace blower. So the mold worry is mute. Unless your installer can't read the install instructions.


A bypass will work fine also. Provided your installer knows what he is doing.

Im not so sure the true steam will increase your electric out of proportion. Given the fact that you will be humidifying with steam instead of water vapor the run time will be less.
Consider the difference between blowing water vapor across your heat exchanger or actually using steam. one cup of water becomes 18000 cups of steam so what will your actual run time be?
Besides they have a 5 yr warranty and shut themselves down and drain themselves.

If that 1 cup of water is 1 pound of water. Then it will take 970 BTUs to turn it to vapor after the water is heated to 212 degrees F.

So if the house needs 10 cups of steam a day for 30 days. Thats 85.26 KWHs for vaporization. And doesn't include the KWHs just to raise the water temp to 212 degrees F.

So just to vaporize he water, would cost $8.53 for 1 month, at 10 cents a KWH, and this would be the usage in a mild month. For a 6 GPD Truesteam.

The steam wand is installed in the supply duct. The Heat exchanger and blower section would never see steam. Also the humidifier would not have to run nowhere near as long as the power or bypass, so I don't think you would see a significant increase in your electric bill.

The 6GPD Truesteam, will take 1.15 (69 minutes) hours to turn 1 pound of 212 degree F water to steam.
The 9GPD will take .8 (48 minutes) hours to turn 1 pound of 212 degree F water to steam.
The 12 GPD will take .67 (40 minutes) hours to turn 1 pound of 212 degree F water to steam.

And they will all have used .97 KWs to generate that steam.
Time is not what determines cost. Amount of KWs consumed is.

Oh! But I thought he lived in Denver. so being that high above sea level would that not lower the boiling point from 212 degrees.

No its not.

So quit telling him it won't cost much because you don't think it will run long.

I guess if you wanted to calculate run time verses some other equation, what i do know is it is actually steam and not water vapor. The steam is a better medium to transfer the moisture to the air in this case. I never was a believer in bypass humidifiers, my opinion was they are better than nothing.

Add to that the cost of water, not much i will grant you.
