Rheem dual fuel gas split humidifier recommendation?

[pondfishr]

Hello I have a 6 month old Rheem RGRL 95% efficiency dual fuel split gas unit and would like to add a humidifier. The unit is controlled by a Honeywell Prestige IAQ, EIM, Red Link thermostat system. Any suggestions for models function ect... Would be appreciated. Thank you

If you are having humidity issues, tightening the house is 1 way to solve them. Also lowers utility bills. Otherwise, I like a simple bypass humidifier like Aprilaire 600M or the like. The Prestige IAQ will run any of them just fine.

The house seems to be pretty tight. The indoor humidity level on the thermostat reads around 42%. Is this low enough to worry about it or should I leave well enough alone?

At 42% you don't need to add moisture. As the outdoor temp drops and the equipment runs more, that will lower but also the safe humidity level will lower too. You might hold off a bit and see if you really need the humidifier. These days, I think a lot of them are sold that aren't needed.

Tell us more about The size/location of your home and the number of occupants. A small home with several occupants may get enough moisture from the occupants. Larger homes with two occupants needs humidifier when the outdoor dew points are <30^F for extended days.

Yep, give it another month and see how the humidity is.

I don't see that your areas average DP is less then 30 for any real extended length of time.

The home is two story 1300 sq ft main 1/2 of that has 17ft ceiling, second level 600 sq ft plus full heated and cooled 800 sq ft basement 10' ceilings. We recently installed a 4 ton heat pump rheem classic 13 seer, 90k rheem rgrl 95%, Honeywell prestige therm. The main level also has an empire ventless dual face gas log set that is centrally located. We have the logs controlled by an independent thermostat. We dont burn them all the time. The basement has a ventless empire cast iron gas stove that my wife uses when she works in her office. It also has a separate thermostat. We do have a carbon monoxide detector. We live in middle Tennessee where the winters are relatively mild compared to northern locations. We do get cold here but not extreme cold. What is classified as a too low humidity level < 30? I assume the dp comment is referring to the dew point. My thermostat thinks anything below 40 percent according to the display setting. Also does carbon monoxide rise or does in concentrate at lower levels?

CO2 when hot is lighter then air.

Too low varies with the house and its windows.

Lose the ventless heater! If a CO alarm goes off, you are already poisoned. CO is slightly lighter than air above 32 degrees F.
