New to the site and my second post...
Thought this new space heater product that has come on the market might be of interest to members having issues with maintaining heat and humidity.
I just received my order on this 3-n-1 (heater/humidifier/air purifier) Envion Humidiheat space heater, for medium to large rooms, from Bed Bath and Beyond (most stores are just starting to get their heaters in and may not have it yet but you can find it for sale online from the BB&B site and other vendors). This product won 1st place for the Home Environment Electronics category at the 2009 House Design Awards.

I have had it running for about a week on a Johnson thermostat and seems to be working well at maintaining heat and adding humidity to the BP room. I am testing Humidiheat unit out on its medium setting for fan and heat in a 11x10 bedroom (I have 11 foot ceilings so I thought this setting would be best to start with. So far I am impressed with this unit's capability to heat and add humidity to the room, but since it is new, we'll have to wait see about its reliability. My normal home humidity is usually 45-55% in the summer but drops to low 30s in Fall and Winter. Haven't played with all the heat/humidity/fan settings and combinations yet but, at the medium heat & medium fan speed setting and humidity selection on, I can maintain 76-78* I set the Johnson thermostat to (BP is currently tubbed in the boys room so I don't want it uncomfortable for them to be in so I lower the temp slightly at night). Unit is pretty quiet (compared to the regular "louder" fan my son likes blowing on him while he sleeps) and cool to the touch. Their are no digital guages or LEDs that might keep you awake at night. I will later test out how long it will take the low setting to get up to desired temp in this room (recent outside night temps have start dip in the low 50s so unit may stay on longer at the low setting in order to maintain the desired "higher than normal" room temp).
I'm hoping this unit resolves the BP (ambient temp) heating issues I started have once we started to get a drop from summer temps and that it saves money with the winter heating bill (for cost savings I like to let house temps drop to mid 60s and it that wouldn't work for my son's new BP). The bonus will be if it also helps with the kids breathing issues (exacerbated by the dry air and use of the heating furnace) brought on by seasonal colds,flu and allergies.
