...a bit can be saved on heating costs with proper humidification.


ASHRAE 55 says a 48x48x8' house with R20 walls and ceiling would be equally
comfy at 69.4 F and 20% RH or 68 F and 50% RH. If it's very tight, with 0.5
air changes per hour, would "proper" humidification to 50% save energy?
But, too dry of indoor air causes all types of health problems such as
mucosal membrane irritation, nose bleeds, increased viral infections,
and more. Further, improper indoor humidification dries out wood
furniture and the house itself causing wall cracks and worse. So there
has to be a proper balance of humidity.

Humidifier ........ or a pot of water on the wood stove!
