>i got the 600 for 250 installed. did i pay too much?
maybe, compared to more air sealing (caulk, etc.) and some green plants.
humidifiers are expensive to operate in air-leaky houses in cold climates,
counting the space heating energy needed to evaporate water.
if you don't like green plants, you might use a humidistat and a solenoid
valve from an old washing machine and a soaker hose on the basement floor.
and maybe add a dehumidifier (a heat pump with a cop of about 1.6) upstairs,
in a house with electric resistance heating.
