Hot water heat, using baseboards, doesn't add any moisture to a house whatsoever. I think you are talking about steam heat, that adds a little moisture (or alot if a steam air vent is leaking).Originally posted by kc_srvs
Are you getting nose bleeds? I'm wondering why you need the Humidifier if you have hotwater heat??? Hotwater heat auto. puts humidity in the air.
Leaky houses are dry houses in the winter. Insulate the house, close the chimney flue, or replace old windows to increase humidity. I run a stand alone humidifier (copper baseboard heat in my home) and it's able to put upwards of 4 gallons a day into the home.
