is it better to use hot water or cold water for a bypass humidifier / thanks for your input thanks jim
The water flow to a humidifier is so low (one gallon per hour), the water cools via the copper tube before the water gets to the humidifier. Even if the water was hot entering the humidifier, evaporation cools the water rapidly. The heat to evaporate the water comes from the warm house air. The wet bulb temperature of the evap pad cools to 45^F with 100^F warm air. One lb. of water needs 1,005 btus to evaporate. One lb. of 120^F water has 80 btus at best. So, save your hot water. Best to tighten up your home to slow the dry winter air from passing through. Also extend your fan run to time to allow enough time to humidify. Also avoid over humidification. The sign of max humidity your home should have is slight condensation on the lower edge of your coldest windows. Regards TB
Bear Rules: Keep our home <50% RH summer, controls mites/mold and very comfortable.
Provide 60-100 cfm of fresh air when occupied to purge indoor pollutants and keep window dry during cold weather. T-stat setup/setback +8 hrs. saves energy
Use +Merv 10 air filter. -Don't forget the "Golden Rule"
