I'm looking to install a Natural Gas Tankless (condensing) water heater (likely Navien 240). I am planning the drain line (which will have a neutralizer on it to reduce the acidity). The installer & distributor say the condensate will be 2 Gallons per hour (which seems to be the manufacturers maximum number). I live in a desert area with a very low humidity (<15% normally) so 2 GPH seems excessive to me.
- Does anyone have any perspective on likely actual condensate volume?
- I'm planning on piping it away from the heater closet (on outside of house). If it is going through a neutralizer, is there any issue with letting the water flow into landscaped areas to water plants?
