I am shopping for a tankless water heater. One of recommendations that I found is that you softener the water before it goes to the heater. This will help extend the heater's life. I am concerned that salts or potassium chloride will not be eco-friendly. I did not find water softeners listed as a product category here on green huddler. Anyone know of an eco-friendly alternative to soften water?
