Part 2

Hi, I'm very interested in your system of heating your grey water tank. What heater do you use for heating the glycol? If you like that heater would it be possible for you to post a link to their website?

Hi there, I used an Espar hydronic heater and bought it from Rixen Enterprises. www.rixens.com Their customer support is top notch as its a complex system. Good luck and shoot any other question.
