I like your idea. Have you gotten it hot yet? Question number two, how big of a chest freezer are you using? I need 20 square feet or about 150 gal. I am wondering if yours is that large. I sure don't like the prices on solar thermal storage tanks.
Another question, How well does the PEX tubing work as a heat exchanger? Copper is probably better but pretty expensive. Anyhow I love your idea. Hope you don't mind if I steal it for my home.
