I'll check into it. If it saves that much a month, would be worth the investment.I would have to find my invoice. They are a lot more affordable then when they came out several years ago. They save you alot of money in the long run as hot water is only produced on a need basis, and not fired up every single time the water cools off as a conventional hot water heater does. Projected savings is $50 per month or more depending on how much one uses hot water. With the horses, I am always using it, and am daily cleaning water buckets, and waterers and feed buckets. Space was also a deciding factor for me.

We want goats and possibly a llama, so it would definitely be used.
