If my math is correct, you would have to use 290697.67 gallons of water @ $1.72 per 1000 thousand to equal $500. Let's figure a rate of 2 gals per minute with a warm up time of 2 minutes. This means you could warm up 72674 showers before reaching the $500 break even point. That's 199 years worth of daily showers! If figured at 5 gals per minute, it would be approximately 81 years.
