F*ck that. The only ice that needs to be in my world is the ice in my drink as the sun warms the lake up before I take a swim. In December.

Nobody has much used those old rooftop water heaters since the seventies. They never really caught on except among a few cheapskate DIYers. Seems like they were leaky and not terribly reliable. Butt ugly too.

I pay 3-5 Bucks a month for the natural gas to heat my water. It's doable. Better brains than mine have taken efficiency to new levels.

Out in the swamp I used LP gas and a 40-gallon tank, it cost me $62 a month there.

Good coffee, good weed, and time on my hands...
