Daniel Rosing lives near the freezing area at the base of Mammoth mountain. He wants to be able to swim year round (yes, that is snow in the background). He got one of our small EZ Pools, added a gas heater and the SwimMill and now he swims in warm water daily for only s couple dollars a day. In comparison to a swim spa that would cost him five times as much to buy and twice as much to heat - we think Daniel made the right choice.
