I Didn’t Have Any Excuses Left
My children used to complain that our pool was too cold to swim in. They wanted to swim at night, and at times when it was sunny and warm yet not warm enough to heat the pool. They begged me to buy a heater, but I resisted for a long time. I didn’t want to pay for electricity or gas, and I didn’t want to buy an expensive solar system. But when they told me about solar sun rings, I didn’t have any excuses left. Those miniature solar heaters, because they are made of vinyl, are really cheap. And once a person buys them, heating their pool is free.
