Today the new Hayward H100ID1 100,000 BTU natural gas heater arrived and I plan to do all phases of the install myself, including the gas line and plumbing from the Hayward filter to the pool return. At this point I am NOT planning to use the solar panels ahead of the heater to supplement the heating process; I just don't have a good place to put them right now. If anyone else has experience with this operation and would like to share with me any cautionary tales before I embark, I would cetainly appreciate it ;-)
