Thanks for your and everyone elses input re:switching to NG and getting solar. Turns out my utility pays a (0.04) premium for green energy. Still not sure it's worth the investment yet, turns out you need a battery system for the panels to power the house during an outage (say, a hurricane), even if the sun is shining. Still thinking..

Going to switch to instant gas water heater and use hot water heater enclosure as closet, and add utility paid insulation.

Have you looked into improved windows ?

Also attic circulation, a ridge vent and soffits are the best solution.

Best Hopes,

Alan
