  1. Great show! I am planning to install a solar hot water system with gas back-up this fall. I had been considering a Rinnai on demand but am now concerned after heaing your comment about on demand heaters and well water. Could you elaborate on the problems and any possible solutions and/or suggestions? I would greatly appreciate any opinions or information on gas back-up for solar hot water systems. Thankyou.
