The gas heater shown in the attached picture has been installed since we bought our house 4.5 years ago. Best I can tell, it was installed when the house was built in 2001 and never used. There is no propane tank in my yard and no NG in the neighborhood. We have no intention to use it and based on my recent misadventures with acid, the core is likely shot.
To remove it, I would simply plumb down pipe from the solar directly into the valve on the lower right of the picture, bypassing the 2 sections of pipe the run underground, right? I have the right hand input on that valve (the one closest to the filter) labeled "input from filter" which means it would go through the solar, then into the gas heater, then back, right? I don't want to kill the plumbing...
Thanks for the help!
