"Planning" is the key word. Comments from time to time on the cost of fittings, plumbing, circulators, controls, etc. I knew a year in advance I was going to do an install of my Tarm and storage, did the plan on paper, and then started hunting for the fittings, etc. in *bay. Saved a small fortune by getting parts in advance, fraction of the cost of buying at the local hardware or plumbing supply store. Do the homework, save a bundle; and it's never too late to start. By planning in advance, you can wait for the good price or the steal and not pay top dollar. Cheers.
