: : It seems more phase III's (instead of the boiler co tank) could be set up with the boiler water sides in parallel to provide buffer tanks and the domestic sides in series to provide infinite hot water. Then the whole operation could be held to about 150F.
OK....I actually answered my own question....I called Ergomax, and their E65 tank holds 72 gallons of water. I found a price on the internet of $2450. If this would save me substantial money in hot water preheating in the long run (as well as increasing our hot water supply) over piping the buffer with the $1200 Lochinvar tank, I would do it.
The main concern I would have is that the boiler tappings are 1.5". Would that cause any significant decrease in flow in the scenario where the return manifold and the boiler outflow are teed together at the tank? Would the 0010 still be the correct sized pump for the application?
Would a 72 gallon tank be large enough for my application?
