Portage & Main / Is a 28-40 right for me?

« on: August 12, 2017, 08:48:00 PM »

Im about to pull the trigger on a new stove. Iv been eying a 28-40 for a couple years now to replace a very old taylor 450. Im in nw Pa hour south of lake erie. Usually dont get -degrees f, but if it does its only during nights and 10-15 below. Maby last a few days to a week. 2,800 sq ft house sided n pretty insulated.also wanting to do dhw in series before hx. My taylor burns a good 8-9hours when cold (say teens or 20's).i know the p&m has a bigger box, im just worried about the small water jacket even though its designed for a reason. Think ill be ok with this?

I'm! Goin nuts here. Putting in new P&m bl 28-40. And trying to figure out best lines to buy as far as size. I have two water to air hx (because of an addition) and id like to do domestic hw during winter. Do i make 1" manifolds supply and return for all 3 ? Or i can buy 1" & 3/4" and do 1hx with d hw in series and put the 3 /4" to my smaller hx. Will a1" manifold in/ out be ok with seperate pumps for each hx?
