Reversing the P/S connections?
So typical P/S shows the boiler return pulling return water first, then the supply dumps into the flow last and of course there’s some mixing of supply into the return. When I tied my CI oil boiler into my piping I reversed that so the supply hits the return water first and that mix is sent to the return and manifold supply and all flow goes the same direction at the tees. This seems to work great now that I’m on oil waiting to set my new LP tanks. Am I right that this will keep the return temp up?
Just a guy running some pipes.
