went out on my own a few months ago posting pics of 2x systems i did recently one in rich area has king valves and such lotta space so could really make it neat

second was for a charity they had lived there 8 years system never worked properly only 4 convectors single pipe counterflow i folded drop inside boiler footprint due to space consideration

looking for comment from others these two are new concepts i have been trying since my recent purchase of a ridgid 300 with nipple chuck

basic drop header i pre build up to crossover from tee to equalizer i leave open then only have to make up loop side and tie to header union on drop off equalizer into loop lets me complete that easily i paint then insulate like to show the paint pics looks nice feed is off hot water side of hot water heater also

what came out and went in

Nice! Probably the only thing Id've done different is in the counterflow, I'd have turned the tee 90 degrees and fed from the top. That way I'd have a true drip off the bottom.

Main question is how do they work?

Should've remove the header from the old boiler (or 3 boilers ago) in the counterflow and added a drip instead of using the equalizer in the old header for the drip. It will probably work ok that way but you can get weird balance issues sometimes with that configuration.

they work great first customer also had a radiator not warming and another leaking, the first company i worked for was my competitor on bid got those fixed (easy just vents) and her system works a+++

second one the counterflow had coin vents on main !?!? i put in real vents and its only 4 convectors like 68 sq ft steam its tiny so it works well kinda never worked before i just out it in 2 weeks ago did ok on cold snap im doing 2nd skim tomorrow and gotta upsize 1 radiator vent speed it up

as to the 45 degree stuff that comes from the guy who taught me was his style and im decent at math and got a power threader now so its kinda a style choice but i can see were it may affect the counterflow, i think in this case because the systems so tiny i get away with it on condensate return

The 45's are great, they keep the pieces of the header from sitting flat so they can collect water. This is the part that isn't quite right, it is the header from an old boiler. The drip for the counterflow should come off a tee from the bottom and the steam should go straight in from the boiler instead of having to take the branch of a bullheaded tee:

ok now i see, wish i knew that as main is 2" so would be easy

this was boiler funded by local donations and operation stand down and its a very nice family i may return in spring and improve that

its a tiny tiny house and system, im pry gonna do some other work there in spring their sewer line thats cast is about to go

and i like that makes a lot of sense could do 45 offset on condensate to jog over with offset, headers easy just up and over, i did pitch that tee for condensate and as stated smallest boiler is still kinda oversized so it works which is what matters, but im here to polish those last couple rough edges can never know ti much just enough to get by sometimes

really makes sense to original boiler was old tall beast i know relize how many times iv done this is disgusting… but at least it was always in black iron 😜
