What is it???

This red devise was sitting next to the old indirect. It has a coil of some sort, and several taps. Ideas???

It's an old side-arm heater

kept the tank hot by gravity circulation.

that's a

that looks like one of the smallest B&G tube heating exchanger....

So the supply to the tankless passed through it as well as the supply to the zone? The system was converted gravity when I changed it over to modern circs & controlers. It had HUGE B&G 2-stage circs for small 1-bed apartments. Should solve the air and velocity noise issues. Would not pony up for a new boiler. I respectfully had to go with my own gut feelings and pipe the supplys and returns into one manifold, against Weezbo's advise. We'll see. I felt this created a more even distribution of cold return temps.

It was mounted on the side of the boiler

boiler water circulated thru it by gravity, and so did the tank water.

it looks like the conversion came out well.

the side arm was real popular a while back...many of the older boilers had additional stress hanging off the pipe.... consequentially, the tapping's strong support was being undermined over time by even more stress...having seen enough of that i mentioned it....

Monday ,i am going to go check on a very similar lash up although it is more "modern"....i get a pic ...The young guy works as an electrician. he, his brothers and dad hold down quite a bit of work in the community every year...he likes the work that i do and asked me a while back what way to go...so we will lose the old boiler for a slightly more recent attempt at heat exchange.....For whatever the reason workmen that do good work recognise what they see and order their steps accordingly...too bad not all homeowners see things day to day that work right... were that the case ,there would be a lot of energy savings happening in our country.

Today, my neighbour stopped to let me know that he manged to get the old Crane out of the Crawl pit/boiler room...so i have to get that all together Monday too.

something i will roll by you... just before the house was sold to my neighbour someone poured new anti freeze in the boiler after a HEAVY dosage of boiler solder.... no oil in the tank the water lines broke and the service latterals plasic meter cracked and leaked all over this pinner boiler room...it is sad buh i could not tell this immediately in the winter when i fired the burner for a few seconds.... all i knew is, it needed oil, it had what seemed like very clean anti freeze in it and the firebox was sooted ,bAd. the boiler was a casualty long before he bought the place.... i got to get me a New set of X-ray glasses.
i am getting older and my eyes no looky too good well, Good luck. this vacation thing just doent seem to be working out .....*~/:)
