Old gravity conversion

Started leaking a few days ago . We had an asbestos crew in there yesterday to get it ready . Notice the old sidearm coil - must've weighed 150 lbs. That's Sal ready to pounce .

    with the matching Riello burner . We piped a purge setup on the supply and return to isolate the boiler or to drain the mains if a vent needed replacing .We also piped in a bypass - there's way too much water in the system to not have one . We used 2 #30 Extrols because we do not stock 60s .

    Nice open basement , but the staircase was real tight and made a a quick turn down the side wall . We wound up carrying all the old sections by hand . I thought those days were over for me .

    Nice job Ron.

    Hope you have enough boiler to sell them an indirect when the water heater fails. With the advent of the "new" gas fired appliances for heating water, we've been sizing for the tanks failure. The cost and (with some) the thought of replacing the whole enchilada upon a misfire call, has the supply houses advising for it.

    You and your guys have to be the best TEAM going. Doing a job that large, from start to finish in 1 day is incredible. Keep the bar high. Chris
  • There were 3 of us

    Sal has been with us for 5 years and we got a newbie , George learning the ropes . This one wasn't too bad . Although the staircase was tight and the turn at the top was narrow , the driveway was right there . We also had a salesman there watching how we do things . I gave him a pop quiz on pipe sizes and he did pretty good . Thank you very much Clammy .
  • There was just one person

    living in the home , an elderly lady . If the gas heater goes , a (gasp) coil would be a good choice . We usually install a tee and plug on the header for a future zone or indirect , but theres plenty of space here to add anything in the future . Hey I fogot - this was in the basement too - an old GE fridge . Never saw one like it , looks more like furniture than a fridge , being up on legs like that .

    Thanks alot Chris , we do switch up partners almost every day , and it keeps the peace so to say . But we all work pretty good with whoever we are partnered with . A gravity system was a nice change of pace - except for the ripout .

    I have a question that you have more experience with . The way I piped the bypass to keep the return temp up - is that the proper way ? I know it's hard to see , I have the supply bypass going up to tee into the returns . Thanks for any help Chris .

    by pass

    Ron have you ever tried a system by pass instead of a boiler by pass i find with larger systems including gravity systems with low limit circ control the pump cycles and that by passing the system heats the returns and prevents shocking and short cycling of the pumps limits on oil i usally use a 8182 triple aquastat control with the low limit circ have a few out there with this set up anda few without which every year there plugged solid they just haver a 8184 i believe cold start aquastat and it seems that having a large amount of water in the system just makes the boiler condense until it,s up to temp but sooner or later they end up plugged.With that dual aquastat supply by pass set up i haven't had a large water content system get plugged or cycle off and on from low water temp peace and keep up the good work

    That's a \"Monitor Top\" fridge

    very popular during the 1930s, and a few are still running today. I think it got its name from the then-popular "monitor" roof vent fans.

    Monitor top

    I think GE stopped making them in the early 30's. It uses sulphur dioxide as the refrigerant. The metering device is a highside float. I have a 2 door model with instructions, still runs. These things make todays refrigerators sound like locomotives, they are very quiet.
