ID Hot Water Convector

in THE MAIN WALL
Our manager was at a church to work up a boiler replacement. Wanted to get the ratings from all of the convectors. Couldn't find any information on these units. He said they looked like multiple rows of copper fin-tube. I found some that were very close, but not exact.



It's a hot water system, so the connected load is only needed to determine water temperature and as a reference against the building heat loss.

    600 btu/ foot at 180 degrees what I would use.

    That's what we're going to fall back on, but the convectors have several passes of fin-tube. I wasn't sure if the rating would be greater than the total sum of all the passes individually.

    J-Star, check out Vulcans catalog, they have ratings for Double Tier Fin Tube

    Thanks!

    Looks like the closest so far. Thanks for the help.

    For my way of thinking, if the radiation is heating the building, and the boiler is too big, so what. It's nice to know what the attached radiation load is but the actual verified heat loss is more important. Don't we always say here to size the boiler to the heat loss in a hot water system and size the boiler to the installed radiation in a steam boiler?

    Just wondering.

    It's my experience that most old buildings are so very over radiated. The only reason to over boiler a church is because when they turn up the heat on Sunday morning, it is the same as lowering the outside temperature on a temporary basis. When the church fills up with human heat emitters, the building is again over radiated.

    In my opinion. Subject to change.

    Dual Rows:

    If it has dual rows, it has a much higher output than 600 BTU's per foot. And 1 1/4" fin tube is higher than 600 BTU's per foot.

    I agree. We're sizing the boiler to the heat loss. We just want to verify the radiation, and possibly modulate the water temperature to save some money. Makes them happy, and makes us look good.
