    Nice work.
    But I must say I hate to see all that exposed copper mounted on un insulated masonry. (unless its insulated on the outside)

    95% system mounted on a giant heatsink = ?%.

    Install looks nice and clean though.

    Would have taken the five minutes to paint the board though.
    The heat is included in the rent, this building is really old and there is really no easy way to split up heating. As for the paint, I'll be posting more boiler pics in the future and we got a good one going in soon. Thanks

    Could have saved a pump by just using the buffer tank as your hydraulic seperation. I know, the low loss header comes with the boiler, which is why it always gets used.
    That's an awesome point Charles! I suppose we would just have to fit in the pump and piping for the domestic but that would work. It does seem rather redundant now to have two points of hydraulic separation.

    I think you have 1 to many spirovents also, the buffer tank has one.

    Interesting, I'll have to look that up. Like Charles had mentioned.... it should be taken care of at the zone valves.

    A boiler drain between the ball valve and the x-tank would be nice for service.
    I actually saw a drain like that on another boiler and thought it was a great idea.

    No they don't.

    I put this up on the wall of pride cause I'm happy with their work. I'm not sure what your thoughts are but I have no bad intentions in this posting.

    Hot water can flow out of the supply or return, also boiler side could gravity flow through boiler.

    There already is a check valve in the boiler pump, besides a little gravity flow through the boiler is a non-problem anyways.

    The boiler buddy should never be maintained at a certain temp, it is just buffer. The boiler only needs to fire when a zone is calling. Buffer tanks are ONLY necessary when the heat loss of the smallest zone is less than the lowest firing rate of the boiler.

    Example; If the boiler modulated down to 15,000 btu and the smallest zone has a heat loss of 16,000 btu's, a buffer tank is a waste of money.

    What I meant was on call for heat to the tank is maintained at a certain temp, not without a call for heat. I think I'm starting to split hairs here and I'm sure there won't be any or enuf gravity to make a difference it's just how it shows to install them in their manual.

    the board is mounted to an interior wall. there were no plans to insulate. i agree, it's a lot of copper but you have to realize too that this is a really old building downtown and there is no insulation in the walls. honestly, when comparing to the previous system, this new system will save the building owner tons.

    I do not like ball valves on expansion tanks, but thats me. Very nice work though! I get laughed at for painting floor heat manifolds red and blue.

    Also no condensate drain on the exhaust close to boiler

    You like to drain half the system with the tank and have to fug around with air in the system?

    Hey chuck reading this months later I can barely understand what I said, let alone expect you too lol.

    The buffer tank is only heated when there is a call for heat.
