Laziness Can Be Expensive

Sometimes I just don't want to take the time to reduce and then increase the size of piping between boiler and manifold even though it's way overkill and more expensive.

8.33 lbs./gal. x 60 min./hr. x 20°ΔT = 10,000 BTU's/hour

Two btu per sq ft for degree difference for a slab

    That extra $8 probably isn't much of a concern when they just spent 5 figures to heat 600 sq ft

    More when you include the larger air eliminator and pump flanges.

    Well, I think I would have done the same.

    Nice work.

    You can choose to do what you want, but you cannot choose the consequences.

    Nice.
    I love that boiler. very simple but effective.
    BTW... where does the expansion tank connect into that piping?

    I have done the same sometimes because it eliminates reducers.

    I like reducing tees or 90s (with fitting reducers if propress) and try to avoid bell reducers

    The blue x-tank is for DHW. The heating tank is upper left, almost out of view.

    ...........and I just realized I'm pumping towards the expansion tank. Rookie move and I'll change it when we go back.
