Consider low-high-low burners on your next replacement.

For years we have designed boiler rooms consisting of two oversized boilers with fully modulating burners. The idea was that the boilers could “loaf” along at low fire because we were told they were more efficient at low fire. I think it is time to rethink those strategies.
The BIMForum released the first-of-its kind standard establishing definitions for how complete BIMs need to be for different stages of the design and construction process.
