    HTP Boiler

    Folks are pretty excited about it. It has a 6 to 1 turn down ratio.

    As I understand it, the tank becomes like a hydraulic separate and takes the place of the secondary piping.

    I think there is a primary pump on the boiler that pumps through the tank. The secondary piping to the system also pumps through the same tank. The idea is to keep the boiler hot so it doesn't condense as much.
