Heat buffer tanks and boiler roughed-in.

Millwright work is done.  Moving on to plumbing, electrical, and controls.

Portable work-bench with vise.

No stooping to tend firebox or ash chamber.

Tank pedestals for three 250 gallon (obviously) used former propane tanks.  Thee-inch thick high-density Styrofoam.  Supposedly good for 70 psi loading, I'm only asking for 25 psi.

Still missing the two pieces that will complete the boiler recirculation loop.  Lower two pumps are both return water injection pumps that will be controlled in stages to maintain minimum return temperature.

Near-boiler piping detail.  Closest pipe going nowhere will be return to buffer tanks from system loads.
