Every commissioned install since November 2011, ledger-style, with the field-data line for each. Three tracks open to full as-built detail — manifold maps, commissioning data, outside temperature on commissioning day, who designed it, who pulled tube, who set boiler.

Older tracks from 2011–2020 are kept in the bound paper ledger at the shop and can be consulted by appointment. Many of them are 1920s rehab work that we are still on call for, and the homeowners have asked that the field data not be published online. We honor that.
The biggest new-construction install of the 2024 season. Two-story timber-frame at 5,200 ft elevation, full slab radiant on first floor, staple-up on second, snowmelt at front walk and approach.
A retrofit driveway snowmelt added to a 1990s house in the lower Cottonwood Canyon, with its own dedicated plant and a 320-foot tubing run from the mechanical room.
Conversion of a 1908 cast-iron radiator system to a Navien NCB-180 with retained radiators, new outdoor reset, deletion of three monoflo loops, fresh distribution piping.
