The type readings, priced apart by frame
| System type | Frame A reading | Frame B reading |
|---|---|---|
| Hot-only system, pro job | $575 | $200-$600 band |
| Hot-only system, unit alone | $325 | no unit-alone row by that name |
| Hot-and-cold system row | no separate row by that name | $200-$600 band, higher-end models above it |
| Filtration-combination row | no separate row by that name | $350-$1,400 total system investment |
Each reading is one frame counting of one system type in one job, never blended across types or frames.
The labor lines behind the type rows
| Row | Frame A reading | Frame B reading |
|---|---|---|
| Professional installation row | in the $575 figure | $150-$400 |
| Under-sink row, existing connections | in the $575 figure | $150-$250 |
| Pro time row | 3.0 hours | no time row by that name |
| DIY time row | 3.5 hours | no time row by that name |
Rows present in one frame and absent in the other are printed as absent, never filled from the other frame. The time rows stand in Frame A alone; the split installation bands stand in Frame B alone.
The totals behind the rows
| Total line, as published | Frame | 2026 reading |
|---|---|---|
| Pro job, as printed | Frame A | $575 |
| DIY read, unit alone | Frame A | $325 |
| DIY saving, as printed | Frame A | $250, at 43% |
| Unit and installation, contractor average | Frame B | $200-$600 |
| Total residential system investment | Frame B | $350-$1,400 |
The totals count the whole job behind the type rows, and no page adds type rows into one blended total. The frames count the same job on different bases -- a priced pro-against-DIY comparison at $575 against $325 for the unit alone in Frame A, against contractor and market bands at $200-$600 for the unit and installation, $150-$400 for professional installation, and $350-$1,400 in total in Frame B. That difference is named as a frame difference on every page here, never averaged.
The neighbours named apart
Scope readings price apart on the companion guide. Named apart, never a row here: the kitchen-faucet installation ticket and its add-ons line, tankless water heater installation, hot water recirculation pump installation, whole-house water heating, and water filtration installation, each in its own lane.

Is a hot-only job the same purchase as a hot-and-cold job or a kitchen-faucet ticket?
No. Each row prices one system type in one job, off a $575 pro figure and a $325 unit-alone figure in Frame A. The kitchen-faucet ticket, tankless installation, recirculation pump installation, whole-house water heating, and water filtration installation sit in their own lanes, named apart.
